Allen Emmanuel Depasucat, Eldon C. Dineros, Franz Jan Legal, Gene Patrick M. Santos, and Michael Jeff Tabile successfully defended their thesis proposal entitled "Corn Husk (Zea mays) Powder as a Lost-Circulation Material (LCM) for Seepage Control in Water-based Drilling Mud" last January 7, 2023, in partial fulfillment of their Petroleum Engineering Methods of Research.
One of the most serious issues encountered when drilling oil wells is lost circulation. When the overall pressure exerted against the formation at any depth reaches the breakdown pressure, circulation is lost. Lost circulation costs money by wasting materials, rig time, and other resources. It has been established that lost circulation happens during drilling in around 20%-25% of wells drilled globally, and that lost circulation can result to a blowout. Since environmental preservation has been the major issue prior to hydrocarbon exploration, selecting muds and their additives becomes a complicated issue.
Here, the researchers will use corn husk powder (CHP) derived from waste corn husks as a lost-circulation material. The CHP will be characterized using TG-DTA and FTIR. A series of experiments will be conducted to investigate the influence of additive composition on drilling fluid parameters. The pH value, mud density, apparent viscosity, plastic viscosity, yield point, gel strength, fluid loss, mud cake thickness, and lost circulation behavior for each formulation will be evaluated. Ultimately, this research will benefit the environment by adopting environmentally friendly alternatives to lost-circulation materials.
Their research project will be conducted from 2023 to 2024.
