Welltec | Advanced Well Architecture (AWA)

AWA - open hole intelligent completion solution

The AWA system provides zonal isolation and zonal control – the basis for an open hole intelligent completion solution. This new completion concept drastically reduces risk and variability in operations by delivering flexibility to the number of zones, thus absorbing reservoir uncertainties, and optimizing well construction via standardized structural design.

Applications

Controlled reservoir isolation
Access for deployment of intelligent well completions
ESP producers
Depleted reservoir losses
Deep water

Zonal isolation and control

AWA is comprised of our industry proven Welltec^® Annular Barrier (WAB)^® for zonal isolation and Welltec Flow Valve (WFV™) with Dual Position (DP) for inflow control. Ran in combination across an open hole reservoir section, this system facilitates full bore, cementless, zonal isolation and control.

The addition of Welltec's Downhole Actuator (DHA) onto the upper Intelligent Completion (IC) extended inner string engages with and mechanically shifts open the WFV-DP just prior to landing off the upper completion, providing flow access to the previously isolated zones. Welltec AWA enables safe deployment of intelligent completions in wells with losses.

Inflow from the reservoir via the WFV DP can then be controlled by hydraulically actuated interval control valves (ICV) incorporated within the upper completion. During any potential workover, the DHA will re-engage and shift multiple WFVs to a closed position. This in turn isolates the reservoir to the wellbore to enable re-completion and safe retrieval/replacement of inner completion without formation damage (no lost-circulation material pumping, etc).
