Book excerpt: Development Theories and Methods of Fracture-Vug Carbonate Reservoirs explores the theories and methods for successful development of a fracture-vug reservoir by presenting the developmental strategies used in the Tahe oilfield. Some of the theories and methods of developing the Tahe fracture-vug reservoirs have been inspired by two China national research projects: The ‘Basic research on development of fracture-vug carbonate reservoirs’ (2006-2010), and the ‘Basic research on production mechanism and oil recovery enhancement of fracture-vugcarbonate reservoirs’ (2011-2015), with support by the National Basic Research Program of China. These theories and methods have facilitated the successful development of the fracture-vug reservoir in the Tahe oilfield, providing effective technologies and inspirations to developing similar reservoirs everywhere. Provides information on both theoretical developments and technological innovations Applies the modern karst formation characterization and the fracture-vug hierarchical structure to geological investigations of fracture-vug carbonate reservoirs Introduces the karst facies-controlling 3D geologic modeling of fracture-vug reservoir formations Proposes the coupled-processing and equivalent multi-medium numerical simulation methods of fracture-vug reservoirs Presents development methodologies and techniques of water/gas flooding

This book was released on 2020-08-27 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of naturally fractured reservoirs, especially shale gas and tight oil reservoirs, exploded in recent years due to advanced drilling and fracturing techniques. However, complex fracture geometries such as irregular fracture networks and non-planar fractures are often generated, especially in the presence of natural fractures. Accurate modelling of production from reservoirs with such geometries is challenging. Therefore, Embedded Discrete Fracture Modeling and Application in Reservoir Simulation demonstrates how production from reservoirs with complex fracture geometries can be modelled efficiently and effectively. This volume presents a conventional numerical model to handle simple and complex fractures using local grid refinement (LGR) and unstructured gridding. Moreover, it introduces an Embedded Discrete Fracture Model (EDFM) to efficiently deal with complex fractures by dividing the fractures into segments using matrix cell boundaries and creating non-neighboring connections (NNCs). A basic EDFM approach using Cartesian grids and advanced EDFM approach using Corner point and unstructured grids will be covered. Embedded Discrete Fracture Modeling and Application in Reservoir Simulation is an essential reference for anyone interested in performing reservoir simulation of conventional and unconventional fractured reservoirs. Highlights the current state-of-the-art in reservoir simulation of unconventional reservoirs Offers understanding of the impacts of key reservoir properties and complex fractures on well performance Provides case studies to show how to use the EDFM method for different needs

Book excerpt: This report covers Task 3, Immiscible gas-oil flow in fractured/layered porous media, Part 1, Viscous displacement in fractured porous media: Experiments and Analysis of experiments and Task 5, Simulation of fractured reservoirs, Dual-porosity simulation incorporating reinfiltration and capillary continuity concepts, Part 3, Interaction between grid cells. In some fractured reservoirs, a gas pressure gradient of the order of 0.1 psi/ft may be established in the fractures due to flow. Such a pressure gradient could result in recovery enhancement of the matrix oil. Several tests were conducted to study viscous displacement in fractured porous media. These tests included both gravity drainage with free gas displacement and forced gas displacement. The results show that there is considerable recovery improvement due to viscous displacement. Numerical results are in very good agreement with the experimental data. In Task 5, the authors propose a method which accounts for reinfiltration and capillary continuity not only within a grid cell, but also between various grid cells. A reinfiltration term is added to the dual-porosity model and the exchange term between the matrix and the fracture is calculated in a simple manner. Four example problems demonstrate the usefulness of the proposed method.

This book was released on 1996 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of experiments have been performed to study water injection in fractured porous media. These experiments reveal that: (1) the co-current imbibition may be the primary flow process in water-wet fractured media, and (2) the imbibition may result in over 20 percent recovery from very tight rock (Austin Chalk with K{sub ma} of the order of 0.01 md) for an imbibition period of about 2 months. Theoretical consideration reveal that the exponential function of Aronofsky et al. [''A Model for the Mechanism of Oil Recovery from Porous Matrix Due to Water Invasion In Fractured Reservoirs, '' Trans. AIME (1958) 213, 17-19] does not describe the early-time, but may represent the late-time recovery.

This book was released on 2021-08-05 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: As unconventional reservoir activity grows in demand, reservoir engineers relying on history matching are challenged with this time-consuming task in order to characterize hydraulic fracture and reservoir properties, which are expensive and difficult to obtain. Assisted History Matching for Unconventional Reservoirs delivers a critical tool for today’s engineers proposing an Assisted History Matching (AHM) workflow. The AHM workflow has benefits of quantifying uncertainty without bias or being trapped in any local minima and this reference helps the engineer integrate an efficient and non-intrusive model for fractures that work with any commercial simulator. Additional benefits include various applications of field case studies such as the Marcellus shale play and visuals on the advantages and disadvantages of alternative models. Rounding out with additional references for deeper learning, Assisted History Matching for Unconventional Reservoirs gives reservoir engineers a holistic view on how to model today’s fractures and unconventional reservoirs. Provides understanding on simulations for hydraulic fractures, natural fractures, and shale reservoirs using embedded discrete fracture model (EDFM) Reviews automatic and assisted history matching algorithms including visuals on advantages and limitations of each model Captures data on uncertainties of fractures and reservoir properties for better probabilistic production forecasting and well placement

Download or read book Well Test Analysis for Fractured Reservoir Evaluation written by G. Da Prat and published by Elsevier. This book was released on 1990-11-19 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this book is to provide the reader with a basic understanding of the behaviour of fractured reservoirs, using evaluation techniques based on processing pressure and flow-rate data resulting from production testing.It covers the fundamental reservoir engineering principles involved in the analysis of fluid flow through fractured reservoirs, the application of existing models to field cases, and the evaluation and description of reservoirs, based on processed data from pressure and production tests. The author also discusses production decline analysis, the understanding of which is a key factor influencing completion or abandonment of a well or even a field.The theoretical concepts are presented as clearly and simply as possible in order to aid comprehension. The book is thus suitable for training and educational purposes, and will help the reader who is unfamiliar with the subject acquire the necessary skills for successful interpretation and analysis of field data.One of the most important features of the book is that it fills the gap between field operations and research, in regard to proper management of reservoirs. The book also contains a computer program (FORTRAN language) which can be incorporated in existing software designed for reservoir evaluation; type curves generation, test design and interpretation, can be achieved by using this program.Petroleum engineers, reservoir engineers, petroleum geologists, research engineers and students in these fields, will be interested in this book as a reference source. It can also be used as a text book for training production and reservoir engineering professionals. It should be available in university and oil company libraries.

This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical gas saturation and solution gas drive performance of a heavy oil (?0 = 17,000 cp) in a Berea core sample was measured. The critical gas saturation is less than 1.5 percent. But, the solution gas drive process for the heavy oil, unlike the light oil, is very efficient. While reducing the system pressure from a bubble point pressure of 445 psia to a pressure of 330 psia, 11 percent of the oil was produced from the core. In view of the high recovery due to solution gas drive, a duplicate experiment is being conducted. The pressure will be lowered to near 50 psia in the duplicate experiment.

This book was released on 1997 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase flow in fractured porous media is a complex problem. While the study of single phase flow in a fractured or a layered medium can be pursued by some kind of averaging process, there is no meaning to averaging two-phase flow when capillarity is an active force. For a two-layer system comprised of high and low permeable layers, the performance of gas-oil gravity can be less efficient than the homogeneous low permeable medium. On the other hand, heterogeneity may enhance water imbibition due to capillarity. Due to the above and various other complexities, current tools for predicting the performance of fractured hydrocarbon reservoirs are not reliable. Based on the research work carried out at the Reservoir Engineering Research Institute, and some other Institutions, a good deal of progress has been made in recent years. But still we are a long way from good predictive reservoir models. In this final report, we summarize some of our achievements in the understanding of multiphase flow in fractured media. Since some of the features of two-phase flow in fractured and layered many are similar due to the capillary forces, the work includes progress in both types of media. There are some basic issues of flow in both fractured and unfractured media that are currently unresolved. These issues include: (1) new phase formation such as the formation of liquid phase in gas condensate reservoirs, and gas phase formation in solution gas drive process and (2) composition variation due to thermal convection and diffusion processes. In the following, a brief summary of our findings in the last three years during the course of the project is presented.

Book excerpt: We have developed a simple method to account for reinfiltration and capillary continuity processes in a grid cell that may contain a large number of matrix blocks. This method requires fine grid simulation of a three-block stack. The proposed technique also takes into account the variation of capillary pressure, and even permeability and height variation among various matrix blocks reasonably well.
