Equity Determination

Geophysical expertise for equity redetermination

I contribute geophysical analysis and technical review to equity determination and redetermination teams. My experience includes projects in the UK and Norwegian North Sea and offshore Canada.

These assignments bring together several subsurface disciplines and require careful examination of the data, interpretations and assumptions used to assess participation. My role is the geophysical contribution, supported by detailed analysis and formal technical reporting.

Discuss geophysical support for an equity project. Related expertise includes quantitative interpretation and reservoir characterisation.
