Available in PDF, EPUB and Kindle. Book excerpt: In East Texas, the Lower Cretaceous Travis Peak Formation is a gas-bearing sandstone with low-permeability and low-porosity. Hydraulic fracture treatments have been used to facilitate recovery and production. The potential for gas production from sandstones of the Travis Peak Formation in the Garrison Field, East Texas Basin, is evaluated by applying findings from drill cutting examinations to completion data of wells. In order to evaluate the effectiveness of hydraulic fracture treatments, a thorough understanding of the formation geology, production, and detailed studies of reservoir engineering properties are required. Drill cuttings provide a wide range of necessary information for this study. Samples evaluated enable (1) characterization of lithology, texture, and sedimentary fabric, (2) determination of mineralogy, including clay species, (3) analysis of porosity distribution and associated reservoir quality, and (4) determination of possible mineralogical influences on sandstone reservoir stimulation. For the purpose of this study, petrophysical analyses of well-logs provide reservoir parameters such as permeability, porosity, and water saturation. Stratigraphic, petrographic, and structural characterization of the Travis Peak Formation supply geologists and engineers with critical information that has enabled more effective completion of reservoirs. All allow for optimization of fracture treatments.

Available in PDF, EPUB and Kindle. Book excerpt: Gas production from low-permeability (tight) gas sandstones is increasingly important in the USA as conventional gas reservoirs are being depleted, and its importance will increase worldwide in future decades. Travis Peak tight sandstones have produced gas since the 1940s. In this study, well log, 2D seismic, core, and production data were used to evaluate the geologic setting and reservoir characteristics of the Travis Peak formation. The primary objective was to assess the potential for basinward extension of Travis Peak gas production along the west margin of the East Texas Basin. Along the west margin of the East Texas Basin, southeast-trending Travis Peak sandstones belts were deposited by the Ancestral Red River fluvial-deltaic system. The sandstones are fine-grained, moderately well sorted, subangular to subrounded, quartz arenites and subarkoses; reservoir quality decreases with depth, primarily due to diagenetic quartz overgrowths. Evaluation of drilling mud densities suggests that strata deeper than 12,500 ft may be overpressured. Assessment of the geothermal gradient (1.6[degrees]F/100 ft) indicates that overpressure may be relict, resulting from hydrocarbon generation by Smackover and Bossier formation potential source rocks. In the study area, Travis Peak cumulative gas production was 1.43 trillion cubic feet from January 1, 1961, through December 31, 2005. Mean daily gas production from 923 wells was 925,000 cubic ft/well/day, during the best year of production. The number of Travis Peak gas wells in "high-cost" (tight sandstone) fields increased from 18 in the decade 1966-75 to 333 in the decade 1996-2005, when high-cost fields accounted for 33.2% of the Travis Peak gas production. However, 2005 gas production from high cost fields accounted for 63.2% of the Travis Peak total production, indicating that production from high-cost gas wells has increased markedly. Along the west margin of the East Texas Basin, hydrocarbon occurs in structural, stratigraphic, and combination traps associated with salt deformation. Downdip extension of Travis Peak production will depend on the (1) burial history and diagenesis, (2) reservoir sedimentary facies, and (3) structural setting. Potential Travis Peak hydrocarbon plays include: updip pinch-outs of sandstones; sandstone pinch-outs at margins of salt-withdrawal basins; domal traps above salt structures; and deepwater sands.

Book excerpt: Data from eight fields producing from the Travis Peak Formation in the eastern East Texas Basin were used to define key engineering parameters for each field and to develop resource-reserve estimates. Field-average porosites range from 8 to 11 percent, and the median permeability for 191 wells is .088 md; field-average permeability ranges from .006 to .1 md. Gas productivity generally increases from south to north across the area studied with changes in the reservoir drive mechanism. Gas in place in the Travis Peak of East Texas Basin is estimated to be 19.5 Tcf, assuming 12 percent of the area of the basin is ultimately productive.

This book was released on 1987 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petrographic and geochemical studies were used to determine the diagenetic and burial history of Travis Peak sandstones in East Texas and to relate the diagenesis to permeability variations within the formation. Permeability in much of the formation has been reduced to less than 0.1 md by compaction, cementation and minor pressure solution. Travis peak sandstone is quartzarenite and subarkose, having an average composition Q95F4R1. The first authigenic cements to precipitate were illite, which coated detrital grains with tangentially oriented crystals, and dolomite. Next, extensive quartz cement, averaging 17% of the rock volume in well-sorted sandstone, occluded much of the primary porosity. Quartz is most abundant in the lower Travis Peak, in well-connected sandstone beds that were deposited in braided streams. Dissolution of orthoclase and albitization of plagioclase followed quartz cementation and occurred prior to mid-Cretaceous movement of the Sabine Uplift. Illite, chlorite, and ankerite precipitated after feldspar diagenesis. Oil migrated into Travis Peak reservoirs in the Late Cretaceous from Jurassic source rocks. Later deasphalting of the oil filled much of the remaining porosity in some zones near the top of the formation with reservoir bitumen.

Available in PDF, EPUB and Kindle. Book excerpt: Geomechanics investigates the origin, magnitude and deformational consequences of stresses in the crust. In recent years awareness of geomechanical processes has been heightened by societal debates on fracking, human-induced seismicity, natural geohazards and safety issues with respect to petroleum exploration drilling, carbon sequestration and radioactive waste disposal. This volume explores the common ground linking geomechanics with inter alia economic and petroleum geology, structural geology, petrophysics, seismology, geotechnics, reservoir engineering and production technology. Geomechanics is a rapidly developing field that brings together a broad range of subsurface professionals seeking to use their expertise to solve current challenges in applied and fundamental geoscience. A rich diversity of case studies herein showcase applications of geomechanics to hydrocarbon exploration and field development, natural and artificial geohazards, reservoir stimulation, contemporary tectonics and subsurface fluid flow. These papers provide a representative snapshot of the exciting state of geomechanics and establish it firmly as a flourishing subdiscipline of geology that merits broadest exposure across the academic and corporate geosciences.

Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to complement the author's 1996 book "The geology of fluvial deposits", not to replace it. The book summarizes methods of mapping and interpretation of fluvial depositional systems, with a detailed treatment of the tectonic, climatic and eustatic controls on fluvial depositional processes. It focuses on the preserved, ancient depositional record and emphasizes large-scale (basin-scale) depositional processes. Tectonic and climatic controls of fluvial sedimentation and the effects of base-level change on sequence architecture are discussed. Profusely illustrated and with an extensive reference to the recent literature, this book will be welcomed by the student and professional geologist alike.

Book excerpt: The Travis Peak (Hosston) formation constitutes a 1,000- to 5,000-ft-thick clastic wedge that formed two major depocenters along the north flank of the Gulf Coast Basin. The depocenters were dominated by fluvial-deltaic facies. A delta-fringe facies, including tidal flat and nearshore shallow-margin shelf facies, formed around the margins of the clastic wedge. These marginal-marine deposits within the upper Travis Peak are the most important productive facies of the formation within a nine-county area in East Texas. Sandstones in the Travis Peak are mineralogically mature. Low permeability and occlusion of porosity is primarily due to quartz overgrowths, authigenic clay, ankerite, and reservoir bitumen, a high-molecular-weight hydrocarbon residue. Within six Travis Peak gas fields in East Texas, porosity ranges from 8 to 11 percent and water saturation ranges from 28 to 44 percent within intervals of net pay. The permeability-thickness product is low in the southern part of the study area and increases toward the north. Upper limits of permeability range from 0.074 md (median value) to 0.084 md (thickness-weighted average), based on well tests that postdate fracture treatment. Within Chapel Hill field, three reservoir sandstone types were defined; sandstones with greatest lateral continuity were deposited as sandy tidal flats, including associated channel sandstones that trend northwest. Lower energy tidal-flat deposition is characterized by increased mud content of sandstones, and low marine transgression resulted in deposition of mudstone and muddy limestone.
