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.
