Silverwell Technology, a global developer of digitally intelligent gas lift production optimisation systems and services, has celebrated a step forward in permeating the African market after securing a contract from a major operator offshore Nigeria.
The contract will see Silverwell bring its digitally intelligent artificial lift (DIAL) gas lift production optimisation system to the country. This system integrated in-well monitoring and control of gas-lift well performance with surface analytics and automation to continually optimise production, remotely and without well intervention. This is expected to bring significant benefits to the operator with DIAL reportedly enhancing the net present value (NPV) of each well by up to US$50mn over their lifetime.
According to Silverwell, DIAL is used by operators around the world for onshore and offshore applications. Currently, it is being installed in shallow water oil wells in the Gulf of Guinea and is operated from an unmanned production platform.
“The key driver for the operator was the OPEX saving related to well intervention and the associated logistical cost. The DIAL system also enables the ability to ensure continuous and remote well monitoring and production optimization,” remarked Stephen Faux, General Manager of Operations for the Eastern Hemisphere. “Conventional gas lift systems would require identification of the optimisation issue, data analysis, vessel mobilisation, and ceasing production to perform well intervention to change the gas lift valve(s).
“This process, from start to finish, can take several months and incurs significant financial impact. With DIAL, all data is delivered in real time to the engineer’s desk allowing them to perform analysis, identify uplift opportunities, and make changes to the configuration without visiting the platform. Petroleum engineers can improve production uplift in minutes.”
Silverwell noted that with the system cutting well lifecycle costs by eliminating well intervention, avoiding deferred production and substantially reducing logistics expenditure, it could bring significant benefits to West Africa. And, in doing so, the company expects this contract to lead to further adoption of DIAL in West Africa and across the continent.
Darrell Johnson, Silverwell CEO, said, “Entering the African market and successfully delivering our first project there is a major milestone for Silverwell, as recognition of DIAL’s benefits to operators continues to gather momentum globally.
“Opening up this latest frontier for our industry-leading technology provides a platform for further expansion in West Africa and the wider continent. We see significant potential for DIAL in Africa and elsewhere. From North America to the Middle East, Asia Pacific, and now Africa, demand for a proven method to reduce operational expenditure while maximizing asset productivity is growing. We’re excited for the next steps in DIAL’s journey toward adoption by operators in every region.”
Toshiba Energy Systems & Solutions Corporation (Toshiba ESS) will be supplying SEPCOIII Electric Power Construction Co., Ltd. with steam turbines and generators for the geothermal power plant equipment renovation of Units 1 through 3 at the 45MW Olkaria I geothermal power plant in Kenya.
The equipment will be shipped to the site by December 2025.
Said to be the oldest geothermal power plant in Kenya, Olkaria I has been in commercial operation by the Kenya Electricity Generating Company PLC (KenGen) since 1981.
The installation of the new steam turbines and generators will allow the units to achieve higher outputs with less steam, as each of them will increase considerably from 15MW to 21MW each. This will make a huge difference in meeting Kenya's growing demand for power. The development aligns with the Kenya Government's Vision 2030, which aims to boost the country's electricity generating capacity from renewable sources. Many new geothermal power plants are planned to tap into the 9GW geothermal potential in Kenya's Great Rift Valley region.
Toshiba ESS and KenGen are working closely since 2022 in providing operation and maintenance (O&M) services for geothermal power plants, and have plans to expand their service to developing countries beyond Kenya.
Shinya Fujitsuka, Director and Vice President of the Power Systems Division at Toshiba ESS, said, "I'm pleased that we can contribute to energy stability in Kenya by providing our equipment and services. Toshiba ESS will continue to provide optimal products and solutions to meet customer needs through its lineup of small to large geothermal steam turbines and generators with power outputs ranging from 1 MW to 200 MW. Aiming for the further clean energy indispensable for the realization of a sustainable society, we will contribute to the realization of a carbon neutral society by providing geothermal power plant services both in Japan and overseas."
The Offshore Well Intervention West Africa Webcast from Offshore Network shines the spotlight on a market with significant potential and unpicks the challenges holding it back.
Moderator Robert Daniels, Editor at Offshore Network, was joined by an expert panel of guests who joined the discussion from a myriad of locations across the region. This list of panellists willing to share their knowledge and experience included Obasi Isdore Chigozie, Well Intervention Specialist at Sterling Oil Exploration & Energy Production Co. Ltd; Albert Amewolah, Subsea Operations Engineering at Tullow Oil; and Isioma Agbadiba, Subsea Production Supervisor at Eni Nigeria.
At a time when the global oil and gas industry is grappling with the energy transition, the need to maintain production targets has remained imperative – despite COP28 calling for an eventual transition away from fossil fuels – in line with growing power demand. In West Africa, companies are now looking to do their part for the environment while also contending with the wider issues around electrification and the role fossil fuels will continue to play in the economic development of its nations.
It is against this backdrop that the panellists spoke on the role of offshore well intervention within this evolving environment – a method often depicted as the answer to enhancing production rates without incurring the sustainability hit of drilling new wells. Additionally, the market and its servers are receiving heightened attention due to the growing need for plug and abandonment activities as the world’s (and region’s) offshore wellstock increases in average age with every passing year.
Together, the industry experts explored such topics and answered where West Africa fits into this global trend? What are the factors unique to the region and that are shaping its future? And what must be done for more well intervention campaigns to be conducted there?

Thermoplastic composite pipe (TCP) provider Strohm has supplied TotalEnergies with a TCP jumper, which has been commissioned for a 1,600 m deepwater project in West Africa.
This installation has followed a rigorous testing programme, during which TotalEnergies qualified the Netherlands-based company's TCP jumper for permanent subsea applications. All pre-deployment inspections and tests were successfully passed, certifying it for its full life cycle on schedule.
The installation of Strohm’s 5.2” ID, 340 bar design pressure TCP Jumper in the Egina field was supported by a local Nigerian subsea services provider. The pipe’s lightweight properties allowed it to be transported by a small, multi-purpose vessel and installed by local contractors, greatly reducing carbon emissions and costs. Strohm personnel were mobilised offshore to assist in the installation process.
Martin van Onna, Strohm CEO, said, “We are immensely proud to see our first TCP Jumper for our highly valued client TotalEnergies installed and operational in West Africa. This success reaffirms TCP as an ideal deepwater solution and strengthens our leading position in the market.”
Strohm’s TCP provides a robust, corrosion free and field-proven solution for operators. TCP jumpers can be manufactured and shipped in long continuous lengths, stored onsite for long periods of time, cut to length when required and terminated within hours, with no change to its properties or lifespan. TCP for subsea jumpers as well as flowlines and risers have proven to reduce the CO2 footprint of pipeline infrastructures by more than 50%.
40 years since the launch of its first subsea test tree system, Expro, a leading energy services provider, has remained at the forefront of subsea landing string technology.
The first 10ksi subsea test tree assembly (SSTTA) was created for an exploration and appraisal well project for Hamilton Brothers in the North Sea in 1983. Several of its SSTTA technologies have been on a first to market basis and have helped to progress the sector’s capabilities over the years. Expro has now undertaken more than 3,000 subsea deployments in exploration and appraisal, completion, and intervention applications, and remains a global leader in large-bore SSTTA solutions.
Other subsea well access major milestones Expro has achieved over the years have included the introduction of the first 7 3/8” 10ksi horizontal tree completion landing string system; the launch of the industry’s first 6 ¾” high debris SSTTA system; the release of the first large bore 6 ¾” 10 ksi subsea electro hydraulic control system; unveiling the first 6 ¾” 10ksi dual bore and mono-bore subsea test tree offshore; revealing the first 15ksi 6 1/8” horizontal tree SSTTA and electro-hydraulic control system; and the development of 7 3/8” 10ksi high debris SSTTA.
The evolution of subsea test tree assemblies has allowed the company to expand into the open water well intervention market through the introduction of both riser-based and riser-less well intervention solutions. Such success and dedication to subsea well access application even earned the company the accolade of Intervention Champion of the Year at the recently-held OWI Global Awards 2023.
At the company is showing no signs of building on its successful history. In a bid to continue this history, it has sought to boost its subsea capabilities by acquiring PRT Offshore, the only company to offer a complete Hook-to-Hanger solution enabling comprehensive well completions, interventions, and decommissioning services from surface to subsea. The acquisition enables Expro to expand its portfolio of cost-effective, technology-enabled services in the North and Latin America region and accelerate the growth of PRT Offshore’s surface equipment offering into the Europe and sub-Saharan Africa and Asia Pacific regions.
“At Expro, we’ve been first to the market with many of our subsea test tree assembly products and, as future technical challenges arise, we believe that with our customer-bespoke solution philosophy, we’ll continue to be at the top of the subsea test tree application,” remarked Graham Cheyne, Expro’s Vice President of Subsea Well Access.
“From starting in 1983 supporting operators in the Norwegian North Sea, we’ve become a global player in all parts of the world, supplying fully integrated technologies and services from surface to seabed – the hook to hangar concept. The subsea test tree market operates in the full well lifecycle – from exploration and appraisal through to abandonment and decommissioning while continually looking to improve our delivery and operational performance, and service quality to our global client base.
"Whilst leading in this market for over 40 years with many first to market technologies we are committed to delivering the new technology requirements of tomorrow in order to meet our customer needs whilst maintaining the high level of service quality and customer care.”
