Providence Resources l c : TECHNICAL UPDATE - NEWGRANGE PROSPECT, GOBAN SPUR BASIN, OFFSHORE IRELAND

 New 2D seismic data confirm the presence of the large Newgrange Cretaceous four-way dip closure

 Marked improvement in both structural and stratigraphic imaging over previous 2D

 Seismic velocity analysis indicates significant porosity preservation within the

 Possible overburden shallow gas effects potentially supports hydrocarbon migration into licence area

Providence has recently completed an initial evaluation of its licensed data from the newly acquired southern Porcupine Polarcus multi-client 2D regional seismic reflection survey. This initial work has been focused on the interpretation and mapping of the key Top Cretaceous reflection on the new long offset seismic profiles. This work has confirmed the previous interpretation that the Newgrange prospect comprises a significant c. 1000 km2 four way dip closed structure. The crest of the Newgrange structure lies just c. 500 m BML and has a total structural elevation of c. 400 m. Current overburden fracture gradient analysis based on offset well data indicates a gas column top-seal capacity of up to c.
300 m. Both structural as well as stratigraphic imaging within the Newgrange prospect have been significantly improved with detailed carbonate seismic facies mapping now possible within the Cretaceous objective.
The Newgrange prospect reservoir interval demonstrates low seismic velocities (c. 3,000 metres/sec) versus those seen in the offset 62/7-1 well, which encountered a c. 950 m gross section of predominantly porous Cretaceous carbonates. These velocities would indicate porosities in excess of c.
30% at the Newgrange prospect. Notable also are interpreted shallow gas effects in the Cenozoic
overburden on the northwest flank of the prospect, which may provide evidence of hydrocarbon migration into the Newgrange licence. Further work on the Newgrange prospect is ongoing together with an evaluation of the underlying stacked Jurassic potential.
Speaking today, John O'Sullivan, Technical Director of Providence said:
"Similar to the giant Kinsale Head Gas Field off the south coast of Ireland, our Newgrange prospect also comprises a shallowly buried Cretaceous four way dip-closure. The Newgrange structure is however areally far more significant, being about ten times that of Kinsale Head whilst also enjoying a higher pressure regime due to its deeper water location. The offset 62/7-1 well has demonstrated the potential for massive Cretaceous carbonate development locally and the new seismic velocity data signal excellent porosity preservation at Newgrange. We view hydrocarbon source rock adequacy and access as the key risks at Newgrange, however, the new evidence for potential shallow gas is encouraging. Whilst further studies are ongoing, we believe that the combination of material and high density prospective resources with low exploration drilling costs should serve to promote Newgrange as a very attractive deep-water exploration proposition from a risk-reward perspective."
