Book excerpt: Over the last two decades, earth modeling has become a major investigative tool for evaluating the potential of hydrocarbon reservoirs. Earth modelling must now face new challenges since petroleum exploration no longer consists in only investigating newly identified resources, but also in re-evaluating the potential of previously investigated reservoirs in the light of new prospecting data and of revised interpretations. Earth models incorporate a variety of different interpretations made on various types of data at successive steps of the modeling process. However, current modeling procedures provide no way to link a range of data and interpretations with a final earth model. For this reason, sharing and exchanging information about the model building process is at present a major difficulty. Recently, the term “Shared Earth Modeling” has been used for expressing the idea that earth models should be built in such a way that experts and end users can have access, at any time, to all the information incorporated into the model. This information does not only concern the data, but also the knowledge that geoscientists produce by interpreting these data. Accordingly, practical solutions must be studied for operating a knowledge-driven approach of Shared Earth Modeling. This is the goal of this book. This study of earth subsurface modeling is intended for several categories of readers. It concerns in the first place geologists, engineers and managers involved in the study and evaluation of subsurface reservoirs and hydrocarbon exploration. Relying on recent progress in various fields of computer sciences, the authors present innovative solutions for solving the critical issue of knowledge exchange at key steps of the modeling process. This book will also be of interest to researchers in computer science and, more generally, to engineers, researchers and students who wish to apply advanced knowledge-based techniques to complex engineering problems.

Download or read book A Demonstration of Geologic and Geophysical Modeling with Legacy Seismic and Well Data written by Kimberley Harr and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to construct a geologic and geophysical model of the Hunter modeling domain on the western slope of the San Rafael Swell near Castle Dale, Utah. The purpose of developing this model is to aid in CO2 migration simulations for carbon sequestration which has the potential to offset greenhouse gases and aid in the fight against global warming. The model is intended to help understand the lateral and vertical migration potential of a CO2 plume by understanding formation structures such as dip angle and faulting. The geophysical model aided building the geologic structure model by providing inter-well control of formation horizons. This study investigates the geologic and geophysical properties of the modeling domain with the use of well tops, well log data, outcrop points, 2D seismic profiles and velocity stacking data.This research resulted in a 30 square mile (48 km2) geologic model characterized by conformable geologic formations that dip southwesterly ~2.4° and thicken to the southwest.

Book excerpt: GEOPHYSICAL APPROACHES IN GEOLOGICAL STRUCTURE ASSESSMENT This book illustrates how geophysical methods can be used in subsurface investigations and exposed outcrops. It was written to share the knowledge of geophysical approaches (2-D resistivity, seismic refraction and ground magnetic) applied in making assessments towards geological structures. Furthermore, it presents, in detail, the importance of these methods in delineating the subsurface features with the purpose of enhancing the comprehension regarding the knowledge and concepts of the geophysical methods. This book accordingly compiles several case studies to capture the readers' interests and to ease their understanding. The geophysical methods used are non-destructive, rapid, relatively economic, and can vastly improve the characterization of the subsurface features. The correlation with geological parameters is used to validate the geophysical results for improved interpretations and analyses. The authors foreseen that this book has the potential to better expand the knowledge and share the experiences with those from the same field or to someone new to it.

Download or read book 3 D Seismic Survey Design Via Modeling and Reverse Time Migration written by Suleyman Coskun and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic forward modeling studies are required for adequately imaging complex geological structures, such as folds, faults, and domes. Many U.S. Gulf Coast salt domes are used for oil and gas exploration, brine production, and underground hydrocarbon storage. For this reason, it is crucial to image the flank of the salt domes and surrounding sediments. Allied Geophysical Laboratories (AGL) carried out a 2-D seismic study in the Texas Brine Company facility to image the Pierce Junction salt dome. However, we were not able to image the salt flanks because of improper survey design. This led to the current study which proposes a 2-D and a 3-D seismic survey design using modeling and Reverse Time Migration (RTM) imaging. We gathered original 2-D seismic, topography, and gravity data to build 2-D and 3-D velocity models of the Pierce Junction salt dome area. We processed the original 2-D data and extracted the velocities of the cap rock and near surface sediments for use in velocity models. We modelled gravity data collected in a north-south direction and performed analyses on the synthetic seismic data to determine new 2-D conventional seismic survey parameters that could be achieved with the limited acquisition equipment of AGL. We modeled synthetic shot gathers by a finite difference method using the full (two-way) acoustic wave equation, and generated seismic images using the Reverse Time Migration (RTM) method. We determined the optimum parameters of the new 2-D seismic survey by reviewing the quality of the results. These parameters were able to adequately image the salt dome and its surrounding sediments. We then modified the 2-D parameters for a new 3-D survey, and obtained synthetic RTM images based on the 3-D velocity model. Optimal 2-D and 3-D seismic survey designs for the Pierce Junction salt dome area were achieved using seismic modeling and RTM imaging. We found RTM imaging to be a novel and powerful method for determining seismic survey parameters for complex geological structures.

Download or read book Seismic Reservoir Modeling written by Dario Grana and published by John Wiley & Sons. This book was released on 2021-05-04 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic reservoir characterization aims to build 3-dimensional models of rock and fluid properties, including elastic and petrophysical variables, to describe and monitor the state of the subsurface for hydrocarbon exploration and production and for CO2 sequestration. Rock physics modeling and seismic wave propagation theory provide a set of physical equations to predict the seismic response of subsurface rocks based on their elastic and petrophysical properties. However, the rock and fluid properties are generally unknown and surface geophysical measurements are often the only available data to constrain reservoir models far away from well control. Therefore, reservoir properties are generally estimated from geophysical data as a solution of an inverse problem, by combining rock physics and seismic models with inverse theory and geostatistical methods, in the context of the geological modeling of the subsurface. A probabilistic approach to the inverse problem provides the probability distribution of rock and fluid properties given the measured geophysical data and allows quantifying the uncertainty of the predicted results. The reservoir characterization problem includes both discrete properties, such as facies or rock types, and continuous properties, such as porosity, mineral volumes, fluid saturations, seismic velocities and density. Seismic Reservoir Modeling: Theory, Examples and Algorithms presents the main concepts and methods of seismic reservoir characterization. The book presents an overview of rock physics models that link the petrophysical properties to the elastic properties in porous rocks and a review of the most common geostatistical methods to interpolate and simulate multiple realizations of subsurface properties conditioned on a limited number of direct and indirect measurements based on spatial correlation models. The core of the book focuses on Bayesian inverse methods for the prediction of elastic petrophysical properties from seismic data using analytical and numerical statistical methods. The authors present basic and advanced methodologies of the current state of the art in seismic reservoir characterization and illustrate them through expository examples as well as real data applications to hydrocarbon reservoirs and CO2 sequestration studies.
Download or read book Industrial Structural Geology written by F.L. Richards and published by Geological Society of London. This book was released on 2015-10-22 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practical application of structural geology in industry is varied and diverse; it is relevant at all scales, from plate-wide screening of new exploration areas down to fluid-flow behaviour along individual fractures. From an industry perspective, good structural practice is essential since it feeds into the quantification and recovery of reserves and ultimately underpins commercial investment choices. Many of the fundamental structural principles and techniques used by industry can be traced back to the academic community, and this volume aims to provide insights into how structural theory translates into industry practice. Papers in this publication describe case studies and workflows that demonstrate applied structural geology, covering a spread of topics including trap definition, fault seal, fold-and-thrust belts, fractured reservoirs, fluid flow and geomechanics. Against a background of evolving ideas, new data types and advancing computational tools, the volume highlights the need for structural geologists to constantly re-evaluate the role they play in solving industrial challenges.
