Abstract: A method and system for both enhancing oil recovery of a reservoir and permanently sequestering carbon dioxide (CO2) is described. The method includes dissolving CO2 in a base fluid at a surface location of an injection formation, forming a dense CO2-brine solution, introducing the dense CO2-brine solution into an injection well, accumulating a volume of the dense CO2-brine solution in a structural low, displacing a native formation fluid from the injection well, increasing a fluid drive pressure from the injection well to a producing well, and displacing hydrocarbons of the producing well. The system includes an injection system in fluid communication with an injection well, a production well of the hydrocarbon production formation, and a dense CO2-brine solution that has a density greater than a native formation fluid of the injection formation.

Abstract: Provided herein are methods and apparatus for collecting and preserving core samples from a reservoir. In some embodiments, a method includes obtaining core samples from a reservoir using a rock and fluid sampling tool and depositing the core samples in a vessel filled with a hydrogen-free fluid such that a portion of the hydrogen-free fluid is displaced by the core samples and the core samples are immersed in the hydrogen-free fluid. The method also includes transferring a gas into the vessel to occupy a space in the vessel and sealing the vessel via a cap on an end of the vessel. Methods of analyzing the core samples core samples collected from a reservoir and a rock and fluid sampling tool are also provided.

Abstract: A method to perform a field operation of an unconventional reservoir is disclosed. The method includes selecting, from rock samples and based on test reports of corresponding companion rock samples, selected rock samples representing rock characteristics of formation zones in the unconventional reservoir, performing, using a rock sample test apparatus, a sequence of rock sample test cycles on each selected rock sample to generate rock sample test results, generating, based on the rock sample test results, a ranking of the selected rock samples representing enhanced oil recovery (EOR) potential of the formation zones, selecting, from the formation zones and based on the ranking, a target formation zone having an EOR potential meeting a pre-determined criterion, and performing, based at least on the EOR potential of the target formation zone, the field production of the unconventional reservoir.
