METHOD OF WELL DEVELOPMENT Russian patent published in 2013 - IPC E21B43/25 

FIELD: oil and gas industry.

SUBSTANCE: in process of well development a pipe string with a packer and a valve is placed in a well, and the valve is capable of opening in the pipe string, the packer is installed, swabbing is carried out along the pipe string until inflow of reservoir products appears, the liquid level in the string is measured with a swab, the valve is opened, the packer is stripped, the pipe string is lifted, and the underground equipment is lowered. The bottom of the pipe string is placed below the perforation interval by 0.8-1.2 m, the annular space is filled with a killing fluid with density and in the volume sufficient to pull pressure at a bottomhole, which is more than the bed pressure, actions are organised, which eliminate overflow of bed fluids from under the packer into the annular space.

EFFECT: elimination of reservoir product exhaust from a well and reduced contamination of a well bottomhole.
