Chemical that reacts with CO2 for extra oil production

Chemical that reacts with CO2 for extra oil production

Chemical that reacts with CO2 for extra oil production

(OP)
Hi to everybody,

We produce 12 API oil by injecting CO2 into the reservoir. we wonder if we inject a chemical that reacts with CO2 bringing heat what will happen? I mean, we can get extra oil by decreasing oil viscosity with this heat.

Does anyone help me with this subject ?!

Thank you for your consideration !

RE: Chemical that reacts with CO2 for extra oil production

I always thought that the CO2 injection was to lower the oil's viscocity having the CO2 act as a solvent. This is achieved by injecting the CO2 at supercritical conditions.
Unless I am mistaken, the solvent action should be more efffective than lowering the viscosity with temperature.
If you react your CO2, what are you going to use as a solvent to fluidize the oil?

RE: Chemical that reacts with CO2 for extra oil production

since CO2 is already one of the lowest energy molecules, sorry.  Do you realize that when CO2 contacts oil, there is a heat increase from the heat of solution?  But, the background rock absorbs it with little if any net temperature increase.

RE: Chemical that reacts with CO2 for extra oil production

I thought that typically when a gas dissolved in a liquid, the temperature of the liquid went down...  do I have that backwards, or is CO2 a special case?
