Results of Exploitation of Precarpathian Fields by Branched Horizontal Wells.

The results of exploitation of low-permeability oil deposits in the late stage of their working by means of branched horizontal wells are presented, citing the Borislavskiy and Dolinskiy fields in the Precarpathian region as examples. It is shown that the use of branched horizontal wells leads to an increase in the oil output on fields with low-permeability and discontinuous collectors and also greatly reduces the number of wells required for drilling out deposits.
