... reservoirs. However, unconventional reservoirs (such as shales and tight sands) are typically used in transient linear flow during most of their production life. Depending on the distance between the fracture stages, this transient flow typically transitions into the fracture-interference flow regime, where...

... of the synthetic data set used to demonstrate our MVA workflow and scatter plots of the target (or dependent variable) vs. each of its correlated independent variables in the data set. Hydrocarbon production from unconventional reservoirs has a significant impact on the economics and geopolitics...

... 3 2022 11 8 2022 Copyright © 2022 Society of Petroleum Engineers The Duong model was introduced specifically for unconventional reservoirs with very low permeability and fracture dominated characteristic in production line ( Duong 2011 ). The model is based on one empirically...

...Hui-Hai Liu; Jilin Zhang; Feng Liang; Cenk Temizel; Mustafa A. Basri; Rabah Mesdour Summary Prediction of well production from unconventional reservoirs is often a complex problem with an incomplete understanding of physics and a considerable amount of data. The most effective way for dealing...

...Ji Soo Lee; David Jacobi; Zainab Alnajar Summary Rock strength is seldom considered important by the hydrocarbon industry to help monitor the drilling progress, evaluate wellbore stability, guide well completions, or predict the success of hydraulic fracturing in unconventional reservoirs...

... of pressure interference (MPI) in unconventional reservoirs, which commonly demonstrate a generalized, power‐law pressure response that is different from radial or linear flow. The examples presented in this paper are for wells from the Permian Basin Wolfcamp Shale. Under the framework of power‐law behavior...

...‐injection EOR in unconventional reservoirs using a fast‐marching‐method (FMM) ‐based flow simulation. The FMM‐based simulation uses the concept of diffusive time of flight (DTOF). The DTOF is a representation of the travel time of pressure‐front propagation and accounts for geological heterogeneity, well...

...W.–C.. –C. Chu; N. D. Pandya; R. W. Flumerfelt; C.. Chen Summary In unconventional reservoirs, the application of many rate–transient–analysis (RTA) techniques relies heavily on the identification and analysis of the linear flow regime, which is characterized by a ½–slope on a log–log plot of Δ p...

...Rafael Wanderley de Holanda; Eduardo Gildin; Peter P. Valkó Summary Analytical single-well models have been particularly useful in forecasting production rates and estimated ultimate recovery (EUR) for the massive number of wells in unconventional reservoirs. In this work, a physics-based decline...

..., hydrocarbon-rich shale formations: viscous flow in high-permeability fracture networks and diffusion-dominated flow in the low-permeability matrix with high oil saturation. Improving hydrocarbon transport (and technically recoverable resources) in unconventional reservoirs relies on our ability to enhance...

... strategy can indirectly influence later go/no-go decisions. Reservoirs are appraised by drilling and producing wells. In unconventional reservoirs, these wells represent a small subset of possible wells that could be monetized if the decision were made to develop the reservoir (i.e., the appraisal wells...

...Ilkay Uzun; Basak Kurtoglu; Hossein Kazemi Summary In unconventional reservoirs, production data are generally analyzed by use of rate-transient techniques derived from single-phase linear-flow models. Such linear-flow models use rate-normalized pressure, which is pressure drop divided by reservoir...

... if the best 3-month average or the initial production rate of the well is already known or estimated. The results show that this alternative approach is easier to use, gives a reliable EUR, and can be used to replace the traditional decline methods for unconventional reservoirs. The new approach is also able...
