Mahogany Deep-2 appraisal well confirms southerly extent of Jubilee field

Tullow Oil plc (Tullow) announces that the Mahogany Deep-2 appraisal well offshore Ghana confirmed the down-dip extent of the main Jubilee reservoirs in the West Cape Three Points Block and intersected two new light oil accumulations. Good quality reservoirs were encountered in the Mahogany Deep section but were water bearing at this location. Mahogany Deep-2, drilled 3 km from Mahogany-3, is .... [+ read more] the furthest down-dip Jubilee well in the West Cape Three Points licence. Results of drilling, wireline logging and samples of reservoir fluid indicate that the well has encountered good quality hydrocarbon-bearing reservoir sandstones in three zones. An interval of 12 metres net pay has proved an extension of the main Jubilee reservoirs. In addition, a new shallower accumulation, with 2 metres net pay, was encountered and supports exploration prospectivity in undrilled areas to the south and east. In total, the well intersected 53 metres of net reservoir sandstones, 20 metres of which were in the Mahogany Deep section. These were found to be water bearing at this location but are not connected to the Mahogany Deep accumulation at Mahogany-3. Further extensions to the Mahogany Deep accumulation may exist to the south and east of Mahogany-3. A new reservoir was also encountered in a deeper stratigraphic level beneath the Mahogany Deep section and an oil sample was successfully recovered from a 1 metre zone which has not been encountered in any other wells in the West Cape Three Points licence to date. The new accumulations discovered by the well will now be evaluated using the recently reprocessed high resolution 3D seismic data and may be the target of future drilling. Further potential extensions of the Jubilee field and associated prospectivity will be drilled early in 2010. The Aban Abraham dynamically positioned drill-ship drilled Mahogany Deep-2 to the current depth of 4,326 metres in water depths of 1,354 metres. 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).

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 .... [+ read more] 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.

Successful Test of the Viodo 4 Well on Marine XI

The Viodo Marine 4 vertical appraisal well ("VIM-4") located in the Marine XI Block offshore the Republic of Congo (Brazzaville) has tested at a combined maximum flow rate of approximately 2,600 barrels of oil per day ("BOPD") and 7.0 million standard cubic feet of gas per day ("MMSCFD") following two drill stem tests ("DSTs"). In the first drill stem .... [+ read more] test from the deeper Carbonate section between 2,240 to 2,273 metres, the well flowed at initial post-acid rates of approximately 2,600 BOPD and 2.5 million MMSCFD on a 3/4 inch choke. Flow rates stabilized at approximately 1,100 BOPD on a 1/2 inch choke after an approximate seven hour flow period. A test of the upper Carbonate section, between 2,205 and 2,230 metres, flowed at post-acid rates of approximately 4.5 MMSCFD. The objectives of the well are to further delineate the field, gather data that would allow the 3D seismic to be used to map the distribution of reservoir quality limestone and to test the effectiveness of a completion strategy that could be applied to high angle development wells. The results of the well and the reprocessed seismic will now be incorporated into a 3D model that will be used as a tool to assess the commerciality of the accumulation. As planned the well will be plugged and abandoned and the jack-up drilling rig Pride Cabinda will be released.

New North Sea discovery

More oil and gas have been discovered by StatoilHydro with an exploration well drilled about 35 kilometres east of Gudrun in the North Sea and roughly 30 kilometres south of Grane. Gas and oil with associated condensate were found in rocks interpreted to be Jurassic or Triassic/Permian. An exploration well proved gas and oil about 6.5 kilometres further north .... [+ read more] in the autumn of 2007, and the latest discovery probably forms part of the same hydrocarbon system. Preliminary estimates put total recoverable gas resources in these two finds at three to 10 billion standard cubic metres (scm). More detailed studies of collected well data will be needed to evaluate the resources and determine further activity around the discovery. “This represents a new and exciting play,” comments Noralf Steinsland, StatoilHydro’s licence manager for the North Sea. “It increases opportunities for further discoveries in a mature area where we have strengthened our position through new licences and farm-ins.” The discovery well was drilled from the West Epsilon rig to a vertical depth of 2,324 metres beneath the sea surface, in waters 109 metres deep. It will now be permanently plugged and abandoned. In addition to StatoilHydro, with a 40% holding, the partners in production licence 265 are Petoro with 30%, Det Norske Oljeselskap with 20% and Talisman Energy Norway with 10%.

Encouraging gas discovery in Ragnarrock Graben

Det norske oljeselskap (DETNOR) has made an encouraging gas discovery in exploration well 16/2-5 in PL 265 on the Ragnarrock Graben prospect. Preliminary analyses indicate that the gas discovery in Graben could be connected to the previous gas discovery made in basement in well 16/2-4. If this is correct, the chances are good that the necessary volumes for a viable .... [+ read more] development are present. A full scale production test was carried out in the gas zone with maximum production of 120 000 scm per day, or 750 boepd, plus some condensate. The reservoir is however complex and consist of conglomerate from the pre Cretaceous. The production could thus vary considerably in different parts of the reservoir. An additional well is planned drilled in PL 265 and may offer additional information about the gas potential and flow rates in the basement. The information gathered so far indicates that there are considerable amounts of gas present in the license (Basement north and Graben). However, the reservoirs are challenging and more geological and technical work is necessary in order to mature an economical viable development. Det norske see the results from the well as positive for further development of the resources in PL 265. The gas discovery in 16/2-5 increases the probability that gas is present also in the southern part of basement (Basement south). This is the fourth exploration well in Production License 265. The well was drilled to a vertical depth of 2,324 meters below sea level and into the basement. The water depth is 109 meter. Well 16/2-5 was drilled with the drilling facility West Epsilon, which will now sail to the Sleipner Field in PL 025 in the North Sea.

Gas condensate find at Veslefrikk

A small gas condensate discovery has been made by StatoilHydro in the Canon prospect, about 11 kilometres west of the Veslefrikk field in the North Sea. The purpose of the exploration well was to prove petroleum in a fault block between the Huldra and Oseberg fields. The well tested two reservoir levels – an upper one belonging to the Brent group .... [+ read more] and a deeper level in the Statfjord group. "The exploration well struck gas condensate in the Brent group but the reservoir was thinner than expected and the find is probably not commercial," says Tom Dreyer, StatoilHydro's vice president for infrastructure exploration in the North Sea. Deeper in the structure, the well struck sandstone belonging to the Statfjord group. Data gathered from this interval showed that the reservoir consisted of tight sand and was probably full of water. Drilled by the West Alpha semi-submersible, the well will now be permanently plugged and abandoned. The rig's charter with StatoilHydro will terminate once the well is completed. This is the second well to be tested in the Canon structure. An exploration well drilled in 2000 provided inconclusive results about the economic potential of the structure. The licensees in production licence 052 are: operator StatoilHydro (18%), Petoro (37.0%), RWE Dea Norge (13.5%), Revus Energy (4.5%) and Talisman Resources Norge (27.0%).

Oil discovery close to the Vigdis field

StatoilHydro has struck oil during the drilling of an exploration well and a sidetrack north of the Vigdis East field in the North Sea. The proven recoverable resources are estimated at about 25 million barrels of oil. The well confirmed the existence of a 280-metre oil column in rocks with good reservoir properties. "Our exploration activities close to fields on stream .... [+ read more] are successful and the discovery again confirms that there is still a great potential in this part of the North Sea," says Tom Dreyer, StatoilHydro's vice president, infrastructure-led exploration, North Sea. The exploration well was drilled into the Vigdis North-East prospect, located 3 kilometres south of the Snorre field. The purpose of the well was to confirm the existence of hydrocarbons in Lower Jurassic reservoir rocks belonging to the Statfjord group. The purpose of the side-track was to get a better overview of the resource potential. The discovery will be developed towards the Tordis or Vigdis fields. "Such discoveries close to established infrastructure help extend the life of the installations and capture the potential offshore", says Kari Flesjå, team leader for infrastructure-led exploration in the North Sea. Drilled in 292 metres of water the well will be permanently plugged and abandoned. Extensive data acquisition and sampling took place during the drilling operation.

New discovery near existing infrastructure

Oil and gas have been encountered by StatoilHydro in the Katla prospect, which lies 11 kilometres south-west of the Oseberg South platform operated by the group in the Norwegian North Sea. Proven recoverable volumes are 50-80 million barrels of oil equivalent, with the bulk of the resources occupying the Tarbert formation in the upper Brent group. Oil and gas were .... [+ read more] found in this structure, while gas was also proven in Upper Jurassic reservoir rocks belonging to the Heather formation. “We’ve had great success with exploration close to producing fields over the past year,” says Tove Stuhr Sjøblom, head of exploration for the Norwegian continental shelf. “This is another discovery which confirms that it’s still possible to find relatively large volumes of oil and gas in established areas such as Oseberg.” The find will probably be developed and produced through a tie-in to one of the existing subsea installations in this part of the North Sea. “Given that it lies close to an existing field and can quickly be brought on stream, this is a very interesting volume,” says Tom Dreyer, head of North Sea infrastructure-led exploration. “The discovery is a good deal larger than we usually find in wells close to existing fields.” Although the discovery has not been tested, extensive data gathering and coring have been carried out. “Discoveries like this are important for maximising the recovery of resources from the NCS, because they help to extend the production life of installations,” says Ms Sjøblom. Apart from StatoilHydro as operator with 49.3%, licensees in production licence 104 are ConocoPhillips with 2.4%, ExxonMobil with 4.7%, Petoro with 33.6% and Total with 10%.

Hyedua-2 appraisal well flows at 16,750 barrels of oil per day (bopd)

Tullow Oil plc (Tullow) announces that the Hyedua-2 well, which has been drilled to appraise the Jubilee field offshore Ghana, flowed at a stable rate of 16,750 bopd. This result confirms good reservoir connectivity and very high productivity and also indicates that future production well deliverability will be in excess of 20,000 bopd. The Hyedua-2 appraisal well, which lies in the .... [+ read more] Deepwater Tano licence, has been drilled to a total depth of 3,663 metres by the Blackford Dolphin rig in a water depth of 1,246 metres. The well intersected 55 metres of high quality oil bearing reservoir sandstones of which a 41 metre section has been production tested. Three flow tests were conducted and a maximum rate of 16,750 bopd of 37 degree API gravity crude oil and 21 million cubic feet per day of associated natural gas was achieved through a 88/64” choke with a tubing head pressure of 1,380 pounds per square inch. This confirms that Jubilee is a highly productive reservoir and that once the wells have been configured for long-term production they will be capable of producing at rates in excess of 20,000 bopd. Hyedua-2 is located on the north-west flank of the field and the excellent reservoir properties measured during this flow test are expected to be even better in the core area of the field. Stable oil and gas flow rates were maintained throughout the tests and the pressure data indicates that it is connected to a large pore volume. This excellent reservoir continuity enhances our expectation of connectivity between the planned production and injection wells and we are currently assessing the positive impact on Phase 1 reserves. The combination of outstanding reservoir productivity and continuity is very encouraging for Phase 1 of the Jubilee development which remains on schedule for first oil in the second half of 2010. The Hyedua-2 well will now be suspended, as planned, for later completion as a production well. Tullow (49.95%) operates the Deepwater Tano licence. Other partners include Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest). Tullow is also the Unit Operator of the Jubilee field.

Successful Mahogany-3 appraisal and exploration well

Tullow Oil plc (Tullow) announces that the Mahogany-3 well located in the West Cape Three Points licence offshore Ghana has intersected significant light oil columns in both the Jubilee field appraisal objective and also a deeper exploration target. In total, 33 metres of net pay have been penetrated. The primary objective of Mahogany-3 was to appraise the Jubilee field reservoir section .... [+ read more] away from the strong seismic amplitudes which have been the main targets to date. Results of drilling, wireline logs and samples of reservoir fluid indicate that 16 metres of high quality stacked oil bearing sandstones have been encountered. This confirms a significant extension of the Jubilee field to the southeast. The secondary objective of the well was to drill Mahogany Deep, an exploration target which has been identified on 3D seismic but lies at a previously untested stratigraphic level. In this section, the well encountered 17 metres of good quality oil bearing reservoir sandstones at levels significantly deeper than the oil water contacts previously intersected on the Jubilee field. This success opens up further potential in the region and is the subject of ongoing evaluation. The well has been drilled by the Eirik Raude semi-submersible rig to a depth of 4,028 metres in a water depth of 1,236 metres. Once wireline logging operations have been completed, casing will be set in advance of further drilling which is being carried out to gain further information on the regional geology. Following the conclusion of activities on Mahogany-3, the rig will move to the Tweneboa-1 exploration well location in the Deepwater Tano block. Drilling activities are expected to commence before the end of January. Tullow has a 22.9% interest in the West Cape Three Points licence. Other partners include Kosmos Energy (Operator 30.875%), Anadarko Petroleum (30.875%), the E.O. Group (3.5%), Sabre Oil & Gas (1.854%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).
