The workflows from both modules are then automated and thoroughly implemented as the first multiple-module workflow in this software package. This integrated workflow improves the quality of quantitative production...

... Abstract Accurate estimation of in-situ water saturation in unconventional shale reservoirs is critical for effective water production and management. Traditional resistivity-based water saturation calculation methods face challenges due to uncertainties in rock and fluid properties (e.g...

... Abstract Empirical decline curve analysis remains the primary tool for the estimation of ultimate recovery of unconventional shale wells, and correspondingly, the associated economic value. Yet, certain DCA parameters are difficult to determine directly from production data, especially early...

This study investigates the feasibility of CO 2 storage in depleted unconventional oil and gas reservoirs, with a focus on estimating capacity based on production data for major US basins, conducting rate transient analysis for injectivity and capacity of a single well, and examining microscale...

... Abstract An accurate bottom hole pressure estimation is critical for the correct evaluation of any unconventional shale reservoir as it generates the necessary input for production diagnostic plots (such as the Linear Flow plot and the Log-Log plot), Rate Transient Analysis and Numerical...

..., classical well testing is no longer a practical tool to estimate these parameters. Diagnostic Fracture Injection Tests (DFITs) are one of the few methodologies that allows estimation of reservoir transmissibility and pore pressure in unconventional reservoirs.

Nolte (1979) suggested a flowback rate between 1/6 to 1/4 of the previous injection rate and that it should be at a meaningful fraction of the in-situ leakoff rate. Nolte (1979) initially suggested picking fracture...
