Energy services provider Expro has landed a significant milestone with the 100th deployment of its cementation technology SeaCure; this time for a five-well subsea batch campaign in Australia.
An exclusive offering on cementing portfolio, SeaCure technology was originally developed by DeltaTek, which Expro acquired last year. While the acquisition widened Expro’s technology portfolio in the well construction cementing sector, it also unlocked global access for DeltaTek. Recently, Expro completed the acquisition of integrity and intervention specialist, Coretrax, as well.
SeaCure helped maintain the quality primary cementation of the conductors, eliminating major risks associated with cement slurry placement.
A proprietary stabbed-in inner string technique was involved in post-cementing circulation via the inner annulus until slurry curing was complete. This ensured reliable installation of the top holes.
Alistair Geddes, Expro’s Chief Operating Officer, said, "Reaching our 100th global SeaCure job is a testament to the dedication and expertise of our team, as well as the strength of our technology and solutions. We are proud of providing the platform for Tristam Horn and the legacy DeltaTek to expedite their growth journey and quest for providing innovative solutions to our clients.
“Ineffective cementation is one of the single biggest contributors to cost over-runs, poor life of well integrity and ultimate failure of well objectives. Expro’s robust Cure portfolio has been developed to solve many of the issues associated with cementing subsea wells with the aim of delivering first time ultimate cement placement. SeaCure is an example of Expro’s commitment to investing in innovation, developing new technologies and delivering value and excellence to our clients globally."

Sea1 Offshore is the new name of the international offshore and subsea shipping company following a general meeting held earlier in May.
The formal decision was made in the wake of Kristian Siem’s withdrawal and will be accompanied by a new company logo. The company stated that crew and expertise will be transferred to the new company, even if nine of the company's vessels are taken over by Kristian Siem as part of the transaction.
Apart from this, the company has assured, it will be business as usual, although Bernt Omdal, CEO of Sea1 Offshore, has his eyes set on further growth.
“A more unified ownership structure will help to set a clearer course for the company,” Omdal explained. “We continue to operate all the vessels in our fleet, including the nine that are now owned by Siem. But we have changed the name and are replacing the logos at our offices in Brazil, Australia and Canada, and at the head office in Kristiansand.
“We are witnessing the start of a new upswing,” he continued. “We consider strengthening our fleet with several new construction vessels in order to take a larger part of the market in the offshore energy sector.”
James Fisher Decommissioning, part of James Fisher and Sons plc, has completed a significant decommissioning project in the Gulf of Thailand.
After extending the contract with a major offshore engineering, preparations, removal and disposal (EPRD) operator, the project became the largest to date for James Fisher, involving the removal of 25 offshore jackets in support of the client’s wider asset end-of-life campaign.
James Fisher was able to support the client through the expertise of its in-house decommissioning team and equipment, including abrasive waterjet cutting, hydraulic demolition shears and diamond wire saws.
To complete the multi-million-pound project, the decommissioning specialist utilised abrasive cut verification technology which ensured operations are completed successfully on the first attempt and without the need to re-evaluate the initial cut. It is estimated that, by improving efficiency of the operations in this way, cutting time was reduced by 50%.
“We pride ourselves on providing bespoke, environmentally focused solutions to overcome some of the most complex decommissioning structures faced by our customers,” Mark Stephen, Decommissioning Director for James Fisher, remarked. “This type of operation was a first for James Fisher Decommissioning in terms of jacket removal volume and duration, and we are extremely proud to have been part of the project. Utilising our strong in-house decommissioning capabilities and real-time monitoring technology, we saved valuable project time during the cutting process while ensuring the project was completed to the highest standards for our client.”
This represents the latest success for the company since the launch of the decommissioning business line.
