Horn Returns To The Seismic Board

After two disappointing wells back to back, Horn Petroleum is focused on preparations for a seismic acquisition in Somalia. The campaign, targeting the Dharoor PSA , will include a regional seismic reconnaissance grid in the previously unexplored eastern portion of the basin.
Efforts are now focused on identifying a drilling location in the western portion of the basin where an active petroleum system was confirmed by the recent drilling of Shabeel-1 and Shabeel North-1. This seismic programme is expected to commence in the first half of 2013.
The company continues to pursue efforts to drill an exploration well in the Nugaal PSA and is working with the Puntland government authorities to move this project forward.

Maersk May Break The Block 16 Jinx

Maersk Oil has reported flow rates of up to 3,000BOPD on a 36/64-in choke in Caporolo-1 in Angola’s Block 16. The company drilled the well as a step-out exploration probe on a structure 13 km from the Chissonga discovery. This could prove a field extension, or an additional development to the Chissonga structure, on which Maersk has drilled three appraisal wells. If a commercial field development could be established, Block 16 would be out of the trap it’d been consigned to since Shell walked out on the lease in 1997.

AP Shoots Large In The Transform Margin

African Petroleum completed a   4,200 sq km 3D seismic survey over Blocks CI-513 and CI-508, in early October 2012. The work was done by the Chinese geophysical contractor BGP Marine (Prospector PTE Ltd).
The acquisition commenced in April 2012, using the 12- streamer vessel “BGP Prospector”, and the CI-513 survey was completed in mid-July 2012. The vessel continued onto the CI-508 & CI-509 survey, which was completed post quarter end, on 9 October 2012.
The CI-508 survey was being acquired by African Petroleum on behalf of Vitol and partners over Block CI-508, and is subject to a cost sharing agreement executed in June 2012, whereby all seismic acquisition and processing costs are shared on an equal basis.

Murphy Comes Up Dry In The Congo

Murphy Oil has plugged and abandoned an unsuccessful offshore well located in the Mer Profonde Nord (MPN) permit in Congo Brazaville.

The company estimates a cost of about $48MM on the drilling of Opale Marine – 1 well in the MPN Block, which will be accounted in its 4th quarter 2012 report. Murphy will also take a non-cash charge of $29MM in the quarter to write off the Titane Marine -1 well which was drilled in October 2010 and was suspended pending results of additional exploratory drilling on the block.


Tullow Fares Poorly In Ghana’s Okure-1

The news were far from upbeat when Tullow Oil gave an update on its Okure-1 exploration well, on the Deepwater Tano Licence offshore Ghana. The company didn’t say exactly what the net oil count was, after the well had reached total depth of 4,511 meters. The gross hydrocarbon column given was 17metres.
Tullow admitted there was a “low net-to-gross” interval and the sands were “non-reservoir quality formations at the main objective levels below the TEN cluster”.  TEN refers to Tweneboa, Enyenra and Ntomme fields, which are to be jointly developed as TEN Project.

The sands in Okure-1 are Turonian age sandstones within an overlying secondary objective. Light oil with a 40° API was recovered from this interval.

Conoil Targets 20,000 Feet With Discovery Well

Photos courtesy of MegaDrill and IDSConoil’s Ango-1, the new field wildcat being drilled by the new build swamp barge Majestic, is expected to drill to 19800 feet(or 6035metres). Our report, last week, mistakenly reported that the proposed TD was 18000(5486metres). A depth of 19,800ft Measured Depth (with TVD around 17990feet, or 5852metres) is clearly more than a thousand feet deeper than the deepest onshore well in the Niger Delta: Agip’s Tuomo-2.
We reported last week that the well, located 30km North east of Otuo South field, in Conoil operated Oil Mining Lease(OML) 59, in southwestern Niger Delta basin encountered over 150 feet of suspected hydrocarbon column at around 16000ft(4876metres) TVD, which itself is very deep by Niger Delta standards. If this turns out to be a producing reservoir, it will be one of the two deepest pay zones in onshore Niger Delta. The original hole has been sidetracked, but the objectives remain. Conoil expects to hit another payzone at about 18,000feet TVD.


Conoil On The Course Of A Major Discovery

The new build swamp barge Majestic drilled through over 150 feet of suspected hydrocarbon column in Ango-1, a new field  wildcat located 30km North east of Otuo South field, in Conoil  operated Oil Mining Lease(OML) 59, in southwestern Niger Delta basin. The High Temperature, High Pressure(HTHP) rig got stuck and pulled out of hole from about 16,000feet(4,876metres) deep, in true vertical depth, where the column was encountered. It is currently on sidetrack. “If the column turns out to be oil, it will mean an entirely new play in that part of the Niger Delta basin”, says an official of the Department of Petroleum Resources(DPR), the Nigerian state regulatory agency.

Rig Activity Paces Up In Uganda

Rig Activity Paces Up In Uganda

Uganda is experiencing its most intense drilling campaign since commercial oil was discovered six years ago, according to the country’s Chamber of Mines and Petroleum.

The major activity are in both blocks 1 and 2, the areas operated by France’s TOTAL and the Irish firm Tullow, the Chamber’s journal reported. Five rigs have been deployed on several locations in the country in 2012, the highest number in a year ever.

Appraisal drilling and well testing activities in the Kigogole, Nsoga, Ngege, Ngara area commenced in 2012. This is the precursor to field development.

Tullow On Fourth Kenyan Well, Plans For Ethiopia

Tullow Oil Plc is drilling its third operated well and the fourth in which it is a participant, in Kenya. The company opened up the country as a possibly commercial hydrocarbon province, with Ngamia 1 oil discovery (in Block 10BB), logging 143 metres of oil pay over several zones and suspending the well at a total depth of 2,430metres at the end of June 2012. The company proceeded to spud Twiga South 1(Block 13T) on August 31, two months after suspending Ngamia. Results are expected in October 2012.

Meanwhile, Tullow was a 15% participant in the drilling of the offshore well Mbawa-1(Block L8), in the Lamu Basin, operated by Apache. The well encountered 52 metres of net gas pay, the first commercial encounter in offshore Kenya. It was plugged and abandoned in mid -September 2012.

ENI Enlarges The Ghanaian Oil Tank

ENI Enlarges The Ghanaian Oil Tank

Italian major ENI encountered  76 meters of gross oil pay and 28 metres gross gas and condensate sands in Cretaceous sequences in the Sankofa East-1X well on Ghana’s Offshore Cape Three Points (OCTP) block. It is the company’s first crude oil discovery on the block, which was always known to be water bearing. Production test yielded 5,000BOPD of what ENI called “high quality” oil in the sand interval. The company said that flow rates were constrained by surface infrastructures.

ENI plans to drill more wells to delineate the size of the discovery and confirm the feasibility of commercial development.
Sankofa East-1X well reached a total depth of 3,650 meters, in 825 meters of water.
