Wawa-1 exploration well finds oil and gas-condensate

Tullow Oil plc (Tullow) announces that the Wawa-1 exploration well in the Deepwater Tano licence offshore Ghana has intersected oil and gas-condensate in a Turonian turbidite channel system. Wawa-1 encountered 20 metres of gas-condensate pay and 13 metres of oil pay in turbidite sands. Samples show the oil to be good quality between 38 and 44 degrees API. The well was drilled 10 kilometres north of the Enyenra-3A well, testing the previously undrilled, updip portion of the licence. Pressure data shows that it is a separate accumulation from the TEN fields. The well will now be suspended for possible future use in appraisal and development operations. The Atwood Hunter semi submersible rig drilled the Wawa-1 well to a final depth of 3,322 metres in water depths of 587 metres. Tullow (49.95%) operates the Deepwater Tano licence and is partnered by Kosmos Energy (18.00%), Anadarko Petroleum (18.00%), Sabre (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Makore-1 well encounters thick water-bearing sands

Kosmos Energy (NYSE: KOS) announces today that the company's Makore-1 exploration well on the West Cape Three Points Block offshore the Republic of Ghana encountered 37 meters (121 feet) of good-quality Campanian-age water-bearing sandstone reservoirs and 46 meters (151 feet) of good-quality Turonian-age water-bearing sandstone reservoirs. The Makore-1 well was Kosmos' first well in the southeastern portion of the block. The well explored a stratigraphic trap in a Turonian-age fan system. The Makore-1 well is located 25 km (15 miles) southeast of the company's Mahogany-1 exploration well that discovered the Jubilee Field. The "Atwood Hunter" semi-submersible rig drilled the Makore-1 well in a water depth of 1,409 meters (4,623 feet) to a total depth of 3,876 meters (12,716 feet). The "Atwood Hunter" will remain on the block to drill the Akasa-1 exploration well, formerly known as the Dahoma Up-dip prospect. The Akasa-1 well is expected to be spudded shortly. Kosmos is the operator of the West Cape Three Points Block in which the company holds a 30.875% interest. An affiliate of Anadarko Petroleum Corporation has a 30.875% interest; an affiliate of Tullow Oil plc has a 22.896% interest; E.O.

Teak-2 exploration well discovers hydrocarbons offshore Ghana

Tullow Oil plc (Tullow) announces that the Teak-2 exploration well in the West Cape Three Points licence offshore Ghana has discovered 27 metres of net hydrocarbon bearing Campanian and Turonian reservoirs. The well was targeting an undrilled fault block between the Jubilee field and the Teak-1 discovery, located 1.8 km southwest of the recent Teak-1 well and 3.5 km northeast of the Mahogany-2 well. Results of drilling, wireline logs and samples of reservoir fluids confirm that the well has intersected five intervals containing high quality oil, gas and gas-condensate. Six metres of net oil and gas pay were encountered at the top of good quality Campanian reservoirs, over 100 metres thick. Jubilee equivalent Turonian reservoirs contain 21 metres of net hydrocarbon pay, 16 metres of which is rich gas. Static pressure data suggests this potentially forms a gas cap to the Jubilee oil field. Future analyses and pressure interference testing will determine hydrocarbon contacts and the extents of these two adjoining fields. The Atwood Hunter rig drilled Teak-2 to a total depth of 3,409 metres in water depths of 885 metres. On completion of operations, the well will be suspended for future use and the rig will move to drill the Banda-1 well which is targeting Campanian and Cenomanian reservoirs in the east of the licence. Tullow has a 22.896% interest in the West Cape Three Points licence and its partners are Kosmos Energy (Operator) and Anadarko Petroleum Corporation (30.875% each), the E.O.Group (3.5%), Sabre Oil & Gas Holdings Ltd (1.854%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Teak-1 exploration well discovers hydrocarbons offshore Ghana

Tullow Oil plc (Tullow) announces that the Teak-1 exploration well in the West Cape Three Points licence offshore Ghana has discovered approximately 73 metres of net hydrocarbons in two Campanian and three Turonian-aged reservoirs. The well was located 4.6 km northeast of the Mahogany-2 well, 2.7 km outside the Jubilee Unit boundary. In the shallower Campanian-aged reservoirs, the well intersected 6 metres of oil pay in the upper zone and 33 metres of gas pay with an underlying 15 metre 40 degree API oil leg, in the lower zone. In the deeper stratigraphic Turonian-aged reservoirs, the well intersected 14 metres of gas-condensate pay in two separate zones and 5 metres of 32 degree API oil pay in a deeper level. The up-dip combination structural and stratigraphic Campanian trap is potentially 50 sqkm in area and will be the subject of further appraisal activity. Interpretation of the potential extent of each of the deeper Turonian zones is ongoing. The Atwood Hunter rig drilled Teak-1 to a total depth of 3,170 metres in water depths of 868 metres. On completion of operations, the well will be suspended for future use and the rig will move to drill the Teak-2 well which is targeting Campanian and Turonian age reservoirs in a separate fault block between the Teak discovery and the Jubilee field. Tullow has a 22.896% interest in the West Cape Three Points licence and its partners are Kosmos Energy (Operator) and Anadarko Petroleum Corporation (30.875% each), the E.O.Group (3.5%), Sabre Oil & Gas Holdings Ltd (1.854%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Mahogany-5 successfully appraises southeast Jubilee

Tullow Oil plc (Tullow) announces that the Mahogany-5 appraisal well has continued the successful appraisal of the area immediately to the southeast of the Jubilee Field offshore Ghana. The results of drilling, wireline logs and reservoir fluid samples show that the well penetrated a total net oil pay of 23 metres in sandstone reservoirs over a gross interval of 51 metres. Reservoir fluid samples recovered 28-32 degree API oil and pressure data have confirmed reservoir communication with the previously drilled Mahogany-4 well. Mahogany-5 completes the appraisal of the southeast Jubilee area and follows successes at the Mahogany-3, Mahogany-4 and Mahogany Deep-2 wells. Geoscience and engineering studies are continuing to refine the potential resource range and to advance development planning activities for this area. The well was drilled by the Atwood Hunter rig to a total depth of 3,988 metres in a water depth of 1,149 metres. The well is located approximately 62km offshore and about 7km southeast of the Mahogany-1 well, the Jubilee discovery well. The rig will now leave Ghana to work for another operator and will return in the fourth quarter of 2010 on a planned nine-month drilling programme in the West Cape Three Points licence. Tullow has a 22.896% interest in the West Cape Three Points licence which is operated by Kosmos Energy.

Dahoma-1 exploration well results

Tullow Oil plc (Tullow) announces that the Dahoma-1 exploration well in the West Cape Three Points licence encountered water bearing reservoirs. The Dahoma-1 exploration well was drilled 11 kilometres south of Mahogany-3 to explore a down-dip satellite prospect within the southeast Jubilee area, outside of the main Jubilee Unit Area. It intersected 30 metres of good quality sandstone reservoir below a possible oil-water contact and some indications of oil migration point to good potential for oil trapped up-dip. The Atwood Hunter rig drilled Dahoma-1 to a total depth of 4,390 metres in water depths of 1,564 metres and will now move to drill Mahogany-5 to appraise the up-dip oil accumulations eastwards of Mahogany-3. A comprehensive drilling programme is planned for the remainder of 2010 and into 2011 targeting a combination of lower-risk and high-impact exploration and appraisal targets. The next high-impact wildcat is Owo-1, in the Deep Water Tano licence, which will be drilled in June with the Sedco-702 rig targeting the upside potential in the greater Tweneboa fan system. Tullow has a 22.896% interest in the West Cape Three Points licence and its partners are Kosmos Energy (Operator) and a subsidiary of Anadarko Petroleum Corporation, (30.875% each), the E.O. Group (3.5%), Sabre Oil & Gas (1.854%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest). Tullow (49.95%) operates the Deepwater Tano licence and is partnered by Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Tweneboa-2 discovers significant oil and gas-condensate field

Tullow Oil plc (Tullow) announces that the Tweneboa-2 exploratory appraisal well, being drilled some 6 km southeast of the Tweneboa-1 discovery, has intersected a significant combined hydrocarbon column. Results of drilling, wireline logs and samples of reservoir fluids establish that Tweneboa is a major oil and gas-condensate field. The well has encountered a gross reservoir interval of 153 metres containing 32 metres of net hydrocarbon pay in stacked reservoir sandstones, comprising a 17 metre oil bearing zone below a 15 metre gas-condensate bearing zone. A combined hydrocarbon column of at least 350 metres has been established between the lowest known oil in Tweneboa-2 and the top of the gas-condensate at Tweneboa-1, demonstrating this is a highly prospective and extensive turbidite fan system that will be evaluated with additional drilling. Following completion of logging operations the well will be deepened to test further exploration potential beneath the Tweneboa field. The well will then be suspended for future use in appraisal and development. The Atwood Hunter semi-submersible drilled Tweneboa-2 in the Deepwater Tano block to an interim depth of 3,860 metres in water depths of 1,321 metres. On completion of operations on Tweneboa-2, the rig will move to drill an exploration well in the West Cape Three Points block east of the Jubilee field. Tullow (49.95%) operates the Deepwater Tano licence and is partnered by Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Successful appraisal well drilled on the Odum field

Kosmos Energy announces today that the Odum-2 appraisal well confirmed the company's Odum oil discovery made in early 2008 offshore the Republic of Ghana on the West Cape Three Points Block. The results of drilling, wireline logs and reservoir fluid samples show the Odum-2 well penetrated net hydrocarbon-bearing pay of 20 meters (66 feet) in high-quality stacked sandstone reservoirs over a gross interval of 182 meters (597 feet). The well is about 4 kilometers (km) northeast of the Odum-1 well, which is approximately 18 km east of Kosmos' Mahogany-1 exploration well and the Jubilee oil field. Kosmos is operator of the West Cape Three Points Block. The Odum-2 well encountered 20 meters (66 feet) of net oil pay in two intervals that appear to be in static pressure communication with the Odum-1 well. The Odum-2 well encountered an oil-water contact 58 meters (190 feet) below the lowest-known oil in the Odum-1 well, extending the known oil column beyond the deepest oil seen in the Odum-1. Reservoir fluid samples recovered indicate an oil gravity of approximately 18-19 degrees API. The Odum-2 well was drilled by the "Atwood Hunter" semi-submersible rig to a total depth of 2,506 meters (8,222 feet) in a water depth of 816 meters (2,677 feet). "We are pleased that we have successfully confirmed the second of our four oil and gas discoveries to date offshore Ghana," said Brian F. Maxted, Kosmos Chief Operating Officer. "The Odum-2 well validates the upside potential of the Campanian play on the West Cape Three Points Block, which has been determined to be separate from the Jubilee Field play. We will continue to evaluate the well's results." Kosmos has drilled nine consecutive successful exploration and appraisal wells offshore Ghana for a 100 percent success rate in the region. Following the drilling of the Odum-2 well, the "Atwood Hunter" will be moved to the adjacent Deepwater Tano Block where it will drill the Tweneboa-2 appraisal well that will evaluate the most recent oil find made by Kosmos and its block partners in the area. Kosmos and its block partners are currently drilling the Mahogany Deep-2 appraisal well using the "Aban Abraham" drillship.
