Halliburton has launched the XTR CS injection system, a wireline-retrievable safety valve solution engineered for CO₂ injection in carbon capture, utilisation, and storage (CCUS) wells

Operators face unique challenges in CCUS environments, including ultra-low temperatures and the need for reliable flowback prevention. The system addresses these challenges with a depth-insensitive design that can be installed at any point in the wellbore, delivering reliable performance with high injection rates and smooth flow. This eliminates concerns about hydraulic fluid mobility and reduces planning complexity.

The system can be used as a primary or contingency safety valve or as a deep-set reservoir fluid-flowback prevention device. Unlike traditional surface-controlled wireline valves, the XTR injection system’s non-elastomeric design helps minimise leak paths and eliminate reliance on hydraulic operation systems. This system remains at steady performance at any setting depth, to simplify operations and inventory management.

A large flow area, combined with low opening pressure, promotes smooth flow and supports high injection rates with minimal pressure drop. The proprietary anti-throttling mechanism helps keep the valve fully open during injection, reducing wear and extending service life. The self-cleaning design incorporates integrated bypass ports and optimised poppet geometry to minimise debris buildup and erosion. For added flexibility, wireline retrievability allows easy retrieval and replacement, supporting contingency planning when needed.

The valve features an anti-chatter mechanism to extend service life while meeting API 14A standards for safety and compliance.

The rigorous CS qualification programme ensures the system’s operational integrity and ability to withstand harsh CCUS environments.

The injection system can be tailored for specific injection media and fluid properties, offering low opening force, minimal pressure drop, and a wide range of injection rates. To extend operational life, high-velocity flow is directed away from seal areas, and a novel anti-throttle feature reduces valve wear, maximising system reliability.

Maxime Coffin, vice president, Halliburton Completion Tools said, “The XTR CS injection system expands Halliburton’s Completion Tools technology leadership in low-carbon technology solutions, allowing operators to maximise CCUS well performance. This technology helps ensure reliability and flexibility in harsh environments, allowing operators to inject CO₂ efficiently and safely.”

The global oil and gas robotics market is forecast to grow from US$90.2bn in 2024 to US$205.5bn in 2030, according to data analytics and consulting company GlobalData

Robotics is rapidly transforming oil and gas operations as advances in artificial intelligence (AI) and cloud computing unlock the next phase of industrial automation. Previously focused on repetitive industrial tasks, robots can now operate autonomously, collaborate, and access cloud-based data in real time. AI enables advanced decision-making, navigation in complex environments, and reduced reliance on human intervention.

Despite progress in humanoid robotics, task-specific robots remain dominant. GlobalData’s Strategic Intelligence report, “Robotics in Oil and Gas,” highlights how robotics is increasingly being adopted across the oil and gas value chain to improve safety, efficiency, and asset integrity.

Operators such as Equinor deploy subsea autonomous vehicles, including Hydrone-R, for extended underwater inspections, while Shell uses Cyberhawk drones and Sensabot robots for aerial and ground-based inspection of flare stacks, tanks, and pipelines. BP and Chevron have trialled Spot quadruped robots to autonomously survey facilities and collect visual, thermal, and methane data, reducing personnel exposure to hazardous environments. While ADNOC deploys more than 65 robotics applications across its operations.

Ravindra Puranik, Oil and Gas Analyst at GlobalData, comments: “Autonomous robotic systems are being introduced across hazardous, remote, and offshore environments to perform inspection, surveillance, and monitoring tasks without continuous human control.”

These platforms deliver higher operational efficiency through faster inspection cycles, consistent task execution, and repeatable, high-quality data capture, independent of operator skill or availability.

GlobalData notes that offshore and subsea operations remain a major focus area for robotics deployment. Remotely operated vehicles (ROVs) continue to support real-time subsea inspection, maintenance, and intervention, while autonomous underwater vehicles enable long-duration seabed surveys and pipeline monitoring with reduced reliance on surface vessels.

Puranik concludes: “While challenges remain, the integration of robotics with digital twins, edge intelligence, and predictive analytics is accelerating. As these technologies mature, robotics will move beyond supporting roles to become indispensable operational assets, across the oil and gas industry.”

Energy services provider Expro has launched Solus – a high-debris single shear and seal ball valve system for subsea well access

Solus replaces the conventional requirement for two valves with just one, reducing operational risk and complexity while accelerating the drive toward more cost-efficient subsea intervention technologies.

Tested and validated in accordance with API Std 17G, Solus is the first fully NACE MR0175 compliant fail-close bi-directional high-debris ball valve system that can shear and seal on wire and coiled tubing. It can be used in both in riser and open water applications across the entire well lifecycle - from exploration and appraisal and completion intervention to plug and abandonment (P&A) and decommissioning.

Solus has already been deployed for a new in-riser completions development in the Gulf of America and installed in an open water system for a North Sea P&A campaign. The system provides shear and post-shear seal for gas and liquids on slick line, braided electrical cable, and coiled tubing. It delivers bi-directional sealing for liquids and gas, even after a pump-through.

Solus has also been included in the Expro lightweight P&A Open Water Intervention Riser System (OWIRS).

Solus’ modular and compact design is an additional attraction, while its fail-close design reduces risk of emissions and provides a unique well safety barrier. It offers superior high debris (HD) flexibility for a wider range of complete well lifecycle challenges, with 15% solids ingress qualification size.

Daniel More, vice president Subsea Well Access, said, “In introducing Solus, Expro now offers the subsea engineering market a distinctive new system that provides the ultimate integrated shear and seal on coiled tubing and wire using just a single valve. Solus cuts through operational complexity. Simple to use, flexible, with a compact design for smaller BOP stack sizes, this is the latest in fail-safe technology developed by the experts of valve technology and systems integration.

“When there’s no room for error, Solus is designed to provide the assurance of an independent well safety barrier, combined with the surety and confidence that comes from Expro’s integration experience and expertise at the ‘whole system’ level. It’s the latest example of Expro’s engineering excellence and deep understanding of customer needs to move our industry forward.”

Solus is available in Expro’s ELSA landing string assemblies equipment offering. It is available in-riser as a single valve, a single valve with a latch mechanism, or within a subsea test tree, and within an OWIRS.

DUG is primed to power the next wave of discovery in the Middle East. (Image source: DUG)

Across the Middle East, oil and gas operators are acquiring larger, denser and more complex seismic datasets to unlock increasingly subtle geological targets

But as data volumes grow into the hundreds of billions of traces, the real challenge is no longer just acquisition. It is how quickly and confidently those datasets can be turned into actionable insight.

When growing data volumes are coupled with modern processing and imaging algorithms, such as elastic multi-parameter full waveform inversion, and the continued rise of artificial intelligence (AI) based workflows, the result is that high performance computing (HPC) systems are being pushed harder than ever. This of course intensifies demands on power, cooling and scalability. For energy giants, a key challenge is ensuring their HPC infrastructure remains fit-for-purpose to keep pace with modern geoscience.

Global technology company DUG is known for its state-of-the-art software and its network of some of the largest supercomputers on Earth. Against a constantly evolving hardware landscape, the Australian-born company is keeping its edge with the deployment of 82 new NVIDIA H200 machines, adding 41 petaflops of compute power to its global data-centre capacity. Each machine delivers an order-of-magnitude performance uplift over DUG’s fastest CPU-only hardware, further reducing the company’s turnaround times across both testing and production workflows.

The operational realities of a modern HPC facility also present significant opportunities for reducing both cost and environmental footprint. One way that DUG has maximised the energy efficiency of its HPC ecosystem is through the use of immersion cooling – where servers are submerged directly into a fluid that removes heat far more effectively than air. The technology supports significantly higher compute density, reduces power consumption and creates a stable environment without hot spots, dust or oxidation. Immersion allows operation at higher temperatures compared to air-cooling, thereby also reducing reliance on evaporative cooling, allowing hybrid or dry-cooling configurations that lower water use. This ultimately makes efficiency and sustainability part of the same design.

“Our data-centre upgrade significantly increases our total compute power,” said Harry McHugh, chief information officer at DUG. “This translates to even faster delivery of huge datasets and more computationally intensive workloads, from AI-inference applications, to advanced seismic processing and imaging workflows, including our revolutionary DUG Elastic MP-FWI Imaging technology”,

“Designing and operating at this scale gives us intimate knowledge of what modern HPC demands in practice – and this expertise drives the solutions we build and operate for our clients.”

With its new Abu Dhabi office supporting large-scale projects across the region, and a technology stack built around energy-efficient HPC and advanced imaging algorithms, DUG is primed to power the next wave of discovery in the Middle East, delivering faster, clearer and more reliable subsurface insights.
