The China based joint venture between international oilfield services companies, Expro, and China Oilfield Services (COSL) has been awarded a subsea well testing contract worth in excess of US$25million by Husky Oil China Ltd.
These services will be deployed by Expro and COSL’s joint venture, CETS, which is based in Shekou, Shenzhen South China. This service supports the second stage of Husky’s Liwan gas field subsea development in the South China Sea. The three-year contract includes a surface clean-up and flow-back package with the ability to flow and measure high gas rates.
Expro’s subsea safety systems provide reliable and efficient in-riser landing strings for well interventions and completions. Expro is already well established in the deepwater regions of the world, including Africa, Gulf of Mexico and Brazil.
CETS has installed surface equipment to handle the expected high flow rates while supplying Husky with accurate detailed data for further field appraisal. This work in the deeper waters of the South China Sea presents a number of challenges including readiness to unlatch at short notice during the typhoon season.
Expro’s modular process equipment measures the performance of a well with acute accuracy. Testing involves flowing the well through a temporary completion and production system in order to measure flow parameters, and to gather representative fluid samples for analysis. These measurements are used to determine commercial viability, as well as to plan potential future completion and production facilities.
Expro’s Express and ELSA in-riser electro hydraulic landing string system will allow the safe installation of all of Husky’s subsea completion operations from the assigned DP drilling rig guaranteeing fast and secure well isolation and system disconnect during the critical well clean-up operations and completion deployment.
Peter Quiatkowski, JV general manager, said: “An award of this size demonstrates the combined strength that Expro and COSL bring to the market. The joint venture is well equipped to meet the challenge and this contract is evidence of our capacity to deliver specialist services and provide the most accurate and reliable results.”
Graham Cheyne, Expro’s subsea sales director, said: “This is the first deployment of Expro’s large bore electro-hydraulic landing string systems in Asia and the first deepwater subsea development in China. This clearly shows our position as deepwater players in China and will further develop Expro’s commitment to working with Chinese nationals and enhance our relationship with our joint venture company.”
