Unity, one of Europe’s largest providers of well integrity solutions, has launched a new range of compact technologies to solve common industry challenges and support Unity’s surface well integrity, shallow intervention and well decommissioning services.
For offshore operations, the new products reduce well bay space requirements, simplify and accelerate offline mobilisation and reduce person on board, cost and risk. Due to these efficiencies, the products all offer between 50-75% savings in OPEX.
The new technology range includes a compact dual-bore xmas tree isolation system, a compact valve removal tool and a compact shear-seal valve. The products complement Unity’s existing Surface Intervention System (SIS), the first product in this compact technology range. It is already delivering multi-functional operations such as inspection, plug setting, milling and xmas tree removal, at reduced cost and improved efficiency compared to wireline or coiled tubing intervention. The SIS is the most compact of its type on the market with a footprint of around 2 sq ft, requiring only two technicians to operate.
The new dual-bore xmas tree isolation system has a footprint of just 1.5 sq ft with an operating height of only 6 ft above the well cap. It can be mobilised and deployed rapidly for shallow plug setting, particularly suited to support and reduce the cost of P&A operations. It can be deployed offline without the need for traditional intervention equipment, saving around 60-75% or more per well. Time savings from rig-up to rig-down are in the order of two to three hours compared to two to three days for wireline or coiled tubing interventions and the system is quickly and easily moved between wells.
The valve removal tool is also designed for use in cramped well bays and delivers an impressive, industry leading, 1,200 ft/lbs torque with optional hydraulic operation without the associated space normally required for such operations. Its rental price is around 60% lesser than similar products.
The new compact shear-seal valve is designed to reduce the weight and geometry of intervention pressure control equipment. It utilises a hydraulically actuated ram but is 50% lighter and 30% smaller than the next closest comparable product. It is rated to cut slickline, wireline, SIS rods and coiled tubing and is modular in design, allowing dual redundant stack-up configurations. Its compact size and reduced weight improve handling and help to reduce concerns over structural integrity on late-life assets.
Gary Smart, CEO at Unity said, “Unity is engaged in long term contract work on over 1,000 wells around Europe, the Middle East and Africa. Our investment in this new compact technology range has followed on the back of significant contract wins over the last 18 months, which have highlighted several common technical challenges faced by the industry, particularly in the late-life, P&A and well decommissioning market. We are very excited to be offering such an impressive step-change in savings and technical advancement to the market.”
D&A GOM 2022
Innovative technology for decommissioning and related operations will soon be on display at D&A GOM 2022, arriving in Houston, Texas, on 18 May. At this event, the offshore community is set to reunite face-to-face to discuss the challenges and opportunities marking decommissioning and abandonment in the region, listen to sessions delving into current complex situations and network to help each other optimise their strategies.
