Delivery of non-intrusive solution for ESP optimisation
Objectives
  • An operator with a large number of producing black oil wells had downhole Electrical Submersible Pump (ESP) systems with gas separation systems installed to augment production
  • The ESP systems were subjected  to higher gas rates and varying pressures from the initial design specification
  • The customer did not have individual well monitoring in place and therefore had no visibility on the well inflow performance and on the efficiency of the downhole separator
  • The customer was facing shutting down the ESP systems to reduce the production rate to avert catastrophically damaging the ESP and avoiding a costly work over
  • The customer approached Expro for an non-intrusive solution
Expro Excellence
  • Expro proposed utilising a non-intrusive methodology to monitor and provide reliable measurements
  • These measurements were taken at the wellhead without the need to modify the well configuration
  • Expro were able to measure intake pressure, Producing Bottomhole Pressure (PBHP) and Annular Gas Flow measurements directly at the surface wellhead in real time
Value to client
  • The customer received reliable measurements, which gave them insight into the pump and well inflow performance, giving the customer an understanding of how their well was performing
  • The annulus gas rate provided by Expro gave the customer an indication of the downhole separator efficiency
  • The customer was now able to access ESP and well performance monitoring, results were input to reservoir models and nodal analysis
  • The customer used this insight to increase pump and separator performance and maximise production from the well
  • Expro provided the customer with a non-intrusive solution from the surface.  There was no requirement to break pressure containment and surveillance was performed within one working day
