DUBLIN, Ireland – Providence Resources has updated its Barryroe oil discovery technical assessment. Barryroe is offshore southern Ireland in 100 m (328 ft) water depth in the North Celtic Sea basin, around 50 km (31 mi) offshore.
Earlier this year, Providence successfully flow tested oil and gas from the48/24-10z appraisal well. This was the sixth well on Barryroe, and the second to test the basal sands. All wells to date have logged hydrocarbons.
The aim of the latest well was to capture comprehensive data and combine this with results from the five previous wells, the last of which was drilled in 1990, and 3D data from the 2011 seismic program.
US-based processing group Geokinetics has evaluated the seismic response of the main basal hydrocarbon-bearing reservoir interval. Its modeling confirms that the basal reservoir sandstone package has a defined seismic response which can be detected clearly within the inverted 3D seismic volume.
Analysis indicates that the reservoir sequence is widely developed in the Barryroe area. Detailed interpretation of the inverted seismic data is under way and will be used to better define static oil in place estimates. Results are expected this summer.
John O’Sullivan, technical director of Providence said: “The results of the most recent seismic modeling and inversion are exceptionally encouraging as they confirm our ability to seismically image the Barryroe basal sandstone package, which tested at such great rates in the recent well. This materially helps in the mapping of the Barryroe license area.
“The preliminary work also confirms that the reservoir is widely developed, which is very positive both in terms of incremental resource potential as well as our ability to accurately assess its distribution.”
