EnCore Repeats Success with Additional Cladhan Pay
Tuesday, April 12, 2011
EnCore Oil plc
EnCore provided an update on the Cladhan appraisal well 210/30a-4 located in UK North Sea Block 210/30a.
The appraisal well was drilled as a deviated well to a Total Measured Depth of 12,252 feet and encountered oil bearing Upper Jurassic sandstones in two separate reservoir intervals. No Oil Water Contact was observed. The Upper reservoir sequence had a gross True Vertical Thickness (TVT) of 18 feet and a net sand of 13 feet TVT. The sand has an average porosity of 16 percent. and hydrocarbon saturation of 82 percent. Pressures suggest that this reservoir is in a separate pressure regime from the Lower reservoir. In the Lower reservoir sequence, the main reservoir in previous Cladhan wells, the well encountered a gross TVT of 256 feet and a net sand of 21 feet TVT. The sand has an average porosity of 16 percent. and hydrocarbon saturation of 75 percent. Initial pressure data indicates that the lower sand is in pressure communication with, and is part of the original Cladhan discovery. The well has proven an Oil Down To of 10,447 feet True Vertical Depth Sub Sea (TVDSS), giving a minimum hydrocarbon column of over 1,200 feet.
Upon completion of operations at well 210/30a-4, the Transocean Prospect semi-submersible rig will commence the first planned side-track, 210/30a-4z to evaluate the Upper Jurassic sandstones significantly down dip from the 210/30a-4 well in an attempt to define oil water contacts for both the upper and lower reservoir units, as well as investigating the potential for thickening of the upper unit. It is expected that this side-track will take approximately 20 - 25 days subject to weather or operational delays.
Commenting on the latest well result, Graham Doré, EnCore's Exploration Director said, "This is an important result for Cladhan. The well has confirmed both the presence of a large oil column in the main Cladhan reservoir as well as a new hydrocarbon bearing reservoir sequence, and has yet to find an Oil Water Contact. The next side-track to the east will evaluate the fan structure some 1,000 feet deeper, and has the potential to encounter improved net to gross as well as establishing Oil Water Contacts for both reservoir sequences. This will be followed by a side-track to the south which is designed to confirm the presence of oil in the Central channel."
The equity in the Cladhan joint venture partnership is as follows: EnCore Oil plc (16.6 percent.), Sterling Resources Ltd (39.9 percent., Operator), Wintershall (UK North Sea) Limited (33.5 percent.) and Dyas (10 percent.).
Graham Doré B.Sc. (Hons.) in Geology and M.Sc. in Petroleum Geology and EnCore's Exploration Director, who has over 25 years' experience in the oil exploration and production industry, has reviewed and approved the technical information contained in this announcement.

Ophir to Take Reins of Block Offshore Tanzania
Ophir to Take Reins of Block Offshore Tanzania
Thursday, April 07, 2011
The East Pande license lies in the coastal region of southern Tanzania covering an offshore and onshore area in excess of 7,500km2. The block lies immediately to the west of Blocks 1, 3 and 4 in which Ophir has a 40% interest. Ophir has recently drilled the first deepwater wells offshore Tanzania resulting in three significant gas discoveries. The maximum water depth in the East Pande block is approximately 2,000m. The PSA was awarded to RAKGas in 2006.
In late 2010 RAKGas acquired approximately 1,800 line kilometers of 2D seismic data in the offshore section of the block. The data indicates the continuous nature of the geology between East Pande and the prospective Ophir acreage to the east. Subject to partner and Government consent, Ophir intends to acquire a new 3D seismic survey in the offshore section of the block.
Under the terms of the farm in agreement, Ophir will fund 100% of the cost of the 3D seismic survey and will reimburse certain back-costs. In the event that Ophir elects to drill, RAKGas will be carried through the drilling of the first exploration well.
Ophir and RAKGas are also partners in the Berbera PSA in Somaliland.
Ophir's New Business Director Jonathan Taylor commented, "We are delighted to extend our partnership with RAKGas to the East Pande project and to further deepen our relationship with the Government of Tanzania. With our recent exploration discoveries in Blocks 1 and 4, immediately adjacent to East Pande, we are well placed to build on this success and undertake a fast-track exploration campaign to pursue the petroleum potential of this exciting project."

Breitling O&G Corp.
Breitling has spud the Breitling-Magnolia #2, the second of two wells in its Breitling-Magnolia prospect in Pottawatomie County, Oklahoma. The first well, the Magnolia #1, encountered multiple potential pay zones on its way down to its 4,500 feet. The primary objectives of the Magnolia #2 are the Wilcox Sand at 4500', the Simpson Sands at 4400' and the Hunton at 4175'. A secondary objective includes the Earlsboro Sand at 3625'.
The proposed Magnolia #2 well is located within a 240-acre closure mapped at the Simpson and Wilcox Sands and the Hunton Sand at above an estimated total vertical depth of 4,500 feet.
"If this Magnolia #2 trends like the Magnolia #1 we will have another great well here," said Joe Simo, Chief Geologist for Breitling Oil and Gas.
Management anticipates the well will reach total depth in about 7 days. Well completion and testing on the Magnolia #2 well should begin during the first week of April 2011.
Breitling Oil and Gas CEO Chris Faulkner stated, "Most of the geology on Magnolia #2 mimics what we anticipated and now have confirmed after drilling and logging the Magnolia #1." Faulkner added, "Based on the very positive logs on the Magnolia #1 we expect Magnolia #2 to be a producer as well."
Breitling has current oil and gas exploration projects all over the United States.

FAR
FAR announced that Detailed Agreements have now been finalized with Ophir confirming the terms of an earlier Heads of Agreement to participate in the drilling of the Kora Prospect via the acquisition of a 10 percent paying interest (8.8% beneficial interest) in the AGC Profond PSC, offshore Senegal and Guinea Bissau. Regulatory approval has been granted by the AGC Joint Authority. The agreements also allow Ophir the right to acquire a 22.5% beneficial interest in FAR's Senegal licences.
The Kora well is targeting a prospect having mean prospective oil resources of 448 million barrels (100% basis, Rocksource estimate). The well will be operated by Ophir using the semi-submersible rig Maersk Deliverer and is expected to spud around 11 April 2011 and take in the order of 24 days. The expected spud date may vary depending upon the timing of release by an existing contractor in Ghana from where the rig will mobilize to the AGC area.
The well location is 285km south west of the port of Dakar in a water depth of 2651m. The planned minimum Total Depth for the Kora well is 4,251mSS (approx. 1,600m below the mudline) although consideration will be given to drilling deeper based on the geology encountered.

Exillion Discovers Oil in West Siberia
Exillion Discovers Oil in West Siberia
EWS I - 38 well which was spudded on 2 March 2011 was drilled in 17 days on an eastern part of the East EWS I field on a turn-key contract for a total consideration of 0.8 million.
The well encountered the Jurassic P reservoir at 1,858m which is 2m higher than previously thought. Results of wire line logging combined with oil shows and sample analysis whilst drilling, have confirmed the presence of at least 9m of net oil pay within the Jurassic. Testing of the well will be completed mid-April.
The well was drilled directionally 1.1km to the north-east from the existing well pad. On completion of testing the well will be connected up to existing production facilities. The well is a result of the continued application of 3D seismic combined with a thorough understanding of reservoir geology.
EWS I - 1
Exploration well EWS I -1 is located on the southern part of the EWS I field. The well was originally drilled in 1971, and was subsequently suspended due to the absence of production infrastructure.
In March 2011, after re-interpreting the well logs, the Group saw that wire line logging indicates the presence of 7.2 m of net oil pay within the Jurassic P reservoir, which represents more than a three fold increase from the previous estimate. The Group perforated additional intervals and the well flowed water-free oil naturally to the surface with a flow rate of 530 bbl/day on a restricted 8 mm choke.
