Well Control - Well Design
This article descrobes the drilling program and other Well Design considerations for Well Control
1 Drilling programme
The drilling programme is based on the information provided by the subsurface department and in summarized in the Well Planning Datasheet. It should include in particular:
A statement on shallow gas.
Formation characteristics:
- permeability, fluid type, hydrocarbon depths, gas zones, etc.;
- formation pore pressure gradient profile;
- expected formation strength gradient at the proposed casing setting depths and the requirement of formation integrity tests (limit- or . . .
