TECHNICAL UPDATE
DROMBEG PROSPECT
SOUTHERN PORCUPINE BASIN
Providence Resources P.l.c., ('Providence') the Irish oil and gas exploration and production company, whose shares are quoted in London (AIM) and Dublin (ESM), is pleased to provide a technical update on a major new 3D seismic programme, which is planned to be acquired by Polarcus, subject to statutory assessment, in the southern Porcupine Basin, offshore south-west Ireland. This non-exclusive multi-client survey, which is planned to commence this summer, will cover the deep-water Drombeg exploration prospect that is located in Frontier Exploration Licence (FEL) 2/14 ('Drombeg Licence'). The Drombeg Licence, which is situated in c. 2,500 m water depth and c. 220 km off the west coast of Ireland is operated by Providence Resources (80%) on behalf of its partner Sosina Exploration Limited (20%). Providence and Sosina recently converted Licensing Option (LO) 11/9 into FEL 2/14 (see RNS of 20th January 2014).
The total planned seismic acquisition programme will cover a minimum area of 3,200 km2, which will include c. 1,065 km2 over the Drombeg Licence. Under the terms of the recently executed agreement, Providence and Sosina have agreed to licence a total of 2,250 km2 of data which will include the area over the Drombeg Licence and adjacent open acreage for a fixed sum. This 3D seismic programme will fulfil the seismic data acquisition work programme obligations for the first phase of FEL 2/14. Polarcus plan to carry out the seismic acquisition programme using one of their high-end "A" class 3D vessels.
Speaking today, John O'Sullivan, Technical Director of Providence said,
"This new survey represents the largest 3D seismic programme to be announced for offshore Ireland so far this year. Providence's involvement has been integral in allowing Polarcus to commit to such an extensive 3D acquisition programme.
"We expect that these new high resolution 3D data over our Drombeg prospect will confirm the potential which has been identified within the Lower Cretaceous section and will allow for the commencement of well planning on Drombeg. These data will also allow us to evaluate the potential in the stacked Jurassic and Paleocene levels where significant addition exploration prospectivity has been identified.
"We are also very pleased to be working with Polarcus again, who successfully acquired 3D seismic surveys on both of our Barryroe and Spanish Point North blocks during 2011."

ABOUT PROVIDENCE
Providence Resources P.l.c. is an Irish based oil & gas exploration and appraisal company with a portfolio of appraisal and exploration assets offshore Ireland and the U.K. The Company is currently leading a circa $500 million multi-year drilling programme on a number of exploration/development wells over 6 different basins offshore Ireland, representing the largest drilling campaign ever carried out offshore Ireland www.providenceresources.com.
ABOUT DROMBEG
The Drombeg prospect lies in c. 2,500 metre water depth and is c. 3,000 metres below the seabed. The prospect is located in the southern Porcupine Basin, c. 220 km off West Cork, being c. 60 km from the ExxonMobil-operated Dunquin exploration prospect which was drilled in mid-2013. In 2012, Providence completed a major seismic inversion programme over the Lower Cretaceous Drombeg prospect, together with an assessment of its associated prospective resource potential. Initial rock physics modeling and seismic inversion work was carried out by Ikon Science over key 2D Drombeg seismic lines, which exhibited a marked seismic anomaly. This initial work modeled the Drombeg anomaly to be consistent with the presence of thick hydrocarbon bearing sandstone intervals.
At that time, the Company also confirmed that a large Jurassic fault block closure, with a pronounced crestal fluid escape feature, had been also identified beneath the Drombeg Lower Cretaceous prospect. Results from the inversion study, together with a volumetric analysis of the Lower Cretaceous interval, has indicated a recoverable P50 prospective resource potential of 872 MMBO, based on an oil in place volume of 2.970 BBO. 3
Two separate stratigraphic, but vertically stacked objectives have also been identified in the overlying Lower Cenozoic and underlying Upper Jurassic. The Lower Cenozoic feature is interpreted to comprise a deep-water basin floor fan covering c. 295 sq km and which exhibits marked amplitude versus offset (AVO) anomaly. The deeper Upper Jurassic feature is mapped as a large tilted fault block structure with c. 140 sq km of closure. A notable fluid escape feature has been interpreted at the crest of the Upper Jurassic tilted fault block and which appears to be acting as a hydrocarbon migration path into both the overlying Drombeg Lower Cretaceous and Lower Cenozoic target intervals. This fluid escape feature is significant in that it suggests an oil remigration model at Drombeg which is similar to that which has been proposed for the BP-operated Foinaven and Schiehallion Fields in the UK West of Shetlands.
