LIBYA: AGOCO Finds Some In the Ghadames

Libya’s state hydrocarbon company NOC has announced a new oil and gas discovery that its partner the Arabian Gulf Oil Company (AGOCO) made Ghadames Basin. The well is located approximately 500 kilometers south of Tripoli and 170 kilometers west of the Hamada oil field.

The wildcat D1-NC7A, well encountered multiple shows from three levels of reservoir formations. At a depth of 2522 to 2530 metres in the Upper Acacus sandstone formation, tests flowed oil at a rate of 668 BOPD and 22.5 MMcf/d of natural gas. At a vertical depth of 2724 to 2720 metres in the Middle Acacus sandstone formation, tests showed oil flowing at a rate of 500 BOPD and 21.1 MMcf/d of natural gas. In the Lower Acacus sandstone formation with vertical depths ranging from 2752 to 2884metres, multipe tests showed oil flowing from a rate of 790 BOPD to 1,251 BOPD and gas flowing at a rate of 27.6 MMcf/d to 28.9 MMcf/d. All oil has measured 64.4 degrees API.

Vegas Wins The Bet In Northwest Gemsa

Circle Oil has announced the successful re-entry and sidetrack of well Al Amir-1X, in the North West Gemsa Concession, Egypt. Al Amir-1X encountered oil in a single pay zone in April 2005. This re-entry was done to redrill and test a new sidetracked section of the well in order to re-appraise the well as a potential producer. Following sidetracking to a total vertical depth of 1606metres, two pay zones have been identified.

The previously discovered upper pay zone in the Gharib formation dolomites has been confirmed by the sidetrack well. This upper zone has been tested with a sustained rate of 416 BOPD. A new lower pay zone has also been encountered in the Gharib formation dolomites. The company intends to test and confirm the flow rate potential from the new lower pay zone when the well is brought into commercial production.

Vegas Oil and Gas operates the North West Gemsa Concession with 50% interest and partners include Circle Oil Plc (40% interest) and Premier Oil Plc (10% interest). The concession covers an area of over 400 square kilometers and lies about 300 kilometers southeast of Cairo, in a partially unexplored part of the Gulf of Suez Basin. The concession agreement includes the right of conversion to a production license of 20 years, plus extensions, in the event of commercial discoveries. The Egyptian General Petroleum Corporation (“EGPC”) has given a position response to the partners’ ‘Declaration of Commerciality’ submission made to them for both wells.  Development plans to bring the wells into early commercial production have also been submitted to EGPC.

NIGERIA: Boi Area Poses Pressure Challenges For BG

BG, the British gas company, lost the original Ogide-1 hole after it took a kick at an undisclosed depth. The rig moved 80 metres updip but continued to chase the same targets. Ogide -1 is located in the vicinity of Boi-1, drilled by Statoil (in 1996), in what is now known as OPL 286-DO, in deepwater Niger Delta. Statoil’s reports indicate that it encountered some gas in the hole but couldn’t reach the target depth because of pressure problems. The campaign ran out of casing strings, and stopped at a total depth of about 2,300metres subsea. The conventional thinking is that a mud diapir is transmitting much of the pressure throughout the system. Statoil walked out of OPL 213 in 2000, handing over the operatorship to Chevron, who carved out Oil Mining Lease (OML 132) and relinquished that part of the lease in 2005. It’s not clear whether BG will still attempt to drill what it calls Boi-1 deep, after Ogide, or whether it has already combined the objectives of Ogide-1 with the objectives of Boi deep. The Boi deep was to test the levels that Statoil couldn’t reach in 1996. BG’s geoscientists are deeply divided over the choice of the Boi area for their first outing in deepwater Nigeria. The company is also technical partner in OPL 284, located north of Agip’s OML 134.

Dana Is Cautious About Akhenaton- 1 Results

Dana Petroleum has suspended Akhenaton-1, in the South October concession, offshore Gulf of Suez for potential re-entry at a later date. “The data is important for assessing further prospectivity in the South October concession”, according to a company release. Akhenaton-1 was drilled to a total depth of 4060metres below sea-level, penetrating both the primary and secondary targets. The top of the secondary Thebes target was encountered at 3567metres below sea-level and the primary Nubia target was encountered at 3988metres. A full suite of electrical wireline logs was acquired, including the use of a formation imaging tool. Although the Nubia was water bearing, oil was encountered in the shallower Thebes and Sudr formations with high oil saturations seen over an extensive vertical interval of 272metres. The Thebes and Sudr formations are low porosity fractured limestones and an imaging tool was therefore used to gather information on the extent of fracturing. A thorough interpretation of the acquired data will now be required before an assessment can be made of the commercial viability of this oil discovery. The 103 drilling rig has moved to the SouthEast July concession in the Gulf of Suez where Dana is drilling the South July-1 well.

Vegas Tries Out In Western Desert

VEGAS OIL & GAS SA WAS ON COURSE to suspending the new field wildcat Al Magd 1 (Hh 31-2) as a discovery as of March 15, 2008. The well is located in the Alam El Shawish West block (Block I). The Total Depth as of mid March was 3,200metres, but the prognosed Total Depth PTD was 3,487metres. Vegas officials say that the main objective of the well were the Abu Roash “C”, “E” and “G” units and the Bahariya Formation. The rig is L/R “Nafla-2.

Medex On The Search In Illizi


FRANCE BASED INDEPENDENT MEDEX, has suspended the appraisal well lssaouane Nord B-2 at a depth of  972metres. The target was F2 sandstones. The well is located in onshore Erg Issaouane Block 226, in Illizi Basin in South Eastern Algeria. Issaouane Nord B-2 was logged before suspension.

Malaysians Bank On Mauritana


PETRONAS, THE STATE HYDROCARBONcompany of Malaysia, has spudded a new field wildcat Khop 1 off Mauritania. The well, being drilled by the semi submersible rig Atwood Hunter, is located in Block 6 of the PSC Area C, 70km off the coastline in water depth of 925m. The well is targeting a four-way dip Albian  structure of 220 sq km, with a vertical closure of l,200m. The proposed Total Depth (PTD) is 4320metres. Partners are expecting recoverable reserves ranging from a 100MMBO (P90) to 1,000MMBO(P90).  Petronas operates Block 6  with 72.578% and its partners include Tullow 22 .422%, Roe 5%.
