Scottish independent Petroceltichas plugged and abandoned its Mesaha-1 exploration well, but got successful in South Damas 2 development probe. Both wells are in Egypt.
Mesaha 1 was abandoned after the firm failed to find hydrocarbon indicators in the hole.
The company says that the well has provided significant new data on the Mesaha basin statigraphy, which will be incorporated in a review of the regional geology prior to the planning of any future work on the block. Mesaha-1, drilled to a total depth of 2,129metreswas finalized at a cost of $10.3 million(gross) Petroceltic holds a 40-percent working interest in the concession.
Petroceltic says that South Damas-2 development well, in the Nile Delta, has been successfully drilled to 1,432metres and completed using the Tanmia-1 rig and is expected to begin production in late February. The well is expected to increase the total South Damas field production rate to more than 20 million cubic feet of gas per day(from 12 million cf/d).
LONGREACH has completed its 2D seismic programme on the operated Sidi Moktar Licence, onshore Morocco, on time and in budget, it claims.
520 km of high quality seismic data were acquired in 47 lines over the portfolio of prospects and leads in fulfilment of the Licence commitment of 500km, Longreach claims in a release. Priority lines, over Longreach’s drill-ready targets, Koba and Kamar, have been processed by Key Seismic in Calgary using the processing sequence and parameters determined by Longreach during the extensive reprocessing project completed in 2012. The priority lines are being incorporated into the Company’s interpretation to finalise the well locations for the 2013 drilling programme. In addition, the survey was designed to high-grade and promote existing leads to prospect status, the company says.
The survey was conducted by Prospectiuni in compliance with the approved Environmental Impact Assessment to the highest international HSE standards”, Longreach claims.
Italian giant Eni will be producing about 2,000 Barrels of Oil Per Day(BOPD), in each of two development wells to be drilled on a new field it just discovered. Eni and its partners encountered a total oil pay of about 80 meters in multiple sandstone reservoirs on the Rosa North prospect, at the depth of over 2,200 meters. But the result of the well tests apparently has shown that technical allowable for any development cannot be more than 2,000BOPD.
Rosa North is the third discovery made on the concession over the last three years and follows Arcadia (2010) and EmryDeep (2012) fields. The concession still holds significant resource potential which is confirmed by the growing production, exploration drilling results as well as recently acquired 3D-seismic data and the new geological model derived from it. Project partners are ENI through its subsidiary IEOC (56%), LUKOIL Overseas (24%) and Mitsui (20%). LUKOIL joined the project in 1995. More than 8.4 million barrels of oil were produced on Meleiha in 2012.
Vegas Oil and Gas is drilling an appraisal to the Al Ola-1 discovery/producer in Egypt’s North West Gemsa Concession. Al Ola-3 is also an injector well, targeting the Kareem sands, located to the south of Al Ola-1 and Al Ola-2 wells. The rig was mobilised to the site, following the successful completion of the AASE-12X ST1 well, which is in the south central part of the AASE field, in the same acreage.
Vegas operates the NW Gemsa concession with 50% and its partners include Circle Oil(40%) and Sea Dragon (10%). Gross production from the AASE, Geyad and Al Ola fields is approximately 9,300BOPD(gross).
German independent, E.ON E&P has successfully completed the drilling and testing of the 7th exploration well in block 405a and found oil and gas in the NEY-1 well. The Rhourde Yacoub license is located in the eastern Algerian Sahara, around 250 kilometres south-east of Hassi Messaoud.
“We are very pleased with another successful discovery of oil and gas in Algeria. The results of this well are very encouraging and we will now enter a phase where we will drill several wells over the next two years to evaluate the extension of the discoveries,” says Hubert Mainitz, Managing Director of E.ON E&P Algeria. The Rhourde Yacoub license is operated by E.ON E&P with an equity share of 49%. Sonatrach holds the majority of 51%. The Rhourde Yacoub license is located in the oil and gas-prone Berkine basin and E.ONE&P was awarded this block in a license round in December 2008. Since then the company has drilled seven exploration wells and made several encouraging discoveries in the license area.
Australian operator Cooper Energy has secured a drilling rig for its Hammamet West-3well on the Bargou exploration permit, offshore Tunisia.
The Bargou joint venture, with Cooper as operator signed a letter of intent with Romanian Grup Servicii Petroliere (GSP) for the use of the jackup rig “GSP Jupiter” to drill thewell which is scheduled to spud in December 2012.
HammametWest-3 is being drilled to further assess the oil resource within the Abiod formation. Cooper intends to drill the well to penetrate the reservoir with a slightly deviated pilot hole. A highly deviated wellbore will then be drilled and tested, to confirmthe oil productivity of the formation.

Exxoil was preparing to spud Bou Argoub-1 (BAB-1) in the SouthWest Belli area of the Grombalia Permit in Tunisia, as of the time of our going to press in mid August 2012. The prospect is near the Belli, El Manzah and Beni Khaled fields. Exxoil’s programme says ” the drilling of this well will commenceearly in the second half of 2012″.
The BAB-1 well will have an expected TD of 4,429 feet (1,350 meters) and is targeting a fault-bounded structural culmination crossing two vertically stacked fractured carbonate reservoirs, the Eocene Bou Dabbous Formation
and the Late Cretaceous Abiod Formation. These are the main oil-producing formations in the north eastern part of Tunisia.
The Grombalia Permit covers an area of 1,078 square miles (2,792 square kilometers). The partners include Exxoil Tunisie Ltd (65% working interest and operator) and Circle (35%working interest).
ADX Energy Limited has finally plugged and abandoned Sidi Dhaher 1, in the Chorbane license, Tunisia, after a DST exercise in which 90 barrels of mud filtrate and formation water were recovered. The well has now been plugged and abandoned.
It’s not clear whether sheer incompetence or unbridled optimism led to the wasteful testing. ADX’s announcement did not say that logs were interpreted before the DST was carried out. “The test results are in apparent conflict with the previous analysis in the fall of 2011”, the company explains on its website. Still ADX beat its chest in an announcement: “Despite good flow rates from the two reservoir zones and substantial amounts of fluids being produced fromthe upper reservoir zone, the fluids were not observed to contain any quantities of oil”, it says in a release.

BP is delaying its plans to plunge into the geologically high risk deepwater Meditteranean. The British major is changing the rig,” and will likely drill offshore in 2011.”
BP is due to drill at least five wells in the Gulf of Sirte. The company is changing rigs from one owned by Noble Corp., to a new one, currently being prepared in the Gulf of Mexico, which is owned by-Pride- International Inc.
Results of drilling in deepwater Libya have been mixed, with Hess making modest gas discoveries and ExxonMobil coming out entirely dry. In nearby Egypt, deepwater Mediterranean has favoured BG in NEMED but has proved disappointing for Shell.
Petronas, the Malaysian state hydrocarbon company, was drilling ahead the Gharabi-1 exploration well off Mauritania with the rig Maersk Deliverer. Gharabi1 is located in Block C6, approximately 22 kilometres southwest of the Cormoran-1 discovery. The planned total depth of the well is around 4,880 metres and the located in a water depth of 1,791 metres. Participating Interests in Block C6 are: Petronas (Operator) 72.58%, Tullow 22 42%; Roc Oil 5.00%
