The objective of this study is to demonstrate the power of integrating rock physics theory, measurement and simulation to improve facies prediction in an unconventional limestone and shale reservoir. Reliable facies prediction is a challenge in unconventional reservoir characterization because of complex geological heterogeneities. Both deterministic and probabilistic approaches are commonly us...

Gran Dolina is a cavity infilled by at least 25 m of Pleistocene sediments. This sequence contains the TD6 stratigraphic unit, whose records include around 170 hominin bones that have allowed the definition of a new species, Homo antecessor. This fossil accumulation was studied as a single assemblage and interpreted as a succession of several human home bases. We propose a complete stratigraphi...

Introduction and General Characteristics: The fan-shaped deposits of the Tharsis Montes generally share three major facies: 1) Ridged facies, 2) Knobby facies, and 3) Smooth facies. The ridged facies consists of narrow, parallel, concentric ridges interspersed in places with small hills [1]. The hummocky or knobby facies consists of dense concentrations of small sub-km scale circular to irregul...

this study aims to identify favorable oil–gas reservoir facies in the chishan group of the wubao fault zone (gaoyou sag, subei basin, china) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. the results suggest that the chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

A detailed outcrop and sub-surface analysis was completed on the Peay Member sandstone (Frontier Formation) in the northeast Bighorn Basin, Wyoming, building on previous work by Clark (2010) and Hutsky (2011). Regional correlations reveal the sandstone body to be digitate in planform geometry, elongate along depositional dip, and restricted across depositional strike. It is interpreted to be th...

Abstract Gran Dolina is a cavity infilled by at least 25 m of Pleistocene sediments divided into 12 lithostratigraphic units and 19 sedimentary facies. These facies have been allochthonous facies, defined as sediment inputs from the outside, autochthonous generated within karst; but this division has challenged in recent works. In study, TD1 TD2 detailed studied use assessed. For that purpose, ...

1. Most attempts to describe the distribution of benthic macroinvertebrates in large rivers have used local (grab-scale) assessments of environmental conditions, and have had limited ability to account for spatial variation in macroinvertebrate populations. 2. We tested the ability of a habitat classification system based on multibeam bathymetry, side-scan sonar, and chirp sub-bottom seismics t...

Aquifer systems are considered in which measurements of logpermeability (Y) at a 1E-2 m support scale are unimodally distributed as taken within the 1E0 to 1E1 m scale of individual sand and gravel (sg) lithofacies, are weakly multimodal at the 1E1 to 1E2 m scale of assemblages of these facies, and are strongly multimodal at the 1E3 m scale of complexes of sg facies assemblages juxtaposed with ...
