Senegal: Cairn to Drain~400Million Barrels With 25 Wells

By Toyin Akinosho, Lagos

Cairn Energy and partners are considering an initial well count of approximately 25 wells for the first phase of development of the SNE field in deepwater Senegal.

The project is the first major oil development in the Northwest African margin.

The wells will be principally drilled in the field’s “S500 lower reservoirs”.

It is anticipated that other discoveries, e.g Fan South and SNE North, may be developed and tied to the SNE field development afterwards.
But all these considerations are at concept selection stage now and a clear decision is still a little far ahead.

“The development concept being considered by the joint venture is a standalone FPSO facility with subsea wells and infrastructure”, FAR Limited declares in a just released report. “The project will be designed to allow flexibility for anticipated subsequent development”.

Although FAR Ltd is a 15% non operating partner in the venture, it has been the more vocal with updates than operator Cairn Energy.

The joint venture aims to have all Government approvals in place by the end of 2018, with a target of first oil in 2021-2023.

The extensive SNE field with an area covering approximately 350km2 has been assessed by FAR to contain 640MMbbls on a full field basis (100% basis, best estimate, Contingent Resources, unrisked). This means less than 450MMbbls in terms of proven oil.
“In line with the terms of the Production Sharing Contract with the Government of Senegal, the joint venture has made a submission to evaluate the SNE North discovery and an application to evaluate the FAN South discovery is currently being compiled”, FAR explains in the note. “Both discoveries are in tie-back range of a hub development at SNE and, if the appraisal is successful, will be tied into the SNE development in later phases of development.

Conoil Breaks the Cretaceous Code in the Niger Delta

By Toyin Akinosho

The Nigerian junior, Conoil Producing, has encountered “possibly commercial sized” hydrocarbon footage in a cretaceous sequence in the Toju Ejanla-1 in Oil Mining Lease(OML) 103 in the western flank of the Niger Delta.

The well was drilled in a corner of the lease that is the boundary between the Niger Delta and the Benin Basin.

The company is using the Adriatic-1, a jack up rig operated by Shelf Drilling.

Discoveries have been made in two reservoirs but details are still sketchy as testing/sampling is still ongoing to know the extent of their materiality.

Conoil is not in a hurry to drill either an appraisal well or other prospects that are on trend with the Toju Ejanla structure, but would rather integrate the data into ongoing studies.

It is unusual to find hydrocarbon in the Cretaceous sequence of the Niger Delta, which is a tertiary basin. The North western flank of the Niger Delta, in which OML 103 is domiciled, is close to the boundary of the Benin Basin, whose sedimentary deposits are located in the cretaceous, an older geological sequence. Which begs the question as to whether this “discovery” is in the Benin Basin, or in the Niger Delta. Either way, if it is announced to be commercial, it would be a significant find.

GABON: BWOffshore Runs With The Dussafu Plan

By Toyin Akinosho

With proved reserves of 16MMBO, field is unlikely to deliver more than 6,000BOPD

BWOffshore spud the first of the two producer wells in the final lap to first oil in the Dussafu Acreage offshore South Gabon.

The Norwegian operator is angling for first oil from the field in the second half of 2018.

The DTM-2H production probe, on the Tortue oil field, in 116metre water depth, part of the Dussafu Marin Production Sharing Contract, is being drilled with the Borr Norve jack-up rig.

The Tortue field contains oil reserves in two main sandstone reservoirs – the Gamba and the Dentale D6.

DTM-2H is a horizontal well targeting the Dentale D6 reservoir at 3,140 metre true vertical depth (TVD) subsea. Following drilling, the well is intended to be completed as a gas lifted, subsea oil production well with an approximate 500 metre horizontal drain. The drilling and completion for DTM-2H is expected to take approximately 70 days. Following the drilling of the DTM-2H well the rig will move first to drill the DTM-3 pilot hole in order to appraise the northwest of the Tortue field in both the Gamba and Dentale reservoirs. Subsequently, the rig will drill the DTM 3-H production well targeting the Gamba reservoir at Tortue. The two production wells will be tied back to a leased floating production, storage and offloading (FPSO) vessel via subsea trees and flowlines.

The partners have not shared the likely production rates after the wells have been hooked up, but with proved reserves being 15.9Million barrels of oil, certified by NSAI, an industry authority on reserves calculation, the optimum outut should be around 6,000Barrels of oil per day.

Nigerian Indies: The Talented Tenth

By the Editorial Board of the Africa Oil+Gas Report

Africa’s growth as an industrial marketplace is going to be determined by its exceptional companies

To go by sheer volume of crude oil output, Aiteo and Eroton should undoubtedly be the leading indigenous Nigerian Independent companies to watch in the immediate term. Their gross daily production of around 90,000 and 60,000 barrels In Oil Mining leases (OMls) 29 and 18 respectively, for most of 2017, are underpinned by the reserves sizes of those assets. On a net basis, these volumes compare favourably with other Western independents focused on African resources, including such aggressive operators as Tullow Oil and growing stars like Kosmos Energy.

Chevron, Shell Pull Back From Africa

By Jackson Otiti

Chevron Corporation’s divestment of its stake in downstream South Africa, its biggest downstream operations on the continent, is the latest evidence of the American major’s cutback from Africa.

Chevron, and indeed Shell, are coming across as increasingly bearish about their African outlook, at a time when other majors, BP, TOTAL, ExxonMobil and the smallest of them, ENI, take more positions.

Shell has led the taking of over $10Billion by a coalition of partners (including ENI and TOTAL) from asset sale in Nigeria between 2010 and 2015. The AngloDutch major is in discussion with two companies over divestment in three more Nigerian blocks, as we speak.

While Chevron unloads its 75% interests in its South Africa assets as part of its three-year divestment goals announced in 2014, TOTAL’s signalling of taking over the same asset, even though unsuccessful, is symbolic of the French major’s increasing investment in Africa.

British major BP has taken vast swaths of deepwater territory in the North West African margin, notably Senegal and Mauritania. BP is growing portfolios in Egypt and Angola. TOTAL is leading the development of Uganda’s oil resources and has won operatorship in new assets in Angola.

The two largest oilfield developments to come on stream in Africa in 2018 are led by TOTAL. Egina in Nigeria and Kaombo in Angola will each drain at least 200,000BOPD of oil at peak production. The largest oilfield development to take financial sanction in 2018, is led by TOTAL. From around 2022, the development, in landlocked Uganda, will produce over 150,000BOPD.

ExxonMobil is in the process of signing a Petroleum agreement in Ghana. The world’s top supermajor led the charge into Mozambique for most of 2016 and 2017, taking blocks in the bidding round, purchasing stakes in ENI’s Area 4 and vying for stake in Anardako operated Area 1 in East Africa’s southernmost country.

ENI commissioned production from Zohr, Egypt’s largest gas field in December 2017. It is also operating the country’s largest gas production at Nooros field, which produces close to 1Billion cubic feet of gas per day. Nooros was put on stream less than two years ago.

Chevron and Shell, meanwhile, are growing quieter about Africa, which features more in their divestment portfolios than their growth plans.

Ghana, ExxonMobil Sign Petroleum Agreement Tomorrow

By Toyin Akinosho

The word’s top supermajor lands a position in the West African Transform margin

Ghanaian authorities will be signing a Petroleum Agreement with ExxonMobil on Thursday, January 18, 2018, in Accra, the country’s capital.

The event, scheduled to take place at the Kempiski Hotel in the city, is the culmination of discussions that began on April 30, 2015, when the then Minister of Petroleum and the Ghana National Petroleum Corporation (GNPC) entered into a Memorandum of Understanding (MoU) with the supermajor’s Ghanaian subsidiary: ExxonMobil Exploration and Production Ghana (Venture) Limited, for acquisition of Petroleum Exploration and Production rights over the Deepwater Cape Three Points (DWCTP) Block, located in ultra-deepwater zone of between 2,000 and 4000 metre water depths in the prolific Tano basin.

“Pursuant to the terms of the MoU, the parties agreed to negotiate in good faith a Petroleum Agreement, with exclusivity period of seven months”, the Ministry of Petroleum said.

The discussions, in the event, have gone on far beyond the seven month exclusivity period and ExxonMobil has managed to get the Ministry’s nod, in large part because Ghana desperately feels that the presence of such a super major in its petroleum industry validates the country’s hydrocarbon potential. “Ghana is one of a few African oil producer countries without the presence of a super major”, the Ministry of Petroleum declares, welcoming the entrance of ExxonMobil.

The DWCTP Block has twice been relinquished in the past: by Vanco Energy (which became Pan Atlantic) and Lukoil, the Russian explorer. “It is one of the ultra-deepwater blocks which severely test the limits of modern technology and would take Research and Development to optimally develop and exploit any discovered resources”, said a newspaper advertisement by the Petroleum ministry.

ExxonMobil has been trying to get into Ghana for close to a decade, since the Anadarko/Kosmos Energy partnership discovered the Mahogany field in 2007 and established Ghana’s place on the hydrocarbon map of the globe. Indeed, the company and the country clashed in the early 2010s, as ExxonMobil worked on the possible purchase of Kosmos Energy’s portfolio in the country. Ghanaian authorities protested about being left out of the discussion and accused Kosmos of handing over the country’s exploration data to a third party without going through proper procedure.

Is Enhanced Oil Recovery the Future of Angola’s Oil Production?

Interview of Geraldo Ramos, Senior Production Engineer, Sonangol EP

Production decline in mature fields is a common challenge to offshore operators throughout the globe. And in West Africa especially, where developing new fields often requires delving into unexplored deepwater and ultra-deepwater territories, many have decided to take advantage of developments in enhanced oil recovery technologies to make the most out of their existing assets.

Sonangol EP is one of those companies who, despite recent positive discoveries in its offshore pre-salt acreage which should comfortably allow Angola to maintain its status as Africa’s second largest oil producer, sees the need to ensure additional reserves are extracted from existing wells.

Today, we speak with Geraldo Ramos, Senior Production Engineer at Sonangol EP who is currently undertaking a PhD at the University of Aberdeen focusing on Advanced Enhanced Oil Recovery techniques with specific focus on Angolan onshore/offshore fields. We discuss his results so far, his vision for Angola’s 2018 production landscape and the experience he gained from the North Sea.

Fired: José Filomeno dos Santos

Angolan President, João Lourenço, dismissed José Filomeno dos Santos as chairman of the Board of Directors of the Angola Sovereign Fund on Wednesday, January 10, 2018.

He immediately installed Carlos Alberto Lopes to the post. It was the second time in two months that the new President, elected last September, would fire a child of his predecessor, José Eduardo dos Santos, from a high ranking public position. Last November, Lourenço sacked Isabel dos Santos as head of Sonangol, the country’s state hydrocarbon company.
