OPC undertook a review of existing PTA (Pressure Transient Analysis) data and existing laboratory PVT analyses from several wells in an offshore field in West Africa.
The field comprises vertically stacked reservoir Units and initial analysis by the operator had identified the potential existence of primary gas caps. Expert staff from OPC reviewed both the PVT and PTA data in detail and, thanks to their experience in working on similarly structured reservoirs, were able to provide an accurate assessment of the existence of gas caps for the asset owner.
