Unraveling the Scale Effect on Fracture Plugging: A Quantitative Study from Lab-Scale Slots to Field-Scale Fractures via Hydrodynamic Analysis

Abstract Conventional core-scale laboratory fracture-plugging tests may overestimate the ability of granular lost circulation materials (LCMs) to form a complete plugging zone under field-scale conditions. This discrepancy arises because the effects of increasing fracture length...

Preparation andEvaluation of Biopolysaccharide-BasedTemperature-Resistant Drilling Fluid Additives

Abstract Xanthan gum (XG), valued for its environmental friendliness and multifunctionality, has been extensively utilized in drilling fluids. However, its inadequate thermal stability at elevated bottomhole temperatures encountered in deep drilling operations has constrained its...
