Host-ControlledStepwise CO2 Growth onMaleic Anhydride Revealed by Rotational Spectroscopy

Abstract Gas-phase aggregation of CO2 with organic compounds provides molecular-level benchmarks for understanding how weak interactions guide early cluster growth─a process relevant to CO2 recognition, uptake, and organization in chemically diverse environments. Here, clusters o...

OVT-Domain Azimuthal Traveltime-Constrained AVO Inversion Method

Azimuthal traveltime analysis provides comparatively stable fracture-orientation estimates but limited information on fracture-related elastic changes, whereas amplitude variation with offset (AVO) inversion is sensitive to residual azimuthal moveout. We propose a sequential offs...

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...
