FIELD: oil and gas industry.
SUBSTANCE: invention is related to a method of well production optimisation. Intervals are selected in a deviated offshoot and drill-stem testing and borehole treatment is deployed. Then each interval is isolated in order to perform the required testing. The obtained testing data are evaluated in order to define respective recovery measures, which are implemented later by means of the drill-stem testing and borehole treatment.
EFFECT: provision of testing and treatment for the plenty of intervals in a horizontal hole during one running to the borehole.
