The purpose of this project was to develop and apply a new concept for well completion involving ESP systems, tubing-conveyed perforating (TCP), drillstem testing (DST), and chemical treatment of the formation by using standard equipment and techniques. The concept was developed after identifying the opportunity to optimize operations in wells where the above equipment and operations are required.This paper summarizes practical experience gained during the development and deployment of this system.IntroductionDuring the completion process of a well, certain operations are performed to enable the well to produce by creating an unobstructed flow path for the oil and lifting it to the surface. This process is intended to realize actual production that measures up to the forecasted potential of the well.After a well is constructed, a communication tunnel is created from the casing into the reservoir through which formation fluids will flow into the well. For this purpose, one of the most effective techniques is tubing-conveyed perforating (TCP), a technology that consists of a set of tubing-deployed guns that are activated by a primer or firing head and detonate shaped charges. These charges create holes in the casing that allow formation fluids to freely flow into the wellbore.When formation characteristics such as permeability, skin, and reservoir pressure are uncertain, a drillstem test (DST) may be performed after perforating the well. With the implementation of high-accuracy pressure and temperature gauges, this testing method can help determine reservoir characteristics under production conditions. In wells that will not naturally flow, unpredictable results may be obtained. Because commercial production rates need to be guaranteed, techniques have been implemented such as using nitrogen to produce the well, which gives good results but is very expensive. Another technique for consistently delivering commercial production rates is to use an artificial lift production method like an electrical submersible pump (ESP) to increase the energy of the fluid at the bottom of the well to transfer them to the surface.Acid treatment is a stimulation process used to bypass a damaged area in the near wellbore region of the formation to increase the flow path and clean the perforations to increase production. This technique must be implemented after performing corresponding laboratory tests. One of the biggest disadvantages of using acid in the well is the aggressiveness of these fluids, making it impossible to perform matrix acidification when an ESP has been installed with a conventional completion configuration. Acids can attack both metal and elastomeric materials used in ESP systems.
