Available in PDF, EPUB and Kindle. Book excerpt: This RiMG (Reviews in Mineralogy & Geochemistry) volume includes contributions that review experimental, characterization, and modeling advances in our understanding of pore-scale geochemical processes. The volume had its origins in a special theme session at the 2015 Goldschmidt Conference in Prague. From a diversity of pore-scale topics that ranged from multi-scale characterization to modeling, this work summarizes the state-of-the-science in this subject. Topics include: modification of thermodynamics and kinetics in small pores. chemo-mechanical processes and how they affect porosity evolution in geological media. small angle neutron scattering (SANS) techniques. how isotopic gradients across fluid–mineral boundaries can develop and how these provide insight into pore-scale processes. Information on an important class of models referred to as "pore network" and much more. The material in this book is accessible for graduate students, researchers, and professionals in the earth, material, environmental, hydrological, and biological sciences. The pore scale is readily recognizable to geochemists, and yet in the past it has not received a great deal of attention as a distinct scale or environment that is associated with its own set of questions and challenges. Is the pore scale merely an environment in which smaller scale (molecular) processes aggregate, or are there emergent phenomena unique to this scale? Is it simply a finer-grained version of the "continuum" scale that is addressed in larger-scale models and interpretations? The scale is important because it accounts for the pore architecture within which such diverse processes as multi-mineral reaction networks, microbial community interaction, and transport play out, giving rise to new geochemical behavior that might not be understood or predicted by considering smaller or larger scales alone.

Download or read book Microfluidic Study of Calcium Carbonate Dissolution and Precipitation in Confinement written by Jianping Xu (Ph. D.) and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcium carbonate is the major carbon sink in the Earth system and its dissolution and precipitation are essential for carbon cycling between the geosphere, hydrosphere, and atmosphere. Given that the Earth is a rocky planet populated with life, often these dissolution and precipitation processes occur not in open waters, but in small confinement of rock and soil pores and cellular spaces in organisms. Examples include Karst dissolution and formation, rock weathering, soil carbonation, biomineralization, geologic carbon storage and petroleum reservoir acidizing. Fundamental understanding and control of dissolution and precipitation in confinement are still challenging due to the high complexity generated from multi-coupling between fluid transport, interfacial interactions, chemical reactions, and mineral phase transition. In this work, we fabricate glass microfluidic chips that house rock micropore-like confinements for the lab-on-a-chip investigations of calcium carbonate dissolution and precipitation. Optical transparency of the chips allows direct visualizations of pore-scale dynamic behaviors with high temporal and spatial resolutions, which is crucial for quantitative characterizations. First, through extensive experiments we discovered a series of novel regimes, patterns and mechanisms of calcium carbonate dissolution and precipitation confined in micrometer geometries. Previously unknown behaviors such as CO2 bubble breathing during carbonate dissolution, power-law particle size distribution of calcium carbonate precipitates, and the hydrodynamic instability induced by mineral phase transition are observed and quantified. Numerical and theoretical modeling are implemented to interpret the experimental results and demonstrate that small spatial confinement is actively shaping the mineral dissolution and precipitation dynamics. Second, novel experimental methodologies are developed to grow calcium carbonate in a glass microfluidic confinement either as scattered crystal particles or carbonate porous media. Utilizing the in situ grown carbonate porous media, we for the first time realize all the five classical carbonate rock dissolution regimes in a microfluidic chip. Extensive experiments are conducted to examine the effects of porous media heterogeneity and nonaqueous phases of oil and CO2 on the carbonate dissolution dynamics. Third, high-resolution microfluidic visualizations provide an analytical basis for tracking mineral surfaces and precise measurements of dissolution and precipitation rates. Therefore, the microfluidic approach can be utilized as a screening tool for faster carbonate mineralization, which is important for geologic carbon storage and other decarbonization technologies such as enhanced rock weathering and soil carbonation

Download or read book Reactive Transport in Natural and Engineered Systems written by Jennifer Druhan and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-03-04 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open system behavior is predicated on a fundamental relationship between the timescale over which mass is transported and the timescale over which it is chemically transformed. This relationship describes the basis for the multidisciplinary field of reactive transport (RT). In the 20 years since publication of Review in Mineralogy and Geochemistry volume 34: Reactive Transport in Porous Media, RT principles have expanded beyond early applications largely based in contaminant hydrology to become broadly utilized throughout the Earth Sciences. RT is now employed to address a wide variety of natural and engineered systems across diverse spatial and temporal scales, in tandem with advances in computational capability, quantitative imaging and reactive interface characterization techniques. The present volume reviews the diversity of reactive transport applications developed over the past 20 years, ranging from the understanding of basic processes at the nano- to micrometer scale to the prediction of Earth global cycling processes at the watershed scale. Key areas of RT development are highlighted to continue advancing our capabilities to predict mass and energy transfer in natural and engineered systems.

Download or read book Multiscale Pore Network Modeling of Carbonate Acidization written by Joseph Frederic Tansey and published by . This book was released on 2016 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Matrix acidization is important in many applications, particularly near-wellbore stimulation in carbonate reservoirs. Ideally, injected acid creates an array of highly conductive channels that greatly enhance permeability. A pore network model of matrix acidization is developed to predict this optimal injection rate, using novel representations of pore-scale physics in the form of a mass transfer coefficient and pore-merging criterion. Results are presented for both computer generated sphere packs and networks extracted from CT scans of carbonates. Simulations return an optimal Damköhler number close to experimental optimums, but predict significantly higher pore volumes to breakthrough than most experiments. This is posited to be due to the small domain size of network models.Mortar coupling is employed as a domain decomposition technique, and is verified to accurately capture the unique physics of matrix acidization. Many networks are coupled together to extend the simulated domain size in a parallel computing environment. A hybrid modeling technique is used to simplify large-scale simulations with the inclusion of Darcy-scale grid blocks in nonreactive regions. This is shown to preserve a high degree of simulation accuracy while improving computation time substantially. A two-scale continuum model is developed for integration with the hybrid technique. A pore network model is used to develop and upscale mass transfer coefficients, porosity-permeability relationship, and other structure-property relations. The resultant two-scale continuum model is shown to preserve a high degree of accuracy at high injection rates, but falls short of capturing intermediate dissolution regimes due to insufficient description of pore-scale species channeling. Simulations on larger domain sizes show reduced pore volumes to breakthrough. Radial domains are also investigated and show the characteristic dissolution regimes, lending support to common field-scale acidizing practice. Two-scale continuum models are concluded to be accurate representations of pore scale physics that can be used efficiently at larger scales. However, pore-scale modeling is still necessary to calibrate input parameters for the two-scale continuum model without resorting to destructive acidization experiments.
Download or read book Biomineralization written by Patricia M. Dove and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 54 of Reviews in Mineralogy and Geochemistry focuses upon the various processes by which organisms direct the formation of minerals. Our framework of examining biominerals from the viewpoints of major mineralization strategies distinguishes this volume from most previous reviews. The review begins by introducing the reader to over-arching principles that are needed to investigate biomineralization phenomena and shows the current state of knowledge regarding the major approaches to mineralization that organisms have developed over the course of Earth history. By exploring the complexities that underlie the "synthesis" of biogenic materials, and therefore the basis for how compositions and structures of biominerals are mediated (or not), we believe this volume will be instrumental in propelling studies of biomineralization to a new level of research questions that are grounded in an understanding of the underlying biological phenomena.
Download or read book Carbonate Reservoir Characterization A Geologic Engineering Analysis Part I written by G.C. Dominguez and published by Elsevier. This book was released on 1992-01-17 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book integrates those critical geologic aspects of reservoir formation and occurrence with engineering aspects of reservoirs, and presents a comprehensive treatment of the geometry, porosity and permeability evolution, and producing characteristics of carbonate reservoirs. The three major themes discussed are: • the geometry of carbonate reservoirs and relationship to original depositional facies distributions • the origin and types of porosity and permeability systems in carbonate reservoirs and their relationship to post-depositional diagenesis • the relationship between depositional and diagenetic facies and producing characteristics of carbonate reservoirs, and the synergistic geologic-engineering approach to the exploitation of carbonate reservoirs. The intention of the volume is to fully aquaint professional petroleum geologists and engineers with an integrated geologic and engineering approach to the subject. As such, it presents a unique critical appraisal of the complex parameters that affect the recovery of hydrocarbon resources from carbonate rocks. The book may also be used as a text in petroleum geology and engineering courses at the advanced undergraduate and graduate levels.
