This book was released on 2018 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Gas condensate reservoirs constitute a significant portion of global hydrocarbon reserves. In these reservoirs, as bottomhole pressure falls below the dew point, liquid develops in the pore space. This results in the formation of a liquid bank near the wellbore region that decreases gas mobility, which then reduces gas inflow. Some gas condensate reservoirs have bottom aquifer drive, which also negatively impacts gas production. This research used a field case study to demonstrate an integrated workflow for forecasting well deliverability in a gas condensate field in Libya. The workflow began with the interpretation of open-hole log data to identify the production interval net pay and to estimate petrophysical properties. A compositional model was developed and matched to actual reservoir fluids. Transient pressure analysis was described and used to identify reservoir properties. Inflow performance relationships (IPRs) were analyzed using three types of backpressure equations. The workflow integrated all data in a numerical simulation model, which included the effect of bottom water drive. Sensitivity analysis was used to identify parameters with the greatest impact on future deliverability and recovery. The results provided in this case study demonstrated the importance of an integrated workflow in predicting future well performance in gas condensate fields with bottom water drive. The study demonstrated how to implement the workflow in managing or developing these types of reservoirs"--Abstract, page iii.

Download or read book Analysis of Capillary Pressure and Relative Permeability Effects on the Productivity of Naturally Fractured Gas condensate Reservoirs Using Compositional Simulation written by Bander Nasser Al Ghamdi and published by . 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 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas condensate reservoirs are one of the viable and less carbon-intensive natural gas systems for meeting the ever-increasing global energy demand. Complex fluid characteristics exhibited by gas condensate systems and the event of retrograde condensation as reservoir pressure depletes facilitate a multiphase flow regime. Unlike in the case of a dry-gas reservoir, the adaptation of Production Data Analysis (PDA) practices to model multiphase flow in gas condensate systems cannot be understated. The strong non-linearity of pressure-dependent fluid properties and a lack of a complete saturation-pressure relationship introduce inherent complications for PDA practices in such complex natural gas systems. Hence, this research aims to review a reliable and robust analytical modeling technique for multiphase flow and production data analysis in boundary-dominated gas condensate systems to assist in proffering effective production, development, and management strategies. A pivotal area of this research emphasizes a requisite to improve the current state-of-the-art approaches for multiphase pseudo-pressure calculations through the implementation of a reliable saturation-pressure relationship proposed by Tran (2022). The commonly used Constant Volume Depletion (CVD) test data fails to capture the actual behavior of multiphase flow in gas condensate systems. To corroborate Tran's (2022) methodology, further investigation into modeling multiphase flow and the incorporation of the improved saturation-pressure relationship also known as the Rescaled CVD method into the Unified Density-based approach for appropriate resource estimations, gas-oil ratio predictions, and flow rate predictions for multiple gas condensate case studies are presented in this study. Overall, the UDB-Rescaled CVD method demonstrates higher predictive accuracy and precision for a wide range of boundary-dominated gas condensate systems set to produce under constant and variable bottomhole pressure schedules.
