Challenge

Geothermal wells in Germany are operated under strict monitoring regulations to ensure health, safety, and environmental guidelines are met.
  • Downhole gauges monitor ESP performance but run a high risk of fault due to downhole operating conditions
  • Operators need alternatives to ensure compliance without expensive well interventions each time a gauge malfunctions

Solution

InteLift Well Manager System Virtual PIP calculation presented in real time

  • Less than 2% error when compared with downhole gauge readings
  • An increase in error is used to diagnose possible adverse well conditions

Result

  • Operators fulfill government requirements without unplanned interventions
  • No need to incur additional expenses installing a backup gauge or surface hardware
  • ESP run life increased
  • Geothermal plant uptime increased

Overview

German geothermal wells provide energy for power generation and heating for homes and businesses. To ensure the highest level of safety for health and the environment, local authorities require meticulous monitoring and advanced tools to ensure efficient operations. Downhole gauges provide a wealth of information but are affected by harsh well conditions, including high wellbore temperatures and scale, which can affect performance or cause a short run life. When there are issues with a gauge, operators need an alternative that allows them to comply with government regulations without pulling the well to replace current downhole equipment.

Challenge

PIP is a key diagnostic for the ESP system’s health and the wellbore’s integrity. Local governmental authorities require continuous real-time PIP values, but when the downhole gauge is faulty or fails, the well must be pulled unless there are alternatives. Hardware solutions on the surface can calculate PIP but are often expensive, require personnel to install, calibrate and maintain, and they can have a 20-30% error rate.

Solution

Summit ESP’s real-time calculated Virtual PIP App from the InteLift Well Manager System’s industrial internet of things (IIOT) device considers well conditions, equipment specifications, and past performance to accurately calculate PIP with less than 2% error when compared with downhole gauge readings. Virtual PIP can also evaluate the current operating point and compare it to the best efficiency point.

Result

With this innovative technology, geothermal operators can run ESPs longer without sensor readings and unplanned interventions; operators can plan equipment replacement with ample time to minimize unnecessary downtime. The technology can also be used with monitoring services to model well conditions and equipment performance to determine if proactive actions can be taken to improve uptime, equipment reliability, or increase production. Finally, and most importantly, with InteLift Well Manager System’s Virtual PIP, operators can fulfill the governmental authorities’ requirements without extra hardware or maintenance expenses.
