Preparation and High-Temperature Fracture-Sealing Performance of an Oil-Absorbing Swelling Gel for Lost-Circulation Control in Oil-Based Drilling Fluids

Lost circulation in fractured formations remains challenging for oil-based drilling fluids because conventional rigid bridging materials can be sensitive to fracture geometry and form porous seals. In this study, an oil-absorbing swelling gel plugging agent (OSGP) was prepared by water-in-oil emulsion free-radical poly...
