Abstract: A method for collecting a heated fluid from a fractured subterranean formation can include removing a fluid having a liquid phase from the fractured subterranean formation through a wellbore that is in fluidic communication with the fractured subterranean formation. The method can also include collecting from the wellbore the heated fluid having a vapor phase that is expelled from a low permeability rock matrix of the fractured subterranean formation. The method can also optionally include injecting an injection fluid having the liquid phase into the low permeability rock matrix of the fractured subterranean formation through the wellbore when a parameter falls outside a range of acceptable values.

Abstract: This disclosure provides embodiments of computer implemented methods, computing apparatuses, and other methods for determining reserves of a reservoir. For example, an embodiment of the computer implemented method includes receiving field data for a field that comprises a reservoir, wherein the field data includes pressure data and cumulative production data. The embodiment further includes generating normalized pressure values for a plurality of timestamps using time, the pressure data, and the cumulative production data. The embodiment further includes generating a normalized pressure graph, wherein the normalized pressure graph includes a normalized pressure curve of the generated normalized pressure values.
