FIELD: oil and gas industry.
SUBSTANCE: method includes stress inducing in formation around well shaft in order to generate in it some special feature related to induced stress. Measurements presenting well shaft geometry are performed using assembly of drilling string bottom rotated in well shaft, which geometry presents induced stresses in formation. Creation of well shaft image based on its geometry measurements. Evaluation of azimuth variation of induced voltage in formation by well depth. Change of parameter of drilling mode for assembly of drilling string bottom using evaluation of azimuth variation of induced voltage in formation by well depth.
EFFECT: using data obtained in real-time mode, checking stress model for certain region, so that the path may be corrected constantly for achievement of optimum ratio with measured characteristics of stress for this region.
