Abstract
There is a need for improved efficiencies in the bitumen and heavy oil recovery and extraction industry. The present invention is directed to a method and system for integrating water between an in-situ bitumen recovery operation and a bitumen mining operation for improving efficiencies and synergies therebetween. A method of integrating water between a bitumen mining and extraction operation and an in-situ bitumen recovery operation comprises a) providing water associated with the bitumen mining and extraction operation; and b) directing the water, or boiler feed water or steam generated therefrom, to the in-situ bitumen recovery operation for use therein. Steam generated is used to assist in bitumen recovery at the in-situ facility. A basic system for integrating water between a bitumen mining and extraction operation and an in-situ bitumen recovery operation comprises a) a bitumen mining and extraction facility having a source of water;
b) an in-situ bitumen recovery facility; c) a transporter for transporting the water, or boiler feed water or steam generated therefrom, to the in-situ bitumen recovery facility for use in an in-situ bitumen recovery operation. The in-situ recovery operation may be a thermal operation, such as steam-assisted gravity drainage (SAGD), cyclic steam stimulation (CSS), or a derivative thereof. The integrated method and system of the present invention provide the potential to reduce water consumption, water waste, energy consumption, capital investment, operating costs and overall land footprint, compared with stand-alone in-situ recovery and mining and extraction operations and facilities. The integrated method and system of the invention also provide the potential for commercial development of smaller scale in-situ bitumen recovery operations.
b) an in-situ bitumen recovery facility; c) a transporter for transporting the water, or boiler feed water or steam generated therefrom, to the in-situ bitumen recovery facility for use in an in-situ bitumen recovery operation. The in-situ recovery operation may be a thermal operation, such as steam-assisted gravity drainage (SAGD), cyclic steam stimulation (CSS), or a derivative thereof. The integrated method and system of the present invention provide the potential to reduce water consumption, water waste, energy consumption, capital investment, operating costs and overall land footprint, compared with stand-alone in-situ recovery and mining and extraction operations and facilities. The integrated method and system of the invention also provide the potential for commercial development of smaller scale in-situ bitumen recovery operations.
