DUBLIN, Ireland – CGG’s SR/V Vantage vessel has completed acquisition of 500 sq km (193 sq mi) of 3D seismic data over the Deep Kinsale prospect in the Celtic Sea offshore southern Ireland.
According to technical operator Fastnet Oil & Gas, a second seismic vessel,SR/V Angler, was brought in for undershoot operations.
An unrelated independent report by SLR Consulting estimates combined oil volumes for the four Deep Kinsale reservoirs at potentially up to 2.365 Bbbl. TheDeep Kinsale structure covers an area of up to 162 sq km (62 sq mi).
Once the new 3D data has been processed and interpreted, the results should help narrow down the in-place resources range; identify potential for structural compartmentalization by faulting; and, through use of seismic attributes analysis, define potential reservoir sweet spots.
Fastnet will combine this information with a new analysis of the active petroleum systems around and under the producing Kinsale Head gas field, focusing on hydrocarbon charging mechanisms and the potential for re-migration during Tertiary basin uplift.
This should help efforts to identify a target area for a well planned by 2015.
Another focus for the company will be an independent pilot development study to address development risk associated with the geological characteristics of theBasal Wealden Oil Sand. Fastnet believes a phased development is the best way to manage the risk.
