We critically reviewed the technical data associated with this field to assess if resources were sufficient to justify quoted production rates. All aspects of the vendor’s subsurface evaluation were assessed including: data quality, seismic interpretation and the petrophysical, reservoir engineering and resource estimation. We developed independent P50 and P90 (low side) production forecasts for the property. A Field Development Plan review was conducted to confirm reasonableness of technical approach across a range of issues including flow assurance. The Client – a Contractor – had been offered a deal to be paid for installation services in production. The review was designed to confirm that in a worst case sufficient volumes would be available to pay for the installation services; in addition the Client wished to know the key technical risks associated with the project.
