OTC: Moho Nord Startup Marks Milestone for Congo
Innovations characterize the deepwater Moho Nord field development, recently brought on stream by Total in the Republic of Congo, and the project creates significant value for the country.
Shell: New Deepwater Project Can Break Even Below USD 40 Oil Price
The international major's low-cost development plan calls for a subsea tieback that will transport oil and gas through a single flowline to an existing floating production facility.
Real-Time Production Surveillance and Optimization in a Mature Subsea Asset
A real-time production-surveillance and -optimization system has been developed to integrate available surveillance data with the objective of driving routine production optimization.
How To Develop a Well-Specific Capping-Stack Blowout Contingency Plan
Developing a well-specific subsea-capping contingency plan involves assessing the feasibility of deploying a capping stack from a floating vessel, determining the weight and stability, and performing dynamic-flow simulations of closing the capping stack outlets.
Offshore Production and Flow Assurance
Subsea tieback of a new field to an existing offshore production facility is one option to minimize development costs.
Sapinhoá Field, Santos Basin Presalt: From Design to Execution and Results
This paper presents the development of Sapinhoá field, covering the fast-track transition and decision-making process, from appraisal to conceptual and basic engineering of the Sapinhoá pilot project and on to its subsequent execution, highlighting the challenges, lessons learned, and results.
Operators Begin Considering Pumps on Older Subsea Fields
The sharp downturn in the offshore oil business has sparked interest in using subsea pumps to add production. If those conversations turn into orders, it may convert this rarely used option into a commonly used tool for extending the life of offshore fields.
Standardization and Replication in Redevelopment-Project Subsea-Tree Design
Successful rejuvenation of two declining fields was enabled through innovation in both engineering and procurement strategy.
Thermal Effects on Subsea-Wellhead Fatigue During Workover Operations
Intervention and workover operations can significantly affect the structural integrity and fatigue life of subsea-wellhead systems. Methodologies for wellhead-fatigue analysis have improved, but have yet to account for thermal effects along the well. This study analyzes those thermal effects.
Rethinking the Blowout Preventer
A new blowout preventer design shows potential for delivering much greater shearing power than current BOPs. The design is simpler and more efficient than current BOPs.
Increasing Efficiency, Safer Operations Key Themes at OTC
As it has since 1969, the world came to OTC to make critical decisions, share ideas, and develop business partnerships to meet global energy demands.
Wireline Method Offers Faster, Cheaper Plugging for Deepwater Wells
A new method for accessing and cementing hard-to-reach spaces around complex offshore wells.
Norway Faces Up to Harsh Conditions
The need to economically invest in offshore exploration and production has inspired a wide range of innovations in Norway to drastically reduce costs, which can lead to changes in offshore operations around the world.
Subsea Price War Demands Cost-Saving Innovations
Anyone selling something new for offshore exploration and production has to be able to answer a simple question from customers, “How can we save some money?” For Norwegian oil companies, change is coming in many forms: steel, sensors, software, and standards.
Really Remotely Controlled Underwater Vehicles
Operators for remotely operated vehicles will be getting more remote in the future as land-based control begins to become a reality.
Subsea Production Optimization in Field BC-10 Offshore Brazil
The BC-10 asset, located in deep water offshore Brazil, produces heavy oil in the range of 16 to 24 °API. In this article, two examples of production optimization for this field will be provided (further examples are available in the complete paper).
CLOV Project: Overview
This paper describes the CLOV deepwater megaproject in Block 17 offshore Angola, which cost USD 8.4 billion to first oil.
DNV GL Launches Initiatives To Reduce Cost of Qualifying Composite Materials
To help lower costs of offshore projects, DNV GL has launched initiatives focused on the use of composite components.
New Improvements to Deepwater Subsea Measurement
A RPSEA project identified the gaps in technology that are the most pressing for multiphase-flow measurement.
Treating Damaged Subsea Lines With a Light Electrical Touch
As subsea electric lines age, they are prone to cracks that allow seawater in, reducing their effectiveness, and if the leaks are bad enough, they can shut down operations.
Offshore Europe: Statoil North Sea Discovery Moves Toward Production
Statoil is going to work to put its enormous Johan Sverdrup discovery into production, showing that even one of the most explored parts of the North Sea still has significant potential.
