Abstract: A methodology for modeling multi-well communication considering multiple flow regimes for hydrocarbon management is disclosed. Understanding well communication scenarios in unconventional reservoirs may assist in assessing hydrocarbon asset development planning. Typically, well communication is determined by using a suitably-designed interference test, wherein the observation well is kept closed and the choke of a neighboring signal well is manipulated, with the resulting deviation in the pressure trend being used to determine the well communication. The interference test is not suitable due to requiring wells to be closed and to being applicable to only certain types of wells. Thus, a producer-producer connectivity model is used to analyze well communication and to quantify well communication strength. Such as connectivity model may use production data (not requiring wells be kept closed), does not require the building of a reservoir model, and may consider the simultaneous interaction amongst multiple wells through time.

Abstract: A method involves performing an enhanced oil recovery (EOR) operation. The method includes injecting a gas stream into a well via a first channel. The method also includes injecting enhanced oil recovery chemicals (EROCs) into the well via a second channel. The second channel is different from the first channel. An end of the first channel and an end of the second channel are positioned to facilitate static mixing of the gas stream with the EROCs to form an enriched gas stream in a subsurface region. The enriched gas stream facilitates the EOR operation.

Abstract: A method involves detecting parameters corresponding to a hydraulic connection between wells in a reservoir. Such method includes injecting carbonated water into a CO2 injection well. The method further includes identifying a presence of the carbonated water around a CO2 recipient well. The method also includes determining at least one parameter corresponding to the hydraulic connection between the CO2 injection well and the CO2 recipient well based on the presence of the carbonated water around the CO2 recipient well.
