3D pore pressure used to optimize well design

08/04/2008
Pore pressure greatly affects drilling safety and the economics of drilling design and well construction.This article focuses on how a calibrated 3D pore-pressure volume can be used to optimize well design when pore pressure and mud weight windows are the dominant issues in drilling.Engineers often use estimated pore and fracture pressure profiles along the well path as primary input to the well design due to their overriding influence on casing seat selection. This, in turn, is the primary driver for hole geometry, casing program, and overall well cost. While this type of workflow has been used historically for wells in abnormally pressured areas, it also applies to wells drilled through...
