Mechanisms of Rheological Deterioration in Spent-Oil-Based Drilling Fluids and Viscosity Reduction Using an Amide-Carboxylic Acid Additive

During drilling operations, the continuous accumulation of low-gravity solids (LGSs) may progressively deteriorate the rheological properties of oil-based drilling fluids (OBDFs), thereby limiting fluid reuse. Centrifugation or dilution provides only limited rheological improvement. To identify the factors contributi...

Data-Driven Prediction of Oil-Based Drilling Fluid Rheology: An Integrated Automated Machine Learning and Shapley Additive Explanations Interpretation Framework

Deep oil and gas resources have become a key strategic frontier for future reserve replacement and production growth. However, the complex downhole conditions in deep formations tend to reduce hole-cleaning efficiency and increase the risk of wellbore instability, making precise regulation of drilling fluid rheology...

High-Temperature-Resistant Long-Term Stable Clay-Free Water-Based Drilling Fluids for Deep Well Drilling and Reservoir Protection

Under high-temperature and high-pressure conditions, drilling fluids with long-term stability and low formation damage are one of the key technologies for ensuring safe and efficient drilling in deep reservoirs and achieving higher oil and gas production. In this study, a zwitterionic polymer (SPG) with high-temperat...
