“…By using a wheel shaped flow loop (the wheel), which is a closed system, it was possible to achieve phase transition by adjusting the temperature only. Use of the wheel has previously been reported in the literature by several authors. − The results of the current work presented here indicated that, in general, the thermodynamic models were appropriate for the current system. Furthermore, the separation studies indicated that, for the design and operation of CO 2 –oil separation units and transport of CO 2 rich fluids, it is important to be able to predict which liquid phase is the continuous one and the separation time scale expected for a given fluid system under operating conditions.…”

Presented here is experimental and theoretical work on phase transitions and separation time scales for CO2–crude oil mixtures with CO2 content ranging from pure to 79 mol %. The experimental work was performed using the wheel flow loop located at the SINTEF Multiphase Flow Laboratory. Under constant volume conditions, phase transition temperature and pressures were determined, as well as the volume fractions of the respective phases. The results indicated good agreement between the experimentally determined phase transitions and the phase diagrams predicted by the thermodynamic model. It was shown that the measured torque was sufficient to determine the pressure–temperature conditions of the phase transitions. Furthermore, separation times were measured for both oil-in-CO2 and CO2-in-oil in a range of conditions for the respective fluid systems. Results showed that the separation times were considerably shorter for the CO2 continuous fluid system compared to oil continuous. Moreover, a comparison of Weber numbers for the various test conditions indicated that the drop sizes influence the overall separation time, which is affected by settling and coalescence processes. Finally, this study showed that the wheel flow loop is well suited for the study of CO2-rich systems for determination of volume fractions of phases, phase transitions, and transport and separation.

“…Generally, the coarser clastic reservoirs deposited or matured in a compressive stress regime show the development of deformation bends that can drastically reduce the lateral permeability of the reservoir (Zhang and Ertekin 2019). The tracer technique can help in delineating these zones and associated deformation zones (Agency 2004;Peralta Gomes et al 2018;Pérez-Romero et al 2020;Schümann and Fossen 2018;Wrona et al 2019). Objectives (qualitative and quantitative) of IWTT are described by (Sanni et al 2015) and are depicted in Fig.…”

The significance of the tracer testing technique is widely accepted in reservoir performance analysis in hydrology as well as in hydrocarbon exploration and production. The subsurface reservoir delineation for hydrocarbon exploration and optimum production is one of the most critical aspects of petroleum system analysis. The quality of the reservoir and its performance prediction require extensive knowledge of qualitative reservoir geology, its depositional environment, facies heterogeneity and engineering properties of subsurface formations. Tracer testing is amongst the few techniques available in the oil and gas (O&G) industry, which stands up to these expectations and is successfully used for quantitative determination and analysis of sub-seismic scale structural and stratigraphic heterogeneities. Tracer testing is also being utilized in determining residual oil saturation (Sor) and lateral correlation of reservoir properties in the subsurface. Apart from the O&G industry, the concentration-based applications of tracer testing have been proved in hydrology, geothermal and medical science. A comprehensive review is presented to explain the application of tracer testing technique to investigate porous media, mainly in O&G industry. The type of tracers used, their selection criteria, concentration, and natural versus gradient and qualitative to a quantitative application are discussed in the current review. Generally, two types of tracers (chemical and radioactive) are preferred in the petroleum industry for gas/fluid flow assessment, waterflood optimization and establishing connectivity between multiple wells. The current paper reviews both types of tracer tests, namely single well and inter well, in detail discussing the objectives, calculations, designing, injection, sampling, laboratory analysis and knowledge integration. The preliminary aim was to provide a review of the tracer testing technique used in reservoir evaluation and well-to-well connectivity analysis.

“…Because of substantial hydrogen and acid emissions in powerful fuel products, their transit in pipes is adversely impacted. Two-step oil and water source segregation is also common in the oil business, as seen by the final segregation stage in the wells [7]. Water from the pipeline may be combined with gas in a tank to boost the amount of oil produced.…”

In this study, computational analysis has been carried out using computational fluid dynamics (CFD). These calculations have been made to investigate the rheological behavior of the mixed-phase flow in horizontal pipelines. In order to study the shear stress in a vertical pipe, a new numerical model for oil-water dispersion in three dimensions has been developed. CFD software has been used to study the wall shear stress function and water droplet pressure. Using Reynolds numbers and the Navier-Stokes equations with k–turbulence factor to save energy, the flow range for the continuous process was explained. The results from a recent study on experimental methodology were simulated. In this study, the diameter of the tube is 40 mm and the length is 3.5 m and modeled and analyzed using Ansys software. Thus, the geometry has been imported and modeled using the CFD tool. The meshed model has been tested and converged accordingly. The primary data of the simulation have been verified with experimental results successfully. Oil droplet widths have previously been thought to be dependent on the flow Reynolds number, which was confirmed in this case study. Droplet diameter Dd was measured at 6 mm while the mixture moved at a speed of 1.9 m/s. It was found that the largest shear stress value was found at the top of the pipe, where the oil fraction (cut-off) was 0.3, in the simulation results for varied velocities (1.6, 2.5, 2.9 m/s) and oil fraction (cut-off) values. The results of the simulation analysis of the two-phase flow of crude oil for the horizontal pipe are wall shear stresses with different velocities for crude oil in the two-phase flow. As well as pressure drop at different velocities for the same fluids
