Casinjac is an industry leader in national casing jack field service operations, casing jack manufacture, and jack refurbishment headquartered in Elk City, Oklahoma. In 2012 Casinjac became a part of the SFI Oil and Gas Production Systems, a Tri-Point Company. Since purchasing Casinjac, we have made safety and accountability our highest priority. Our casing jacks are the safest alternative when pulling stuck production slips, trying to free impacted casing, and supporting pipe string weights greater than a rigs safety limits allow. We have full traceability throughout the manufacturing process and have had our service units independently tested to assure we have the safest equipment available to operating and well service companies.
