Control zonal flow where it was previously prohibitive
TRFC-LT direct-position tubing-retrievable flow control valves expand the economic
feasibility of intelligent completions to lower-productivity wells. They can be part of
an integrated intelligent approach or installed as stand-alone tools.
The valves are actuated from surface by applying differential hydraulic pressure
across a balanced piston. The balanced piston design eliminates the need to
counteract control line hydrostatic head during operation.
This valve controls flow between the annulus and tubing; flow enters the valve
radially. Two versions of the valve are available: on-off or four position. For the
multiposition valve, various choke bean sizes are available. When the valve is fully
open, there is no restriction to fullbore flow.

Cost-effectively optimize well performance
TRFC-LT valves enable cost-effective optimization of well performance by reducing
unwanted water and gas production. Zonal control improves production or injection
sweep. Operators can enhance dynamic reservoir characterization through periodic
zonal tests without need for interventions. Using surface-controlled chokes also
eliminates the costs and risks of several other well interventions (e.g., to adjust the
chokes) that would otherwise be required. When used in conjunction with PT
gauges, the valves enable accurate production allocation.
Customizable choke is available in on-off or four-position
Direct-position valve can shift directly from any
position to any other position.

Each valve in the well has a dedicated “open” line,
while the single “close” line is shared by all.
Integrated bypass slot is provided for electrical, fiber-optic,
or hydraulic line(s).
What do these valves replace?
Downhole interventions to adjust zonal contribution via mechanically shifted sliding
How many control lines are required?
A single-zone well requires two hydraulic control lines. For multizone wells with
multiple TRFC-LT valves, each valve has a dedicated “open” line while a single
“close” line is shared by all (i.e., n + 1 lines for n zones).
