Statoil to Commence Drilling Campaign in Barents Sea
May 14, 2012 – Statoil and partners have established a plan to advance exploration drilling in the Skrugard area. The exploration campaign will comprise four new prospects and is scheduled to commence in late 2012. The objective of the drilling campaign is to follow up on the Skrugard and Havis discoveries and to test further upside potential of the area. The four prospects will be drilled back-to-back with the West Hercules (UDW semisub) drilling rig, which will be winterized to meet the weather conditions in the Barents Sea. The drilling campaign will start in PL532 with the Nunatak prospect due to be spud in December this year. Then the rig will proceed to the Skavl prospect located in the same license, and thereafter to the Iskrystall prospect in the neighboring licence PL608. The fourth prospect to be drilled will be announced at a later stage.
Premier Spuds Carnaby Prospect
May 14, 2012 – Premier commenced drilling at the Carnaby exploration well 28/9-5 in the North Sea. The well is being drilled by the Sedco 711 (mid-water semisub) and is being managed by Applied Drilling Technology International. Drilling operations are expected to take about 25 days.

Providence Confirms Significant Reservoir Potential at Barryroe
May 11, 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.

Eni Scores Big in Coral-1 Discovery
May 16, 2012 – Eni has made a “giant” natural gas discovery in Area 4, offshore Mozambique, at the Coral-1 well. The Coral discovery is estimated to contain between 7 and 10 Tcf of gas in place, exclusively located in Area 4. With these new results at Coral-1, Eni estimates that the resources range between 15 and 20 Tcf of gas in place. The new discovery further increases the total potential of the Mamba complex, which holds between 47 and 52 Tcf of gas in place, according to recent estimates. The discovery well encountered a total of 246 feet (75 meters) of gas pay in single high-quality Eocene sand. This discovery is particularly significant since it confirms a new exploration play, which is independent of those drilled so far in previous Mamba wells. Eni will run a production test on the Coral-1 discovery.
Project Details: Coral (ENI)
BG Makes Mzia Discovery
May 16, 2012 – BG Group has made a gas discovery in the Mzia-1 exploration well in Block 1 offshore southern Tanzania. Mzia-1 is the company’s first discovery within the deeper Cretaceous section and opens an extensive new play fairway within Blocks 1, 3 and 4, to complement the now proven Tertiary fairway. Preliminary evaluation of the results indicates 180 feet (55 meters) of natural gas pay in good quality sands. An extensive logging program has been completed, including the acquisition of pressure data and gas samples. The well has de-risked a number of adjacent Cretaceous prospects, which could form part of a future Mzia hub, stated the operator. These prospects are expected to be tested in a future appraisal program to be defined following incorporation of data from this new well and 3D seismic. The new resources proven by Mzia and the potential of adjacent prospects are currently under evaluation.

Tap Oil Updates Ops in Accra Contract Area
May 16, 2012 – The Ministry of Energy, Ghana has granted Tap Oil Limited a 12-month extension of the Initial Exploration Period under the Petroleum Agreement in respect of the offshore Accra Contract area. The IEP now ends on Sept. 23, 2013, by which the commitment well must be drilled. New 3D seismic was acquired over the deepwater part of the Contract Area in early 2011. Interpretation of the data at hand indicates multiple large prospects within both the post-rift Upper Cretaceous fan sands (the same play type as Jubilee) and pre-rift Lower Cretaceous rotated fault blocks (the same play type as the Espoir and Baobab oil fields). To date several prospects and leads have been mapped and have unrisked prospective resources of greater than 3 billion barrels. It is anticipated that the commitment well will likely target a large, deepwater, Jubilee look-a-like trap with prospective resources in the range of half a billion barrels. Well planning is in progress with various rig options currently being investigated.
