Patent
·
OSTI ID:5751269
In a method and means for recovering viscous crude oil from individual wells, a dual type packer is run into a well bore on the depending end of a tubular pumping string for communicating with the well bore below the packer. A fluid pump is installed in this first string of tubing. A second string of tubing is run into the well through the packer and provided with a check valve below the packer. Hot gases are then injected into the well bore or circulated through the second string of tubing to dilute the viscous crude oil, which is removed from the well by the action of the pump in the first string of tubing.
