Field and Scott Smith [Field, M., Scott Smith, B.H., 1999. Contrasting geology and near-surface emplacement of kimberlite pipes in southern Africa and Canada. Proc. 7th Int. Kimb. Conf. (Eds. Gurney et al.) 1, 214–237.] propose that kimberlite pipes can be grouped into three types or classes. Classical or Class 1 pipes are the only class with characteristic low temperature, diatreme-facies kimb...

Identification of the geological facies and their distribution from seismic and other available geological information is important during the early stage of reservoir development (e.g. decision on initial well locations). Traditionally, this is done by manually inspecting the signatures of the seismic attribute maps, which is very time-consuming. This paper proposes an application of the Expec...

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...

Gas and oil reservoirs have been the focus of modeling efforts for decades as an attempt to locate zones with high volumes. Certain subsurface layers and layer sequences, such as those containing shale, are known to be impermeable to gas and/or liquid. Oil and natural gas then become trapped by these layers, making it possible to drill wells to reach the supply, and extract for use. The drillin...

A distributed neural network, running on a large transputer-based parallel computer, was trained to identify the presence of the main lithographical facies types in a particular oil well, using only the readings obtained by a log probe. The resulting trained network was then used to analyse a variety of other wells, and showed only a small decrease in accuracy of identiication. Geologists class...

In oil and gas industry, oil is produced from wells drilled into the oil reservoirs. A thorough understanding and characterization of the subsurface is crucial to sustainable management of a reservoir. The subsurface, however, is largely heterogeneous and oil is not present everywhere. For our study area, the reservoir rock is categorized as three facies: brine sand, oil sand and shale, and it ...

Introduction: Over the past several years, we have presented new data and proposed a cold-based glacial hypothesis for the Tharsis Montes fan-shaped deposits [14], which were first identified and analyzed using Viking data [5-8]. Based on stratigraphic relationships with young lava flows in Tharsis, we know that the deposits are of midto late-Amazonian age [8,9], but we have little information ...

The Epanomi gas field discovery during the 1980s at eastern fringe of Thermaikos Basin in Northern Greece proved existence an active petroleum system area. Seismic and drilling exploration programs area provide data to study Cenozoic clastic sequence Basin. This aims recognize, through core well-log data, wide range facies associations from different depositional environments, which contribute ...
