Gulf of Mexico: Petrobras: Cascade, Chinook reach 40,000 bopd mark
Brazil’s state-controlled oil company Petrobras has announced that on March 4, 2014, oil production from the Cascade and Chinook fields in the Gulf of Mexico, reached 40,000 of barrels of oil per day level.
This is a production record for the fields so far. Petrobras said that this output level was reached due to the fact that two new wells , Chinook-5 and Cascade-6, have entered into production, which added 28,000 barrels per day to the previous production level of 12,000 barrels per day.
The Cascade and Chinook fields are located in the Walker Ridge area of the Gulf of Mexico, approximately 300 km (180 miles) south of the Louisiana coast, at a distance of 24 km from each other. Water depth in the area is 2,590 m (8,500 ft).
Oil is produced through the BW Pioneer FPSO, the first floating production, storage and offloading unit approved to operate in the U.S. Gulf of Mexico.

S. America – Brazil
Petrobras Announces Farfan Discovery
Oct 11, 2012 – Petrobras announced the discovery of light hydrocarbons at its Farfan prospect in block SEAL-M-426 offshore Brazil. Well 1-BRSA-851-SES is being drilled in 8,923 of water by the Deepsea Metro II (UDW drillship). A hydrocarbon bearing zone of 144 feet was discovered at a depth of 18,314 feet and was confirmed by wireline testing and fluid sample analysis. The rig will continue drilling to the target depth of 19,685. Petrobras and partner IBV Brazil hold 60% and 40% interest in the well respectively.
Oct 11, 2012 – Petrobras released preliminary drilling results concerning appraisal well 3-RJS-683A at the Jupiter prospect confirming a discovery of natural gas and condensate. The discovery has proven a continuous reservoir between 3-RJS-683A and the Jupiter discovery well. A 577-foot oil column has also been detected in rocks displaying excellent permeability and porosity. Further appraisal is needed to determine the size of the field but initial estimates suggest that Jupiter could hold as much as 1 billion cubic feet of gas. To this point, the well has reached a depth of 17,834 feet and drilling will continue in an effort to reach deeper targets.

Lundin Announces Albert Results
Oct 11, 2012 – The Bredford Dolphin (mid-water semisub) wrapped up drilling operations at Lundin’s Albert prospect offshore Norway. Well 6201/11-3 was drilled to 9,760 feet and penetrated a thin Cretaceous oil bearing reservoir. The reservoir was found at a depth where the primary target was expected to be encountered. Due to the makeup of the structure and uncertain distribution, an estimation of resources in place cannot be made at this time. A minor column of movable hydrocarbons was encountered in a Paleocene secondary target. Further geophysical and geological studies are required to clarify the potential of the discovery.

Providence Encouraged by Barryroe Development Modeling
Oct 9, 2012 – Providence Resources recently completed a suite of static and dynamic modeling of the main Basal Wealden oil bearing reservoir interval within the Barryroe complex offshore Ireland. Data from the new models was incorporated with maps made from the recent 3D seismic survey of the area allowing Providence to establish oil recovery factors ranging from 17% to 43%. A modeled recovery factor of 31% over 25 years was achieved based on a development scenario which implemented 41 horizontal production and 22 horizontal water injection wells. Also, the company awarded the Barryroe Concept Development Engineering Study to Procyon Oil and Gas. Procyon will help determine the best development plan for the field based on the different scenarios recently modeled by Providence.

Lufeng FSOU Gets an Upgrade
Oct 9, 2012 – InterMoor completed its first permanent mooring project in the Lufeng field in the South China Sea. The company was contracted by CNOOC to handle project management, engineering, procurement and installation of a new buoy turret mooring system for the Nanhai Sheng Kai FSOU. Installation of the new mooring system should allow CNOOC to get an additional 15 years of service life out of the vessel which was first deployed in 1992. Included in the work scope was the addition of a new 8-inch flexible flowline and riser between the mooring system and LF13-2 wellhead platform. The FSOU was previously anchored in the LF13-1 field but has been moved to the 13-2 field since the upgrade to expand development there.

Brazil: InterMoor Completes Conductors for Papa Terra Project
InterMoor, an Acteon company, has completed installation of the drilling and production conductors for the Papa Terra project, announced Global President Tom Fulton. Petrobras serves as the operator of the Papa Terra concession with a 62.5 percent interest; Chevron holds the remaining 37.5 percent interest.
InterMoor was responsible for the design, procurement, fabrication and installation of 15 conductors for the project. Fabricated at InterMoor’s 24-acre, Morgan City, La., facility, the conductors are 36 inches (91 centimeters) in diameter and 187 feet (57 meters) long.
InterMoor chartered the Skandi Skolten, DOF Subsea’s Construction Anchor Handling Vessel, and the installation barge with a customized conductor launch system. For conductor driving, InterMoor used MENCK’s MHU-270T DWS which included a deepwater hydraulic hammer capable of providing a driving energy of 270 kilojoules at a water depth of 3,281 feet (1000 meters) combined with MENCK’s girdle-type electro-hydraulic power pack and umbilical support system. Generating hydraulic power at depth, rather than at the surface, means no hydraulic hose, therefore minimalizing environmental impact and energy loss.
The conductors were installed in water depths of 3,937 feet (1,200 meters) in the southern Campos Basin off the coast of Brazil. The installation took place in April 2012. InterMoor’s conductor services optimize conductor design to meet project-specific load and fatigue requirements, and the unique patented installation method allows installation without the need of a construction vessel. A standard Anchor Handling Vessel is sufficient, leading to a more economical installation off the rig’s critical path.
“We are proud to have successfully completed this important installation for Petrobras and to be part of the first offshore tension-leg, wellhead platform in Brazil,” said Fulton. “Our collaboration with sister company MENCK proved to be an effective partnership, and InterMoor remains the only company worldwide to offer a full conductor installation service in deep water.”
“InterMoor has been developing its strength in the Brazil market through our office in Rio de Janeiro, and this project completion confirms the breadth of our capabilities in the region,” added John Riggs, Managing Director for InterMoor do Brasil.
