WebNov 14, 2024 · Summary. A series of shale gas adsorption and desorption experiments are conducted. Desorption and adsorption curves are not coincident, with the former located above the latter, which suggests that adsorption hysteresis also occurs in shale gas. Pseudodeviation factor (Z*) is revised to advance the material–balance equation (MBE) … WebJun 12, 2015 · The objectives of a material-balance analysis include: Confirming the producing mechanism; Estimating the original oil in place (OOIP) ... undersaturated oil reservoirs. This method is analogous to Cole’s popular method of plotting F/E gwf vs. G p for gas reservoirs. In theory, an active waterdrive is indicated if the plot varies appreciably ...

Convert all flowing pressures to … WebJan 1, 2015 · The flow material balance method is applicable only when the flow reaches boundary-dominated flow period. In this case, the flow reaches a steady or pseudo-steady state, and the pressures at all points of the reservoir drops at an identical velocity, as shown in Figure 9.1.We can also see that the change in average pressure of reservoir equals to … therapets edinburgh university

WebJun 17, 2024 · The flowing material balance (FMB) method uses flowing well head pressure, rather than shut in reservoir pressure, to estimate gas in place (GIP) and reserves at any stage of reservoir depletion. In addition, it can be applied to estimating permeability and skin of the reservoir and predicting production problems.
