Electrical submersible pumps could be installed in four different production environments where the criteria for the design changes as fluid properties and well conditions change. In this article, four basic design types of ESP’s will be presented.
The basic designs will change accordingly and will mainly depend on:
Baker Hughes Centrilift AutographPC ™ is an artificial lift and application simulation software. It’s a powerful tool to give a comprehensive and user-friendly system design. This software can be used to design production systems, including: electrical submersible pumping (ESP) systems; electrical submersible progressing cavity pumping (ESPCP™) systems; rod-driven progressing cavity pumping (RDPCP™) systems; horizontal surface pumping (HPump™) systems; and gas lift systems, etc.
Each system installation is unique and with this software, all the well information, including production characteristics, fluid properties and well conditions, can be entered during the initial design phase to produce the optimum solution for each sizing.
Once installed and launched, Design Modes Screen, shown in the following screenshot, appears. Design Modes screen has been added to AutographPC since July 12, 2017. This is the screen where the user can select a design mode and start a new sizing program.
This article walks through the suggested nine step procedure for selecting and designing an electric submersible pump. This nine step procedure for ESP design is a basic hand-design of simple water and light crude oil. For more complicated well conditions, such as high GOR, viscous oil, high-temperature wells, etc. a number of computer programs are available to automate this process.
As detailed in the article “Step 1: Basic data ”, step 1 of the nine step design procedure is the most important step because all the others design steps will depend on the basic data selected in this step.
In this example, a high water cut well is considered. This is the simplest type of well for sizing submersible equipment.
