Providence indicates today that the Kylemore prospect located 20 kilometres (12 miles) south-west of Corrib could contain up to 226 billion cubic feet of gas in place, while the Shannon structure, 10 km (6.2 miles) south-west of Corrib could be bigger than the 1 trillion cubic foot Corrib field.
Details of the two gas prospects were published today by Providence after the company completed an initial technical analysis of its 11/12 Licensing Option in the Slyne Basin, which was awarded to Providence and First Oil Expro in Ireland's Atlantic Margin Licensing Round last year.
Based on 2D and 3D seismic data, Kylemore has been interpreted as a four-way dip closed anticlinal structure and recent mapping suggests it is directly analogous to the Corrib field. “Volumetric analysis based on available Kylemore prospect maps indicates a potential gas in place of up to c. 228 BSCF [billion standard cubic feet],” Providence stated today.
And the Shannon prospect, which was drilled by Enterprise Oil with the 18/25-2 exploration well in 1999, without encountering the Corrib reservoir, was originally thought to be faulted. Providence points out that Enterprise interpreted Shannon as having a structural closure encompassing 23 square kilometres, whereas the 1 tcf Corrib field has a 15 sq. km structural closure. “The LO 11/12 partners believe that Shannon warrants a complete re-evaluation in the context of any remaining resource potential,” Providence says.
And the company's technical director John O'Sullivan, says the company plans to apply modern seismic processing technologies to available 3D seismic data to quantify the resource potential of the area. “This is Providence's first licence authorisation in the area and we are delighted to be working on the project with First Oil, the largest UK privately owned North Sea oil & gas producer.”
Providence operates the 11/12 LO with 66% and First Oil Expro holds 33%.
