Shale gas has emerged as a significant source of natural gas due to advancements in hydraulic fracturing and horizontal drilling technologies. This extraction method has facilitated drilling and production activities in regions previously untouched by oil and gas development. Hydraulic fracturing, a well-stimulation technique suitable for low and moderate-permeability reservoirs, relies on the successful drilling of horizontal wells and the creation of multiple hydraulic fractures to ensure economic viability. While shale gas presents significant energy production opportunities, concerns have been raised regarding its environmental impact. To mitigate these risks and determine the most effective approach for shale gas extraction, alternative fracturing technologies are being investigated. Notably, a considerable number of perforation clusters in shale gas horizontal wells do not contribute to production, highlighting the potential for refracturing. Therefore, a comprehensive analysis is required to evaluate the performance of hydraulic fracturing and alternative fracturing technologies in shale gas wells, considering factors such as cost-effectiveness, environmental impact, and gas extraction efficiency. This article aims to evaluate the hydraulic fracturing technology's capability to enhance gas recovery in shale gas formations as well as its environmental implications. The focus of this research is primarily on the hydraulic fracturing technique employed in shale gas development, its production capability, and associated environmental concerns. Through a systematic evaluation, this study provided valuable insights into the potential of hydraulic fracturing in maximizing gas recovery while addressing environmental challenges in shale gas formations.

The adverse effects of the combustion of fossil fuels on humanity and the environment have made it vital to discover eco-friendly, sustainable, and renewable energy alternatives. Globally, there exists loose biomass, which is agricultural and cultural waste that can be utilised to produce briquettes, a type of solid fuel. Briquettes have played a significant role in the energy generation economies of both developing and developed nations. The production of briquettes involves a series of activities, including collection, transportation, storage, processing, and densification of the feedstock to meet predetermined quality parameters. Rice husk, corn stalk, wheat straw, cassava stalk, groundnut shell, olive husk, palm kernel shell and coconut shell are among the feedstocks for briquettes. In order to increase the cohesive strength of the briquettes, binders are incorporated during the densification process. This study aims to investigate the current state of research regarding the utilisation of biomass-derived briquettes as a viable substitute for traditional fuels. To achieve this objective, a comprehensive analysis of recent literature published between 2017 and 2023 is conducted. This study encompasses essential subtopics, including the accessibility of biomass, the selection of binders, the parameters of the briquette process, and the equipment used for briquetting.

Coal has become a feasible source of rare earth elements (REEs; the 14 stable lanthanides, scandium, and yttrium). It is believed to contain significant amounts of rare earth elements, making it a primary source of REEs which serves as basic raw materials in the production of renewable energy. This review established the feasibility of recovering REEs from coal using acid leaching method. It discusses; the sourcing of REEs from coal, the applications of REEs and acid leaching as an effective hydrometallurgical method for extracting REEs from coal. It also examined the efficiency of methods used by other researchers in extracting REEs from coal. However, the potential of acid leaching as a solution to issues such as: difficult leaching conditions, low recovery and the use of expensive chemicals has not been fully investigated. For a better choice in the extraction of REEs from coal, more study and review are necessary.

(NJEAS, 2024-04-09) Blessing Alade; Petrus Nzerem; Ayuba Salihu; Oghenerume Ogolo; Ajiri Otedheke
For a drilling operation to be successful, the drilling fluid performance must be optimized. This research study the use of degradable agricultural waste namely cowpea skin powder (CSP), sugarcane rind powder (SRP) and yam bark powder (YP) as additives for fluid loss control. The elemental composition of these food wastes was determined using SEM. Proximate analysis was performed to investigate the content of moisture, ash, nitrogen, protein, volatile matter, fixed carbon, bulk density, specific gravity and pH. The local additives were used at 1% (5grams), 3% (10grams), 4% (15grams) and 5% (20grams) each. For CSP fluid loss increased at 5g and 10g (1% and 3%), by 14% and 9% respectively, at 15g and 10.6g, fluid loss decreased by 33% and 36% respectively. Using SRP of 5g increased fluid loss by 12% but there was decrease in fluid loss with 10g, 15g and 2g in these percentages; 14%, 33% and 37% respectively. YP resulted in fluid loss at 5g giving 1.5% loss, 12% loss with 10grams, 16% fluid loss with 15 grams and 33% filtrate loss with 20grams. Overall, SRP showed best fluid loss performance with 20grams (5%), resulting in 37% fluid loss decrease followed by Yam bark powder at 20grams with fluid loss performance of 33%. The least performance was by CSP at 5grams (3%) that increased the filtrate loss by 14%.

(NJEAS, 2023-10-01) Malut Abba; Abdullahi Gimba; Ayuba Salihu; Petrus Nzerem; Ikechukwu Okafor; Khaleel Jakada; Joseph Chior
The prevalence of heavy metal pollution in oil and gas producing areas, Niger-Delta Nigeria, due to drilling activities in some oil and gas sites has resulted in the pollution of an immeasurable area of land and water. This study appraised the level of environmental menace caused by heavy metals in water-based drilling fluid waste. It involved an oil and gas site where drilling activities were taking place and settlement with no record of drilling activities served as control. In the drilling sites, two composite drilling fluid waste samples were collected before and after treatment and analyzed for cadmium, chromium, iron, nickel, lead, and zinc using flame atomic absorption spectrophotometry. The measured concentrations of the heavy metals in drilling fluid wastes were then used to determine the pollution and ecological risk posed by heavy metals. The thermal desorption treatment method was used. Their concentrations before and after treatment of the drilling fluid wastes were in the order Fe > Cr >Zn > Cd > Ni > Pb and Fe > Cr > Ni > Zn > Pb > Cd respectively with Cr, Fe, Ni, and Pb having their concentrations higher than permissible levels in water after treatment and responsible for most of the total potential ecological risk. The PLI (Pollution Load Index) before and after treatment were 0.0463 and 0.0017 respectively. There was a drastic decrease in potential pollution levels after treatment. Also, all the several pollution indices studied revealed that the drilling sites were contaminated with Cd and Cr. This reveals that drilling sites cause further risk of heavy metal pollution. The correlation analysis of heavy metals assessed is between 0.9 - 1.0 suggesting that all the heavy metals assessed showed high positive correlation coefficients at (p < 0.05) and likely originated from the same source of drilling activities in the study area.

(International Conference on Multidisciplinary Engineering and Applied Sciences, 2023-02-02) Serifat Olamide Adeleye; Adekunle Akanni Adeleke; Petrus Nzerem; Peter Pelumi Ikubanni; Ayuba Salihu; Adebayo Isaac Olosho
Numerous agricultural byproducts, such as rice husk and straw, bagasse from sugar cane, palm kernel shell, wheat husk and straw, corn cobs, etc, are highly desired for the production of renewable energy and are seen as potential raw materials for high-value products. Because they can be used to extract quality silica and Calcium oxide for borosilicate glass production, this research has demonstrated that these wastes have a significant end value. X-ray diffraction (XRD) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), and X-ray fluorescence spectroscopy (XRF) were used to characterize the calcined waste eggshell and wheat husk ash for crystal type, compound identification, and chemical composition. The findings demonstrated that the amount of silica and calcium oxide obtained from agricultural waste could be a suitable alternative source for making glass, with calcined eggshells having a calcium oxide content of 91.7% and wheat husk ash having a silica content of 71.3%. The potential for utilizing the CaO and amorphous silica in the formation of glass is thus intriguing.

This study assesses the compositional analysis and characterization of eight non-edible plant biomass identified as a potential feedstock to produce carboxymethyl cellulose. The materials' contents were ascertained by gravimetric analysis, and they were further characterized using Fourier transforms Infrared spectroscopy. According to the research, cellulose was present in substantial amounts ranging from 33 % to 41 %, with sugarcane bagasse having the highest concentration. The percentage of hemicellulose ranged from 18 % to 28 %, with corn cob having the highest percentage. Also discovered was that lignin content varied between 9 % and 22 %, with mahogany having the highest amount amongst the samples. The FTIR spectroscopic analysis of all eight samples reveals a broad band at around 3300 cm-1, which is caused by the stretching vibration of the cellulose's O-H groups. The observed peaks at 1600 cm-1 and 1500 cm-1 correlated to the hemicellulose and lignin's respective C=O and C=C stretching vibrations. Additionally, a significant sharp peak that matched the stretching vibrations in the skeleton of the pyranose ring, C-O-C, was seen at roughly 1050 cm-1. Thus, the findings of this study indicate that all eight samples can yield a respectable amount of cellulose, suggesting that these wastes may serve as feedstocks for the creation of biopolymers like carboxymethyl cellulose (CMC).

(ICMEAS, 2023-11-01) Ayuba Salihu ; Ikechukwu Okafor; Aniezi Okoro Daniel; Abdullahi Gimba ; Petrus Nzerem
The Determination of the optimal blend ratio of hydrogen in natural gas systems using physical properties as a basis is an important research topic given the increasing use of hydrogen as an alternative fuel source. This research aims to determine the optimal blend ratio of hydrogen in a natural gas system using physical properties such as its Composition, Heating Value, Density, and Wobbe index as the basis of evaluation. Samples of consumer-grade Natural gas and clean Hydrogen gas were sourced in Nigeria. Both samples were used for blending and laboratory analysis. The blend volume ratios of Natural Gas (NG) and Hydrogen analyzed were 9:1, 8:2, 7:3, 6:4, & 5:5 using a Gasometer and Gas Chromatography Machine (CG). The experiment results provided valuable insights into the potential feasibility of replacing natural gas systems with a Hydrogen-Natural gas blend. The result obtained indicated about 2.06% reduction in percentage methane content, 26.35% reduction in gas density, 19.97% reduction in heating value (HHV), 5% reduction Wobbe index for every 10% increment of Hydrogen Ratio. This implies that blending carbon-neutral hydrogen gas into the natural gas systems for the purpose of decarbonization requires adequate compensation for expected changes in properties like heating value, flow dynamics, and process handling. The EUROMOT specification recommends that the percentage change in the wobbe index should be within the limit of +4% and -4% as an acceptable limit of interchangeability of fuel gas. Using the EUROMOT specification on Wobbe index, further numerical analysis affirmed that Natural Gas blended with as much as 25.74% Hydrogen can effectively be a substitute for fuel gas systems that are presently using Natural Gas.

As the world grapples with the challenges of resource scarcity and sustainability, the need to develop indigenous raw materials has gained paramount importance. To achieve self-sufficiency and reduce dependence on foreign sources, harnessing hydrometallurgical processes to extract valuable elements from ores presents a promising solution. Raw gypsum from Postikum, Nigeria, was leached in hydrochloric acid to obtain a pure calcium sulphate dihydrate. The dissolution kinetics have been reported elsewhere. This present study focused on optimizing the recovery of pure gypsum by varying acid concentration, temperature, and solid-liquid ratio. Additionally, the recyclability of regenerated hydrochloric acid was tested. The characterization of the raw gypsum ore (RWG), leached residue (LR), and recovered pure gypsum (RCG) was done using SEM-EDS, XRF, and XRD, respectively. The recovered gypsum was characterised by a brilliant white colour in contrast to the initial brown colour of the ore. XRF results show that RWG contains 50.48% SO3 while RCG contains 57.72 %. XRD results revealed that RWG contains gypsum, magnesite, mordenite, witherite, and calcite, LR contains mordenite, witherite and quartz while RCG consists of gypsum crystal phase only with no impurities. Remarkably, 85% RCG was successfully recovered at the fourth recycle stage of HCl lixiviant. These findings demonstrate that hydrometallurgical treatment of gypsum ore with hydrochloric acid can produce very pure gypsum.

(NJEAS, 2023-10-12) Ayuba Salihu; Ahmed Abubakar; Petrus Nzerem; Abdullahi Gimba; Khadijah Ibrahim; Ikechukwu Okafor; Khaleel Jakada
In compliance with environmental laws and safety rules, oil and gas companies have taken necessary steps to eradicate the use of toxic chemicals conventionally used in drilling muds, thereby promoting biodegradable alternatives. This research was carried out to investigate the effect of two banana stem samples; Raw Banana Stem (RBS) and Delignified Banana Stem (DBS) as potential and proficient viscosifiers and fluid loss control agents in water based mud. The rheological properties evaluated include plastic viscosity (cP), apparent viscosity (cP), yield point (Ib/100ft2) and gel strength (Ib/100ft2) at 10 seconds and 10 minutes. Filtration loss properties evaluated include filter cake thickness (mm) and fluid loss volume (ml). Each drilling mud sample was prepared using 350 ml, 20 g bentonite and varying contents (g) of carboxyl methyl cellulose (CMC), RBS and DBS. A mixer was used to mix the mud homogenously; the rheological properties were calculated using a viscometer while the filtration loss properties were calculated using a filter press. The results and analysis were compared to the effects of commercially available carboxymethyl cellulose to validate its properties. RBS and DBS improved the rheological properties of the mud sample contents of 3 g, 5 g, 7 g and 9 g. At contents of 5 g, 10 g, 15 g and 20 g, RBS and DBS samples provide significant fluid loss control and their results are similar to the results of CMC. RBS has a fluid loss volume increase of 6.84 %, 5.69 %, 17.12 % and 8.06 % from CMC’s results at slightly similar filter cake thickness while DBS has a fluid loss volume increase of 15.59 %, 15.09 %, 27.55 % and 15.35 % from CMC’s result. The data obtained from the experiments showed both banana samples can be used as environmentally friendly viscosifiers and fluid loss control agents.

Drilling mud is susceptible to contamination, particularly from cement, yet monitoring its characteristics and implementing control and remediation strategies is critical for its performance in safe and cost-effective drilling operations. This study presents an experimental investigation into the evaluation and treatment of cement contamination in Water Based Mud (WBM). Four mud samples were prepared and three were contaminated with 4g, 8g and 12g of cement. A chemical treatment using 6g of sodium bicarbonate was applied as a remedy for contamination. The Rheological properties, mud pH and mud densities of the contaminated and treated Water Based Mud at temperatures of 35°C, 55°C, 75°C and 95°C were determined. Furthermore, the elemental composition of samples of contaminated and treated Water Based Mud was determined using an X-Ray Fluorescence Spectrometer. From the results obtained the mud density increased with a rise in cement concentration for both contamination and treatment with the exception of 8g cement concentration at 75°C and 95°C and 12g cement concentration at 55°C and 75°C where a decrease was observed in the treatment process. The yield point and 10second gel increased for both contamination and treatment process. In contrast, the 10minute gel decreased for both contamination and treatment process. With some exceptions, increasing cement concentration resulted in a decrease in plastic viscosity, whereas treatment with sodium bicarbonate resulted in an increase with some exceptions. The mud pH for the contamination process increased as cement concentration increased, while treatment only marginally increased it with exception of 12g at 75°C and 95°C where a decrease was observed. Sodium bicarbonate treatment improves stability by decreasing excessive calcium and lime contamination from cement, reducing pollutants and enhancing the pH stability of the drilling mud. Additionally, results from the mud characterization indicates a higher percentage of 17.962% lime (CaO) for cement contamination and lower percentage of 15.710% lime (CaO) for treatment with sodium bicarbonate which agrees with literature for the treatment process.

(NJEAS, 2023-09-20) Petrus Nzerem; Khaleel Jakada; Mohammed Shariff; Abdulquddus Ozigi; Ayuba Salihu; Ikechukwu Okafor; Steve Adeshina; Khadijah Ibrahim; Adekunle Akanni Adeleke
This review paper focuses on the use of local additives in water-based drilling mud to reduce environmental impact and improve drilling operations. Drilling mud plays a crucial role in drilling operations by acting as a coolant, carrying drilled particles, stabilizing the wellbore, and preventing wellbore issues. However, poorly formulated drilling mud can lead to drilling difficulties and environmental pollution. Therefore, the exploration of organic-based drilling mud additives, sourced locally in Nigeria, is discussed in this paper.it highlights the potential of transforming organic waste materials, such as rice husk, cassava, corn cobs, and more, into usable products for drilling mud. By utilizing these locally sourced organic materials, the environmental impact of drilling waste can be minimized. The importance of waste management in the oil and gas industry is emphasized, as it is crucial for sustainable drilling practices. The paper further discusses various studies and experiments conducted on the use of local polymers and natural materials as substitutes for imported additives in water-based drilling mud. These materials include cassava starches, agro-waste materials, eco-friendly drilling fluid additives, and various plant-based substances. The performance and effectiveness of these materials are evaluated in terms of viscosity control and fluid loss prevention. The results indicate that many of these local polymers and natural materials can be viable and have shown positive results in terms of improving the rheological and filtration characteristics of the mud, reducing fluid loss, and enhancing overall mud qualities. Earlier studies on the use of agro-waste products as additives in drilling fluids are reviewed in this paper. These studies examine the properties affected by local materials, the type of mud used, and the findings of each study. The economic analysis of using agro-waste materials as drilling additives is also discussed. The conclusion highlights the availability and affordability of agricultural waste materials as potential substitutes for traditional drilling additives, which can help reduce drilling costs. The paper also provides recommendations for future research in this area.
INVESTIGATING THE IMPACT OF ACHI (BRACHYSTEGIA EURYCOMA) ON THE THICKENING TIME OF CEMENT
(NJEAS, 2023-01-01) Ayuba Salihu; Yakubu Nuhu; Khadijah Ibrahim; Abdullahi Gimba; Petrus Nzerem; Ikechukwu Okafor; Oghenerume Ogolo
In recent times, more wells are being drilled and producing in the petroleum industry. To prevent early workover resulting from casing collapse caused by corrosion, shattering of cement sheath during perforation and fracturing, and to protect the integrity of the well, it is important to use properly designed cement slurry with appropriate additives to protect the well from the formation. The development of adequate thickening time cement is a critical task in cementing operations today. Achieving suitable thickening time of oil well cement ensures both prevention of lost circulation and a long wait on cement time. With this in mind, this research work shows a comparative study of the thickening time of oil well cement with achi and without achi contamination under different temperature of 130 ℉, 150 ℉, 200 ℉, and 250℉ and pressure conditions of 1000 psi, 1500 psi, 2000 psi and 3000psi respectively for all the experiment conducted. The thickening time of cement slurry without achi content at 70 Bc were 205, 215, 202 and 200 minutes respectively. The experiment was also conducted under different achi content ranging from 2 g, 4 g, 8 g, 10 g to 12g. The results and analysis were compared. The result with 2g achi content were 164, 147, 146, and 141 minutes. The results with 4g achi content were 127, 131, 130, and 124 minutes. The results with 8g achi content were 71, 69, 75, and 65 minutes, while the results at 10g achi content were 67, 62, 63, and 60 minutes. The results with 12g achi content were 63, 62, 60, and 56 minutes under the temperature and pressure respectively. The data obtained from the experiment signifies that introducing achi and altering the temperature and pressure to the cement slurry has a significant effect on the properties of the cement by accelerating the thickening time.

The Bentonite clay, obtained from Ubakala, Umuahia, in Abia State was investigated as a sorbent for the potential treatment of oil spill in aquatic medium after its modificaion with Dioctadecyl dimethyl ammonium bromide (DODAB). The purified clay sample was subjected to hydrothermal ion exchange reaction to synthesize organoclays under mild reaction conditions. Changes in the microstructural, morphological and physicochemical properties of the modified clay samples were investigated and studied with the use of Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDX). The observations showed the presence of new organic compound groups which indicated that the surfactant was intercalated successfully. The organoclays were further tested in a simulated oil spill situation to assess their potential as oil sorbents and sorbed about 4.5% of the oil that was simulated in the laboratory in water. The results further showed that the synthesized organoclay can be used for the remediation of oil spillage. The organoclays present a cost effective and a suitably environmentally friendly alternative for the remediation of oil spill polluted lands in the Niger Delta region of Nigeria.

(Journal of Renewable Materials, 2023-10-24) Adekunle Akanni Adeleke ; Petrus Nzerem; Ayuba Salihu ; Asmau M. Yahya; Peter Pelumi Ikubanni; Ikechuckwu Okafor; Stephen S. Emmanuel; Adebayo Isaac Olosho; Ademidun A. Adesibikan
Nigeria, often referred to as “the giant of Africa,” boasts a sizable population, a thriving economy, and abundant energy resources. Nevertheless, Nigeria has yet to fully harness its renewable energy potential, despite its enormous capacity in this field. The goal of this review paper is to thoroughly examine the difficulties and untapped opportunities in utilizing biomass for bioenergy production in Nigeria. Notably, Nigeria generates substantial volumes of biomass annually, primarily in the form of agricultural waste, which is often either discarded or burned inefficiently, resulting in significant ecological and environmental damage. Therefore, an efficient approach to reducing pollution and transforming waste into wealth involves converting these biomass resources into energy. This work critically examines the status of biomass utilization for energy applications in Nigeria and highlights the bottlenecks that impede its widespread adoption. The review emphasizes the economic and ecological advantages of biomass utilization over traditional waste treatment methods. Additionally, it underscores the appeal of biomass as an industrial fuel source, particularly considering the current high cost of fossil fuels in contemporary Nigeria. Relevant literature on biomass, energy, agricultural waste, fossil fuel, and calorific value in the context of Nigeria was reviewed by utilizing a thorough search technique in key scientific databases. The analysis did not include any non-English publications. The findings of this research provide valuable insights into the challenges faced in maximizing Nigeria’s biomass potential and offer strategic recommendations to promote the use of biomass for bioenergy development. This review paper will assist a wide range of local and international readers, as well as industries interested in green and bioenergy, in making informed decisions regarding the most suitable types of biomass for biofuel production.

(International Conference on Multidisciplinary Engineering and Applied Science (ICMEAS) Authors:, 2023-11-01) Petrus Nzerem; Oghenerume Ogolo; Blessing O. Alade; Ajiri Otedheke; Ayuba Salihu; Jakada K.
Drilling operations require the use of drilling fluid with optimum characteristics. Desired drilling fluid properties is typically controlled using additives. Due to the environmental and safety impact of synthetic additives, this research investigated the use of degradable food waste namely cowpea skin powder (CSP), sugarcane rind powder (SRP) and yam bark powder (YP) as additives in water-based drilling mud. To check the potential of these biodegradable food waste as additives, their elemental composition and approximate composition were ascertained using Scanning electron microscope with energy dispersive x-ray spectroscopy (SEM EDS) and proximate analysis. The method used included the collection, cleaning, drying and grinding each of the food waste (sugarcane rind, cowpea skin and yam bark) into powdered form of 200 microns, performance evaluation of the additives was done in the concentration of 1% (5grams), 3% (10grams), 4% (15grams) and 5% (20grams) each for each API standard laboratory batch of mud. All three powders were confirmed to have significant fiber, carbon, oxygen and hydrogen content, enough to affect fluid loss and filtration control. Significant effect was observed in pH, Plastic viscosity, Yield point, Gel strength and cake thickness. The organic additives tested had no significant effect on mud density and specific gravity.

Drilling fluids play a variety of roles in order to achieve a smooth and cost-effective drilling operation, the most important of which is their ability to seal permeable walls of the formation through the formation of a desirable mud cake, thereby reducing fluid loss. This study is targeted at evaluating the performance of nano cellulose, cellulose microfibrils synthesised from yam peels as a fluid loss additive and also its effect on the other properties of the drilling mud. The use of nano-cellulose is due to smaller particles forming better impermeable packing that will plug the permeable pore of the mud cake, as well as its ability to hold water. The nano cellulose was synthesised using bleaching, alkali treatment, and acid hydrolysis, and its quality was assessed using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy, which confirmed the removal of some non-cellulose components as well as changes in surface morphology. The results of the experiment revealed that nano cellulose had an effect on the pH, rheological properties, and filtration properties of the drilling mud. The results also show that adding 1.5 g of nanocellulose reduced fluid loss by 8.13 %, and thus it can be concluded that yam peels nanocellulose will be an effective additive at higher concentrations compared to the Carboxyl Methyl Cellulose, a commercial additive.
