Unity launches a new range of compact technologies

Aberdeen-headquartered Unity, Europe’s provider of well integrity solutions, has launched a new range of compact technologies to solve common industry challenges including working space, component weight, and personnel on board (POB) restrictions.  The technologies will be used to 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 POB, 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, which 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 2ft2, requiring only two technicians to operate. It delivers savings in the region of 60-75% for a single deployment.

Unity’s new dual-bore Xmas tree isolation system has a footprint of just 1.5ft2 with an operating height of only 6ft above the well cap. It can be mobilised and deployed rapidly for shallow plug settings, 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 2-3 hrs compared to 2-3 days for wireline or coiled tubing interventions and the system is quickly and easily moved between wells.
