Agip Missed The Target In Oberan 2

Agip missed the expected reservoir in Oberan -2, inspite of the large expectations created by the discovery well. Oberan -2 is located in the Agip operated Oil Mining Lease (OML)134. Delays in the approval of contract for the three dimensional seismic acquisition, led the company to go ahead and drill the appraisal well, taking advantage of an available rig. “They thought they had enough information with the existing Agip seismic data to drill the appraisal”, a source said. They were wrong. Lessons learned: “They are going to take their time with the third well, integrate all available data into the new 3D data on the structure and evaluate. Oberan 3 is not likely to be drilled until the second or third quarter 2010”.


Hess Chews Dust in the Tano

In Ghana, Hess has completed drilling operations on the Ankobra-1 well, located on the Deepwater Tano Cape Three Points license, without encountering commercially significant hydrocarbons. The well was drilled to a depth of 3962metres in 1732metres of water. Hess holds a 90 percent interest in the license in partnership with Ghana National Petroleum Company. Hess is currently acquiring 1618 square kilometres of new 3D seismic in anticipation of a well to be drilled in the unexplored western half of the license areas.


Uganda: Buffalo Is The Biggest In Butiaba

Heritage Oil ‘s rank wildcat Buffalo-1, a new discovery in the Butiaba region of Block 1 in Uganda, is potentially the largest in the Butiaba Area to date. The well encountered 15 metres of net gas pay and over 28 metres of net oil pay within a 123 metre gross interval. The well was in an early stage of evaluation as of December 2008.

Buffalo-1 was drilled some 500 metres from the crest of the structure to a total depth of 637 metres. Downhole pressure testing and sampling confirmed the presence of dry gas and moveable oil that has been recovered to surface. The company says that reservoir quality in all pay zones is excellent, with the gas and oil columns encountered being 48 metres and 75 metres respectively with the potential to be even larger.

Executives at Tullow Oil, which is partner to Heritage Oil on the lease, enthuse that “Buffalo-1 is the fifth successful test of the Victoria Nile delta play fairway within the Lake Albert Rift Basin”. It was drilled 16 km north-east of the Warthog-1 and Kasamene-1 discoveries. This latest result extends the play further north and de-risks several adjacent prospects, located in Blocks 1 and 2, which are scheduled for drilling in 2009.

The well has now been suspended as a future producer and the rig moved five km south to the location of the Giraffe prospect where drilling commenced in late December 2008. This well will also appraise some of the upside potential of the Buffalo discovery.

Tullow has interests in three licences in the Lake Albert Rift Basin in Uganda. Tullow operates Block 2 with a 100% interest and has a 50% interest in Blocks 1 and 3A which are operated by Heritage Oil (50%).


SOMALIA: Africa Oil Completes Somalian Shoot

Africa Oil has successfully completed a 2D seismic survey in the Dharoor Valley of Puntland Somalia. A total of 782 km of vibroseis data, comprising a grid of 15 lines, were recorded by IMC Geophysical of the UK.

The Company will now process the new survey and combine the 555 km of earlier data into its seismic database. Mapping of this combined survey should commence in early 2009 and drilling locations will be selected before the end of Q1, 2009. This will permit mobilization of a drilling rig to fulfill the company’s drilling obligations under the Production Sharing Agreements before the end of 2009.

TOTAL Makes Significant Discovery at Etisong

French supermajor TOTAL has flowed 6,000 barrels per day 40° API oil, in turbiditic reservoirs, in the wildcat Etisong 1, located in the southeastern corner of Oil Mining License (OML) 102, offshore southeastern Nigeria.

“The well constitutes the first step of an exploration and appraisal programme from 2009 to 2010 designed to demonstrate the feasibility of a new development pole on OML102”, according to a company release. That new development pole will combine the Etisong main discovery and the surrounding structures.

OML 102 is run by the joint venture between Nigeria’s state hydrocarbon company Nigerian National Petroleum Corporation (NNPC), which holds 60% and TOTAL, which operates the JV with 40%. “The Etisong main discovery when confirmed by further appraisal results should contribute toward helping to meet the Government’s objective of renewing national reserves”. Etisongi\ is located in a water depth of 70 metres, in the area within about 15 kilometers from the Ofon Field.

The Etisong-1 well was drilled by the Trident VIII jackup to a total depth of 2,207 metres.


CNODC Processes OPL 471 Data

CNODC Nigeria has initiated prequalification of contractors to process the 3D seismic data it acquired on the Nigerian Oil Prospecting Lease, OPL 471, in shallow offshore western Niger Delta. The China National Oil Development Corporation (CNODC), a subsidiary of the Chinese state behemoth CNPC, wants a full kirchoff post stack time migration (PSTM)processing for the 1,200sq km survey, which was acquired in 15-45metre water depth at bin size of 12.5 x 25 and a 60 fold coverage. The company says record length is nine seconds(in time depth). CNODC won OPL 471 in a bid round in 2006 and signed a Production Sharing Contract with the state hydrocarbon company NNPC in 2007. The seismic processing contract is to be awarded by first quarter 2009 and processing must be completed in a maximum of six months from receipt of input tapes


Sapetro Drills Seme SW

Nigerian independent South Atlantic Petroleum Ltd (Sapetro) may have commenced drilling the near-field exploration well Seme SW, around the Seme oil field, in Block 1. The Sèmè SW target had previously been identified but whether this becomes the company’s first operated well in Benin remains to be seen. It is understood the Noble Drilling’s jack up rig ‘Don Walker”, currently in Cameroon, has been contracted to do the job as the structure lies in around 30metres of water. Block 1, including Sèmè field, covers 551 sq km in the shallow waters of the Benin Embayment, at the maritime border with Nigeria.

It was awarded in December 2004 and is held 100% by Sapetro. In March 2007, Sapetro completed a 360 sq km 3D seismic survey over the Sèmè field and its environs. It is believed this data will form the basis for a redevelopment plan of the Sèmè field aimed at putting the field back into production. Sapetro has a share in the development of the Akpo deepwater field off Nigeria. Its chairman is General Theophilus Danjuma, formerly minister of defense under Olusegun Obasanjo.


Total Confirms Mostarda Discovery

ANGOLA

FRENCH MAJOR TOTAL HAS SUCCESSFULLY appraised its 2005 discovery Mostarda-1. The appraisal well Mostarda 2G1, was suspended at a Total Depth of 5,150metres subsea, but TOTAL did not provide details of the hydrocarbon find. Mostarda 1 was drilled in the Ultra deepwater Block 32 in late 2005 and flowed 5,347 BOPD of 30 degree API oil.


StatoilHydro Set To Plunge Into The Indian Ocean

NORWEIGIAN OPERATOR, STATOILHYDRO has mapped out plans for a large two dimensional 2D seismic coverage of the 11,099- sq km deepwater block 2, frontier acreage of the Indian Ocean in the course of 2008. A first well is still far in the distance, but state hydrocarbon company Tanzanian Petroleum Development Corporation TPDC has a 10% back-in right in the event of a commercial find..
