Ball Type Fluid Loss Control Valve

The FLCV(Ball Type Fluid Loss Control Valve) provides a reliable, mechanical solution for fluid loss control during well completion, thus eliminating potential formation damage.
During sand control applications, the valve is run into the well (ball open) below the uppermost gravel pack packer as an integral part of the gravel pack assembly. The washpipe, located on the bottom of the gravel pack service tool, is extended through the valve. A collet shifting tool is attached to the end of the washpipe. Upon washpipe retrieval, the collet shifting tool closes the ball and isolates the formation, which enables inflow or positive pressure testing. The lower sandface completion and reservoir is isolated by the closed ball in the valve, which permits safe installation of the upper production completion.
This valve is opened mechanically using a collet shifting tool attached to the end of the upper completion. The closure device is a proven, high performance ball mechanism that provides a positive bi-directional seal in brine and oil-based mud environments. The debris-tolerant, non-translating ball design eliminates unnecessary movement within the mechanism during opening and closing operations.

Features:

● Initial valve closure is achieved when the washpipe/collet is retrieved through the valve.
● Bi-directional sealing mechanism provides a fully tested downhole barrier.
● Improved fluid management helps ensure valve operation in debris.
● Design provides unlimited mechanical valve opening/closing.
● Full bore ID maximizes production and allows access to the formation.
