• High gas-to-liquid ratio (>3,000 SCF/STB)
  • Gas slugging
  • Increased oil production 48% from 169 BOPD to 250 BOPD
  • Increased drawdown 40% from 336 psi to 200 psi pump intake pressure
  • Reduced motor temperature from 176°F to 168°F
  • Improved natural gas separation to reduce free gas in the pump

Case study details

A horizontal well in the Delaware Basin’s Bone Spring reservoir was experiencing continual gas slugging. The operator had been using an electrical submersible pumping (ESP) system with a tapered pump design to handle the gas into the pump, but this system configuration did not sufficiently draw down the wells. The operator wanted to improve the well’s performance and increase its oil production by increasing the drawdown.
