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.

The ultra-deepwater drillship, Titanium Explorer, started its drilling contract with Brazil’s Petrobras in the U.S. Gulf of Mexico, on Friday, December 7.
The Titanium Explorer, formerly known as the Dragonquest, owned by Vantage Drilling, is contracted for eight years.
Under the contract, Brazilian-state controlled oil company Petrobras has the right to re-locate and utilize the Titanium Explorer on a worldwide basis. Expected revenues over the eight-year contract term, excluding revenues for mobilization of the rig and costs escalations, are approximately $1.6 billion.
The drillship is a self-propelled, dynamically positioned vessel suited for drilling in remote locations because of its mobility and large load carrying capacity. It is currently equipped for drilling in water depths up to 10,000 feet, and is designed to drill in water depths up to 12,000 feet.
The Laguna Star, QGOG Constellation’s new ultra-deepwater drillship, arrived, Nov. 7, in Brazil. Samsung Heavy Industries shipyard, located in South Korea, built the Laguna Star as well as the Amaralina Star drillship, which is currently in operation by QGOG.
The unit will be operated by its subsidiary, Queiroz Galvão Óleo e Gás (QGOG), in water depths of up to 10,000 feet and well depths of up to 40,000 feet. It is equipped to operate in ultra-deepwater including the Brazilian pre-salt area.
The Laguna Star is the second drillship to be operated by QGOG, after Amaralina Star, which arrived in Brazil in August, 2012. The unit contributes to expanding and diversifying QGOG’s portfolio in ultra-deepwater drilling.
“The arrival of Laguna Star is another key milestone for the QGOG Constellation’s ultra-deepwater operations and, together with Amaralina Star, reinforces our operational track record,” said QGOG Constellation CEO Leduvy Gouvea.
These two drillships are chartered to Petrobras under six-year contracts, with options to renew for six additional years. Drilling services will be provided by QGOG.

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.

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.

Oct 11, 2012 – Heerema Fabrication recently completed construction of the new 750 ton process module for BP’s Andrew platform in the UK North Sea. The module was designed to be a “bolt-on” addition to the platform facilitated by the use of two large hinge pins that engage hooks welded to the existing structure. Heerema’s Hartlepool yard benefited from the project by the creation of 180 jobs. In addition, the module was delivered without a single lost time incident.

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.

Oct 9, 2012 – Ithaca Energy has acquired interest in the Cook and MacCulloch fields in the UK North Sea through the acquisition of two Noble Energy subsidiaries. The Shell-operated Cook field is located in block 21/20a and is processed through the Anasuria FPSO. The acquisition will bring Ithaca’s stake in the field to 41.345%. The ConocoPhillips-operated MacCulloch field is found in block 15/24b and was developed through 4 subsea wells tied back to the North Sea Producer FPSO. Finalization of the acquisition, expected in early 2013, will give Ithaca a 14% stake in the field. With the addition of these assets, Ithaca’s net production – largely oil – should increase by 1,100 boepd. The company’s total consideration in the arrangement is $38.5 million.

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.
Scarborough Partners Still Mulling Development Options
Oct 11, 2012 – ExxonMobil said a decision on how to develop the Scarborough gas field is not likely until the second half of 2013. Scarborough is considered one of the most difficult fields off Western Australia to develop. Water depth in the area is around 4,700 feet and the closest land is 170 miles away. The company is evaluating several options with its joint partner BHP Billiton. Some of the options include building a floating LNG platform or supplying gas to companies that have existing LNG plants.
Oct 9, 2012 – MEO Australia announced its intention to launch the farmout of exploration permit WA-454-P on Nov. 1. The farmout is scheduled to conclude by the end of 1Q 2013. WA-454-P, located in the Joseph Bonaparte Gulf, contains the Marina-1 discovery and the sizable Breakwater prospect. MEO describes Marina-1 as a “gas and probably oil” discovery with 3C contingent gas resources of up to 3.2 Bcf and 3C contingent oil/condensate resources of up to 29.5 MMstb. Gas-only perspective resources for Breakwater are up to 2.7 Tcf with 87 MMstb condensate. In addition, Breakwater is situated in an area near proven gas discoveries that are planned to be developed with floating LNG technology. MEO was awarded WA-454-P in June 2011 and holds 100% interest in the permit.
