a new chemical compound is developed at petroleum university of technology to enhance therecovery of the free imbibition process and simultaneously hinder asphaltene precipitation. thecompound is tested on heavy oil samples from marun oil field, bangestan reservoir. the effects ofthe chemical compound on viscosity, hydrocarbon composition, and average molecular weight ofthe heavy oil are invest...

Paleoclimate was reconstructed by the clay mineral assemblages of shale units of Pabdeh (PaleoceneOligocene), Gurpi (Upper Cretaceous), Kazhdumi (Albian-Cenomanian) and Gadvan (Aptian-Neocomian) formations in the Bangestan anticline. To compare with clay minerals assemblages in these formations, selected samples also taken from available formations in drilled wells in Ahvaz, Marun, Karanj, and ...

the aim of this research is to investigate the relationship between leader – member exchange and organizational citizenship behavior, and considering the mediating role of psychological empowerment and organizational commitment. the sample consisted of 250 employees of marun oil and gas producing company who were selected by simple random sampling method. the instruments which used in this rese...

Abstract In this study, the data at Idenak hydrometric station were used to predict inflow Maroun Dam reservoir. For purpose, different models such as artificial intelligence, Holt-Winters and hybrid used. Partial mutual information algorithm was determine input parameters affecting modeling monthly by intelligence models. According Hempel Akaike criterion, we introduced with a 3-month lag, tem...

Abstract Shear wave velocity ( V S ) data from sedimentary rock sequences is a prerequisite for implementing most mathematical models of petroleum engineering geomechanics. Extracting such by analyzing finite reservoir cores very costly and limited. The high cost sonic dipole advanced wellbore logging service its implementation in few wells field has placed many limitations on geomechanical mod...

shear wave velocity (vs) data are key information for petrophysical, geophysical and geomechanical studies. although compressional wave velocity (vp) measurements exist in almost all wells, shear wave velocity is not recorded for most of elderly wells due to lack of technologic tools. furthermore, measurement of shear wave velocity is to some extent costly. this study proposes a novel methodolo...

One of the industries with high potential for energy saving is the petrochemical industry. Ethylene and propylene production plants (olefin plants) – as a part of the petrochemical industry – are very energy intensive. So, any try to improve their energy consumption efficiency could lead to a high amount of energy saving. Iran’s petrochemical industry uses old technologies and components and du...

Fractures are considered as one of the important structures in fractured reservoirs due to their effect on fluid currents and reservoirparameters such as porosity and permeability. Fracture parameters can only be directly calculated with core and image logs. Cores haveserious limitations, so image logs are the best method. The aim of this study is the systematic fractures analysis of the Asmari...
