Development of High-Performance Water-Based Drilling Fluid using Biodegradable Eco-Friendly Additive (Peanut Shells)


Drilling operation is considered an extremely high-cost business within the petroleum industry. The cost of drilling fluid represents 15–30% of drilling operations. Measurements of all drilling mud properties were conducted in aged and fresh conditions. Furthermore, high pressure and temperature (HTHP) API filtration experiments were executed, as well. The findings were used as a reference comparative point for three concentrations of peanut shell powder (PSP) to comprehend the influence of various concentrations of PSP on the characteristics of spud mud. The findings of this experimental research revealed that the cheap and biodegradable PSP can be exploited as a new multi-role additive to develop filtration and viscosity under surface and sub-surface conditions. Moreover, the study findings demonstrated the suitability of PSP to replace or at minimum substitute traditional and non-degradable chemicals used in the petroleum industry (e.g., lignosulfonate, chrome-lignosulfonate, resinex, etc.). In addition to the benefit of using PSP as a multifunctional additive, it is cheap, easy to prepare, locally available and attainable in large quantities, and friendly to the environment. In summary, PSP has a possibility to be applied in the oilfield as it withstood 79 °C (175 °F) temperature and 30 h of aged time. The application of PSP in the drilling process can mitigate the detrimental impacts of the non-biodegradable conventional chemical materials on personal health safety and the environment in addition to decreasing the overall cost.
