Abstract: A methodology for modeling oil/water or gas/water paleo zone reservoir properties for hydrocarbon management is provided. Reservoir simulations in a subsurface, such as in an oil region bounded by a gas cap and a water region, may use an initial reservoir simulation model. The methodology determines one or both of the oil/water or gas/water interfaces to honor the equilibrium state of the subsurface. The current configuration of the subsurface may be the result of one or more processes, such as a drainage process and an imbibition process, each of which have different associated curves reflecting the physical phenomena of the fluid/rock properties in the subsurface. The methodology honors the physical process, including comporting with the different curves and with the available data, in order to determine the current state of the subsurface, including one or both of the oil/water or gas/water interfaces.

Abstract: A methodology using an interwell connectivity model for hydrocarbon management is disclosed. The interwell connectivity model may include interwell connectivity metrics indicative of fluid interconnectivity amongst pairs of wells and may be used as predictive or prescriptive for enhanced oil recovery (EOR). As predictive, the interwell connectivity model may be used to determine an effect of gas injection into the reservoir on one or more aspects of EOR, such as reservoir pressure or production rates. As prescriptive, the interwell connectivity model may be used to improve or optimize various stages of EOR, such as during drilling or construction of the extraction site, during primary depletion, or during one or more huff-and-puff cycles.
