Profile: Impact Selector, Inc. manufactures, rents, and leases a comprehensive line of technologically advanced mechanical impact tools for open-hole & cased-hole wireline operations. Our jars allow for more efficient and safer operations in the harshest environments by staggering costs associated with stripovers, fishing, & rig downtime. Our tools are designed to accommodate the threading, through-cable wiring, and crossover connections of Schlumberger, Baker Atlas, Halliburton, & other service companies' tool strings. Our Open-Hole MCT is a multi-conductor, all-mechanical open-hole jarring tool. Our Xcalibur™, cased-hole mechanical wireline jar offers in-the-string-adjustability plus the dual-purpose versatility of an e-line jar and a slickline jar in one. All our wireline jars employ patented or patent-pending technology which utilizes stored kinetic energy to maximize impact ratios.
