FIELD: oil and gas industry.
SUBSTANCE: method and system for planning and/or drilling of boreholes is suggested with stages whereat data are obtained on position of the first borehole, at that data are received by means of computer system; reading of data on position of the adjacent borehole; reading of data on fracturing diameter for the adjacent borehole; calculation of the first uncertainty for the first borehole position; calculation of the second uncertainty for the adjacent borehole position considering data specifying the position and diameter of fracturing; proximity index is generated for position uncertainty values. Computer system and energy-independent machine-readable medium are also suggested for implementation of the above method.
EFFECT: preventing direct or indirect crossings of boreholes.
