Abstract:
Water production from an oil and gas well has been a major problem for the industry in terms of reduction in HC production, loss of reservoir energy, equipment damages, handling issues at surface etc. Isolating the water contributing zone(s) has been a contest for the companies as most of the times it involves expensive rig workover jobs. Typically, a compromise has to be made over the HC production to avoid water influx till the time it is deemed necessary to carry out a workover job. Most recently extensive investments have been made in the R&D to look into thru-tubing workover options that would help in reducing the associated workover costs, substantially. Consequently, substantial advancements have been made in the field of Thru-tubing Engineering. This paper describes the complete well application and the challenges associated with this thru-tubing job, explaining the selection criteria for the most suitable Thru Tubing technological application. It then discusses the summary of the workover job and the eventual benefits the operators made out of this rigless workover.
