LAYOUT FOR TESTING GAS CONDENSATE OR OIL WELLS

 

Following important data & samples to be obtained from well test :

  • Gas production rate in MMSCF/D.
  • Oil or Condensate production rate in barrels per day.
  • B&W percentage of crude.
  • Gravities of oil , gas & water
  • Salinity of water with further compositional analysis if possible.
  • Viscosity of condensate or crude.
  • Pourpoint of condensate or crude, determined from fresh wellhead samples.
  • Rough wellhead composition of produced gas, including H2S,CO2, CO&N2 content.
  • Bottom hole pressures, build-ups and draw-downs.Bottom hole temperature.
  • Accurate recording of surface pressures, temperatures and flow data versus time.
  • Separator gas samples, Oil samples , under pressure
  • Bottom hole PVT samples.

Above introductory figure shows typical well testing layout for a very complete set of equipment. The equipment requirements and design for successful well testing obviously vary according to the specific requirement of operators.
