Expro well abandonment Balmoral Offshore Oil Gas

Expro has secured a new contract with Harbour Energy for a well abandonment campaign as part of the decommissioning project for the Balmoral area, in the UK Continental Shelf.

The contract, valued at more than US$20mn, will utilise Expro’s Subsea Well Access technology with a combination of open-water and in-riser applications deployed from a semi-submersible rig.

Expro’s ability to supply a lightweight open-water system will help to mitigate loading issues during the subsea well access intervention part of the overall abandonment campaign. The company’s open-water and in-riser bore selector technology, which eliminates the use of a dual bore riser for the entire abandonment campaign, is designed to deliver significantly reduced system deployment and retrieval times with lower maintenance costs.

To overcome key technical requirements from the customer, Expro devised an innovative technological solution based on a new build lightweight intervention system, incorporating its unique subsea ball valve technologies. Expro’s existing API 17G standard high debris ball valve was recently qualified to provide a single ball cut and seal on coil tubing. This ball valve technology will be re-packaged into bespoke open water riser housings to provide the lightweight solution required.

The solution developed for this award expands Expro’s subsea well access portfolio and allows Expro to now supply the client with all the subsea well access tooling required for the abandonment campaign on the Balmoral area, for horizontal and vertical Xmas Trees.

Colin Mackenzie, Expro’s Vice President of Europe and Sub-Saharan Africa, commented, “We are proud to have secured this award by offering an innovative approach to meet the needs of this important customer. We believe that our leading-edge technology continues to deliver safe, reliable and environmentally secure subsea well access in support of major projects around the world. We are delighted to further extend the scope of our partnership on this campaign which reinforces our position as a key enabler within the plug and abandonment market.”
