OBJECTIVES OF WELL TEST OPERATIONS
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.
