The analytical technique considers a single fracture opening and is used in a sensitivity analysis to evaluate the impact that rock/fluid parameters can promote on strain time histories. Moreover, advanced cases including multiple fractures failing in tensile or shear mode are simulated...

.... In this paper, we present progressive optimization (PO), a simulator-nonintrusive four-stage methodology to accelerate optimal search substantially in well-control applications. The first stage of PO comprises a global exploration of the search space using design of experiments (DOEs). Thereafter, in the second...

.... Compositional simulations are conducted that incorporate a tuned pressure/volume/temperature (PVT) model and a set of measured cyclic injection/compaction pressure‐sensitive permeability data. Markov‐Chain Monte Carlo (MCMC) is used to estimate the posterior distributions of the model uncertain variables...

Graham Summary The Todd and Langstaff (1972) mixing parameter ( ω ) is the most commonly used parameter in black oil reservoir simulators for modeling the effects of viscous fingering on a field scale, as their model is a useful alternative...

... pressure drop and oil production at steady state for different water‐injection rates can be used to derive relative permeability and capillary pressure from waterflooding. This is done in three ways. First, synthetic transient waterflooding tests are generated (using a core‐scale simulator), applying...

However, multiple physics applied on the matrix are generally incomplete in previous studies. In this study, we considered the comprehensive physics that occurred in the matrix including the effective...
