Project Description
The Barryroe field is located in Licensing Option 08/1 or SEL 2/07, which spans an area of 71,908 acres (291 square kilometers) in the North Celtic Sea basin. Providence operates Barryroe (50%) with partners San Leon Energy (30%) and Lansdowne Oil & Gas (20%).

Barryroe was discovered by Esso in 1973 when well 48/24-1 tested oil from Middle Wealdon sands and flowed at an aggregate rate of 1,300 bopd. A second well, 48/28/1, was also tested and flowed oil from the Middle Wealden sand at a rate of 1,527 barrels per day. A third well, 48/24-3, drilled by Marathon in 1990, tested oil from Lower Wealden sands and flowed at an aggregate rate of 1,619 barrels per day.

A third well, 48/24-3, drilled by Marathon in 1990, tested oil from Lower Wealden sands and flowed at an aggregate rate of 1,619 barrels per day.

The discovery was not deemed commercially viable because of the reservoir's continuity and the high pour point of the oil caused by the high wax content.

When Providence increased its equity in Barryroe in 2010, the operator planned for a new 3D seismic survey to commence over the eastern flank of Barryroe. The survey, completed in July 2011, was used to plan for an appraisal well designed to move Barryroe towards first oil.

In February 2012, the operator confirmed the presence of high-quality light oil within a potential extensive sandstone system at its Barryroe appraisal well. The operator drilled appraisal well 48/24-10z to total depth of 7,550 feet (2,301 meters), encountering a primary basal sandstone reservoir interval within the pre-drill depth prognosis.

The firm said that reservoir development within this sand package is "better than expected" with "very good" correlation of the overall sand packages with the nearby 48/24-3 well. Indications of hydrocarbons were seen while drilling and the subsequent results from wire-line logging have confirmed the presence of 41 feet (12 meters) of net pay (averaging 15 percent porosity and 87 percent hydrocarbon saturation). Pressure data over this interval have revealed the presence of both oil and gas-bearing zones, with the oil gradient being consistent to that of light 40-degree API crude oil.

Providence Seeking Farm-Out Partner for Barryroe
Type: Operator Update

Apr. 2014 - Providence Resources recently confirmed it is in discussions with a number of interested third parties concerning participation in the Barryroe field in the North Celtic Sea offshore Ireland. Barryroe interest holders currently include Providence (80%) serving as operator and Lansdowne Oil & Gas (20%). In an effort to reduce its exposure, Providence is pitching a multiphase development plan that includes an early production phase followed by additional appraisal and development efforts to steadily increase production rates.

Irish Regulator Grants Increase to Areal Extent of Barryroe License
Type: Operator Update

Feb. 2014 - Ireland's Minister of State at the Department of Communications, Energy & Natural Resources granted the Barryroe partners an increase of almost 70 square miles to the areal extent of license SEL 1/11. The Minister of State granted the increase based on the recognition of possible extensions of the Barryroe field to the south and south east. If drilling is able to confirm these extensions, the resource base for Barryroe could be impacted significantly. Providence Resources (80%) and Lansdowne Oil and Gas (20%) are joint venture partners in the license.

Providence Encouraged by Barryroe Development Modeling
Type: Operator Update

Oct. 2012 - Providence Resources recently completed a suite of static and dynamic modeling of the main Basal Wealden oil bearing reservoir interval within the Barryroe complex offshore Ireland. Data from the new models was incorporated with maps made from the recent 3D seismic survey of the area allowing Providence to establish oil recovery factors ranging from 17% to 43%. A modeled recovery factor of 31% over 25 years was achieved based on a development scenario which implemented 41 horizontal production and 22 horizontal water injection wells. Also, the company awarded the Barryroe Concept Development Engineering Study to Procyon Oil and Gas. Procyon will help determine the best development plan for the field based on the different scenarios recently modeled by Providence.

Barryroe is a Huge Find for Providence
Type: Status Update

Jul. 2012 - Providence Resources confirms that estimates of the size of its Barryroe find in the Celtic Sea offshore Ireland have been upgraded. The company reported that its oil in place estimates for Barryroe were now 1,043 million barrels of oil on a P50 basis and up to 1,612 million barrels on a P10 basis. On July 6, oil analysts at Liberum Capital speculated that Barryroe could contain around one billion barrels of oil in place and more than 160 million barrels of recoverable oil. After Providence's announcement, the London-based investment bank upgraded its estimate of recoverable reserves to 200 million barrels. Providence said that after the successful drilling and testing of the Barryroe 48/24-10z well in March, it has now completed a series of comprehensive post-well studies in order to update the in-place volumetric resource estimate for the Barryroe discovery.

Barryroe Discovery Could be Larger than Anticipated
Type: Status Update

Jul. 2012 - Providence Resources might be sitting on more than one billion barrels of oil in place at its Barryroe discovery, according to a research report issued by oil analysts at London-based Liberum Capital. The research note stated that Liberum estimates Barryroe could contain around one billion barrels of oil in place and more than 160 million barrels of recoverable oil based on technical disclosures concerning the Barryroe well made by Providence. These figures are around three times what investors in Providence are expecting from Barryroe, according to Liberum.

Providence Pleased with Barryroe's Core Analysis
Type: Appraisal Operations

Jun. 2012 - Providence Resources has completed the core analysis of the reservoir at its Barryroe discovery. The firm said that permeabilities in the basal oil-bearing reservoir interval have exceeded expectations, while good permeabilities have also been confirmed in secondary logged hydrocarbon-bearing sand. The permeabilities in the basal oil-bearing interval confirm the high-productivity nature of this reservoir as observed during well-testing operations, said Providence. The company will provide a revised resource update for Barryroe later this summer.

Barryroe Proves Production Potential
Type: Status Update

May. 2012 - Providence Resources reported that it is "dealing with a high productivity oil system" at its Barryroe discovery, offshore Ireland in the North Celtic Sea. Providence said that well test analysis at Barryroe indicates a high-permeability basal oil-bearing reservoir interval, while the firm expects horizontal development wells to deliver "significant production rates". Data acquired by Schlumberger during well-testing operations of the 48/24-10z Barryroe well was analyzed to find an average permeability of around 400 millidarcies, confirming high permeability. The analysis forecasts that a 1000-foot (305-meter) horizontal well could deliver around 12,500 barrels of oil per day and 11 million standard cubic feet of gas per day through a standard 4.5-ince outer diameter production tubing under natural lift.

Providence Confirms Significant Reservoir Potential at Barryroe
Type: Appraisal Operations

May. 2012 - Providence Resources has reported that the 48/24-10z appraisal well, the second well to be tested in the basal sands and the sixth well to be drilled at the Barryroe oil discovery, has successfully logged hydrocarbons. In addition to carrying out comprehensive flow testing, significant data acquisition was also carried out utilizing modern wireline equipment. The newly acquired wire-line log data has now been used to evaluate the potential to directly map the hydrocarbon bearing basal reservoir sands, which were successfully tested in the most recent Barryroe 48/24-10z well. This modeling has confirmed that the basal reservoir sandstone package has a defined seismic response which can be detected clearly within the inverted 3D seismic volume. A preliminary review of the inverted 3D seismic volume indicates that the reservoir sequence is widely developed in the Barryroe area. Detailed interpretation of the inverted seismic data has now commenced and will be used to better define the static oil in place estimates for the Barryroe accumulation.

Barryroe Proves to be More than a One-Hit Wonder
Type: Appraisal Operations

Mar. 2012 - Providence Resources has further flow tested the Barryroe discovery offshore southern Ireland. After an additional 17-foot thick net gas-bearing section was perforated to test the potential of the upper part of the sandstone section, highly productive flow rates of 7 MMcf/d and 1,350 bopd were measured. Providence added that a preliminary modeling of the pressure data indicates that a co-mingled flow rate of 17 MMcf/d and 3,350 bopd at a flowing well-head pressure of around 500 pounds per square inch is achievable. Well suspension operations are now complete and the GSF Arctic III (mid-water semisub) rig will now be demobilized to the UK.

Providence Reports Successful Flow Test at Barryroe
Type: Appraisal Operations

Mar. 2012 - Providence Resources has successfully flowed oil and gas at its Barryroe appraisal well, offshore southern Ireland. A 24-foot (7-meter) thick net pay interval in the oil bearing basal Wealden sandstone section was perforated as the first phase of the well testing program. Stabilized flow rates of 3,514 bopd and 2.9 MMcf/d (4,000 boepd) were achieved through a 68/64-inch choke with a well head pressure of 517 pounds per square inch without the use of an artificial lift. Analysis has confirmed that the oil is light with a gravity of 42-degree API and a wax content of 20 percent. The 48/24-10z Barryroe appraisal well is located in around 320 feet (100 meter) water depth, approximately 30 miles (50 kilometers) offshore Ireland at the Standard Exploration License (SEL) 1/11 in the North Celtic Sea Basin.

Providence Resources Hits High-Quality Light Oil in Barryroe
Type: Appraisal Operations

Feb. 2012 - Providence Resources has confirmed the presence of high-quality light oil within a potential extensive sandstone system at its Barryroe appraisal well in the North Celtic Sea, offshore Ireland. The operator drilled appraisal well 48/24-10z to total depth of 7,550 feet (2,301 meters), encountering a primary basal sandstone reservoir interval within the pre-drill depth prognosis. The firm said that reservoir development within this sand package is "better than expected" with "very good" correlation of the overall sand packages with the nearby 48/24-3 well. Indications of hydrocarbons were seen while drilling and the subsequent results from wire-line logging have confirmed the presence of 41 feet (12 meters) of net pay (averaging 15 percent porosity and 87 percent hydrocarbon saturation). Pressure data over this interval have revealed the presence of both oil and gas-bearing zones, with the oil gradient being consistent to that of light 40-degree API crude oil, said Providence. The operator will now perform a well-flow test, which should take 10 days to complete.

Providence Encounters Hydrocarbons at Barryroe Appraisal Well
Type: Appraisal Operations

Feb. 2012 - Providence Resources announced that the Barryroe appraisal well has encountered hydrocarbon shows in its secondary objective. The original drilling timeline was initially set back by weather and later by rig performance issues which significantly delayed the drilling of the 12.25-inch section. Drilling of this section recommenced on Feb. 2, when the necessary rig repairs and maintenance programs were completed by the rig owner. Hydrocarbon shows were encountered during the drilling of the 12.25-inch section, which contains a number of potential secondary reservoir units. Preliminary real time LWD data demonstrates excellent sandstone package correlation with the nearby 48/24-3 well. The forward program includes a comprehensive wire-line data acquisition program of this drilled 12.25-inch section, utilizing modern 'state of the art' down-hole tools, after which the section will be cased. Subsequent operations will include coring of the underlying primary reservoir zone, which is the main focus of this drilling program. Following this, the operator plans to perform drill stem testing of the primary basal sands target in order to ascertain flow rates and productivity. The 48/24-10z Barryroe appraisal well is located in approximately 328 feet (100 meters) of water, around 31 miles (50 kilometers) offshore Ireland in Standard Exploration License (SEL) 1/11 in the North Celtic Sea Basin.

Providence Encounters Notable Gas Shows in Barryroe
Type: Appraisal Operations

Dec. 2011 - Providence Resources announced that well 48/24-10 has encountered notable gas shows in the PSE Seven Heads Limited operated gas reservoir, which overlies the Barryroe oil discovery. The well has reached section total depth of 4,038 feet (1,231 meters) true vertical depth subsea, with the key geological horizons encountered close to the pre-drill depth prognosis. Following casing of this section, the well will be drilled through the underlying primary and secondary Barryroe oil reservoir targets to a TD of 7,464 feet (2,275 meters) TVDSS.┬áThe GSF Artctic III semisub is drilling the well. Barryroe is located in 328 feet (100 meters) of water about 31 miles (50 kilometers) offshore Ireland in Standard Exploration License (SEL) 1/11. Providence operates the license with a 50 percent interest.
