Pre-Drill Pore Pressure / Fracture Gradient Analysis
Provides pore pressure and fracture gradient (PPFG) predictions for the planned well(s) based on log data and pressure measurements from two (2) offset wells along with extracted seismic velocity traces at the offset and planned well locations. The geologic structure interpretation provided by the customer will be used to estimate the potential for centroid and buoyancy effects. Daily drilling reports specifying mud weights, rates of penetration, drilling problems, and other experiences will be examined to further calibrate the PPFG predictions. This knowledge will lead to strategies for optimizing drilling performance in the study area and will help in the determination of mud weight requirements.
