There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade. The market for subsea vessel operations in field development; inspection, repair, and maintenance (IRM); and subsea well intervention is expected to grow 63% during 2012 to 2016.
Low prices will constrain maintenance and modifications in the coming year. However, maintenance can only be delayed so long, leading to a long-term outlook of growth in the market for maintenance, modifications, and operations. There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade. Compared to the US industrial average downtime ranging from 3% to 5%, the oil and gas industry’s estimated downtime ranges from 5% to 10%,indicating that improvement is needed in reliability and maintenance of facilities, equipment, and processes.
The outlook in the UK is a case study of the squeeze facing E&P in other basins where operators are trying to pay to sustain production with discoveries, while plugging and abandoning old wells, all paid for by the lean cash flow due to low oil prices. Subsea inspection/repair/maintenance services have traditionally relied on vessel-based, ROV, or diver operations. In the longer term, identifying significant incremental savings in these operations is not sustainable and an innovative approach deploying digital technologies is being investigated. The deal gives Equinor an additional 7.5% ownership stake in the Njord redevelopment project and associated tiebacks in the Norwegian Sea, and potentially raises Faroe’s value in the midst of a hostile takeover attempt by DNO. Startup comes 8 months after the initial discovery in March, marking the second successful tieback since 2017 to the Beryl Alpha platform in the UK North Sea.
The complete paper proposes an azimuthal plane-wave-destruction (AzPWD) seismic-diffraction-imaging work flow to efficiently emphasize small-scale features associated with subsurface discontinuities such as faults, channel edges, and fracture swarms. This paper contrasts the detailed perforating and flowback plan with the results of the operation where a number of planned, and some unplanned, contingencies were faced. A hybrid downhole microseismic and microdeformation array was deployed to monitor fracture stimulation of a vertical coal-seam-gas (CSG) exploration well in the Gloucester Basin in New South Wales, Australia, to provide more-accurate insight into overall fracture height. This paper outlines the key issues that must be addressed from a regulatory perspective in regard to the development of an onshore unconventional-gas industry in the Northern Territory. This paper provides an insight into the challenges encountered and overcome during installation of 20 subsea structures, some close to 1000 t in weight and in water depths of up to 1350 m, for the Gorgon project offshore Western Australia.

In the longer term, identifying significant incremental savings in these operations is not sustainable and an innovative approach deploying digital technologies is being investigated. GATE will provide facility commissioning and Subsea 7 will provide a pair of infield production flowlines and the umbilical system for Shell’s recently sanctioned deepwater GOM development. Executives from several service companies involved in the offshore space—including two sides of a recent hostile takeover bid—came together at OTC to discuss the virtues of collaboration and rationale behind M&A. McDermott’s board of directors rejected an acquisition offer from Subsea 7, which called for McDermott to abandon its planned $6-billion combination with CB&I.
If sanctioned and developed, the deepwater Pecan field would be Ghana’s fourth producing offshore field. First oil is expected 35 months after sanction, which could come as early as this year. The steel pipe manufacturer agrees to deliver outer pipes for pipe-in-pipe flowlines for a pair of recently-announced Aker BP projects in the Norwegian Sea. Oilfield Services: How Much Consolidation is Yet To Come? The recent upswing in M&As in the oilfield services sector may be a harbinger of more to come as operators push for capex and opex control.
BP and partners have sanctioned the Azeri Central East project, the next stage of development of the giant Azeri-Chirag-Deepwater Gunashli oilfield complex in the Azerbaijan sector of the Caspian Sea. The startup of a second FPSO will add 115,000 BOPD to the deepwater project offshore Angola, bringing overall production capacity to 230,000 BOPD. If sanctioned and developed, the deepwater Pecan field would be Ghana’s fourth producing offshore field. First oil is expected 35 months after sanction, which could come as early as this year. Are Deepwater Projects Due for a Revival?
High-fidelity 3D engineering simulations are valuable in making decisions, but they can be cost-prohibitive and require significant amounts of time to execute. The integration of deep-learning neural networks with computational fluid dynamics may help accelerate the simulation process. The pipeline system will have the initial capacity to deliver 150,000 B/D of crude oil to multiple delivery points, accessing local refineries and connecting to several downstream pipelines. The independent oil and gas company is aiming to build shareholder value through a change in business focus to midstream with this step into pipeline service and construction. Phase 1 of the development today marked the sail-away from Kværner’s yard of the 560-bed living-quarters topside, the largest of its kind in Norway.
The move comes weeks after Gazprom announced a final development concept for the project. Other projects Shell is developing with Gazprom, including the Sakhalin 2 export facility, will not be impacted by the decision. The next big wave of decommissioning and abandonment projects is set to occur in the Asia-Pacific region, and APAC’s operators are now tasked with finding cost- and time-effective ways of unwinding their huge agglomeration of wells and facilities. This digital deal is helping to make augmented reality a new reality for oil and gas operations. The project framework agreement moves the proposed conversion of Lake Charles LNG’s import and regasification terminal closer to sanction, which is expected sometime this year.
Ashtead Technology has acquired Louisiana-based subsea equipment rental and cutting services specialist, Aqua-Tech Solutions, as part of the company’s international growth plans in the US. Aker Solutions and FSubsea have agreed to a joint venture, named FASTSubsea, to help operators increase oil recovery. Called Eelume, the underwater drone will perform subsea inspection, maintenance, and repair work. From its record high in 2014, purchases of subsea equipment and SURF fell around 50% until reaching a low in 2018. New data suggest that the subsea market will be a top-performing oilfield service segment.
