An experimental study to evaluate the use of oil to prevent differential stuck pipe in Nahr Umr oil field
Differential pipe sticking (DSP) is a main challenge when using water-based drilling fluids developed with bentonite clay.This study employed a Fann VG meter, a self-fabricated tester, and a stickance tester to examine the effect of oil on water-based drilling mud (WBM) and to control this issue.The study found that oil is more suitable than WBM fo
