LONDON -- BP has awarded Expro a multi-year contract for the provision of equipment and services on block 31 offshore Angola.
The contract covers the delivery of landing strings for use on PSVM (Plutao, Saturno, Venus Matre). This is the first of up to four planned developments on block 31.
Expro Landing String Assembly (ELSA) technology allows the control of isolating valves which eliminates the requirement to set and retrieve wireline plugs providing well commissioning efficiencies, according to Expro. The landing string design will be standard across the program of work and will meet all the downhole functional requirements on the block 31 completions, the company says.
The ELSA valves will be controlled by Expro's Express Electro-Hydraulic control system. The control system has been specifically designed for well intervention systems and meets BP's dual redundant and control monitoring requirements.
The system allows dualbore completions to be deployed using a monobore landing string, allowing the wells to be flow-tested to the rig prior to installing the production trees. The system was designed in Expro's Aberdeen Engineering Technology Centre and the project will be delivered through the remainder of the year.
First offshore operations are expected to begin early in spring 2010.
