Starfish-1 Well Drilling Ops Move Forward (Ghana)
Rialto Energy Limited has released an update on the Ophir Energy-operated Starfish-1 oil exploration well in the Offshore Accra Contract Area, Ghana.
During the period from 1400 hours (AWST) on 25 June 2013 to 1400 hours (AWST) on 2 July 2013 the 17½” (444.5mm) hole section was drilled to final total depth. The 13⅜” (340mm) casing was run and set at 3,035 metres and the well drilled ahead in the 12¼” (311mm) hole section to 3,695 metres.
The forward plan is to drill ahead in 12¼” (311mm) hole to final total depth.
The Contract Area is now covered by quality 3D seismic data. In the event of a discovery at Starfish-1 confirming a significant petroleum system, there are a number of other leads and prospects identified on the block that would be of interest.
The well, being drilled as a vertical well in a water depth of 1,500 metres, should take a total of 35 days (trouble free) to drill to a proposed total depth of 4,560 metres.
The Starfish prospect is located in the Offshore Accra Contract Area in offshore Ghana along the prolific offshore West African Margin. The Starfish prospect was matured following reprocessing of the original 3D seismic data and the acquisition of the new 3D survey in 2011 over the outboard deep water area.
