- Ensure permanent zonal isolation without having to pump cement to inflate a packer
- Protect cement during setting by blocking movement of gas or fluid
- Protect sensitive formations by isolating them from cement
- Run in single or stacked in multiples to provide increased seal length
- Isolate production intervals
- Isolate the open hole/liner annulus in openhole completions
Ensure a quality cement job and protect sensitive formations with the MPas™ mechanical packer from Baker Hughes. A primary cementing and zone isolation packer, the MPas packer uses a noninflatable packing element run as an integral part of the casing string to provide a robust, permanent seal between the casing and wellbore.
Assured sealing for the life of the packer
The MPas mechanical packer has an elastomeric element with composite structure, which is set mechanically by shifting a balance sleeve. This allows wellbore hydrostatic pressure to act against an atmospheric chamber and apply a setting force to the noninflatable element. The element is then mechanically locked, which eliminates the requirement of the wellbore fluid to maintain the set.
Wellbore hydrostatic pressure will continue to apply a setting force on the element throughout the life of the packer, which will compensate for any formation movement and will allow for additional setting force to be applied at any time. Additional setting force can be attained by applying additional pressure with a cup tool or by applying pressure to the entire casing string, if applicable.
The MPas packer is normally run in the liner string between screens, slotted casing, or gravel packed sections as a means to isolate production intervals. You can also use the packer to isolate the open hole/liner annulus in openhole completions in conjunction with stage cementing equipment. And for your deep wells requiring stage cementing, the MPas packer can protect lower zones from the high differential pressure of a long column of cement.
