Download or read book Investigation of Oil Recovery Improvement by Coupling an Interfacial Tension Agent and a Mobility Control Agent in Light Oil Reservoirs Summary Annual Report October 1994 September 1995 written by and published by . This book was released on 1995 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study will investigate two major areas concerning co-injecting an interfacial tension reduction agent(s) and a mobility control agent into petroleum reservoirs. The first will consist of defining the mechanisms of interaction of an alkaline agent, a surfactant, and a polymer on a fluid-fluid and a fluid-rock basis. The second is the improvement of the economics of the combined technology. The third year of the study finished the oil recovery coreflood studies and evaluated different techniques to improve alkaline-surfactant-polymer solution economics. The final series of corefloods compared the oil recovery efficiency of the alkali gradient in Berea sandstone and J Sand sandstone. Oil recovery efficiency was essentially the same in both types of core, 13 to 15% PV of oil. Cost of chemical per incremental barrel of oil with 30% pore volume of alkaline-surfactant- polymer solution injected were $3.20 for the Na2CO3- Petrostep B-100-Flopaam 3330S solution in both types of core.

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.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book A Study of Microemulsion Viscosity with Consideration of Polymer and Co solvent Additives written by Ghazal Dashti and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the dramatic increase in the worldwide demand for the crude oil and with the fact that the oil and gas resources are depleting, the enhanced oil recovery process plays an important role to increase the production from the existing hydrocarbon reservoirs. Chemical enhanced oil recovery is one of the most important techniques to unlock significant amount of trapped oil from oil reservoirs. Surface agent materials (Surfactants) are used to lower the interfacial tension (IFT) between water and oil phases to ultralow values and mobilize the trapped oil. When surfactant, water, and oil are mixed together they form a thermodynamically stable phase called microemulsion which can be characterized by ultralow interfacial tension and the ability to solubilize both aqueous and oil compounds. Another characteristic of microemulsion solution is its viscosity which plays an important role in the creation and movement of the oil bank. The microemulsion micro-structure is complex and its viscosity is difficult to predict. Various viscosity models and correlations are presented in the literature to describe microemulsion viscosity behavior, but they fail to represent the rheological behavior of many microemulsion mixtures. Most of these models are valid in the lower and higher ranges of solute where one of the domains is discontinuous. The majority of the models fail to calculate the rheology of microemulsion phase in bicontinuous domains. In this work, we present a systematic study of the rheological behavior of microemulsion systems and the effect of additives such as polymer and co-solvent on rheological properties of microemulsions. Several laboratory experiments were conducted to determine the rheological behavior of surfactant solutions. A new empirical model for the viscosity of microemulsion phase as a function of salinity is introduced. The model consists of three different correlations one for each phase type of Windsor phase behaviors. The proposed model is validated using a number of experimental results presented in this document. The proposed viscosity model is implemented in the UTCHEM simulator and the simulator results are compared with the coreflood experiments. Excellent matches were obtained for the pressure. We further improved the proposed viscosity model to incorporate the effect of polymer and co-solvent on the microemulsion viscosity.
