This study focuses on the important role of drilling mud in successful drilling operations, particularly in preventing and treating differential stuck pipes. Differential pipe sticking (DSP) is a common challenge when drilling through a pay zone with water-based drilling mud containing bentonite clay. However, using oil as an additive in a water-based mud (WBM) system offers distinct advantages and can significantly improve drilling performance. The research utilizes the Fann VG meter, a self-fabricated tester, and a tester of stickance to investigate the impact of oil on water-based drilling mud (WBM) and controlling DSP to address this challenge. The empirical study demonstrates that adding oil to the drilling fluid enables it to maintain its rheological properties (PV, YP, and API fluid loss) while reducing filtration loss from 7 to 4.8 cc and friction coefficient from 0.30 to 0.05. This indicates that emulsion mud can mitigate the risks of differential sticking by maintaining the oil concentration within the recommended limit (not exceeding 3%). Balancing the maintenance of rheological properties with the reduction of friction coefficient is essential to reaching optimal drilling performance and preventing differential pipe sticking.
