Roxar ASA announces that part of its NOK 45 million subsea contract announced to the Oslo Stock Exchange in early April will be the provision of integrated reservoir sensors and multiphase measurement systems to Petrobras America, a subsidiary of Petrobras for operation in the Gulf of Mexico’s Cascade and Chinook fields. The deal is worth NOK 19.5 million.
Petrobras America will install the Roxar subsea Multiphase meter, which provides accurate and continuous on-line monitoring of the flow rates of oil, water and gas in subsea well streams. Roxar will also install a number of SenCorr SEPT combined sand erosion and pressure & temperature sensor systems to provide valuable real-time information on the subsea reservoir. The sensor is truly redundant with separate sensing elements, wiring and electronics, and can operate with high accuracy at up to 15,000 psi (pound per square inch).
The Cascade and Chinook fields are located in the Walker Ridge Outer Continental Shelf (OCS) leasing area of the central Gulf of Mexico. Cascade is located about 260 kilometers south of the Louisiana coast in 2,500 meters water depth and Chinook is about 25 kilometers south of Cascade in 2,650 meters water depth. Wells will be drilled to a total depth of approximately 8,230 meters.
Due to reservoir uncertainties, a phased development is underway with Phase 1 (two subsea wells in Cascade and one subsea well in Chinook) analyzing reservoir performance to ensure increased production and flow assurance in future stages.
At such depths with high pressure and flow rates, Roxar’s solutions will provide Petrobras with critical, real-time information on the wells’ capabilities during production. Information will include water saturation and possible breakthrough, gas coning, permeability and flow characteristics, sand erosion, and pressure and temperature information.
Roxar CEO, Gunnar Hviding said:
“Today’s announcement with Petrobras is great news for Roxar’s operations in America as we continue to consolidate our position in the Gulf of Mexico. In addition to the major role we are playing in guaranteeing flow assurance on the Independence Hub, our work in the Cascade and Chinook fields will further consolidate our credentials as the leading provider of robust and accurate measurement and monitoring solutions in some of the world’s deepest offshore fields.”
“We look forward to helping Petrobras move to Phase 2, reducing uncertainties in the reservoir, and maximizing reservoir production and increase production regularity.”
