This book was released on 2009 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A recent U.S. Geological Survey (USGS) oil and gas assessment of the Powder River Basin, Wyoming and Montana, identified the Upper Cretaceous Mowry Shale and Niobrara Formation as the primary hydrocarbon sources for Cretaceous conventional and unconventional reservoirs. Cumulative Mowry-sourced petroleum production is about 1.2 BBO (billion barrels of oil) and 2.2 TCFG (trillion cubic feet of gas) and cumulative Niobrara-sourced oil production is about 520 MMBO (million barrels of oil) and 0.95 TCFG. Burial history modeling indicated that hydrocarbon generation for both formations started at about 0.60 percent Ro at depths of about 8,000 ft. At maximum depths, Ro for the Mowry is about 1.2 to 1.3 percent and about 0.80 percent for the Niobrara. The Mowry and Niobrara continuous reservoirs were assessed using a cell-based methodology that utilized production data. The size of each cell was based on geologic controls and potential drainage areas in analog fields. Current and historical production data were used to determine the estimated ultimate recovery (EUR) distribution for untested cells. Only production data from unconventional fractured shale reservoirs with vertical wells were used. For the Mowry, the minimum, median, and maximum total recovery volumes per cell for untested cells are (1) 0.002, 0.25, and 0.35 MMBO, respectively; and for the Niobrara (2) 0.002, 0.028, and 0.5 MMBO. Sweet spots were identified by lineaments and faults, which are believed to be areas having the greatest petroleum potential; an upper limit of 8,000 ft depth was defined by over pressuring caused by hydrocarbon generation. Mean estimates of technically recoverable undiscovered continuous resource for the Mowry are 198 MMBO, 198 BCF (billion cubic feet of gas), and 11.9 MMBNGL (million barrels of natural gas liquid), and those for the Niobrara are 227 MMBO, 227 BCFG, and 13.6 MMBNGL.

Available in PDF, EPUB and Kindle. Book excerpt: Petrophysical well-logs are incremental-depth records of rock, mineral, fluid, and other properties of the subsurface. Well logs and the practice of well-log interpretation by geologists and petroleum engineers represent a critical component of the exploration and assessment of potential hydrocarbon producing formations and reservoirs.The fundamentals of petrophysical well-log interpretation are presented in this monograph, which is a compilation of slide-oriented course notes and commentary created by the author over many semesters of undergraduate and graduate class-room instruction and is designed as a self-teaching guide with worksheets.Chapter 1 is an introduction to well-log interpretation, reviews discipline terminology, the types and uses of various well logs, and how the analyst might visually review logs in an effort to identify potentially productive zones of hydrocarbons. Chapter 2 introduces the reader the borehole environment and a view of the zones in a porous and permeable formation that has been invaded during drilling. The algorithmic steps are presented for computation of formation temperature from data on the log header.Chapters 3-7 present to the user the general information and characteristics of the various well logs including what individual well logs are designed to measure and how tool measurements are converted to appropriate units needed for hydrocarbon production assessment. Each chapter presents well-log analysis for two well-known Cretaceous formations: Glen Rose and Frontier.Chapter 8 reviews the critically important "Archie Parameters" that subsequently are used in Chapter 9 to compute the water saturations of the Glen Rose and Frontier formations using the Archie water-saturation equation. In prior worksheets, the reader is guided to the determination that the Frontier formation is a shaly sandstone and therefore the specific methods of "shaly-sandstone analysis" are required. Chapter 10 is a review of additional techniques used to progressively refine interpretation of the two formations through well-log analysis. Additional techniques demonstrated include guidance on the user answering the following questions: (1) Are the hydrocarbons calculated within Chapter 9 moveable? (2) Are the two formations "water-wet" or "oil-wet?" (3) What are the pore types within the Glen Rose? (4) Should the Glen Rose and Frontier formations individually make "water-free completions." Similar to the other chapters, the information acquired and computations by the user are oriented around worksheets so that final interpretations of each formation can be made.Chapter 11 introduces and extensively reviews techniques useful for the evaluation of hydrocarbon potential in unconventional shale reservoirs using the standard well-log suite comprised of resistivity, neutron porosity, and bulk density logs. The techniques will be presented along with four case studies of the gas-bearing Woodford Shale and the three oil-bearing shales (Permian Leonard shale and two Permian Wolfcamp shales).Although the focus of the self-guided components of the monograph are generally restricted to a few select formations. The monograph includes considerable information and examples of, the well logs, host-rock properties (sandstones, shales, ...), and reservoirs within other formations discussed include: Ordovician Gunton; Devonian Marcellus; Mississippian Barnett, Chester, Mission Canyon; Pennsylvanian Canyon, Springer, Morrow, and Upper Morrow; Permian Bone Springs, Glorieta, and San Andres; Triassic Montney; Cretaceous Lewis, Pictured Cliffs, and Woodbine.The slides and commentary in this monograph are expected to be useful to a broad range of petrophysical well log analysts as tools to practical application as well as ascending for the beginner the formidable learning curve of petrophysical well-log interpretation.
