Karoon Energy Ltd has reported that its contract with Maersk Drilling for the Baúna intervention campaign has commenced, following the receipt of all permits and regulatory approvals required.

After loading supplies and equipment for the programme, the rig departed Rio de Janeiro on 8 May BRT and arrived at the PRA-2 well site in license BM-S-40 (Baúna), southern Santos Basin. The rig moored, using pre-installed mooring buoys, and the first Baúna intervention in the four-well campaign commenced on 15 May BRT.

The intervention campaign, which is aiming to add 5,000-10,000 bopd to Baúna production, comprises the installation of new electric submersible pumps in the PRA-2 and SPS-92 wells, installation of gas-lift equipment in SPS-56 and re-opening of the lower zone of the BAN-1 well.

The campaign is anticipated to take four to five months to complete. The Maersk Developer rig is then scheduled to drill two development wells on the Patola Field and, subject to the receipt of required regulatory licences, one or potentially two control wells on the Neon oil discovery.

Karoon Energy’s CEO and Managing Director, Dr Julian Fowles, commented, “The commencement of the Baúna intervention programme represents the culmination of more than 18 months of detailed planning and hard work from the Karoon teams and our contractor partners in Australia and Brazil.

“Our key focus is on delivering this campaign safely, efficiently and on schedule, in close cooperation with the operator of the drilling rig, Maersk Drilling. We will update the market on progress in the June 2022 quarterly report.”

To help TotalEnergies – an oil and gas company – with a deepwater plug and abandonment (P&A) challenge offshore in the Brazilian pre-salt, Welltec, an international provider of robotic well solutions for the oil and gas industry, designed and manufactured a unique solution utilising a 414 Well Cutter equipped with a new Tiger Claw cutting element.

The well had been designed without a completion disconnect device, adding difficulty to the overall series and increasing the timeframe, if additional intervention and fishing was required.

To maintain optimal efficiency, a tool capable of cutting beyond the outer diameter of the 6 5/8 inches super 13Cr tubing and through the control line flatpack (with two Incoloy tubes) would be required. Furthermore, it was crucial that this be achieved in a single run.

P&A is a necessary operation at the end of a well’s productive years. Efficiency is vital during preparation and execution phases in order for operators to minimise costs, especially given the asset will be decommissioned and no longer producing.

Prior to the operation, multiple tests were carried out at the headquarters and subsequently at a local base in Brazil. These were done to ensure that a clean cut could be achieved all the way through to the flatpack in scenarios involving different cutting locations, in consideration of margins of error, as well as levels of slack or tension on the flatpack which would affect the cut.

Test cut locations included just below the clamp (15 cm), within the tubing connection (to see if the additional material could be cut), and in the middle of two clamps where it was anticipated the control line may be too slack.

Despite successful test cuts just below the clamp, and within the tubing connection, the client opted for a middle of the tubing cut. A 414 Well Cutter was run in hole with specially designed Tiger Claw cutting element and activated six meters below the clamp.

As an additional precaution, a physical limitation was implemented to restrict the cutting range of the Tiger Claw to 8.2 inches, therefore de-risking the operation in terms of the 8.5 inches outer casing being compromised. The angled cutting arms were able to cut through the tubing and control line flatpack as predicted.

After pulling out of hole, the operator was able to pull the completion, seeing the control line flatpack shear six meters below the clamp. As a result of this operation, TotalEnergies was able to save time with tubing retrieval, avoiding the delays that would have followed a cut to only the tubing.

The newly designed Tiger Claw cutting element provided an increased cutting range in comparison to its predecessors, guaranteeing a continuation of cutting beyond the outer diameter of the tubing, and through the control line flatpack.

Baker Hughes has expanded its presence in Guyana by opening a new local supercentre facility for oilfield services and equipment.

Spanning more than eight acres, the supercentre will support regional customers and bolster Baker Hughes’ localisation efforts within South America.

In the country, the company currently provides drilling services, drill bits, and drilling and completion fluids to several drilling rigs, with its completions and wellbore intervention product line supporting all upper completions for development wells in Guyana.

Baker Hughes’ Turbomachinery & Process Solutions (TPS) and Upstream Chemicals businesses also provide technology and solutions to the second floating production, storage and offloading (FPSO) vessel in Guyana, known as Liza Unity as well as other projects in the region.

The supercentre has been built together with Baker Hughes’ existing completion warehouse and liquid mud and completion fluids plant, providing full support to customers in Guyana and Suriname. It represents a multimillion-dollar investment from Baker Hughes over 15 years and includes a workshop, warehouse, and laydown storage yard including maintenance facilities and equipment.

The facility is expected to employ more than 100 employees within five years, and the majority are expected to be Guyanese.

“This announcement significantly expands Baker Hughes’ ability to support Guyana’s energy goals and its leading oil and gas projects,” said Maria Claudia Borras, Executive Vice President for Oilfield Services at Baker Hughes, during the facility’s opening ceremony.

“Baker Hughes is well-known in the region for service and technical excellence, and our new Guyana supercentre will bolster our efforts to expand even further into the evolving market. We are proud to be here, and we look forward to this exciting next phase in our work.”

Brazilian state-run oil company Petrobras has opened a public consultation to obtain information from suppliers on alternative technology for retrieving flexible pipelines in the Marlim field, off Brazil’s southeast coast.

According to the state-run oil firm, the service to be hired is particularly challenging because some of the pipes that lie 1,250m under water do not have the necessary structural strength to guarantee their retrieval.

That is, under the premise that the pipelines would not support their own weight under a catenary (curves forming a U shape) equivalent to or close to the water depth in which they are installed, they must be retrieved using a resource or tool that is submerged to the proper water depth.

The tool must avoid dredging the seabed and not come in contact with any equipment that may be installed there, remaining at a minimum distance of 30m from the seabed.

The recovery must be done by a reel system within the standard used by Petrobras in its operational bases. In addition, there is a need to use smaller vessels, such as ROVs (remotely operated support vessels), for example, as there are currently a reduced number of operational bases that support vessels of the size of PLSVs (pipelay support vessels).

A possible solution proposed by Petrobras comprises a recovery method consisting of descending a reel drive system to a fixed distance from the seabed, close to 50m (enough to avoid colliding with obstacles and subsea systems), therefore minimising the catenary generated during the recovery.

The completion and submission of the public consultation, with the title ‘Subsea Reel Drive’, must be done by 4 March, 2022.

Located in the Campos basin, the Marlim field is going through a revitalisation process, which encompasses the installation of two new FPSOs (Anita Garibaldi and Anna Nery) and the decommissioning of several production units (P-18, P-19, P-20, P-26, P-27, P-32, P-33, P-35, P-37 and P-47) and associated subsea equipment.
