Exploration

Oil and gas exploration company, Eco (Atlantic) Oil & Gas Ltd's subsidiary Azinam South Africa Limited will farm-in into Block 1 offshore South Africa Orange Basin 

With a 75% acquisition of the block from Tosaco Energy, Eco will become operator of a new Exploration Right. 

The remaining 25% will be transfered by Tosaco to a newly formed South African entity with a broad-based black economic empowerment (B-BBEE) rating, OrangeBasin Oil and Gas (Proprietary) Limited.

From Mopane to Venus wells, Block 1 is surrounded by rich discoveries. In March, Sintana Energy reported the third consecutive discovery of light oil in the Mopane complex

A triangular-shaped block in the Orange Basin, Block 1 runs along Namibia and South Africa by an area of 19,929 sq km. The eastern side of the block is approximately 174 km off the South African shoreline, reaching out some 263 km west into deepwater in the Orange Basin. 

Over the next three years, Eco, along with its in-house exploration team, will complete the interpretation and analysis of the already acquired 2D and 3D seismic data from the block. 

Strategic play

On the other hand, following the AJ-1 oil discovery post Gazania-1 drilling in 2022, the company has submitted all the documentation and environmental audits to the Petroleum Agency of South Africa to give up 50% of working interest offshore Block 2B in South Africa. Early this year, Eco transferred some of its interests in Block 3B/4B to Africa Oil Corp as well.

Colin Kinley, co-founder and chief operating officer of Eco Atlantic, said, "The Orange Basin continues to prove to be one of the newest and most prolific plays in the world and is running similar statistics to our Guyana play. Following completion of this farm-in, Eco will have one of the largest blocks in the entire Orange Basin. This is a strategic play for Eco that we have worked on over the past year, focusing on both oil and gas potential, and where we believe there are significant near-shore prospective gas resources. There are inboard gas discoveries on the block, Kudu to the North, and multiple discoveries in the Ibhubesi field to the South. With the reach of the block some 250km out into the Atlantic, this puts the West end of the Block into highly prospective opportunities for oil being just South and on trend with Shell's Graff discovery and Galp's Mopane discoveries, and North of our 3B/4B Block oil targets recently farmed out to TotalEnergies and QatarEnergy."

Geology & Geophysics

Energy data and intelligence provider TGS has collaborated with the National Oil Company of Liberia (NOCAL) to expand data access offshore Liberia

TGS will work to rejuvenate the existing legacy 2D and 3D datasets in Liberia's prospective Liberia and Harper Basins, aspiring to reach high subsurface clarity. 

This will help build a unified velocity model in depth, utilising cutting-edge imaging algorithms to produce the final migrated seismic data, which can prove crucial for prospectivity studies in Liberia's offshores.

The company has initiated this campaign since 2022, after the Liberia Petroleum Regulatory Authority (LPRA), in cooperation with NOCAL, opened direct exploration licensing negotiations for all offshore blocks over the Harper and Liberia basins in 2021. An already reprocessed 2D legacy seismic of approximately 12,097 kms is available for industry licensing.

Benefitting exploration

"At TGS, we are proud of our longstanding and successful partnership with Liberia, which we believe presents considerable offshore hydrocarbon opportunities. This high-quality 2D seismic data will be essential in promoting future licensing rounds offshore Liberia under a direct negotiation approach. It also allows E&P companies to further evaluate exploration opportunities in an under-explored but proven petroleum system adjacent to prolific hydrocarbon provinces," said David Hajovsky, executive vice-president of global multi-client at TGS.

Since Liberia's Petroleum Law came into effect in 2019, investment conditions were relaxed and more time frame for exploration was allowed. The reprocessed products by TGS add to the exploration prospects in the region with its consistent, continuous data set of several vintages, providing uninterrupted seismic attributes of higher confidence at target levels across the entire margin.

TGS has now taken on to the second phase to reprocess an additional 12,675 line kms over the Liberia and Harper Basins, bringing the total to over 24,700 kms.

Additionally, the company plans to reprocess approximately 15,616 sq kms of legacy 3D seismic data in the Liberia Basin.

Technology

Viridien (formerly CGG) will be conducting seismic imaging for a project in eastern Algeria by Groupement Berkine -- a joint venture between Sonatrach and Occidental Petroleum, among other global partners 

CGG is supporting majors such as bp in subsurface digital strategies since they signed a multi-year global data transformation and curation agreement in 2022.

This imaging campaign will cover an area of 3,400 sq km, capturing high-density onshore data set over blocks B404a and B208 of the Berkine Basin. It will involve a team of scientists from Viridien, who will work out of the company's advanced subsurface imaging centre in France.  

Delivering new subsurface insight

The team will draw on their experience of imaging similar large and ultra-dense land seismic surveys in the Middle East to apply an advanced imaging workflow to this project's dataset, and deliver new subsurface insight. They will also work towards polishing the resolution of the target area’s thin and faulted geology. 

Peter Whiting, executive vice president - geoscience, Viridien, said, “Viridien has been selected to conduct this high-profile project in recognition of its ongoing development of best-in-class imaging technology and significant high-performance computing capabilities. This, together with our long track record in Algeria, dating back to the 1950s, in-depth geological knowledge of the Hassi Messaoud Basin, and recent successful completion of a series of reimaging projects in the country, makes Viridien the preferred partner for delivering the best-possible subsurface images for critical field development decisions.” 

Last year, CGG's sensing and monitoring wing Sercel deployed its systems for a 3D mega-crew project in harsh terrain and desert conditions in North Africa.

The floating production storage and offloading (FPSO) vessel, a key component of the Greater Tortue Ahmeyim (GTA) Phase 1 LNG development, has arrived at its final location offshore on the maritime border of Mauritania and Senegal

The FPSO vessel is currently being moored at the site 40km offshore in a water depth of 120m. It will be operated by bp, on behalf of the project’s partners: bp, Kosmos Energy, PETROSEN and SMH. The project will produce gas from reservoirs in deep water, approximately 120km offshore, through a subsea system.

Following completion of its construction at the COSCO Qidong Shipyard, China, the FPSO has travelled more than 12,000 nautical miles to the GTA site.

“bp is investing in today’s energy system - and tomorrow’s too, and GTA Phase 1 represents this investment in action,” said Dave Campbell, bp’s senior vice president, Mauritania and Senegal.

“And this is a huge landmark step for the project, an innovative LNG development that is leading the way in unlocking gas resources for Mauritania and Senegal. The FPSO vessel has travelled halfway around the globe and its safe arrival and installation is testament to the resilience, skills, teamwork and huge effort of all the partners involved. We are now entirely focused on safe completion of the project as we continue to work towards first gas.”

The GTA Phase 1 development is expected to produce around 2.3 million tonnes of LNG annually for more than 20 years. It is the first gas development in this new basin offshore Mauritania and Senegal. With wells located in water depths of up to 2,850m, the GTA Phase 1 development has the deepest subsea infrastructure in Africa. The multibillion-dollar investment has been granted the status of National Project of Strategic Importance by the Presidents of both Mauritania and Senegal.

The FPSO will have up to 140 people on board during normal operation. With an area equivalent to two football fields and 10-storeys in height, the FPSO is made of more than 81,000 tonnes of steel, 37,000m of pipe spools and 1.52 million meters of cable.

The FPSO is expected to process over 500 million standard cubic feet of gas per day. It will remove water, condensate and impurities from the gas before transferring it via pipeline to the Floating Liquified Natural Gas (FLNG) vessel at the Hub Terminal approximately 10km offshore. At the FLNG vessel, the gas will be cryogenically cooled, liquefied and stored before being transferred to LNG carriers for export, while some is allocated to help meet growing demand in the two host countries.
