Synthesis and Performance Evaluation of SF-4 Spacer Fluid for Open-Hole Completion with Oil-Based Drilling Fluid in the East China Sea

As oil and gas exploration and development in the East China Sea advance toward deeper and hotter formations, direct contact between oil-based drilling fluid and water-based completion fluid can cause severe rheological incompatibility during open-hole completion. This study developed an amphiphilic SF-4 spacer based o...

Construction of an Extended-Reach Well Torque Prediction Model Based on Multi-Source Drilling Data Fusion and Analysis of Dominant Factors

Extended-reach wells contain long, highly inclined intervals in which drill-string/wellbore contact and cumulative friction evolve continuously with depth, making torque prediction strongly nonstationary. This study develops a multi-source torque-prediction framework using 5977 field samples from a deepwater extended-r...
