“…Table 2 shows the fluid's main properties and the respective empirical correlations used for the PVT analysis. [1,23,[30][31][32][33]. The main characteristic of the bubble pressure determines the highest pressure when the first gas bubble is released.…”

“…The GOR property establishes the relationship between the gas and oil produced. On the other hand, dead oil viscosity is based on the value of the viscosity of gas-free oil at standard conditions, while saturated oil viscosity is the value of the viscosity of crude oil at bubble pressure and reservoir temperature conditions [33].…”

A reservoir behaviour's characterisation is determined by analysing the fluids' physical properties, reported in Pressure, Volume and Temperature (PVT) tests. These tests are performed in the laboratory or are estimated by mathematical correlations with the well's basic properties. The eastern basin of Ecuador is considered a hydrocarbon zone, and the analysis of the physical properties of the fluid from oil wells is essential. The aim is to develop the PVTTESTSYSTEM software to estimate PVT conditions when there are no laboratory tests. The study methodology is based on (i) Compilation of 10 PVT laboratory tests of oil wells in the eastern basin of Ecuador; (ii) Analysis of mathematical correlations; (iii) Development of the PVTTESTSYSTEM software, with the wells' initial conditions' input, selecting the mathematical correlation and estimation of results, based on the relationship of the properties of oil and gas; iv) Comparison of data obtained by laboratory tests and PVTTESTSYSTEM software reports. The software used with a graphical interface presents a registration and login platform and five modules that allow: inserting company and field data, initial oil well data, selecting correlations, calculating PVT properties and generating a graphic report. The results show that the mathematical correlations that estimate PVT properties were systematised, which approximate the laboratory tests' real results. The approximation of the calculated results with the actual results establishes a high confidence level for the PVTTESTSYSTEM software.

“…In almost all reservoirs, knowledge about condensate's PVT properties is a prerequisite to designing reservoir, production, and surface facilities. 10 PVT data can reflect the phase change of fluids, which is essential for modeling and simulating the production and development of hydrocarbon reservoirs. Both in conventional and unconventional resources, it plays a crucial role in the accuracy of many petroleum engineering calculations, such as material balance, reserve estimation, production data analysis, surface network modeling, and reservoir numerical simulation.…”

“…Both in conventional and unconventional resources, it plays a crucial role in the accuracy of many petroleum engineering calculations, such as material balance, reserve estimation, production data analysis, surface network modeling, and reservoir numerical simulation. 10 Unlike conventional oil and gas resources, in shale reservoirs, the number of organic, intergranular, and intragranular pores, which provide more space for accumulating hydrocarbon, is developed. Moreover, experiments such as high-pressure mercury intrusion and low-pressure adsorption have proven that these pores are mostly nanopores, 11,12 which restrict the flow of fluids.…”

“…Salahshoor et al 28 reviewed the impact of confinement on hydrocarbon phase behavior, mainly focusing on experimental and modeling outcomes, with little discussion on methods. El-Banbi et al 10 examined the selection of PVT correlations on geographical location, fluid type, required PVT model, data range and ranking, and expert system or set of rules. Moreover, they proposed a selection criterion for different PVT correlations.…”

Shale oil has received increasing attention as an essential replacement for conventional oil resources. Shale oil recovery is a complex process controlled by interactions of many factors whose impact could be significantly different from conventional reservoirs. This study hence aims to fill the gaps in the literature by studying various aspects of the phase behavior of shale oil and their significance in different aspects of the recovery from oil shale. In the first part of this study, the standard practices, including experimental and theoretical methods for calculating the pressure, volume, temperature (PVT), and phase behavior of shale oil, is discussed in detail. Next, the effects of factors such as the composition of fluids, pore structure, and capillary forces on the phase behavior of hydrocarbon fluids are explained. The third part focuses on applying phase behavior for oil shale development. Moreover, the geological and geochemical processes that lead to the maturity of kerogen, the formation of shale oil, and the experimental methods by which those processes are currently studied are scrutinized. By studying the thermal and burial history of the hydrocarbon-generating strata and hydrocarbon-generating kinetics, the shale formation's oil and gas phase distribution can be predicted. Consequently, the sweet spots for the recovery of light condensate oil can be more accurately determined. The application of enhanced oil recovery methods is an inevitable part of recovery from conventional and unconventional formations. Therefore, the last part of this study analyses the changes in the phase behavior of shale oil when an external component, i.e., CO 2 or CH 4 , is injected into the reservoir. Reviewing the literature revealed that a more accurate prediction of hydrocarbon phase behavior can be made by combining different disciplines of science to achieve optimized plans for efficient shale oil development, making shale oil a more economically viable energy resource.
