The article presents key data of well interference testing at Yurubcheno-Tokhomskoye oil-gas-condensate field. Pioneering estimation of two zones interference is carried out. It is shown that the investigated part of Yurubcheno-Tokhomskoye field presents one hydrodynamic system. According to interference testing data carbonate reservoir matrix does not contribute to fluid filtration.
