Precision stimulation delivers results

摘要

A well planned and executed well stimulation is one of the primary methods to enhance production from both oil and gas reservoirs and increase injectivity to injection and disposal wells. Some key components for optimal stimulation treatments are the chemicals or treatment fluids themselves, the length and location of interval(s) that require stimulation and also the deployment or diversion method to be used. With the economics of some treatment fluids in the industry today more of an emphasis is being put on accurate placement of these fluids. This is highlighted more in marginal fields that may have a low reservoir pressure. When stimulating these wells with coiled tubing (CT) as the deployment method, control of the treatment fluid is paramount. In a high percentage of these low reservoir pressure wells a high overbalance in favor of the CT may exist, leading to fluid fall out of the coil at an uncontrolled rate.
