Abstract High-quality hydrocarbon source rocks are present in the upper Cretaceous layer western slope of Songliao Basin. Oil and gas have accumulated these at shallow edge basin, which has led to formation oil sand resources. This study uses back-propagation (BP) neural network method predict distribution reservoirs is first its kind China. First, based on basic data collected by core sample, ...

Monazite-(Ce) and xenotime-(Y) were found in the metacherts (pumpellyite–actinolite-facies conditions: 3 ≤ P ≤ 4 kbars and 300 ≤ T ≤ 350°C) of the Monte Figogna Unit, Sestri–Voltaggio Zone, Liguria, in Italy, as scattered submillimetric grains in pelitic beds and as euhedral crystals in both millimeter-thick quartz veins and open fissures. Their composition is comparable to those of known occur...

U-Pb dating of zircon was undertaken with the Beijing SHRIMP II (sensitive high resolution ion microprobe) on anamphibolite facies granodiorite and an almandine-albite granulite from the Santa Maria Chico Granulitic Complex, southern Brazilian Shield. This work was also done to unravel protolith ages which are often hidden in the array of partly reset data. The obtained metamorphic ages of the ...

a stratigraphic section from the tirgan formation was selected in arkan village nearby bojnourd city in order to study echinoderm fauna systematically. many specimens of echinoderms, especially toxasteridae which is associated with brachiopods were collected and studied systematically in this paper. microscopie slides were also prepared and studied. all slides contain benthic foraminifers and c...

The main purpose of this study is to estimate hydrocarbon potentialities Yamama Formation (Valanginian–Early Hauterivian) by using assessment technique links up between gamma ray spectrometry logs and other conventional open hole for determining the petrophysical properties units in Subba oil-field oil water contact as well. Lower (YB); considered reservoir unit, aptly composed shallow high dep...

Completion design for horizontal wells is typically performed using a geometric approach where the fracturing stages are evenly distributed along lateral length of well. However, this ignores intrinsic vertical and heterogeneity unconventional reservoirs, resulting in uneven production from hydraulic stages. An alternative to selectively complete intervals with similar superior reservoir qualit...

Zellweger syndrome (ZS) is a peroxisomal disorder with a multiple congenital anomalies, characterized by stereotypical facies, profound hypotonia, organ involvement including cerebral, retinal, hepatic, and renal. Herein, a 3-month-old female with ZS is presented who was referred because of increased liver enzymes (subclinical hepatitis), which was detected in work-up of her neck cyst, severe h...

History matching is used to constrain flow simulations and reduce uncertainty in forecasts. In this work, we revisited some fundamental engineering tools for predicting waterflooding behavior to better understand the flaws in our simulation and thus find some models which are more accurate with better matching. The Craig-Geffen-Morse (CGM) analytical method was used to predict recovery performa...

Rb–Sr and U–Pb isotopic data for granulite facies rocks, forming textural relics with respect to eclogite facies metamorphism in the Western Gneiss Region (WGR) of Norway, highlight the importance of textures and mineral reaction kinetics for the interpretation of geochronological data. Studied rocks from Bårdsholmen, southern WGR, were subjected to granulite facies metamorphism at 955 ± 3 Ma (...
