SYSTEMS AND METHODS FOR OPTIMISATION OF THE BOREHOLE CREATION IN THE SHALE FORMATION Russian patent published in 2017 - IPC E21B7/06 E21B43/26 E21B47/12 

Abstract RU 2622280 C2

FIELD: oil and gas industry.

SUBSTANCE: the method contains determination of the first planning location (107) of stimulation within the formation at least partially based on the specified model of the formation. The borehole in the formation may be drilled using the downhole tool (204) with blocks (206) LWD / MWD. To update the formation model the measurements in the real time mode are used and determining the alternate location (301) of stimulation. IGV (inlet guide vane) equipment is isolated from the equipment (205) of stimulation by installing the disposable balloon at the installation location of the balloon between the block LWD and stimulation equipment. The second stimulation location can be determined based on the data obtained from the IGV after the formation inflow intensification in the alternative location of the stimulation.

EFFECT: reduced time of the transaction.
