Offshore Installation Services (OIS), an Acteon company, has successfully completed its 16th rigless suspended-well abandonment campaign involving multiple operators in the Southern North Sea. The multi-operator model for programmes of this kind can deliver significant customer benefits in terms of cost-effectiveness. A total of nine mudline wells in categories 1, 2.1, 2.2 and 2.3 were abandoned during the operation including four on behalf of GDF SUEZ E&P UK Ltd. and two for RWE Dea.
The scope of work for OIS, part of Acteon’s activity and resource management business, included the initial approval processes; formulating the contracting strategy; developing detailed procedures; procurement; appointing specialist service providers; overall logistics; and recycling and disposing of the recovered wellheads.
OIS conducted the two-phase abandonment operation from a chartered DP2-class anchor-handling tug supply vessel (AHTS). During phase one, a proprietary twin low-pressure packer tool from Acteon sister company Claxton Engineering Services Ltd. was deployed through the vessel’s moon pool to set cement plugs across all the casing annuli. The second phase involved abrasive severance of the wells using Claxton Engineering’s SABRE cutting tool.
“We have a strong track record in providing commercially efficient decommissioning solutions which are particularly important for non-revenue-generating assets,” said OIS vice president of commercial and business development Tom Selwood. “Multi-operator campaigns such as this, enable operators to share the associated costs which, when combined with the rigless nature of our offering, makes this the most cost-effective way to comply with UK oil and gas decommissioning legislation.”
Max Proctor, GDF SUEZ E&P UK drilling manager, added, “We are committed to fulfilling our responsibility to the environment as an operator and are leading the way in the North Sea with the decommissioning of redundant wells. We started this campaign immediately after the request came from DECC for operators to fully abandon suspended wells by reviewing the history of the wells and confirming the status of each with an independent well examiner. OIS is a valued partner of GDF SUEZ and the success of this project is testament to the team’s strong technical skills and experience.”
Since 1996, the OIS team has successfully completed more than 100 well decommissioning projects without a single lost-time incident.
Aberdeen-based oilfield services firm Coretrax Technology Limited has secured over £1.2million of contracts since the start of the year and expanded its team to 12 people.
Coretrax specialises in innovative oilfield services to the completion, cementing, abandonment and wellbore clean up sectors both in the North Sea and globally. The contract wins are for projects in the North Sea utilising Coretrax’s innovative wellbore clean up tools and chemicals.
The team in Aberdeen has also expanded with the appointment of a new business development manager and offshore supervisor both bringing many years of oil industry experience to the company. Coretrax plans to recruit a further 6-8 new staff in 2012 including a second graduate in design engineering.
Kenny Murray, director and founder of Coretrax, said: “We have had a really promising start to the year and I’m delighted with the new members who have joined the Coretrax team. Our focus this year is continual R&D to expand our range of products and services to provide solutions to operators with our team of engineers globally.
“Our innovative approach to wellbore clean up has also led to successful projects globally and we are completing successful contracts in Africa, Middle East and Asia. We will continue to expand both internationally and in the North Sea with on-going recruitment and new premises this year.”
