... for superposition and multiphase flow effects have been studied extensively in the past. Analytically correcting for the combined effect of both superposition and multiphase flow at the same time ( multiphase superposition ) is not possible, as one needs to know saturations and PVT properties as a function of space...

... of saturation and pressure change calculations, logarithmic gridding was employed. As noted earlier, Haqparast et al. (2024) assumed a constant fracture pressure during the flowback period; however, pressure changes do occur during this stage of DFIT-FBA tests for real field cases. Therefore, to relax...

..., such as porosity, saturation, well spacing, and fracture designs, to evaluate their impact on the b-factor. In theory, the b-factor changes with time and flow regime. Specifically, it transitions from a value of 2 during linear flow to less than 1 during boundary flow. However, in practice, a constant b-factor...

It is shown that initial water saturation and fracture/matrix compaction tables represent the top-heavy hitters for estimated ultimate recovery (EUR). We then consider two production scenarios (single vs. multiple well production...

... condition. Therefore, the irreducible water saturation after flowback is higher, resulting in lower effective oil permeability. Introduction The development of hydraulic fracturing technologies has dramatically transformed the exploitation of unconventional hydrocarbon resources, such as shale and tight...

... 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 Fluid flow in the pore network depends on the preferential movement of different fluid phases. To understand the preferential movement of different fluids in the reservoir, saturation-dependent petrophysical properties such as relative permeability are critical. Therefore, saturating...

For example, it is well known that water-saturated rocks have higher velocities than rocks with dry pore spaces and different types of oil/gases present in the rocks (Hamid and Yuefeng, 2014). So, the presence of CO 2 in the CCS projects will significantly affect...
