Pre-Drill Planning
Prepare geological programmes, including responsibility for the Ineos Well Proposal Document (WPD) which is the formal description of the geological target used by the drilling department for the detailed well design. This includes well objectives, stratigraphic prognosis (including faults), overburden and reservoir pore pressure prediction, data acquisition programmes and geological uncertainties and drilling hazard assessments. Data is provided by the project geologist and petrophysicist.
Review offset data and identify geological risks. Coordinate with project geophysicist to identify fault risks and location of Permian Zechstein salts that may pose a drilling risk.
Coordinate with drilling engineers and subsurface teams to align well objectives. Supporting the preparation and review of the detailed drilling programme.
