Embodiment Construction

Water Recovery (Recycle) Invention:

[0022]The following disclosure describes a process methodology, whereby Slop Oil generated as byproduct in the SAG-D Very Heavy Oil (Bitumen) production process is treated with select chemicals to separate and recover water, solids, and oil from the slop oil emulsion.

[0023]The process preferably involves the following steps:

[0024]mixing a first quantity of water with a first quantity of a first chemical blend to create a water / chemical mixture;

[0025]heating and stirring the water / chemical mixture (preferably for about 10-30 minutes until the mixture reaches about 50-70 degrees C.) (while not preferred, one could heat first to the desired temperature, then stir);

[0026]adding to the mixture SAG-D slop oil to create a water / chemical / slop oil mixture;

[0027]heating and stirring the water / chemical / slop oil mixture (preferably for about 30-60 minutes until the mixture reaches about 50-100 degrees C.) (while not preferred, one could heat first to the desir...

Abstract

A method of treating slop oil and slops from the SAG-D (steam assisted gravity-drainage) very heavy oil-bitumen crude oil production in such locations as Alberta and Saskatchewan provinces in Canada, Russia, Venezuela, Saudi Arabia, and Kern County, Calif., involves mixing the slop oil and slops with chemicals to help separate out water from the slop oil and slops.
