Fluid Loss Control Devices

Eliminate the use of potentially damaging fluid loss control materials

Our fluid loss prevention devices help protect the reservoir in sand control completions. Placing a valve in the production string to isolate reservoir fluids eliminates the need for spotting potentially damaging fluid loss control materials after pulling the service tool from the packer assembly.

Fluid Loss Control Device Applications
Device Openhole Sand Control Cased Hole Sand Control Product Sheet
FORTRESS
premium isolation valve is a bidirectional barrier valve typically run with the lower or intermediate completion; it has been developed for deepwater and other harsh environments where debris tends to accumulate and hinder operation of conventional valves.

FIV-II
formation isolation valve serves as a bidirectional barrier to isolate reservoir fluids within the lower completion, enabling operators to transition seamlessly—without intervention—from the lower to the upper completion.

AFIV
annulus-controlled isolation valve is a shrouded version of the FIV-II formation isolation valve; it is used in selective multizone intelligent completions to separate production from the upper and lower zones.

Hydraulic dual-flow annular valve (HDFAV)
is a concentric annular fluid loss control device for the upper zone in intelligent and dual completions. It is incorporated in the lower completion string and eliminates the extra run required for an isolation string with an AFIV valve. It is hydraulically activated, with a mechanical shifting mechanism for backup.

Dual-flow annular valve (DFAV)
is a concentric annular fluid loss control device for the upper zone in intelligent and dual completions. It is incorporated in the lower completion string and eliminates the extra run required for an isolation string with an AFIV valve. It is mechanically activated.
