Abstract:

Abstract Modern deltas can be classified mainly into three types: fluvial dominated, wave dominated and tide-dominated delta. Geometry of shoreline and palaeoshore line, dominance of strand-plain environment and other geomorphological and sedimentological features indicate the present Godavari delta to be wave dominated delta system. Seismic reflection patterns are predominantly parallel to subparallel, indicative of delta plain environments. Progradational shingled and oblique (parallel) reflection configuration is observed in different seismic sequences. Stratigraphic hydrocarbon reservoirs

Abstract:

The influence of wave, tide and fluvial processes on shorelines varies considerably in and between coastal systems; this can result in the development of architecturally complex, mixed-process systems. Of these, tide-dominated systems produce some of the most heterogeneous deposits. The arrangement of reservoir elements generated by wave and fluvial processes in such tide-dominated systems can be, to some degree, systematic and predictable. This research details a modern, tide-dominated, fluvial-influenced, wave-affected coastal system. It presents geometric attributes for reservoir elements t

Abstract:

A delta is a type of sedimentary system that is closely related to oil and gas. Shallow-lake delta deposits in the Mesozoic-Cenozoic strata of China are of particular interest. This delta has significant oil and gas reserves that are developed widely. Based on a numerical simulation of the sand body of the shallow-lake delta, this study analyzes the influence of various sediment conditions on the sand-body development. The formation and distribution rules of the sand body are concluded and verified, and the results can effectively guide the exploration and development of oil and gas resources.

Much rarer is the reference to this ichnogenus in siliciclastic formations from the same age. In the Ordovician Lashkerak Formation cropping out at the Central Alborz mountains, Iran, <em>Thalassinoides </em>is a common trace fossil in wave-dominated shoreface complex and prodelta-mouth bar environments of a fluvial-dominated delta. We compare the Middle-to-Upper Ordovician branching networks of the Unit 2 of the Lashkerak Formation with the

ABSTRACT The Campanian Loyd Sandstone Member of the Mancos Shale (Loyd) along the Rangely Anticline, Piceance Basin, Colorado, contains a series of multi-meter-thick, heterolithic, coarsening-upward successions (CUSs) with internal clinoforms comprising low-angle-dipping (&lt; 5°), parallel-laminated sandstone beds interbedded with bioturbated flaser-wavy-lenticular bedded sandstone and siltstone. Loyd clinoforms are delta foresets composed of prodelta and delta-front deposits, including mouthbars. Many CUSs exhibit scours filled with bioturbated sandstone, or interbedded bioturbated sands

Abstract:

Major hydrocarbon and groundwater reservoirs are commonly hosted within coarse-grained alluvial deposits that contain a high degree of sedimentary heterogeneity. This paper presents a detailed characterization of the sedimentary heterogeneity of fluvial–deltaic deposits using architectural element analysis (AEA). Sedimentological data collected from outcrop faces exposing Late Quaternary glaciofluvial deposits in southern Ontario, Canada, is recorded in 31 sedimentary logs. These logs are used to identify nine different facies types, including gravel facies (Gm, Gp, Gt), sand facies (Sr, Sp, S

AbstractThe Paleocene-Lower Eocene N'kapa Formation has long been considered as an important groundwater and hydrocarbon resource in the eastern edge of the Douala Basin. The present study’s aim is to establish a possible link between the geological nature of this formation and the quality of potential aquifers using Gamma Ray well log, cuttings and outcrops through sedimentology and sequence stratigraphy studies. The results obtained from this study show that: lithofacies are dominated by clays, silts and sands/sandstones; gamma ray electrofacies are funnel-shaped to cylindrical-shaped with s

Offshore areas, along the North Shore of the St. Lawrence Estuary, have major lithostratigraphic and seismostratigraphic units that relate to the advance or retreat of the Late Wisconsinan Ice Sheet, subsequent marine transgression or regression, and reworking of postglacial deposits. Glacial diamicton and glaciomarine units (acoustic units 1 and 2) were emplaced between >18 and 14.5 ka, by basal meltout or ice-marginal sedimentation; they reflect ice-proximal sedimentation associated with ice-terminal stillstands. Deep-water muds (acoustic unit 3) represent ice-distal accumulation of glaci

Abstract. The post-glacial transgression up to the present sea level, which occurred about 5500 years B.P., deeply modified the coastal zone morphology, especially in the river mouth region, where, in a few millennia, the geographical pattern changed from an open bay to a delta environment. The Salum islands case illustrates this evolution. Sediments deposits and anthropic shell-middens, built in a time interval starting 6000 years B.P. up to now, based on radiocarbon dating, provide a chronological framework of the delta evolution. At first, the open post-transgression bay was subject to fill

The Quaternary stratigraphy of the Yangtze delta has been revealed by a deep (344.64 m) continuous borehole, the sediments of which are divided into four sections, the Early (Q1), Middle (Q2), and Late Pleistocene (Q3), and the Holocene (Q4). Six lithofacies include lacustrine, fluvial, coastal, drowned river channel, deltaic, and shallow marine in these time periods. The fluvial and lacustrine lithofacies prevailed during Q1and Q2; coastal and drowned river channel lithofacies periodically appeared in Q1, Q2, and Q3; shallow marine lithofacies dominated Q3; and deltaic lithofacies occurred in

River dynamics and sediment budget play a crucial role in shaping geomorphic variability of river channels and deltaic environments. Basin-scale human activities, including dam construction, induce alterations in river flow and sediment dynamics in the downstream channels and to the delta, and quantification of sediment source shift along downstream fluvial-deltaic systems is often uncertain. This study analyzed the river regime changes and sediment dynamics of a typical sediment-laden fluvial-deltaic system—the lower Yellow River (LYR) and the Yellow River Delta (YRD) —to assess the integrate

Permeability is an important characteristic for reservoir characterization and fluid flow modeling. Besides the more conventional sampling by core plugs and whole cores for measurements, the probe permeameter (sometimes called a mini-permeameter) has provided an alternative, nondestructive method to assess permeability. Application of the probe permeameter, however, may require some care before useful results can be obtained. In this study, we describe the testing and modifications of a commercially available probe permeameter. We identify some limitations and propose two modifications. With t
