“…Stratification in the lower part of the channel fill is dominantly cross-bedded, low-angle, inclined laminations and large-scale ripples, whereas the upper part is marked by asymmetric current ripples with mudstone drapes, fine-scale laminations, and dewatering structures (Figure 13c). Similar distributarychannel successions are observed in the modern Niger Delta (Oomkens, 1967(Oomkens, , 1974, Mississippi delta (Frazier, 1967), and lacustrine deltas in the Atchafalaya Basin (Tye and Coleman, 1988), as well as in outcrops from Pennsylvanian deltaic deposits of the Eastern shelf of the Midland Basin (Brown et al, 1973;Brown et al, 1990).…”

An analysis of 31 whole cores (1600 ft, 490 m) and closely spaced wireline logs (500 wells) penetrating the Lower Cretaceous (Cenomanian) lower Woodbine Group in the mature East Texas field and adjacent areas indicates that depositional origins and complexity of the sandstone-body architecture in the field vary from those inferred from previous studies. Heterogeneity in the lower Woodbine Group is controlled by highstand, fluvial-dominated deltaic depositional architecture, with dip-elongate distributary-channel sandstones pinching out over short distances (typically <500 ft [<150 m]) into deltaplain and interdistributary-bay siltstones and mudstones. This highstand section is truncated in the north and west parts of the field by a thick (maximum of 140 ft [43 m]) lowstand, incised-valley-fill succession composed of multistoried, coarsegravel conglomerate and coarse sandstone beds of bed-load fluvial systems. In some areas of the field, this valley fill directly overlies distal-delta-front deposits, recording a fall in relative sea level of at least 215 ft (65 m).Correlation with the Woodbine succession in the East Texas Basin indicates that these highstand and lowstand deposits occur in the basal three fourth-order sequences of the unit, which comprises a maximum of 14 such cycles. Previous studies of the Woodbine Group have inferred meanderbelt sandstones flanked by coeval flood-plain mudstones and well-connected, laterally continuous sheet sandstones of wave-dominated deltaic and barrier-strand-plain settings. This model is inappropriate, and a full assessment of reservoir compartmentalization, fluid flow, and unswept mobile oil in East Texas field should include the highstand, fluvial-dominated deltaic and lowstand valley-fill sandstone-body architecture.

“…Pennsylvanian Perrin Delta.-The Perrin Delta prograded into a Pennsylvanian cratonic basin, and is part of the Placid Formation of the Canyon Group, which consists of four thick limestones with interstratified clastic deposits (Brown et al 1990). Delta deposits representing parts of the Perrin Delta crop out west of Wizard Wells, Texas (Fig.…”

Using modern and ancient examples we show that river-dominated deltas formed in shallow basins have multiple coeval terminal distributary channels at different scales. Sediment dispersion through multiple terminal distributary channels results in an overall lobate shape of the river-dominated delta that is opposite to the digitate Mississippi type, but similar with deltas described as wave-dominated. The examples of deltas that we present show typical coarsening-upward delta-front facies successions but do not contain deep distributary channels, as have been routinely interpreted in many ancient deltas. We show that shallow-water river-dominated delta-front deposits are typically capped by small terminal distributary channels, the crosssectional area of which represents a small fraction of the main fluvial ''trunk'' channel.Recognizing terminal distributary channels is critical in interpretation of river-dominated deltas. Terminal distributary channels are the most distal channelized features and can be both subaerial and subaqueous. Their dimensions vary between tens of meters to kilometers in width, with common values of 100-400 m and depths of 1-3 m, and are rarely incised. The orientation of the terminal distributary channels for the same system has a large variation, with values between 123u (Volga Delta) and 248u (Lena Delta). Terminal distributary channels are intimately associated with mouth-bar deposits and are infilled by aggradation and lateral or upstream migration of the mouth bars. Deposits of terminal distributary channels have characteristic sedimentary structures of unidirectional effluent flow but also show evidence of reworking by waves and tides.

“…Cratonic basin and platform deltas are characterized by lateral rather than vertical development of facies, extensive cannibalization of the deltaic facies by the equivalent fluvial systems, irregular digitate geometries, and laterally extensive, bounding marine beds that may produce cyclothemic sequences (Brown 1979;Brown et al 1990). Cratonic basin and platform deltas are characterized by lateral rather than vertical development of facies, extensive cannibalization of the deltaic facies by the equivalent fluvial systems, irregular digitate geometries, and laterally extensive, bounding marine beds that may produce cyclothemic sequences (Brown 1979;Brown et al 1990).…”

“…High fluvial input combined with rapid subsidence of delta front sands into the underlying mud substrate resulted in deposition of wave-modified fluvial-dominated deltas. Pennsylvanian deltaic systems of the Midland Basin, Texas, exhibit changes in deltaic depositional style resulting from progradation across a shallow, stable platform to the contemporaneous shelf edge (Galloway and Brown 1972;Brown et al 1990). As sediment supply began to wane, wave reworking increasingly modified distributary mouth bars, producing arcuate beach-ridge complexes.…”

They formed in response to a complex array of geologic controls, notably the genesis of the sedimentary rocks that host most commercial energy resources. It is this genetic relationship between economic resources and environment that forms the basis for this book. Our grouping of petroleum, coal, uranium, and ground water may appear to be incongruous or artificial. But our basic premise is that these ostensibly disparate resources share common genetic attributes and that the sedimentological principles governing their natural distributions and influencing their recovery are fundamentally similar. Our combined careers have focused on these four resources, and our experiences in projects worldwide reveal that certain recurring geologic factors are important in controlling the distribution of commercial accumulations and subsurface fluid flow. These critical factors include the shape and stability of the receiving basin, the major depositional elements and their internal detail, and the modifications during burial that are brought about in these sediments by pressure, circulating fluids, heating, and chemical reaction.Since the first edition of this book in 1983, there has been a quantum leap in the volume of literature devoted to genetic stratigraphy and refinement of sedimentological principles and a commensurate increase in the application of these concepts to resource exploration and development. Two wholly new chapters, 11 and 16, have been added to accommodate these advances, two chapters (7 and 8) have been completely rewritten, and Chapters 3, 6, 9, 10, and 13 have been substantially revised.We review the spectrum of terrigenous (land-derived or siliciclastic as opposed to in-place or biochemical) clastic depositional systems and their component genetic facies, with emphasis on subsurface as well as field recognition. These range from the most proximal, subaerial, and generally coarse-grained alluvial-fan systems through fluvial, deltaic, shore-zone, ...
