With an emphasis on case studies, this bite-size event consistently provides members and their guests with a look at the latest and greatest that the industry has achieved.
Join us for our technical luncheon Tuesday, February 13th at the Norris Conference Center in Houston. We will kick off the meeting with lunch starting at 11:30 followed by our presentation at noon.
Wells on a production decline curve require intervention. Cleaning these wells out with conventional fluid regimes is ineffective and costly. Fluid loss due to hydrostatic pressure exceeding bottom hole pressure results in reduced annular velocities and excess fluid on the reservoir. Slick water fluid regimes offer poor hole cleaning which significantly increases the risk of stuck pipe and greatly reduces the operator's ability to properly intervene the well. Utilizing a variable density fluid with equivalent viscosity permits operators to successfully clean the wellbore lateral to TD and minimize formation damage.
The use of colloidal gas aphron (CGA) fluids results in effective well intervention and clean outs. Because the well can be circulated at balance, little to no excess fluid is placed on the reservoir. Variable density also allows operators to consistently reach TD and clean out the entire lateral, from the heel to the toe. The highly viscous properties of the CGA fluid entraps and carries debris from the well removing sand-bridges and other obstructions which impair production. Production is renewed and the well can again be put online. Applications of CGA fluids include intervention on low bottom hole pressure wells where the lateral is to be washed or cleaned out. Frac-plug drill out operations with variable well pressure and preparing the well for refracturing or restimulation are also common applications.
