Depositional Facies and Petrophysical Characterization of the Leonardian Carbonate (Lower Clear Fork), Tex-Mex, S.E. Field, Central Basin Platform, West Texas
… requires an understanding of the variability in depositional facies in terms of mineralogy, depositional textures and structures, and an assessment of its petrophysical properties. As of December 2023, cumulative production of hydrocarbon from the Tex-Mex, S.E. Field reached about 88,308 barrels …

Petrophysical lithofacies modeling of the upper Pennsylvanian Cline Shale in the Midland Basin, West Texas.
… of west Texas. This study compares core-observed depositional facies to petrophysical well logs within the Gunn36 #1 well (API# 4222737197) of Howard County, Texas in order to identify predictors of organic richness and carbonate content for use in Cline Shale mapping. A depositional facies model …

Petrophysical facies mapping of the Pennsylvanian Cline Shale, Midland Basin, West Texas.
… Basin, west Texas. This study evaluates the depositional, stratigraphic and petrologic controls on Cline Shale reservoir quality and their spatial distribution as determined from core-calibrated petrophysical facies across the study area. Nine depositional facies were observed and described …

PALAEOECOLOGY, PALAEOENVIRONMENTAL ANALYSIS AND THEIR APPLICATION TO SEQUENCE STRATIGRAPHY: LOWER CRETACEOUS, LUSITANIAN BASIN, PORTUGAL
… data can provide key information on depositional environments. This may be critical to the interpretation of marine sedimentary cycles and the recognition of ancient cycles and sequences. Although many recent studies have attempted to combine palaeoecology and sequence stratigraphy, …

Integrated geological and petrophysical investigation on carbonate rocks of the middle early to late early Canyon high frequency sequence in the Northern Platform area of the SACROC Unit
… on core descriptions, four different sub-tidal depositional facies were defined in the Canyon 2 HFS. Identified depositional facies were grouped into three different reservoir rock types in respect to their rock fabrics in order for the HFC scale petrophysical reservoir rock type characteristic …

Complex Fluid Dynamics: From Laminar to Geophysical Flows
… microbial communities are highly correlated with depositional facies, we demonstrated that this is a consequence of tight correlations between aqueous chemistry and the underlying travertine. We show how these correlations can be used to reconstruct ancient depositional environments. We also …

Stratigraphic partitioning and reservoir distribution of the Late Devonian to Early Mississippian Exshaw Formation, Western Canada Sedimentary Basin.
… descriptions from 18 wells. Four basinal Exshaw depositional facies were identified, and four sequence stratigraphic surfaces were correlated across the study area. Geologic attributes were mapped to identify hydrocarbon potential "zones". Future exploration initiatives should target the Lower …

Upscaling Lithology and Porosity Types from Microscopic to Core Domain with Thin Section Petrography, Dual Energy CT, and Rock Types: Creation of Diagenesis and Porosity Type Logs
… their inter buildup sediments, the three main depositional facies, which underwent a wide range of diagenetic alteration pathways, was an adequate sample set to develop and test this new approach. Fractions of diagenetic calcite and diagenetic porosity were upscaled to the core scale using …

Depositional characterization of the Eau Claire Formation at the Illinois Basin - Decatur Project: facies, mineralogy and geochemistry
… upper unit. Within the Eau Claire, four major depositional facies exist within a tidally influenced, shallow marine depositional environment. These include (Unit A) intertidal mixed sand/mud flats and tidal channels of the foreshore environment; (Unit B) subtidal deposits of the offshore …

The relationship of Permian San Andres facies to the distribution of porosity and permeability in the ODC field, Gaines County, Texas.
… discontinuity, and an investigation of the depositional and diagenetic processes controlling porosity and permeability was made using data including five well cores and corresponding core lab reports. Preliminary analysis of the five San Andres cores involved detailed logging to determine …

Hazard Identification and Coastal Stratigraphy in Crescent Harbor, Northeast Whidbey Island, Washington
… Analysis of the modern-day position of depositional facies indicates subsidence from a high marsh to a tidal-flat environment representing an estimated 1.7 m elevation change. The timing of subsidence fits within the dates of a rupture found on the nearby Utsalady Point fault between …

Sedimentary and petrologic analysis of the Mississippian Price Formation at Sherwood Lake, West Virginia
Depositional facies determinations of the upper member of the Price Formation were made based on detailed descriptions of the six outcrops exposed along Sherwood Lake Road, Greenbrier County, West Virginia. Units were placed into one of seven facies: fluvial, distributary channels, crevasse-splays, …
