AI Technical Summary

Technical Problem

Traditional well packers with single support members suffer from energy loss during pressure reversals, leading to inadequate sealing performance.

Method used

Implementing a well packer design with two supports, a fixed and a movable support, that compresses the sealing element from both ends to enhance sealing efficiency.

Benefits of technology

The double-support design provides improved sealing pressure and maintains a water-tight seal under pressure reversals, reducing energy loss and enhancing sealing effectiveness.
