Electrical Submersible Pump (ESP) SolutionESPs are often the lift method of choice for high volume, deviated, and deep wells. They efficiently produce volumes of over 1,000 BPD and require little maintenance and surface equipment. An ESP application summary is shown below:
With any ESP completion, operators are interested in the ways eP can extend the life of the pump. By extending the run life, operations benefit in two ways. Reducing down time of the pump increases the production of the well over a period of time and reduces the cost of replacing worn or damaged pumps. Beyond replacing pumps, there are several common problems encountered when using ESPs.
eP's total solution provides wellsite intelligence, historical references, and remote optimization. At times, the VFD solution can react to changing fluid levels and return to normal operations without the operator knowing that there was a problem. With the remote terminal unit (RTU) storing the short term data and the remote software collecting, trending, and providing analytical displays of that data, the user is aware of temporary changes in the system. These changes can be compared over time to identify trends that provide a method to predict potential problems and take proactive action to avoid impending expensive repairs. eP's ESP solution provides intelligent control at the
well head as well as monitoring, analysis, and control at the desktop.
The result is improved ESP performance and increased profitability. Wellsite Intelligence with the Electrical Submersible Pump (ESP) Solution

The software provides much more than just a way to track problems. It analyzes pump performance and does ESP design. Sophisticated analytical tools allow the user to watch indications of well and pump changes. By tracking the well testing results along with the pump and well curves, the user can quickly identify the source of decreased production as reservoir changes, pump wear, or blockages occur. The software user is able to use real-time data and perform detailed pump analysis at each stage of the pump. With that information, the analyst can immediately see if each stage is in upthrust or downthrust. That allows the operator to make immediate changes to the operation of the system and more importantly, allows for better designs in the next pump placed in the hole. The design engine provides a "best fit" pump for a range of operating conditions utilizing an online pump catalog and integrated inflow performance models. Design problems associated with CO2 and gas are handled with the miscible fluid and multiphase flow calculations. "What if" scenarios allow the analyst to choose between pump designs based on criteria such as electrical cost per bbl or pump efficiency. The solution provides a way for operators to decrease failure rates significantly and ultimately increase production and profits for the field. eP Electrical Submersible Pump (ESP) Solution ComponentsHardware
