This book was released on 2009 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The developments of gas-condensate reservoirs are highly dependent on the thermodynamic behavior of the fluids in place. During the depletion of gas-condensate reservoirs, the gas condenses as the pressure of the reservoir reduces below the hydrocarbon dew point pressure, which introduces a liquid phase called retrograde condensate. In such conditions, the productivity experience a reduction in recovery due to the appearance of condensate near the production channels, which in turn reduces the overall flow of hydrocarbons to the surface. The phase behavior of the fluids in place impacts the production scheme of gas-condensate reservoirs, since the recovery of condensate is highly dependent on the changes in composition. In this study, the productivity of naturally fractured gas-condensate reservoirs is addressed using a compositional simulation model to examine the effects of capillary pressure and relative permeability on the recovery of gas-condensate fluids. Capillary pressure is a function of saturation and it controls the distribution of fluids in the pore spaces of a reservoir. The role of capillary pressure in the distribution of fluids in the reservoir can become more relevant in naturally fractured reservoirs, where the transport of fluids between the matrix and the fractures depends on the capillary pressure. In addition, the deliverability of gas-condensate reservoirs in such conditions is controlled by the transport properties, which are the relative permeabilities between the fluids in a pore-scale. Therefore, this study is devoted to evaluate the growth of condensate coating by examining different compositions (light/heavy) with the activation of the capillary pressure forces, while keeping the depletion rate constant, and deactivating the diffusion effect in the system. A compositional simulation model was utilized for the evaluation of the influence of fluid characteristics on the severity of condensate coating while assigning tight matrix permeability of 0.001 md, 1 psi/day for depletion rate, and zero capillary pressures. The analysis of the condensate coating on the edges of the matrix blocks lead to the conclusion that the saturation pressure point is controlled by the concentration of heavy components. The sooner the saturation pressure is reached, the sooner condensate appears and hinders the overall recovery of fluids. Using the same conditions applied to the different composition concentration while activating the capillary pressure effect at different pore size distribution indexes (1.5 to 7); the fluid distribution, movement, and recovery, had a similar behavior indicating that the capillary pressure had insignificant influence on the reservoir fluids behavior. On the other hand, the effect of relative permeabilities showed dependency on the amount of condensate content in the reservoir. The more condensation that takes place, the more influence is applied by the relative permeability curves. The major variable that enhanced the oil-gas relative permeability curve was the fracture parameter (ë) obtained by van Genuchten's (1980) to calculate the oil and gas relative permeabilities. Several values were used to address the fracture parameter to influence the position of the oil-gas relative permeability curve. As a result, it appeared that the influence depends on the amount of condensate content in the reservoir. The more condensation that takes place, the more influence is applied by the relative permeability curves.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During miscible gas injection for enhanced oil recovery, the composition of the fluids can change throughout the reservoir as the oil and gas phases develop miscibility. Miscibility improves oil recovery but adds difficulties in predicting the behavior of the flood. The fluid properties will change throughout the reservoir with regions of the reservoir exhibiting separate gas and oil phases, where in other regions the components form only a single phase. In particular, measuring and modeling relative permeability as these regions are traversed creates many challenges. One practical challenge is that in simulators each phase is associated with a relative permeability; this can create discontinuities when phases disappear across miscibility boundaries. These discontinuities can cause errors in the relative permeability calculations and sometimes crash the simulator. Some newer relative permeability models attempt to resolve these issues by changing the standard “oil” and “gas” method of phase labeling and instead labeling phases according to a physical property that is continuous and tied to composition, most notably the fluid density or Gibbs free energy (GFE). Ideally, a relative permeability model will be based on experimental measurements. There are several examples of two-phase relative permeability experiments in the literature, but far fewer three-phase experimental data to test models with. A handful of all relative permeability experiments focus on studying changes in relative permeability brought about by changes in fluid composition with increasing capillary number. However, there is also evidence to suggest that composition can impact relative permeability even at capillary numbers well below the capillary desaturation threshold. In this research, two-phase gas/oil core flood experiments were performed with ethane as the gas phase and equilibrated octane as the oil phase. Pressure was varied so that the composition (density and GFE) of the gas and oil were changing. The capillary number was kept low and constant to prevent capillary desaturation of the oil phase. The experiments were then repeated with an added residual brine phase to test the effect of composition with a third phase present. The results show that changing the density and GFE of the oil and gas phases in either two-phase or three-phase flow had no impact on the relative permeability curves. However, significant changes were observed when comparing two-phase to three-phase oil and gas relative permeabilities. When only gas and oil were flowing in the core, the oil phase formed a continuous layer on the pore surfaces. The addition of residual brine caused the oil to become non-spreading, reducing the relative permeability of both the oil and gas phases in the absence of a continuous layer of oil. These findings verify previous history-matched relative permeabilities in literature and show that phase connectivity is more significant than compositional parameters alone. The relationships between Corey parameters and compositional parameters (density and GFE) were also evaluated to determine when it is appropriate to use compositional models in reservoir simulation
