Chevron Has Drilled 22 of 36 Wells In The $1.2Billion Deal

Chevron Nigeria has concluded slightly less than two thirds of the drilling funded by a consortium of Nigerian and international lenders, led by Standard Chartered Bank and UBA.

The $1.2Billion transaction, signed in September 2015, was projected to fund 36 wells with a projected peak incremental production of 41, 000 barrels of crude oil per day and 127Million standard cubic feet of gas per day (MMscf/d) “in the years ahead”, according to a statement by the Nigerian National Petroleum Corporation (NNPC), the senior partner in the NNPC/Chevron JV, of which Chevron is the operator.

16 of the 22 wells drilled so far are in the swamp, in the Gbokoda field in Oil Mining Lease (OML) 49 and were drilled by the rig OES Respect. The remaining six wells, drilled in shallow water, were drilled by Shelf Drilling’s Trident 8, on the Okan field, in OML 90.

It is not clear how much of the incremental production has been achieved by the activity. “The package is projected to generate between $2 and $5Billion of incremental revenues to the Nigerian government over the life of the project, subject to prevailing oil price in the upcoming years”, the NNPC statement had said.


Kenya: Three Wells Most Likely for the rest of 2017

By Sa’ad Bashir, East African Correspondent, in Dar es Salaam

It’s not clear if other companies, apart from Tullow and partners, will drill any more wells in Kenya in 2017. But Tullow and its JV partners have confirmed that three wells are planned. Drilling is underway in one of them, to test an undrilled fault block adjacent to the Ekales field.

The Ngamia-11 appraisal well will be drilled and completed for use in an extended water flood pilot test in conjunction with the Early Oil Pilot Scheme (EOPS) and the Etete exploration well is planned to test a prospect adjacent to the Greater Etom structure.

Tullow says that further locations are currently under evaluation to be added to the programme.

Water injection testing on the Amosing and Ngamia fields has been successfully demonstrated and underpins the feasibility of water injection for the development of these fields.

Africa Oil Corp. has a 25% working interest in Blocks 10BB and 13T with Tullow Oil plc (50% and Operator) and Maersk Olieog Gas A/S (25%) holding the remaining interests.


Ghana Expects a Surge in Rig Activity from early 2018

Ghana’s leading E&P operators hope be busier with the drill bit between late 2017 and mid 2018 than they currently are. Rig activity will be at their peak by 1Q 2018.

Activities at three oilfield developments will be responsible for the increase in rig count.

Ghana’s crude oil production averaged 132,000BOPD in Q12017 and has moved higher in 2Q 2017.

OES Teamwork Rig Will Drill Opuama 7 Sidetrack

By McJohnTatsi, in Warri

The NPDC/Elcrest joint venture has awarded OES Energy Services Limited the contract to drill a sidetrack well to Opuama-7. The drilling contractor will utilise its OES Teamwork swamp rig for the work.

The side-tracking of the existing Opuama-7 well is expected to contribute an initial production rates of 5,900* barrels of oil per day (“BOPD”) gross, increasing near term overall production from OML 40 to around an expected 17,500 BOPD gross, says Eland Oil and Gas, the UK listed technical partner in the Eland-Starcrest IJV (otherwise known as Elcrest).

OES Teamwork swamp rig is currently undergoing meticulous preparation, which includes mobilising rig personnel, system tests and equipment shake down, to target the commencement of the rig move to Opuama-7 location in July 2017”, the company explains.

Duration
The rig will drill a sidetrack to around 2,300metres (7,500feet), expected to take in the region of a month to complete.

Extension Possible
As part of the contract’s terms, the NPDC/Elcrest Joint Venture has the option to extend the contract for the re-entry of Gbetiokun-1, which it intends to start immediately after Opuama-7 sidetrack.


Ophir Drills the Seventh Duster in Short Order

By Toyin Akinosho, Publisher

With the Ayame-1X exploration well in Cote D’Ivoire’s Block 513 announced as a dry hole, Ophir Energy, the London listed explorer, has concluded the seventh dry hole in Subsaharan Africa in the space of three years.

Of this number, six of those dusters were drilled in one year; 2014.

Ophir had not drilled any new field wildcat well in Africa since it plugged and abandoned the Mkuki-1 well offshore Tanzania in November 2014.

Ophir drilled three dry holes in Gabon and three dry holes in Tanzania in 2014 and then stopped drilling new field wildcats as an operator on the continent altogether.

But as a non- operating partner, Ophir has been involved in successful wildcats in the same time frame, notably with BG as operator, offshore Tanzania.

It has also been lucky in Equatorial Guinea, where it is developing a gas field.
But its record for drilling dry holes in the subcontinent is unparalleled by any other independent.

A fuller story of the company’s long dry season, complete with details of the wells drilled, is published here.


Tembo Appraisal Waits On Farm in Partner

By Sa’ad Bashir, East Africa Correspondent

Wentworth Resources says that the drilling of an appraisal well on the Tembo structure depends on its finding a farm in partner to bear the cost.

The AIM and Oslo listed explorer made a gas discovery, Tembo 1, in cretaceous sands in the 2,500 km2 Tembo Block, onshore Mozambique, in December 2014 and an oil and gas bearing show in a deeper reservoir. Wentworth is hoping to encounter oil in a down dip, thicker section of that deeper reservoir.

With 85% operatorship, it has been hoping to farm down.

“The Company is now working on advancing a farm-out process with a view to securing an industry partner to jointly drill an appraisal well in 2018”, Wentworth says in a release.

Wentworth is working on 1,000 km of existing seismic data is complete, interpretation is being finalized and results from the Tembo-1 discovery well have been fully analyzed. We will update the market as material developments on this asset occur.


Chinese Rig To Drill Ororo-2

Sirius Petroleum will be drilling Ororo-2, a step out from the Ororo-1 well, with the services of COSL Drilling Europe AS, a subsidiary to China Oilfield Services Limited, (COSL) Beijing, China.

The contract is for a multi-well campaign that begins with Ororo-2, before June 2017.

The well management activities for the duration of the contract will be carried out by the Norway headquartered oil service firm ADD Energy, which claims, on its website, that it “was instrumental in working with Sirius to secure the drilling contract with COSL Drilling Pan-Pacific Limited”.

Part of what clinched the contract for ADD Energy was that it agreed “to extend delayed invoice and payment terms to Sirius in line with the Company’s other project partners.

The contract envisages a drilling programme on the Ororo Field and can be expanded to include other potential offshore assets.”

The other contractor or ‘project partner’ on the campaign-as Sirius describes them- is Schlumberger, which will provide Sirius with a comprehensive package of managed and integrated products and services including directional drilling services, logging, completion and production fluids, cementing and pumping services, well intervention and stimulation products and services, well testing services, wellsite communications and data and software solutions.

The main objective is to drill two to three wells that will lead to first oil in Ororo field, one of the 24 marginal fields awarded to 31 Nigerian companies by the Nigerian government in 2003.


Ntorya-2 Scopes Updip of the Discovery Well

The Aminex operated appraisal well Ntorya-2 onshore Tanzania is targeting the same channel complex as the Ntorya 1 discovery, but is being drilled further updip of the reservoir.

The well location, in the Ruvuma Basin,  is a 1,500-metre step-out from Ntorya-1 and is prognosed to drill to an estimated total depth of 2860 metres.

TOTAL Returns to the “Cape of Storms” in late 2017

By Toyin Akinosho
TOTAL will return to drilling in the ‘Cape Of Storms’ in late 2017, a full year and several months after the original planned date.

The French major halted drilling in Block 11B/12B in South Africa’s offshore Outeniqua Basin in November 2014 because of mechanical problems on the rig, caused by the challenging environment in the Agulhas, with its chaotic combination of currents, waves and winds, which contrasts sharply with the mild metocean conditions of the West African deepwater.

“There’s only a small window in the year that we can drill in this part of the continent”, a ranking TOTAL earth science executive said on the side of the Africa Oil Week in Cape Town, South Africa. “The place is quite turbulent.”

Asked to comment on TOTAL’s programe for its South African operations, Guy Maurice, the company’s senior Vice President E&P Africa responded in the negative: “No, I don’t want to make any declarations today”. It was he (Maurice) who announced a halt to drilling of the Outeniqa well at the same conference in October 2014.

South Africa is not anywhere high on TOTAL’s upstream ranking, at least for 2017. Mr. Maurice’s conference presentation included activity in Angola, Nigeria, even Cote d’Ivoire. He gave a date for Final Investment Decision on its planned field development in Uganda, but South Africa was clearly missing.


Aminex Moves Caroil-2 to Ntorya-2

Prospect significant for extending the Ruvuma play onshore

London listed Aminex has moved a drilling rig towards the Ntorya-2 appraisal well in the Ruvuma basin PSA located largely onshore in southern Tanzania.
The Caroil 2 drilling rig is likely to spud the much anticipated well before the end of October 2016.
The contract, executed with Caroil, the French driller, is for one firm well with an option for a second well.
Aminex has a 75% working interest and is the operator of this well, which is positioned approximately 1500m southwest of the Ntorya-1 discovery well, which flow tested at 20 MMscf/d with 139Barrels associated condensate in April 2012.
The appraisal, coming four and half years after the discovery, a period in which Tullow Oil exited the asset, is indicative of the challenges of resource volume.
But Ntorya is significant for one thing: it has successfully extended onshore the Ruvuma Basin fairway which has been proven in deepwater Tanzania and Mozambique as containing over 130 Trillion cubic feet of gas.
