in order to determine the physico-chemical characteristics of oils from upper sarvak and dariyan formations, 4 oil samples collected from reshadat and resalat oilfields were analyzed. physical properties of oils (e.g. the api gravity), indicates that dariyan oil in both resalat and reshadat oilfield is similar to (with low pour points and high sulfur contents) the oils from sarvak reservoir. ba...

Abstract The Cenomanian Sarvak oil reservoirs are distributed over large areas of the Persian Gulf basin. purpose this study is analyzing geochemical characteristics and their inter-relationships in Gulf, classification samples investigation possible causes genetic difference families. In previous studies, limited reservoir scarce oilfields were studied individually local interpretations made a...

In this work, the thermophysical properties of four mineral (paraffinic and naphthenic) synthetic (polyalphaolefin ester) base oils are measured. Knowledge these is vital importance for correct optimal formulation design lubricants, development equations state transport models that adequately represent their properties. Density, isothermal compressibility, thermal expansion coefficient, dynamic...

Mineral oils (also known as base oils, mineral base oils or lubricant base oils) are chemical substances prepared from naturally occurring crude petroleum oil. Crude oil is distilled first at atmospheric pressure and then under high vacuum to yield vacuum distillates and residual fractions that can be further refined to mineral oils. Mineral oils refined from petroleum crude oils are complex an...

for this study, asmari (oligo-miocene) and bangestan (cretaceous) reservoir oils from themarun oilfield were studied geochemically. gas chromatograms and stable isotopes of carbon and sulfur indifferent oil fractions were studied. normal alkanes nc15+ are as high as 93% with a saturate percentage up to53.9% which reveal a high maturity of asmari and bangestan reservoir paraffinic oils. carbon p...

physical and chemical properties of  crude oil, including viscosity and api gravity, are commonly inherited  from the  early organic matter, environmental conditions in which they were deposited and depth of burial of the source beds. api gravity increases in deeper burial due to higher thermal maturation of organic matter in the source rocks and consequently, generation of lighter saturated hy...

Two stratigraphic sections (Kuh-e-Rahmat and Kuh-e-Sabz) of Upper Cretaceous strata in the Interior Fars region (SW of Iran) were selected. Lower Cretaceous succession of Kuh-e-Rahmat was consisted of Dariyan, Kazhdumi Sarvak and Ilam Formations. The lower contact of the Sarvak Formation with Kazhdumi Formation is described as a transitional type whereas the upper contact of Sarvak Formation wa...

Liquid polymers are used in elastomeric compounds to modify their processing and final characteristics. The material is considered as a polymeric plasticizer substitute or supplement conventional like paraffinic aromatic oils, hydrocarbon resins. Their plasticizing effect contribution the crosslinking sulfur cured SSBR mixtures studied. Aromatic oil, aliphatic resin different liquid polymers, v...
