Ordovician limestone-marl alternations in the Oslo-Asker District have been interpreted as signaling glacio-eustatic lowstands, which would support a prolonged "Early Palaeozoic Icehouse". However, these rhythmites could alternatively reflect differential diagenesis, without sedimentary trigger. Here, we test both hypotheses through one Darriwilian and three Katian sections. Our methodology con...

In order to determine the source and critical areas of wind Erosion, Sistan Plain, IRIFR-E.A method was applied. According to geomorphological investigations, the studied area consists of the following two main units namely: Pediment with 1 type and 8 geomorphological facies, and playa with 2 types of flatland and desert type that includes 9 geomorphological facies. On the basis of sediment, th...

Diminish of error ratio to expecting the lithology reservoir formation is considered as mean concerning geology nowadays. The aim research minimize wrong reading data extract facies by preparing using Interactive Petrophysics program (IP) make cluster analysis multi well logs data. Log Kirkuk oil field used in this included: Gamma ray (GR), sonic, neutron (N), bulk density (BD), Caliper and Res...

This work represents study the rock facies and flow unit classification for Mishrif carbonate reservoir in Buzurgan oil Field, which located n south eastern Iraq, using wire line logs, core samples petrophysical data (log porosity permeability). Hydraulic units were identified zone indicator approach assessed within each type to reach better understanding of controlling role pore types geometry...

The present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

Adenoid facies is a disorder which refers to the open-mouthed face of children who have long faces with adenoid hypertrophy. Hypertrophy of the lymphoid tissues in the throat (the adenoids) is the most common cause of nasal obstruction in children. The mouth is always open because upper airway congestion/narrowing has made patients obligatory mouth breathers. Persistent mouth breathing is seen ...

geological facies interpretation is essential for reservoir studying. the method of classification and identification seismic traces is a powerful approach for geological facies classification and distinction. use of neural networks as classifiers is increasing in different sciences like seismic. they are computer efficient and ideal for patterns identification. they can simply learn new algori...

tirgan formation with lower cretaceous age (barremian-aptian) in the kopet-dagh basin consists of carbonate and siliciclastic rocks (calcareous shale and sandstone) which conformably lay between siliciclastic rocks of shurijeh formation below, and marly sarcheshmeh formation at the top. in this study, tirgan formation in two stratigraphic sections of abgarm (77 m in thickness) and sirzar (46 m ...

Midto Upper Devonian strata of the lower Witteberg Group in the Cape Fold Belt of South Africa comprise three principal facies deposited in the shoreface and contiguous inner shelfalong a storm-dominated coastal zone. Weakly burrowed mudrock with variable minor proportions of wave-rippled sandstone (linsen, flasers, hummocky cross stratification [HCSJ) (facies 1) accumulated in the inner shelf ...
