Unfortunately, the final updated models may deviate substantially from the initial RTA estimates; moreover, specific information regarding the flow regimes is not incorporated directly into the history-matching step. In this paper, a new assisted history...

... presents a detailed analysis of the issue, and investigates the conditions under which data beyond the MPT should be ignored. Three different reservoir models have been used with associated pertinent flow regimes to cover and demonstrate the subject. Specifically, it addresses questions such as: What...

.... We have studied the behavior of the EFR (Enhanced Frac Region) model and show how it deviates from the Compound Linear Flow type curves. We demonstrate that what is often considered to be linear flow is only a transition between two flow regimes and results in misinterpretation of the linear flow...

... way. These results can be used to seed analytical models for subsequent history matching and forecasting. Diagnostic methods currently used for interpreting performance of multi-stage horizontals are based on identifying specific flow regimes using specialized plots (eg- square root time and flowing...

.... Results from this study shows that pressure normalization could potentially be used to identify the flow regimes in LRS reservoirs, which is especially true for rate restricted fields. We also observed that the production characteristics of LRS gas condensate reservoirs are highly variable, possibly due...

... flow regime is observed to be dominant in pore scale. As a result, permeability changes with pore pressure. Traditionally, permeability is measured at various mean pore pressures and the data is used to extract the Klinkenberg or absolute permeability. However, it has been shown recently...

... Abstract Decline curve analysis in unconventional reservoirs is challenging due to the extremely low reservoir flow capacity coupled with the completion techniques and production practices used to achieve economic rates. The primary flow regimes for these wells include transient bilinear flow...

... . In addition, the non-Darcy flow is found to impose a significantly impact on the early-stage bilinear/linear flow regime, resulting in an additional pressure drop that is similar to lowering the fracture conductivity. The pressure response can be classified into two categories by a penetrating ratio of 0.5...

... linear flow). As a result, without careful data diagnosis prior to analysis, flow regimes could be falsely interpreted, which results in misleading interpretation of well performance, and c) outliers are accentuated, resulting in a false interpretation of apparent validity. In this work, a new...
