Building A Geological-Pressure Model Incorporating Global Analogues

Written by: Sam Green and Alex Edwards

There are many different elements to a play that require analogues to aid in de-risking, especially in areas with limited offset well data. Analogues are often focused on a similar basin-scale tectonostratigraphic framework, but there are many aspects to a geological-pressure model that must be de-risked, for example, sand-shale geometries, reservoir plumbing, TOC within shales, thermal evolution, and sedimentation rate. There are many examples of analogous processes and relationships that can de-risk the pore pressure from settings that wouldn’t be considered
analogous if solely based on the basin-scale framework.
