Isolate worthless lower zones or abandon the well, using Xpandable steel packer.
Challenge
To achieve the isolation of unwanted toe or lateral, you must overcome tough running in hole challenges, coping with troublesome initial bores, tight spots, or cut windows.
Solution
Open-hole packers can be used as plugs in P&A configuration, in combination of cement, or even cementless.
Saltel Xpandable steel packers precisely address tough RIH challenges considered their sturdiness with stainless steel expandable sleeves. Used as open hole barriers, Saltel packers can be run in difficult conditions, with cycles of overpull, rotation and circulation.
