Product Sheet Wellhead Isolation Tool
Protect production equipment from high pressures and abrasive fluids.
When a well is equipped with a production tree and wellhead that are rated below the minimum requirements for a stimulation treatment, the original tree, and sometimes the wellhead, is replaced with higher-pressure rated equipment, requiring the operator to kill the well and risk damage to the formation.
The wellhead isolation tool eliminates the need to replace the tree or the wellhead. It enables higher-pressure treatments to be performed on wells with lower-pressure production trees and wellheads by isolating the stimulation pressure and flowback.
The 15,000-psi [103.4-MPa] -rated system contains high pressures within the tool, protecting expensive valves and fittings from contact with abrasive, corrosive fluids. As a result, production equipment life is extended, and capex investment is reduced.
Deployment is streamlined and flexible. The portable, hydraulically operated tool can be installed with the well dead or under pressure without the aid of a workover rig.
Additionally, with the global presence of Schlumberger, the tool can be quickly rented, deployed, and used with less downtime at the rig site.
