WATER-INTAKE CAPACITY BALANCING METHOD OF TWO WELLS Russian patent published in 2012 - IPC E21B43/36 

FIELD: oil and gas industry.

SUBSTANCE: during balancing of water-intake capacity of two wells there chosen is a pair of wells with low water-intake capacity and high water-intake capacity; working medium is pumped to the well with low water-intake capacity, drained from the well and pumped to the well with high water-intake capacity. As working medium there used is water solution of surface-active substance with density of more than 1.17 g/cm³ and solvent of paraffin. After the working medium is pumped to the well with low water-intake capacity, process exposure takes place, and after the working medium is drained from the well with deposits removed from the well in the form of viscous emulsion, the viscous emulsion is pumped to the well with high water-intake capacity; geophysical investigations are performed on both wells and wells are put into operation.

EFFECT: increasing balancing efficiency of profile of the well water-intake capacity.
