InterMoor, an Acteon company, has successfully completed a contract with Cross Group, Inc. that included the provision of heave-compensation services for the installation of a Cross 7.0 workover riser package (WRP).
An InterMoor compensated anchor-handler subsea installation method (CASIM) unit played a key role in deploying and recovering the WRP.
“The CASIM system enabled us to provide effective heave compensation and to recover the delicate WRP on a vessel without an active heave-compensated crane or stern roller,” said InterMoor vice president of business development David Cobb. “That was the only way to achieve the WRP installation from this vessel. The success of this project underlines the value of the CASIM system as a cost- and time-effective solution, and explains why more and more subsea contractors and operators are choosing it to facilitate the installation of workover packages.”
Each standard CASIM unit has a maximum stroke of 3 meters and can accommodate loads up to 50 tons.
The heave compensation operation was in water depths of about 140 meters and used Cal Dive’s Uncle John DP saturation diving vessel to install the 29-ton WRP. The project took place at East Cameron well 378#3, offshore Louisiana, USA. The Cross Group is conducting a plugging and abandonment (P&A) program in the field for EPL Oil & Gas, Inc.
This project demonstrates how InterMoor can provide cost-effective solutions for the installation of subsea workover equipment using vessels of opportunity. Operators trust InterMoor to be part of their P&A campaigns and to help them meet BOEMRE NTL No. 2010-G05 requirements for timely decommissioning of idle infrastructure on active leases.
Claxton, an Acteon company, which specializes in engineering and services for jack up environments, has presented its SABRE subsea abrasive cutting system.
The Claxton SABRE abrasive cutting system is capable of simultaneously severing all the casings in a well, regardless of casing loading, eccentricity or contents.
SABRE has proven an invaluable tool and has seen successful use on some of the most significant abandonment campaigns. SABRE’s abrasive jet exits the tool at transonic speeds – making light work of even composite materials such as cemented casings.
Using a jet of naturally occurring cutting components (garnet, water and air), SABRE has a low environmental impact. The system can be deployed from a vessel or platform, allowing simultaneous abrasive cutting of multiple well casings without impacting adjacent infrastructure.
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.

Nov 7, 2012 – TD has been reached in the Ioana-1 well in the Romanian sector of the Black Sea. Gas shows were encountered in the Sterling Resources-operated well from 1,640 feet to the total depth of 6,397 feet. The main objective identified by 2D seismic was encountered as prognosed but was found to be made up of thinly bedded sands within low permeability siltstones. Shallower gas bearing sands were intersected but formation details won’t be known until cased-hole logs are thoroughly reviewed. Sterling indicated that it might seek to acquire 3D seismic data over the area to gain a better understanding of the complex formations encountered while drilling Ioana.

Europa Eyes Irish Atlantic Margin Prospects
Nov 9, 2012 – Europa Oil and Gas has identified two previously unknown prospects, Mullen and Kiernan, in the South Porcupine Basin in the Irish Atlantic Margin. Both prospects are located in the company’s 100% owned Licensing Options 11/7 and 11/8. First pass seismic data has been reprocessed over Mullen while reprocessing is on-going over Kiernan. Resource estimates at Mullen range from 66 mmbo (P90) to 1092 mmbo (P10). Both prospects are characterized by Early Cretaceous turbidite reservoirs which, although proven in the North Porcupine Basin, are untested in the south. Results from the upcoming ExxonMobile Dunquin well may help to de-risk the area. Europa is currently looking for a joint venture partner to assist with maturing the prospects to drillable status.

Nov 7, 2012 – Diamond Offshore’s Ocean Vanguard (mid-water semisub) drilled another successful well in the Johan Sverdrup discovery area. Well 16/2-14 was drilled almost 4 miles northwest of Johan Sverdrup discovery well 16/2-6. The main objective was to collect data from the stratigraphic sequence above the reservoir to serve as the basis for field development decisions. A 98-foot oil column was encountered in Upper Jurassic reservoir rocks that exhibited good reservoir quality. The Hegre and Shetland Groups were encountered but reservoir quality was poor in both. The well was drilled to a total depth of 6,430 feet and will be permanently plugged and abandoned.
