This book was released on 2016-05-14 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the current application of nanotechnology in oil and gas industries and explores new research directions in this frontier field. It outlines the theory and practical challenges of the nanoparticle colloidal behavior in oil matrixes and aqueous solutions, the interactions between rock and nanofluid, and the surface phenomena relevant to the application of this technology. The book also describes the transport behavior of nanoparticles in oil/sand media for in-situ upgrading and recovery of heavy oil. Currently, the main objectives of applying nanoscale materials in oil and gas industries are the remediation of formation damage, the improvement of energy efficiency, the abatement of environmental footprints and the increment of recovery factors of oil reservoirs, to name a few. The book consists of six chapters with contributions by leading experts in the topics of fabrication methods, opportunities and challenges in the oil & gas industry, modeling and application of nanofluids in the field and environmental applications of nanoparticles. The growing demand for oil has led to the need to exploit unconventional oil resources, such as heavy and extra-heavy crude oil. However, in the current context, upgrading and recovery of heavy oil are highly energy and water intensive, which consequently results in environmental impacts. Therefore, it is necessary to search for new ideas and alternatives in the field of in-situ and ex-situ upgrading and recovery to improve current technologies and make them both environmentally sound and cost-effective. Research conducted by the authors and numerous other researchers has shown that nanoparticle technology could be successfully employed for enhancing the upgrading and recovery of heavy oil with cost-effective and environmentally friendly approaches. Examples on the applications of nanoparticles in heavy oil include the adsorption, oxidation, and gasification/cracking of asphaltenes, a problematic constituent present in heavy oils; in-situ upgrading of the Athabasca bitumen by multi-metallic in-situ prepared nanocatalysts; the inhibition of precipitation and deposition; and the enhanced perdurability against asphaltene damage in oil sands porous media by injection of nanofluids; sequestration of oil from spilled emulsions by nanoparticle supported alumina etc.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable world economy requires a steady supply of crude oil without any production constraints. Thus, the ever-increasing energy demand of the entire world can be mostly met through the enhanced production from crude oil from existing reservoirs. With the fact that newer reservoirs with large quantities of crude oil could not be explored at a faster pace, it will be inevitable to produce the crude oil from matured reservoirs at an affordable cost. Among alternate technologies, the chemical enhanced oil recovery (EOR) technique has promising potential to recover residual oil from matured reservoirs being subjected to primary and secondary water flooding operations. Due to pertinent complex phenomena that often have a combinatorial role and influence, the implementation of chemical EOR schemes such as alkali/surfactant/polymer flooding and their combinations necessitates upon a fundamental understanding of the potential mechanisms and their influences upon one another and desired response variables. Addressing these issues, the book attempts to provide useful screening criteria, guidelines, and rules of thumb for the identification of process parametric sets (including reservoir characteristics) and response characteristics (such as IFT, adsorption etc.,) that favor alternate chemical EOR systems. Finally, the book highlights the relevance of nanofluid/nanoparticle for conventional and unconventional reservoirs and serves as a needful resource to understand the emerging oil recovery technology. Overall, the volume will be of greater relevance for practicing engineers and consultants that wish to accelerate on field applications of chemical and nano-fluid EOR systems. Further, to those budding engineers that wish to improvise upon their technical know-how, the book will serve as a much-needed repository.

Download or read book Formation Damage in Oil and Gas Reservoirs Nanotechnology Applications for Its Inhibition Remediation written by Camilo Andrés Franco Ariza and published by Nova Science Publishers. This book was released on 2018-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of conventional and unconventional hydrocarbons can be affected by several sources of damage under subsurface conditions that can hinder well productivity. Damage may occur during different stages of oil and/or gas well formation such as production, drilling, hydraulic fracturing, and workover operations.For years, formation damage was considered negligible or was not treated adequately, causing reductions in the production rate up to the loss of both producer and injector wells. Nowadays, formation damage is an essential parameter to be considered in the wells' development as its prevention and/or engineered remediation may lead to cost reduction and improvement of production rate. Formation damage is challenging in the oil and gas industry, as it implies a large number of mechanisms that can be involved. Different fields feature problems associated with fines migration, asphaltene precipitation/deposition, inorganic scales, condensate banking, and damage during hydraulic fracturing operations, among others.Nanotechnology is a rapidly growing technology with potential applications and benefits. Among the numerous applications of nanotechnology for energy and the environment, the nanoparticle technology could be successfully employed as an attractive alternative in the oil and gas industry for the inhibition and remediation of different types of formation damage with cost-effective and environmentally friendly approaches. Due to their exceptional physicochemical properties such as high dispersibility, high surface area/volume ratio and small size (1-100 nm), nanoparticles are able to inject into the reservoir, travel smoothly through the porous media and selectively attack a specific type of formation damage. Also, at the nanoscale, other exceptional properties can be obtained, such as high thermal stability and chemical stability, as well as optically, magnetically, and electrically tunable properties.This book provides recent research on nanotechnology applied to the inhibition/remediation of formation damage in oil and gas reservoirs. The chapters include methodologies for multi-component skin characterization, estimating the level of risk of formation damage, nanoparticle fabrication methods, as well as the application of nanoparticles and nanofluids at both laboratory and field conditions. This book should generate a better landscape about the use of nanoparticles and nanofluids in the improvement of inhibition and treatment of formation damage, and its application in local and international scenarios.

Download or read book Ferrofluid Applications in Petroleum Engineering written by Ningyu Wang (Ph. D. in petroleum engineering) and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferrofluid is a stable suspension of superparamagnetic nanoparticles (SMNPs). Because of their small size, and with suitable coating, SMNPs stay suspended in the fluid and their retention in porous media is minimized. When exposed to an external magnetic field, the SMNPs align with the magnetic field, triggering magnetic, mechanical, and thermal phenomena. When the external magnetic field is removed, the orientation of the SMNPs restores randomness. In this study, we explored two applications of ferrofluid in petroleum engineering. First, we explored the potential of SMNPs for flow assurance, more specifically, de-waxing. Exposing SMNPs to an alternating magnetic field produces heating due to Neel's relaxation. SMNPs can be dispersed, lodged within a coat of paint, and applied to a pipe's interior (nanopaint). The heating effect of nanopaint in a pipe was initially explored and the idea of injecting an electromagnetic source into pipeline for dewaxing purposes was proposed by Mehta et al. in 2015. However, they performed fewer than 10 simulations and did not consider pig movement or flowing hydrocarbon. In this study, three numerical models were set up to study the heating process of an electromagnetic dewaxing system in a pipeline with wax deposition. The device that emits the alternating magnetic field is named an electromagnetic pig, and the corresponding dewaxing process is called electromagnetic pigging. Induction heat is generated in the nanopaint layer in the pipeline and is transported to the deposited wax to melt at least part of the wax to dissolve the wax back into the flowing hydrocarbon or to peel the wax off the pipeline wall. The heating effectiveness and efficiency of a simplified electromagnetic pig composed of a single solenoid coil were numerically studied in the commercial multiphysics simulation software COMSOL. Heating effectiveness was evaluated by heating zone length, heating zone depth, and maximum pig speed, while heating efficiency was evaluated by pig induction factor (PIF). Simulation results show that the solenoid coil should have a longer radius and shorter length to achieve better wax-heating performance. Shorter coil length slightly increases the heating effectiveness and heating efficiency. Longer coil radius increases the heating effectiveness and yields stable heating efficiency. The impact of coil radius on heating efficiency is complicated, while longer coil radius avoids the lowest-efficiency region. The pig speed should be faster to decrease operation time and increase heat efficiency, as long as the heating effectiveness does not drop too much and the wax can still melt and peel off. A battery of100 kW h can power the pig to melt 216 kg of deposited wax and peel off several times more wax, which is sufficient to dewax a 0.2-m inner radius pipeline of 1.78 km (1.1 mi). To melt a longer section of pipeline, a larger battery set or a fleet of pigs would be necessary. Although the system is designed to lower the hydrocarbon temperature in the pipeline, higher hydrocarbon temperature helps the electromagnetic dewaxing. Second, we explored ferrofluid-fluid displacement at the pore scale with the potential to enhance oil recovery using microfluidic experiments. Nanoparticles have great potential to mobilize trapped oil in reservoirs by reducing the oil-water interfacial tension, altering the rock wettability, stabilizing foams and emulsions, and heating the reservoir to decrease the oil viscosity. However, the direct application of magnetic forces on SMNPs in reservoir engineering applications has not been extensively investigated. Possible oil recovery by magnetic forces when the magnetic field is parallel to the flow direction was predicted by Soares in 2014, but no experiment results have confirmed the oil recovery or the mechanism. In this study, we demonstrate the enhanced oil recovery (EOR) potential of hydrophilic magnetic nanoparticles in oil production by direct observation using microfluidics, and we examine the mechanism and hypothesize new theories to explain the experimental phenomena. Ferrofluid flooding experiments were performed in a micromodel of a converging-diverging single channel and then in a micromodel of a foot-long pore network, both with varying depth (so-called 2.5D micromodel). The micromodels were made of glass, and thus, the water-based ferrofluid was the wetting fluid. Initial ferrofluid flooding experiments in single channels were performed under a static magnetic field transverse to the flow direction. This magnetic field caused oil droplet deformation, dynamic break-up into smaller droplets, and subsequent residual oil saturation reduction. Significant oil blob displacement was observed within 2 hours after the magnetic field was applied. During one flooding experiment, the oil saturation within the observation area of the micromodel reduced from 27.4% to 12.0%. This result contrasts with the prediction of the theory of magnetic forces, and we hypothesize that oil recovery is at least partly attributed to the temporary SMNP microstructures in the ferrofluid when exposed to an external magnetic field. We then designed a rotating magnetic device to examine the hypotheses and to reveal that a changing field would have an even larger effect on saturation reduction. We subsequently observed a completely different phenomenon, namely self-assembly of oil droplets, indicating the formation of hydrophilic SMNP microstructures (chains under the magnetic field). These SMNP microstructures were ever-changing under the rotating external magnetic field. While the ability of ferrofluid to rotate small blobs was interesting in and of itself, in experiments without actual flooding (and thus synergy of hydrodynamic and magnetic forces), we did not observe any additional oil recovery. Further ferrofluid flooding experiments were performed in a foot-long 2.5D micro-model in a rotating external magnetic field to study the oil recovery effect of the rotating magnetic field at the core scale. In one experiment, the oil saturation dropped from 44.6% to 33.3% after the rotating magnetic field was applied. The additional oil recovery of 11.3% shows good potential for ferrofluid flooding with a rotating external magnetic field
