WATER PRODUCTION METHOD Russian patent published in 2006 - IPC E21B43/34 E03B3/06 

FIELD: water production from boreholes.

SUBSTANCE: method involves drilling production and injection borehole systems; penetrating borehole by perforation thereof; applying vibroacoustic pressure oscillations to formation, wherein the pressure oscillations are excited by acoustic borehole tools lowered in boreholes; producing water from boreholes. Injection borehole pipes are not perforated and are filled with working liquid. Acoustic oscillations are initially applied to production boreholes so that pressure in production boreholes preliminarily filled with fracturing liquid should be at least 2 times greater than formation breakdown pressure. Acoustic borehole device is located within perforation area. After crack opening water is lifted from production boreholes. During water lifting acoustic pressure oscillations are applied to formation through injection boreholes.

EFFECT: provision of water production in dry territories, increased economy and efficiency.
