INNOVATIVE TECHNOLOGIES OF PRIMARY PENETRATION OF OIL DEPOSITS WITH ABNOMALLY LOW FORMATION PRESSURE IN CAVERNOUS FRACTURED RIPHEAN RESERVOIRS OF YURUBCHENO-TOKHOMSKOYE OIL AND GAS FIELD
The first practical experience of horizontal drilling in complex Riphean carbonate reservoirs with abnormally low formation pressure at the Yurubcheno-Tokhomskoye oil and gas field and the practices to combat fluid loss led the authors to the conclusion that the traditional technology of penetrating productive formation is not applicable. A new innovative technology of primary opening is proposed.
