    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.

    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%.
