RockLock mechanical packer
Eliminate annular flow and ensure more uniform inform along the lateral of your well with the RockLock™ openhole packer from Baker Hughes. A key component in annular isolation, the packer also helps optimize production, delay water/gas coning, and provide positive isolation in your multistage frac applications.
The Rocklock openhole packer incorporates an innovative packing element and backup system that run as an integral part of the completion string. Available in both a standard and a 15k-psi version, the packer provides a reliable seal between the completion system and wellbore during your hydraulic fracturing and zonal isolation applications in extreme, high-pressure/high-temperature (HP/HT) well environments. Using the first additively manufactured backup system and the proprietary Aptum™ seal, the RockLock packer creates a long-lasting, reliable seal in irregular openhole wellbores—regardless of fluid type or temperature ranges. The packer’s metal backup system with a high-extrusion resistance elastomer performs reliably in large washouts in openhole sections. The packer is hydraulically set with lower differential pressure across the piston to help prevent damage to your formation. And with double the expansion percentage of the typical packer and four times the number of casing weights and sizes sealed with a single design, the RockLock packer leaves a fullbore inside diameter (ID) for unrestricted production. Confidently deploy the packer in the lower completion string between screens, slotted liners, frac point systems, and as means to isolate production intervals. You can also use the packer to isolate the open hole/liner annulus in an openhole completion in conjunction with stage cementing equipment.
