Download or read book Finite Conductivity Horizontal Well Fractures written by Mohammed Al-Kobaisi and published by LAP Lambert Academic Publishing. This book was released on 2010-09 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontal wells are preferred in the oil and gas fields because of their effectiveness in heterogeneous reservoirs, potential in enhanced oil recovery, ability to reduce coning, and advantages in environmentally sensitive areas. For tight formations, the productivity of a horizontal well can be further increased by hydraulic fracturing. Recently, interest in improved models and understanding of fractured horizontal wells has been elevated due to their success in exploiting unconventional reservoirs, such as shale gas. This book presents a research on the transient pressure responses and modeling of horizontal wells with transverse vertical fractures. A hybrid numerical-analytical model is developed where the fracture flow is numerically simulated and dynamically coupled with an analytical solution for the reservoir flow. The hybrid model reduces the computational work while providing for incorporating the details of the fracture flow and different fractured horizontal well geometries. The book is intended for researchers as well as the practicing engineers in the areas of petroleum production and reservoir engineering, well completions, and stimulations.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific understanding of fluid flow in rock fracturesâ€"a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storageâ€"has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
Download or read book Development of Unconventional Reservoirs written by Reza Rezaee and published by MDPI. This book was released on 2020-04-16 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for energy is increasing and but the production from conventional reservoirs is declining quickly. This requires an economically and technically feasible source of energy for the coming years. Among some alternative future energy solutions, the most reasonable source is from unconventional reservoirs. As the name “unconventional” implies, different and challenging approaches are required to characterize and develop these resources. This Special Issue covers some of the technical challenges for developing unconventional energy sources from shale gas/oil, tight gas sand, and coalbed methane.
Download or read book Performance Evaluation of Horizontal Wells With Multistage Fractures in Tight Formations by Considering Non Darcy Effect and Fracture Dynamics written by Liwu Jiang and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance evaluation of fractured wells has attracted increasing attentions since horizontal drilling and hydraulic fracturing technologies have been successfully and efficiently applied in tight formations; however, such an evaluation process is physically complex and mathematically challenging due to the composite effects of non-Darcy flow within fractures and fracture dynamics including complex fracture geometry, fracture network, and stress-sensitive permeability. It is of fundamental and practical importance to evaluate the production performance of a fractured well by taking the aforementioned composite effects into account in a consistent and accurate manner. A new slab source function was developed in the Laplace domain for improving the prediction accuracy on the early time transient pressure response which can take the fracture width into account. The semi-analytical method was used to solve the fluid flow problem through such hydraulic fractures each of which is discretized into small segments, while continuity equations at the interface of such discretized fracture segments were applied to generate the coupled matrix-fracture flow model. The effect of complex fracture geometry and shape-dependent conductivity on the transient pressure response are then examined and discussed. The fracture width is found to affect the early time transient pressure response, while the shape-dependent conductivity imposes a key impact on the transient pressure behaviour for the early and intermediate periods. A coupled matrix-fracture flow model is then proposed and solved in the Laplace domain with consideration of the aforementioned composite effects which may escalate the nonlinearity of the governing equations. An iterative method was developed to deal with the nonlinearity caused by non-Darcy flow in fractures, while the Pedrosa's transform formulation and perturbation technique is used to weaken and linearize the nonlinear effect caused by stress-sensitive permeability. It is found that the non-Darcy effect dominates the early time flow regime, while stress-sensitive effects in fractures and matrix mainly affect the transient pressure response for the intermediate- and late-stage flow regimes. The Laplace-transform difference method was further adopted to extend the current simplified fracture models more closely to reality by taking complex fracture networks into account. The fracture network is first discretized into small segments, and the finite difference method in the Laplace domain can be used to solve the fluid flow problem through such complex fracture systems. Furthermore, the effect of fractal-like discrete fracture network on the transient pressure behaviour can be examined, while the combined effects of complex fracture networks and stress-sensitive permeability can then be analyzed. Transition flow regime is identified for the scenarios with discrete natural fracture networks which can be affected by the stress-sensitive permeability in natural fractures. All the theoretical models have been validated and then extended to field cases. Type curves are generated and beneficial to examine the effect of each factor on the transient behaviour for horizontal wells with multistage fractures in tight formations under various conditions. The discrepancy between the real field pressure data and the traditional type curves without non-Darcy and stress-sensitive effects can be used to evaluate the degree of these two effects. Two new flow regimes including the fluid feed and transition flow regimes occurred in real field pressure tests can be employed to quantify the complexity of the hydraulic and natural fracture networks, respectively.

Download or read book A Semi analytic Solution for Flow in Finite conductivity Vertical Fractures Using Fractal Theory written by Manuel Cossio Santizo and published by . This book was released on 2012 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exploitation of unconventional reservoirs goes hand in hand with the practice of hydraulic fracturing and, with an ever increasing demand in energy, this practice is set to experience significant growth in the coming years. Sophisticated analytic models are needed to accurately describe fluid flow in a hydraulic fracture and the problem has been approached from different directions in the past 3 decades - starting with the use of line-source functions for the infinite conductivity case, followed by the application of Laplace Transforms and the Boundary-Element Method for the finite-conductivity case. This topic remains an active area of research and, for the more complicated physical scenarios such as multiple transverse fractures in ultra-tight reservoirs, answers are presently being sought. Fractal theory has been successfully applied to pressure transient testing, albeit with an emphasis on the effects of natural fractures in pressure-rate behavior. In this work, we begin by performing a rigorous analytical and numerical study of the Fractal Diffusivity Equation and we show that it is more fundamental than the classic linear and radial diffusivity equations. Subsequently, we combine the Fractal Diffusivity Equation with the Trilinear Flow Model, culminating in a new semi-analytic solution for flow in a finite-conductivity vertical fracture which we name the "Fractal-Fracture Solution". This new solution is instantaneous and has an overall accuracy of 99.7%, thus making it comparable to the Trilinear Pseudoradial Solution for practical purposes. It may be used for pressure transient testing and reservoir characterization of hydrocarbon reservoirs being produced by a vertically fractured well. Additionally, this is the first time that fractal theory is used in fluid flow in porous media to address a problem not related to reservoir heterogeneity. Ultimately, this work is a demonstration of the untapped potential of fractal theory; our approach is very flexible and we believe that the same methodology may be extended to develop new reservoir flow solutions for pressing problems that the industry currently faces.
