Valaris Limited has been awarded a two-year contract offshore West Africa for drillship VALARIS DS-10

The US$352mn contract is expected to commence late in the second quarter or in the third quarter 2026. The total contract value does not include the provision of additional services, but two unpriced options, each with a duration of one year.

More long-term contracts

President and chief executive officer, Anton Dibowitz, said, “This contract award is a testament to the safety and operational performance of VALARIS DS-10 and its crews, which have an excellent track record of successfully executing clients’ well programmes offshore West Africa. This contract increases our backlog by approximately US$350mn and supports our future earnings and cash flow, and we remain focused on securing additional attractive long-term contracts for our high-specification assets.” 

West Africa has seen enhanced rig activity, with Shelf Drilling and Borr Drilling also announcing contracts since late last year. 

Vitol has been one of the recent entrants to West Africa, acquiring interests worth approximately US$1.65bn. 

Norwegian seismic firm TGS has completed reprocessing work on data that it hopes will spur renewed interest in Angola’s forgotten deepwater Block 16

The company has announced that it had finished work on the Block 16 GeoStreamer MC3D seismic dataset in the Lower Congo Basin, in partnership with Agência Nacional de Petróleo, Gás e Biocombustíveis (ANPG).

Exploration in the deepwater Lower Congo Basin has experienced a resurgence in recent years, TGS reported, with numerous significant discoveries being made and rapidly brought on stream.

"This 3,684-sq-km rejuvenation project utilises modern depth processing workflows to deliver enhanced imaging beyond the original data, enabling detailed evaluation of deeper target plays in both post-salt and pre-salt sections,” it said in a statement.

Angola’s Block 16 has remained largely under explored since the early 2010s, however, with the most recent exploration well drilled in 2013. Until recently, publicly-known oil and gas discoveries within Block 16, in the latest dataset, were limited to the Bengo (1994) and Longa (1995) Upper Miocene finds in the northern section.

However, TGS said that a recent re-evaluation of wells in the Lower Congo Basin has identified oil recovery from Upper Miocene reservoirs in the southern part of the survey area. The survey also provides partial coverage of the field, a marginal field development opportunity currently being marketed by ANPG.

Discovered in 2003, Tchihumba contains hydrocarbon-bearing zones within Upper Miocene, Lower Miocene and Oligocene sands, with recoverable volumes estimated at approximately 136mn barrels.

Additionally, the Lumpembe-1 oil discovery on Block 15/06, drilled in 2023 and currently undergoing development studies, falls within the survey’s coverage.

“TGS is very pleased to continue our support of exploration in this region with our high-quality seismic data,” said David Hajovsky, executive vice president multi-client, TGS. “These accumulations, along with the proximity of significant neighbouring discoveries, present strong opportunities for future exploration success.”

Other West African projects TGS has completed recently include an enhancement of its Fusion 3D seismic dataset offshore Sierra Leone, focusing on the Vega prospect.

Recent discoveries in South America have intensified interest in this region, TGS stated late last year, positioning Sierra Leone as a promising new exploration frontier.

“With growing interest from international oil companies and independents, the Fusion 3D data comes at a crucial time.”

TGS also signed an agreement last year to enhance datasets in Mauritania with the Ministère du Pétrole, des Mines et de l’Énergie, strengthening its position as the sole provider of multi-client subsurface data in the country.

Sulzer has launched an energy efficiency and carbon reduction service called Sulzer Energy Optimisation Service to upgrade the standards of centrifugal pumps across their lifecycle for energy intensive industries such as power generation, oil and gas, chemicals and water desalination 

This service will address the growing demand for industrial energy efficiency with access to digital analysis, machine learning and ongoing monitoring to reduce carbon emissions, enhance reliability, and reduce energy costs. A 1% increase in global pump efficiency would save around 59TWh of electricity – equivalent to New Zealand’s annual power needs; some pumps’ efficiency could be increased by as much as 20-30%.

Ravin Pillay-Ramsamy, services division president at Sulzer said, “Inefficient and unreliable pumps cost operators in the industrial sectors millions of dollars in unnecessary downtime, energy costs and carbon emissions every year. Sulzer Energy Optimisation Service offers a comprehensive solution that tackles this inefficiency – from identification through to improvement and monitoring.

“A pilot customer in Spain will now save €1 million in energy costs and over 2,300 tonnes of carbon dioxide a year as a result of energy optimisation improvements identified by the Service. By rerating five pumps, energy efficiency increased from 72% to 83% saving the operator 5,000MWh in electricity every year.”

Consisting of four steps, an initial pump energy audit identifies areas of inefficiency with Sulzer’s proprietary calculator – PumpWise – outlining the potential energy, carbon and monetary savings.

A tailored proposal is generated by Sulzer’s expert team presenting a range of options to return the pump to run at its best efficiency point through an engineered retrofit, with varying techniques such as hydraulic re-rates, specialised coatings, wear clearances and more. Each option weighs operational costs, investment, downtime, payback and efficiency guarantees. The upgrades are then implemented with support from Sulzer’s established retrofit team which has delivered more than 4,000 retrofit projects globally since its setup in 2010. The team is supported by a network of more than 120 service locations globally.

Following retrofit, Sulzer offers a performance agreement to maintain optimised reliability and efficiency. This includes access to Blue Box, Sulzer’s proprietary machine learning technology which turns pump performance data into actionable insights.

Pillay-Ramsamy said, “For operators who are constantly challenged to do more with less, making energy efficiency improvements is a win-win. With pumps accounting for 20% of the world’s electricity demand, we want to offer a streamlined, futureproofed way for customers to improve their energy efficiency regardless of their pump OEM.

“To do so, we’ve combined the competence of our people and longstanding engineering expertise with our proprietary innovations and wrapped them in a collaborative and customer-centric approach. Altogether we believe this solution creates a new best practice standard for pump operation that goes above and beyond in supporting operators to remain future-ready.”

The 4000km-long Trans-Saharan Gas Pipeline (TSGP) will undergo a feasibility study update from international energy consultancy, Penspen, which will gauge the regional gas market in terms of economic and financial aspects to make a cost estimation

There will also be environmental and social evaluation, including legislation and consultation reviews, risk analysis, and development of scope of work for the front-end engineering design (FEED).

Jointly sponsored by the Nigerian National Petroleum Company (NNPC) Limited (Nigeria), SONATRACH (Algeria) and SONIDEP SA (Niger), the TSGP runs from Nigeria to Algeria. The project will be able to supply up to 30 bn cu/m of natural gas across West and North Africa annually, before it goes to European markets.

Arun Behl, Penspen’s sales and marketing director (Middle East & Africa) said, "The award of the feasibility study of this high-impact project underscores Penspen’s expertise in large-scale energy infrastructure development and our commitment to advancing strategic initiatives that drive economic growth and regional stability.

“We are proud to have been selected to support the next phase of this transformative project, leveraging our extensive experience in cross-country pipeline engineering and development to deliver a sustainable and efficient energy solution.” 

This will be a re-evaluation of the initial feasibility study, also conducted by Penspen, in 2006, following the project's initiation in 2002. Since then the pipe route has evolved to require an updated review in terms of current situations. Penspen is being supported inj its research work by fellow Sidara brand Dar. 

Besides the TSGP project, Penspen has been engaged in other mega pipelines initiatives, such as the Nigeria - Morocco Gas Pipeline (NMGP) among others. 

The Nigerian National Petroleum Company (NNPC) Ltd has restreamed the Port Harcourt Refining Company (PHRC), commencing crude oil processing from the plant for the delivery of petroleum products into the market

The NNPC group chief executive officer, Mele Kyari, announced the development, expressing his gratitude to all stakeholders involved, and marked the occasion as an era of energy independence and economic growth for the country.

Products delivered included premium motor spirit (PMS), automotive gas oil (AGO) and household kerosene (HHK), among others. 

The PHRC rehabilitation project, is an engineering, procurement, construction, installation and commissioning (EPCIC) project that is aimed at restoring the refinery to full functionality and renewal.

The East Africa Energy Cooperation Summit (EA-ECS), taking place 29-30 January in Arusha, Tanzania, will be uniting the region's energy independent poiwer producers (IPPs) and engineering, procurement, construction and financing contract (EPCF) stakeholders to discuss the region's investment potential and innovations taking place in the industry

The event will delve into the success stories, including the Ethiopia-Kenya electricity highway, highlighting the role of cross-border collaboration for economic and social development.

Led by Ministers from across the EAC and large-scale energy users, over two days, the Arusha Summit will deep dive into opportunities for the private sector, advocating for a diversified energy mix to maintain grid stability to support major industrial growth, as well as C&I generation.

“Energy is a pillar for development and growth and is crucial for the functioning of the economies of the EAC Partner States. The East Africa Energy Cooperation Summit will serve as the ideal platform for advancing projects and bringing tangible changes in the industry,” said Andrea Malueth, deputy secretary general (Infrastructure, Productive, Social & Political Sectors), East African Community Secretariat.

“Ten years from now, the EAC’s middle classes will have more job stability, more opportunities, and more disposable income than ever before. New railways, industries, ports, and tourism will position the region as the number one investment destination globally, taking the title back from both parts of Asia and Latin America,” said Elisa Palmioli, producer, EnergyNet, which is organising the event.
