Abstract (en)
[origin: WO2016145340A1] A method for performing a pressure buildup test in an evaluation zone of a well includes the steps of perforating the well in the evaluation zone to allow the flow of hydrocarbon fluids from the reservoir, deploying a pressure buildup test system into the evaluation zone, supplying the lift fluid via the coiled tubing to lift the hydrostatic pressure to lift the hydrocarbon fluids from the evaluation zone toward the surface, moving the packer to the set position, monitoring the pressure data in the evaluation zone, closing the shut-in valve when the stable state of the pressure data is reached, and measuring a buildup pressure in the evaluation zone using the pressure monitoring device. The pressure buildup test system includes a packer, a sub port, a coiled tubing, a shut-in valve, a pressure monitoring device, and a PLT.
