The Bakken formation in the Elm Coulee Field of the Williston Basin consists of three members: 1) upper shale member, 2) middle silty dolostone member, and 3) lower shale member. The upper and lower members act as excellent source rocks and the main reservoir is the middle member with an average porosity of 3 to 9% and average permeability of 0.04md. The Bakken oil play in this area is a stratigraphic trap with a pinch-out to the southwest and a diagenetic facies change in the northeast. The main production is interpreted to come from matrix permeability in the field area. However, the first year production trends from the Elm Coulee Field show areas of anomalously high production. This study used 3D seismic data from Crane Field, which is located in the southeastern part of the Elm Coulee Field, to investigate structures which might be responsible for the anomalous production trends at the Elm Coulee Field. We used post stack seismic conditioning and seismic attributes to amplify the structure of the basement. Further investigation revealed the presence of a pop-up structure in the central portion overlying a zone of basement deformation. This zone of deformation was interpreted to be composed of a left lateral wrench faulting system based on a model-driven approach. This study goes on further to map the structure and faults in 3 dimensions using a model driven approach, which reveals that the pop-up structure evolved from an obtuse angle left lateral step over system in the basement. In addition, the presence of this left lateral wrench fault network is interpreted to be related to a regional left lateral strike slip system - the Brockton Froid Fault Zone The fracture network characteristics in the middle member of the Bakken Formation are directly related to the local stresses generated by the interpreted left lateral wrench fault system in the study. There are two fracture sets- NE-SW and NW-SE. The structure and fracture network characteristics help explain the presence of regions of anomalously high EUR [CB1] values in the Elm Coulee Field. The regions of anomalously high EURs in the Elm Coulee Field may be regions where the middle member of the Bakken Formation has increased natural fracturing related to the local stresses induced by left-lateral oblique slip strike slip faults..

Enhanced Oil Recovery Field Case Studies bridges the gap between theory and practice in a range of real-world EOR settings. Areas covered include steam and polymer flooding, use of foam, in situ combustion, microorganisms, "smart water"-based EOR in carbonates and sandstones, and many more. Oil industry professionals know that the key to a successful enhanced oil recovery project lies in anticipating the differences between plans and the realities found in the field. This book aids that effort, providing valuable case studies from more than 250 EOR pilot and field applications in a variety of oil fields. The case studies cover practical problems, underlying theoretical and modeling methods, operational parameters, solutions and sensitivity studies, and performance optimization strategies, benefitting academicians and oil company practitioners alike. Strikes an ideal balance between theory and practice Focuses on practical problems, underlying theoretical and modeling methods, and operational parameters Designed for technical professionals, covering the fundamental as well as the advanced aspects of EOR
Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.
The volume is organized into three sections entitled Overview, Extensional Settings and Contractional Settings together with a glossary of terms having to do with strike-slip deformation, basin formation and sedimentation.
