<p>The invention relates to the recovery of liquid or gaseous fluid media from wells, more specifically to methods for recovering residual nonrecoverable oil from depleted formations by a secondary pressure and the gasification thereof. The inventive method consists in naturally transferring compressed gas from lower gas-bearing beds to upper depleted oil-bearing stratums and creating a determined relation between gas and petroleum hydrocarbons. Said relation allows the residual non-recoverable oil in the stratum to be dissolved and afterwards recovered in the operational mode of the natural depletion of oil-and-gas condensate pools.</p> |
