METHOD AND SYSTEM FOR INTERPRETATION OF SWABBING TESTS USING NON-LINEAR REGRESSION Russian patent published in 2013 - IPC E21B43/25 E21B47/06 

Abstract RU 2474682 C2

FIELD: oil and gas industry.

SUBSTANCE: method for increasing the extraction in the reservoir bed involves the swabbing tests in the pipe at some depth. The pipe is arranged in the well shaft. Some part of the well shaft is locate inside the reservoir bed. From time to time, pressure is measured in lower part of the pipe using a pressure gauge in order to obtain a variety of pressure measurements during the swabbing test. Pressure gauge is attached to inner wall of lower pipe part. Variety of velocities of the fluid flowing from reservoir bed is determined through perforations made in the well shaft to the pipe using the flow velocity equation and variety of pressure measurements.

EFFECT: improving the information acquisition efficiency.
