Available in PDF, EPUB and Kindle. Book excerpt: Normal faults are the primary structures that accommodate extension of the brittle crust. This volume provides an up-to-date overview of current research into the geometry and growth of normal faults. The 23 research papers present the findings of outcrop and subsurface studies of the geometrical evolution of faults from a number of basins worldwide, complemented by analogue and numerical modelling studies of fundamental aspects of fault kinematics. The topics addressed include how fault length changes with displacement, how faults interact with one another, the controls of previous structure on fault evolution and the nature and origin of fault-related folding. This volume will be of interest to those wishing to develop a better understanding of the structural geological aspects of faulting, from postgraduate students to those working in industry.

This book was released on 2012 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distinct, regionally continuous Cretaceous sand bodies are present beneath the outer continental shelf and upper slope off of New Jersey that encompasses much of the basin known as the Baltimore Canyon Trough (BCT). These sand bodies are possible candidates for liquid CO2 sequestration. This thesis aims to delineate and correlate four distinct sand units (Middle Sandstone, Upper Logan Canyon, Lower Logan Canyon Sand units, and Missisauga Unit) and their suitability for CO2 sequestration that requires sufficient depth, porosity, permeability, spatial continuity and presence of cap rock. I have analyzed geophysical logs and biostratigraphic data from 11 wells to identify the lithostratigraphic units of the BCT that are potentially suitable for carbon sequestration and have established three well log transects to demonstrate the spatial continuity of the target sand units. The correlation of lithostratigraphic units along the dip profiles reveals the stratigraphic patterns of the target sand units. The Middle Sandstone Unit has a progradational pattern throughout the study area, spanning the Coniacian through Santonian. Weak continuity and presence of hydrocarbon-bearing intervals indicate that this unit is not suitable for sequestration. The Upper Logan Canyon Sand Unit has a progradational pattern, spanning the Albian through Cenomanian. This sand body has a spatial continuity in the northeastern part of the BCT area and includes thick porous sandstone beds sealed with impermeable rocks above, suggesting potential for sequestration. The Lower Logan Canyon Sand Unit follows a retrogradational pattern, spanning the Aptian through Albian. The Lower Logan Canyon Sand Unit promises more continuity towards the south, unlike the upper unit. The Lower Logan Canyon Sand Unit is more favorable as a sequestration target. The Missisauga Unit has a progradational pattern, spanning the Hauterivian through Aptian. This unit is very thick and continuous throughout the study area, including abundant porous sand beds sealed with impermeable beds. However, many gas-bearing intervals are present within this deeply buried unit, and the age control is ambiguous, thus, making it a less favorable to unfavorable sequestration target.

This book was released on 2012 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heightened industry focus on the Upper Cretaceous (Cenomanian-Turonian) Eagle Ford has resulted from recent discoveries of producible unconventional petroleum resource in this emerging play. However, little has been published on the facies and facies variabilities within this mixed carbonate-clastic mudrock system. This rock-based study is fundamental to understanding the controls, types, and scales of inherent facies variabilities, which have implications for enhanced comprehension of the Eagle Ford and other mixed carbonate-clastic mudrock systems worldwide. This study utilizes 8 cores and 2 outcrops with a total interval equaling 480 feet and is enhanced by synthesis of thin section, XRD, XRF, isotope, rock eval/TOC, and wireline log data. Central Texas Eagle Ford facies include 1) massive argillaceous mudrock, 2) massive argillaceous foraminiferal mudrock, 3) laminated argillaceous foraminiferal mudrock, 4) laminated foraminiferal wackestone, 5) cross-laminated foraminiferal packstone/grainstone, 6) massive bentonitic claystone, and 7) nodular foraminiferal packstone/grainstone. High degrees of facies variability are observed even at small scales (50 ft) within the Eagle Ford system and are characterized by pinching and swelling of units, lateral facies changes, truncations, and locally restricted units. Facies variability is attributed to erosional scouring, productivity blooms, bottom current reworking, and bioturbation. At the 10-mile well spacing scale and greater, the data significantly overestimates intra-formational facies continuity but is successful in defining the following four-fold stratigraphy: The basal Pepper Shale is an argillaceous, moderate TOC, high CGR and GR mudrock. The Waller Member is a newly designated name used in this study for an argillaceous and foraminiferal, high TOC, massive mudrock with a generally moderate CGR and GR profile. The Bouldin Member is a high energy, carbonate-rich (foraminiferal), low TOC, low and variable CGR but high GR zone. Finally, the South Bosque Formation is an argillaceous and foraminiferal, moderate TOC, massive and laminated mudrock with a moderate CGR and GR signature. GR logs alone are inadequate for determination of facies, TOC content, depositional environment, and sequence stratigraphic implications. Using integrated lithologic, isotopic, and wireline log data, cored wells in the study area are correlated across the San Marcos Arch. Geochemical proxies (enrichment in Mo, Mn, U, and V/Cr) indicate that maximum basin restriction occurred during deposition of the Bouldin Member. Bottom current activity influenced depositional processes and carbonate sediment input was driven by water column productivity. These primary controls on Eagle Ford stratigraphy and character are independent from eustatic fluctuation, rendering classical sequence stratigraphy unreliable.

This book was released on 2019 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This analysis allowed for the construction of a comprehensive architectural framework connecting the aforementioned basins and the generation of detailed stratigraphic correlations and cross sections. Hand-contoured isochore maps were created for each of the six Niobrara lithofacies intervals, as well as for all Cretaceous units from the Cloverly Formation to the top of the Lower Cody Shale. Gamma ray logs were then digitized, allowing shale volume calculations for each of the six Niobrara lithofacies. The resulting data are presented as contour maps that denote different lithofacies within each interval. Results indicate that the mechanisms by which the Niobrara interval thickens from east-to-west are controlled by a regional west-to-east depositional trend with localized variation in depositional strike over time.

This book was released on 2019 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite collection of extensive subsurface data, the icehouse climatic forcing and tectonic modification of the Wolfcampian Hueco carbonates have frustrated attempts to adequately link shelfal and time-equivalent basinal depositional patterns. This study attempts to create a stratigraphic framework for correlating eastern Central Basin Platform Hueco shelfal carbonates and Wolfcamp Shale basinal stratigraphy by generating core-based vertical facies successions, wireline log and seismic-derived stratal architecture and sedimentation patterns, and isopachs along a contemporaneous shelf-to-basin depositional profile. Where available, fusulinid biostratigraphic control from the Midland Farms field area, provided by Dr. Greg Wahlman, constrained correlations, as did basinal palynologic data collected by Fasken Oil and Ranch. A total of 1,569 ft of core was described from the Midland Farms Deep Unit132, 101, 135, and 74 wells, the Midland Farms Unit 37 and AX-5, the Midland Farms Operating 3, and the Fasken Fee AL-910 and BI-307 wells. Thirteen depositional facies are recognized, which are grouped into seven facies tracts. Two depositional sequences were interpreted on the basis of 1D core lithofacies stacking patterns and were linked to selected shelf-to-basin log sections and seismic stratigraphic relationships. Shelf-to-basin correlations were made using a volume of nearly 2000 well-logs and 500 sq mi of 3D seismic data. The two major composite sequences recognized are termed the Lower Hueco and the Upper Hueco. The transgressive systems tract (TST) of the Lower Hueco Sequence LW-1 is characterized by phylloid algal patch reefs and associated bioclastic-oolitic grainstones that transition around the maximum flooding surface to skeletal packstones. The highstand systems tract of LW-1 records a shallowing-upward succession of slope, outer platform, and shelf crest facies. The LW-1 tract is capped by paleosols overlying shelf crest facies. The shelfal LW-1 is correlative to interbedded sediment-gravity flows and organic-rich siliciclastic mudstones in the Midland Basin, which represent platform shedding in conjunction with hemipelagic sedimentation. Despite the significant exposure recorded at the top LW-1, the mid-Wolfcamp unconformity is not identified as a significant erosive surface in this study, as suggested in other studies. The correlative mid-Wolfcampian interval in the adjacent basin is a stacked gravity flow complex that might represent a period of shelfal erosion related to exposure and/or tectonism. The transgressive systems tract of the Upper Hueco sequence UW-1 shows aggradation over the upper LW-1. The transgressive facies tract deepens to skeletal wackestone and is overlain by a thicker shallowing upward highstand systems tract that culminates in a large accumulation of grain-dominated packstone to grainstone facies which show evidence of subaerial exposure at the top Wolfcamp sequence boundary. This Wolfcampian-Leonardian unconformity is expressed by uppermost Hueco grainstones overlain by Leonardian deepwater basinal mudstones and gravity flows. Contemporaneous basinal sedimentation is mostly organic-rich siliciclastic mudstone with scarce sediment-gravity flow deposits. This study contributes an integrated model for the shelf-to-basin stratigraphic architecture of the Wolfcampian Hueco Group on the Central Basin Platform and the equivalent Wolfcamp Shale of the adjacent Midland Basin. Identifying controls on basinal sedimentation is important because allochthonous carbonate debris flows in the western Midland Basin can act both as drilling hazards and as reservoirs. Understanding the connections between the Hueco Group shelfal carbonate facies and sequences to the adjacent basinal stratigraphy could greatly improve reservoir prediction and development in the adjacent Wolfcamp Shale play.

This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eastward migration of the Caribbean plate relative to the South American plate is recorded by a 1100-km-long foreland basin which is oldest in the west (Maracaibo basin, 65-55 Ma) and youngest in the east (Columbus basin, eastern offshore Trinidad, 15-0 Ma). Regional transpression has caused lithospheric loading and flexure along the northern margin of South America creating a large foreland basin area which propagated from west to east as the Caribbean plate moved eastward relative to the South American plate. I have integrated 775 km of deep-penetration 2D seismic lines acquired by the 2004 BOLIVAR survey, 325 km of 1975 GULFREX seismic data, 8,000 km2 of industry 3-D seismic data, and published industry well data from offshore eastern Trinidad. Interpretation of seismic sections tied to wells reveals the following fault chronology: 1) middle Miocene thrusting along the Darien ridge related to highly oblique convergence between the Caribbean plate and the passive margin of northern South America; continuing thrusting and transpression in an oblique foreland basin setting through the early Pleistocene; 2) early Pliocene-recent low-angle normal faults along the top of the Cretaceous passive margin; these faults were triggered by oversteepening related to formation of the downdip, structurally and bathymetrically deeper, and more seaward Columbus basin; large transfer faults with dominantly strike-slip displacements connect gravity-driven normal faults that cluster near the modern shelf-slope break and trend in the downslope direction; to the south no normal faults are present because the top Cretaceous horizon has not been oversteepened as it is adjacent to the foreland basin; 3) early Pliocene-Recent strike-slip faults parallel to the trend of the Darien ridge and accommodate present-day plate motions. Active mud diapirism in the Columbus basin is widespread and is related to overthrusting and loading of upper Miocene-lower Pliocene age mud. Analysis of the 3-D seismic data reveals the presence of extensive gravity-flow depositional elements on the Columbus basin deepwater area, characterized by mass-transport deposits at the base, turbidite frontal-splay deposits, leveed-channel deposits, and capped by fine-grained condensed-section deposits. Deep basin wells drilled in recent years have proven that turbidites were transported into the Columbus basin deepwater during the Plio-Pleistocene. Analysis of these well results suggest that a deeper oil charge is present within the Columbus basin deepwater area. The primary uncertainty for this variable hydrocarbon system is whether fault or diapiric pathways connect the petroleum charge at depth with shallower reservoir rocks
