Reservoirs bearing retrograde condensate behave much differently than oil and dry gas reservoirs. This difference is due to the dropout and accumulation of the liquid condensate during gas production. At this point, the gas expands isothermally near the wellbores as the bottom hole pressure decreases below the reservoir dew point pressure. In addition, the thermodynamic behavior of the gas condensate mixture which affects the depletion and production of these reservoirs results in complex in situ flow behaviors that affect fluid recovery. However, very few studies have been focused on elucidating the displacement physics of retrograde condensation at the pore scale and in natural porous media. To address these research shortcomings, two groups of systematic depletion experiments were performed on two individual miniature Fontainebleau sandstone core samples using a three-phase coreflooding system integrated with a high-resolution micro-computed tomography scanner. Both experiments were performed to investigate the impact of depletion rate and water saturation on condensate nucleation, growth, accumulation, and mobilization. The group of tests in the first experiment were conducted at different pressure decline rates while the core was initially fully saturated with a single-phase gas condensate mixture. In the second experiment, the sets of depletion tests were carried out at identical pressure decline rates and after establishing different levels of initial water saturation. This study reveals that at the onset of condensation, slightly below the dew point pressure, discrete nonuniform nuclei of condensate formed in the pore throats and crevices. At a higher pressure drawdown rate, the dropout, growth, and accumulation of condensate increased significantly. As the pore pressure continued to decrease, the condensate droplets became connected through wetting layers while the large gas clusters continuously fragmented into smaller globules with reduced hydraulic connectivities. This caused the condensate saturation to increase and resulted in the occurrence of condensate-to-gas imbibition displacements, i.e., snap-off and piston-like events, and the ensuing trapping of the gas phase in the pore space. This effect was significant at a higher depletion rate. Re-injecting the gas phase did not completely remediate condensate banking through the evaporation of the condensate phase due to the mass accumulation and capillary retention of the liquid in the pore space. Furthermore, the presence of water in the pores resulted in a shift in the dew point pressure that impeded the initial dropout and growth of the condensate. In addition, gas expansion and the monotonic increase in condensate accumulation occurred at decreasing pore pressures. This enhanced a chain of displacement events including gas-to-brine/condensate and condensate-to-gas/brine displacements and the consequent reduction in brine saturation in the pore space. These findings provide in situ experimental evidence of retrograde condensation in natural porous media with direct implications for the development of gas condensate reservoirs through pressure maintenance, and condensate-to-gas ratio (CGR) estimations in the presence of water saturation.

PVT properties are necessary for reservoir/well performance forecast and optimization. In absence of PVT laboratory measurements, finding the right correlation to estimate accurate PVT properties could be challenging. PVT Property Correlations: Selection and Estimation discusses techniques to properly calculate PVT properties from limited information. This book covers how to prepare PVT properties for dry gases, wet gases, gas condensates, volatile oils, black oils, and low gas-oil ration oils. It also explains the use of artificial neural network models in generating PVT properties. It presents numerous examples to explain step-by-step procedures in using techniques designed to deliver the most accurate PVT properties from correlations. Complimentary to this book is PVT correlation calculator software. Many of the techniques discussed in this book are available with the software. This book shows the importance of PVT data, provides practical tools to calculate PVT properties, and helps engineers select PVT correlations so they can model, optimize, and forecast their assets. Understand how to prepare PVT data in absence of laboratory reports for all fluid types Become equipped with a comprehensive list of PVT correlations and their applicability ranges Learn about ANN models and their applications in providing PVT data Become proficient in selecting best correlations and improving correlations results
