For shifting sleeves without profiles
The Well Key brings a high degree of flexibility and reliability to the well completion design as it can shift multiple sliding sleeves in a single run.
Running into the hole in a slick configuration, it is opened at depth and automatically engages with the hardware for which it was set-up for. Once engaged, the Well Stroker® provides the force to shift the hardware in the required direction.
Featured case
When wells are fractured using Coiled Tubing (CT) and frac sleeves are subsequently left closed, this typically means redeployment of CT for sleeve opening 48 hours later. While this process reduces the need for post-frac clean-out, there is a risk of the CT mechanical...
The Well Key Friction Grip increases operational efficiency in completions and interventions as it has been designed to allow the shifting and manipulation of multiple sleeves within a single run.
As the key operates by creating a high friction lock which can universally adapt to multiple profiles and does not require a specific single key profile, it can therefore be used to shift several different sleeves in one run. Its active hydraulic control and high expansion ratio ensure full integrity of downhole jewellery whilst the ability to have complete control from surface also reduces operational risk by ensuring the tool is only activated once on target depth.
