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.
