Evaluation of Moderate Collapse Characteristics and Optimization of Drilling Fluid Density for Horizontal Wells in Deepwater Gas Fields

Conventional drilling fluid density design based on the onset of yielding may not adequately balance wellbore stability against the available mud-weight window in deepwater sandstone–mudstone interbeds, where collapse and lost-circulation risks coexist. Using three-pressure profiles, actual mud weights, and operational...
