Available in PDF, EPUB and Kindle. Book excerpt: With vast potential reserves of heavy oil, the research on heavy oil has been the hottest topic over the decades. Foamy oil flow occurs in primary production of heavy oil reservoirs with unexpected high oil recovery factor. Studying on foamy oil mechanisms and flow behaviors helps enhancing oil recovery. Lots of experimental researches have been conducted to investigate on improving foamy oil flow efficiency. Pressure depletion rate has been proven to be one of the most significant parameters that affects foamy oil flow. However, the other factors that influence foamy oil such as reservoir temperature, oil viscosity, oil composition, etc. are not fully understood. Therefore, it is of great importance to study the influence of temperatures and oil viscosity on foamy oil flow. In this study, two types of experiment are carried out: (1) the sand-pack pressure depletion test under different temperatures; (2) sand-pack pressure depletion test with different viscous oils. In the first series of experiment, four different temperatures (20°C, 30°C, 40°C, 50°C) are selected to exam the production performance. In the second set of experiment, three heavy oil specimens with different oil viscosities are utilized under the same temperature condition (40°C). Initial gas oil ratio (GOR) is settled the same in all experiments. The experimental results of different temperatures indicate that foamy oil flow is weakened, and oil recovery factor declines with elevating temperatures. However, gas recovery factor increases when temperature rises. It is observed that the higher initial reservoir pressure does not certainly increase oil recovery factor during foamy oil flow. Given a favorable live oil viscosity, oil recovery can reach the optimized value. A new foamy oil behavior is discovered during the study, in which a second foamy oil flow appears during the late-time production. The experimental results of different viscosities showed that, there is an optimal live oil viscosity for foamy oil production because the results give a non-linear relationship between oil recovery factor and oil viscosity. The dead oil viscosity should also be considered when estimating oil recovery performance since oil viscosity is approaching to dead oil viscosity due to the relatively low reservoir GOR after gas is produced.

Book excerpt: The rheological studies of gas-oil dispersion are essential for understanding the foamy oil flow behaviours related to high production rates in many heavy oil reservoirs. The viscosity of gas-oil dispersion is one of the critical parameters that influence the recovery in solution gas drive process. Only a few laboratory experimental studies have been carried out to investigate the effects of live oil viscosity and foam quality on the apparent viscosity of the foamy oil during the depressurization process. As for gas-in-oil dispersion, the continuous phase is the supersaturated live oil during the depressurization process. It is essential to quantify the in-situ foam quality to verify the viscosity models for the foamy oil viscosity calculation under pressure conditions. However, none of those previous experimental studies has directly measured the in-situ foam quality, to the best of our knowledge. Hopefully, this study developed a novel visualization-based experimental method to measure the in-situ foam quality under reservoir conditions in both CO2-heavy oil system and methane-heavy oil system. The foam quality under non-equilibrium conditions was first measured and analyzed by a real-time visualization chamber system. Besides, the viscosity models for the foamy oil viscosity calculation have been generated in both CO2-heavy oil system and methane-heavy oil system. The viscosity correlations developed in this study are capable of predicting the in-situ viscosity of gas-oil dispersion in the solution gas drive process on both laboratory and field scales.

This book was released on 1990 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: A viscous pump design is developed and investigated which is more efficient than a viscous pump previously introduced (Etsion and Yaier, 1988). The key to the new design is straight lobes (V-lobes) as opposed to the semicircular lobes of the previous design. The straight lobe analysis, unlike the semicircular lobe analysis, does not produce a closed form solution. Approximations are made that are verified using shape factors and finite element models. Based on the analyses, the lobe geometry for each lobe design is optimized to produce maximum pumping capacity. The results of the analyses and optimizations, which are based on ideal boundary conditions, show that the straight lobe pump is theoretically superior to the semicircular lobe pump. A test rig was devised to test the semicircular lobe and the V-lobe design using a real time data acquisition system. The results of the experiments prove that the V-lobe is superior to the semicircular lobe. The experimental results showed good agreement with the analytical predictions, though some deviations were experienced at relatively low flow rates and high pressures. The deviations were attributed to the fact that the test pump did not have the ideal boundary conditions on which the analysis and optimization were based. Alternate boundary conditions were investigated using finite element models which better described the boundary conditions in the test pump. The analysis based on the new boundary conditions more appropriate to the test pump show excellent agreement with the experimental results.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viscoelastic fluids have recently received a significant amount of attention as potentially effective enhanced oil recovery (EOR) agents because of their viscoelastic properties in the pore space. However, the fundamental mechanisms by which they mobilize oil in porous media are still unclear. The objective of this work is to compare the efficacy of various viscoelastic fluids in enhancing oil recovery and improve the understanding of the displacement mechanisms governing oil recovery and pore-scale experimental approaches. First, the oil recovery efficiencies of viscoelastic surfactant (VES) solutions with different viscoelasticity in water-wet carbonate core samples were compared, confirming the key factors affecting the high recovery of the VES flooding are low interfacial tension (IFT), higher viscosity, and viscoelasticity. Viscoelasticity contributed to the oil recovery through the pulling effect and fragmenting of large oil globs into small ones. However, VES showed poor thermal stability and a significant reduction in viscosity and viscoelasticity at elevated temperatures. To overcome these limitations and expand the applications of VES, the impact of SiO2 nanoparticles (NPs) on the performance of VES flooding was investigated. The results suggest that the viscosity and viscoelasticity of the VES solution and the oil recovery were significantly improved by the addition of SiO2 NPs. In addition, oil clusters with non-spherical shapes were observed during NP-assisted viscoelastic surfactant (NVES) flooding because of high viscosity, viscoelasticity of the heavy oil and NVES solution, and NP jamming effect. Besides improving the viscoelastic properties of VES solutions, the potential use of NPs for in-situ upgrading of heavy oil and their effect on polymer flooding was also studied. The results indicated that the sequence of heavy oil upgrading in oil-saturated pore elements was governed by the relative magnitude of entry capillary pressure and followed a pore-size-based sequence, small pores first and large pores later. The addition of NPs boosted the oil recovery by polymer flooding with predominant contributions from the small pores under the capillary-dominated flow regime, and large pores for the viscous-dominated flow. Finally, under the oil-wet condition, the displacement mechanisms of polymer and surfactant-polymer (SP) flooding were also investigated. The results illustrate that the viscoelasticity contributed to the oil recovery by pulling the oil from dead ends and peeling oil from pore surfaces. Compared to polymer flooding, the displacement and sweep efficiencies were further enhanced by the SP flooding because of the reduced capillary forces due to the low IFT value, and the Jamin effect caused by the formation of an emulsion. The findings of this work provide new and unique pore-scale insights into the displacement mechanisms and efficiencies of different viscoelastic fluids, which can facilitate the design and optimization of chemical agents and formulations for enhancing the oil recovery from both light and heavy oil reservoirs.
