The major types of enhanced oil recovery include chemical and Co2 injections. The key concern regarding these operations is corrosion, so normally stainless steel is employed: normally but not exclusively. At the recent SPE/ICoTA Coiled Tubing and Well Intervention Exhibition in Woodlands, Texas, Inplex presented a polymer-based down hole tubing for chemical and Co2 injection called the “Injectorplex”. Injectorplex, designed for chemical and CO2 injections, eliminates the high cost of stainless steel tubing. Tested for more than seven years, Injectorplex has proved to be remarkably successful even under the most extreme conditions. Glenda Hanson of Inplex comments, “We started making this product 10 years ago. We worked together with Kerr-McGee and Marathon oil Corporation developing the material that would perform best in harsh H2S environments. We tried different types of combinations to find the right compound for the job. Now we had the experience in the field, but before we were taking it to the market, we had to make absolutely sure it was working.”
