Afren Confirms High Quality Oil at Okoro East
Mar 7, 2012 – Afren has completed testing at the Okoro East oil discovery, confirming high-quality API oil of 38 to 40 degrees in excellent reservoir sands. Based on the test data the company expects future horizontal production wells at Okoro East to be capable of yielding between 4,500 to 7,000 bopd per well. The company will drill two production wells using existing facilities in the second half of 2012 and up to eight production wells, under a full field development scenario. Three drill stem tests have been performed and completed, said Afren. The purpose of this test was to obtain fluid samples and pressure data in order to establish reservoir connectivity, heterogeneity and quantify permeability and porosity. The tests have confirmed a high quality 38- to 40-degree API oil, multi-Darcy permeabilities and an average porosity of between 30 percent to 35 percent in the subject reservoirs. The pressure data obtained has helped with the company’s structural understanding of the field and supports the pre-drill volumetric estimates (Pmean STOIIP of 157 million barrels). Based on the test data, the company expects future horizontal production wells at Okoro East to be capable of yielding rates between 4,500 bopd to 7,000 bopd per well. The company intends to drill up to two production wells in 2H 2012 using the free well head slots on the existing Okoro platform, which will be tied-back to the Armada Perkasa FPSO. This production information will allow Amni and Afren to finalize development options with up to eight possible production wells under a full field development.

Faroe Petroleum Completes Drilling Ops at T-Rex, Bolan
Mar 7, 2012 – Faroe Petroleum has discovered oil in both the T-Rex and Bolan exploration prospects in the Norwegian sector of the North Sea, but not in commercial quantities. The 6406/3-9 well, reached a total depth of 13,725 feet (4,183 meters) within shales of the Lange Formation. The well targeted Lower Cretaceous sandstones of the Lange formation (T-Rex) and Lysing formation (Bolan). T-Rex was the primary target and preliminary results based on extensive coring, wireline logs and pressure data have confirmed the presence of oil, but in a thinner than expected reservoir interval, and the well will therefore not be production tested. Fluid samples were successfully recovered in T-Rex. The quality of the oil was in line with fluids seen in the original discovery well 6506/11-2 (drilled by Statoil in 1991). The Bolan prospect in the shallower Lysing formation also encountered an oil column within an inter-bedded sandstone package. A similar extensive data gathering program was performed on the Bolan prospect as with T-Rex. Additional evaluation is required in order to delineate the areal extent of the oil bearing layers, before any decisions in terms of a further appraisal program can be made.

Statoil Touts Success at Skrugard Appraisal
Mar 6, 2012 – Statoil is in the process of concluding the drilling of appraisal well 7220/5-1 on the 7220/8-1 (Skrugard) gas/oil discovery. The discovery was proven in 2011 in Middle and Lower Jurassic reservoir rocks. The objectives of the appraisal well were to confirm the previous volume estimate for the Skrugard discovery and to collect reservoir and overburden data for field development planning. Both objectives have been met, said Statoil. Drilled by Transocean Barents (DW semisub), appraisal well 7220/5-1 has proven a gas column of 85 feet (26 meters) overlaying an oil column of about 158 feet (48 meters). Both column heights and reservoir properties came in as expected. This confirms the previous volume estimate for the Skrugard discovery and the total resource estimate for the Skrugard and Havis structures ranging from 400 to 600 million barrels of recoverable oil. Statoil is currently considering several alternative development concepts for the discovery.
