1. A method comprising:
acquiring a core sample from a first reservoir of interest; wherein the first reservoir is producing hydrocarbons at a first recovery rate;
performing, by a core flood apparatus, a coreflooding study comprising a plurality of coreflooding simulations using the core sample disposed in the core flood apparatus;
performing, by a computer processor and using a coreflooding simulation model, a reservoir simulation study on the first reservoir using the coreflooding study;
adjusting, by the computer processor, a core flood fluid based on the reservoir simulation study to form an adjusted treatment fluid that produces a second recovery rate from the first reservoir;
wherein the second recovery rate is greater than the first recovery rate; and
performing, using an injection well, an injection operation of a reservoir using the adjusted treatment fluid.
