Bench modeling of the well killing process

Well killing is a complex process that requires accurate technical and mathematical approaches. The well killing process impacts well production performance. This article examines well-killing operations to enhance our understanding of the processes occurring within a well. We describe the design and test results of the mobile software and hardware well killing complex (MPAK GS). MPAK GS is capable of simulating fluid injection through the annular and tubing sections and can replicate well-killing operations using both forward and reverse circulation. This setup enables visual monitoring of each stage of the process inside the model well. We recorded the obtained data in digital form and used them to establish mathematical relationships between pressure measurements at various points in the well and the operating parameters. The obtained and proven dependencies can be used to develop a mathematical model of the hydraulic wellkilling program.
