Solar Calciner Enhanced Oil Recovery

摘要

A method of supplying crushed alkaline carbonate from a carbonate resource to a first calcining site having a design calcining capacity; solar calcining crushed carbonate within a prescribed carbon dioxide (CO2) delivery distance from a first enhancement location within a first hydrocarbon resource, whereby generating CO2 with a local CO2 generating capacity and an alkaline oxide; forming a first enhancing fluid comprising generated CO2 and delivering it into the first enhancement site having an injector well weighted first enhancement location, whereby mobilizing hydrocarbon in the first enhancement site; producing a produced fluid comprising mobilized hydrocarbon and enhancing fluid; recovering liquid hydrocarbon from the produced fluid; wherein the prescribed CO2 delivery distance is less than 67% of a remote CO2 delivery distance, to the first enhancement location from a remote calcining site having an equal or greater design calcined CO2 generating capacity. Then solar calcining CO2 to enhance a second site.

1. A calcining-EOR method of enhancing hydrocarbon recovery, using crushed carbonate having carbon dioxide (herein CO2) compounded with an alkaline-earth or alkali oxide, comprising:
supplying crushed carbonate from a carbonate resource to a solar first calciner at a first calcining site having a local design solar calcined CO2 generating capacity; calcining the crushed carbonate at the first calcining site located within a prescribed solar CO2 delivery distance from a first enhancement location at a first enhancement site within a first hydrocarbon resource; forming a first enhancing fluid from captured CO2 comprising a portion of the solar generated CO2; injecting a portion of the first enhancing fluid into the first enhancement site, through enhancement injector wells;
whereby mobilizing hydrocarbon in the first enhancement site having an enhancement injector well weighted first enhancement location; producing a produced fluid from the first enhancement site; and recovering a liquid hydrocarbon from the produced fluid; wherein the prescribed solar CO2 delivery distance is less than about 67% of a remote CO2 delivery distance to the first enhancement location from a remote calcining site having an equal or greater remote design calcined CO2 generating capacity than the local design solar calcined CO2 generating capacity.
