Expwerimental Study to Analyze the Effect of Calcium Carbonates (CaCO3) and Diesel on KCL/Silicate Mud to Prevent Differential Pipe Sticking (Case Study Dalieb-1)

Abstract

Differential pipe sticking is one of most common problem faced during drilling of oil and gas well. It has a major impact on drilling efficiency and well costs. In this research, the effect of additives on KCL/Silicate mud to prevent differential pipe sticking was identified using mud cake friction factor tester. Calcium Carbonate (CaCO3) and diesel are used as drilling fluid additives. The experimental investigation furnishes that with the proper combination of these additives, the sticking tendency can be reduced significantly with suitable rheological properties and filtration of the drilling fluid required for optimum performance in oil and gas well drilling.
