Schlumberger isolation barrier valves safeguard reservoirs by providing a reliable barrier between the wellbore and formation and by containing fluids during completions and workover operations—preventing damage to the formation and minimizing workover costs.
Isolation valves will help you increase wellbore safety by isolating the formation and containing reservoir fluids, increase efficiency by enabling batch drilling and completion operations, and enhance production by preventing formation damage.
Schlumberger installed the industry’s first barrier valve in 1996. Since that time, we have installed more than all other manufacturers combined―more than 1,700. Today, all our isolation valves use core technology components from the original FIV formation isolation valve, resulting in the most tested and reliable isolation barrier valves available.
We offer isolation valves to suit a range of
The FORTRESS valve isolates reservoir fluids in the lower completion and allows operators to transition from the lower to the upper completion without intervention. It is designed to withstand severe debris environments and optimize the available actuation energy— predictably, consistently, and reliably.
The FIV-II formation isolation valve allows transition from completion to production without exposing the formation to damaging kill fluids, thereby maximizing well productivity and optimizing hydrocarbon recovery.
This mechanical version of the FIV-II formation isolation valve serves as a bidirectional barrier to isolate the reservoir fluids within the lower completion, protecting the formation from damaging fluids.
The AFIV annulus-controlled shrouded isolation valve is used in selective multizone intelligent completions and uses a sleeve-type barrier, not a ball, to isolate the tubing from the annulus.
Actuated from surface through a single or dual control lines, this valve serves as a barrier to isolate reservoir fluids within the lower completion and maintains its pressure integrity through multiple operating cycles.
This interventionless tool allows automatic filling of the tubing, multiple completion pressure tests before and after setting the packer, annulus fluid circulation, and hydraulic setting of the packer before cycling open to allow fullbore through-tubing access.
Designed for pre- and postproduction or pre- and postinjection applications, these bidirectional barrier valves can be opened and closed multiple times, while maintaining pressure integrity over their predetermined life cycle.
Two options are available for triggering one-time remote opening for a number of our isolation valves—the nitrogen trigger and the s-trigger.
