electro-facies is a unit of the vertical sediments sequence on the wire-line logs that can be differentiated from the upper and lower units. for detection of the electro-facies interval in kangan and upper dalan formations in south pars gas field, wire-line log and core data analysis (wells a, b, c and d) were used. note, only core data analysis in well a were available. first, thin-sections st...

wellbore instability is a quite common event during drilling, and causes many problems such as stuck pipe and lost circulation. it is primarily due to the inadequate understanding of the rock properties, pore pressure, and earth stress environment prior to well construction. this study aims to use the existing relevant logs, drilling, and other data from offset wells to construct a precise mech...

BACKGROUND The purpose of this study was to compare postoperative intraocular pressures and percentage of vitreous cavity gas fill one day following 25-gauge pars plana vitrectomy with 20% versus 25% sulfur hexafluoride (SF6) gas fill. METHODS This was a retrospective review of 187 consecutive cases of 25-gauge pars plana vitrectomy with complete fluid/gas exchange. The main outcome measures ...

The amine regenerator of acid removal unit in South Pars Gas Complex, Assalouyeh, Iran was modeled. This model was fitted to assess the large scale columns and allow application of solar thermal energy for production of low pressure steam. Heat transfer fluids including Therminol oil, sulfur, or salt melt could be applied to yield thermal energy from a solar collector and to store and transfer ...

The environment, the climate and human health are largely exposed to gas flaring (GF) effects, releasing significant dangerous gases into atmosphere. In last few decades, remote sensing technology has received great attention in investigation. Pars Special Economic Energy Zone (PSEEZ), located south of Iran, hosts many natural oil/gas processing plants petrochemical industries, making this area...

Separators are a vital part of almost every oil and gas production facility. Because their importance, optimal separator design is critical. Semi-empirical method conventional more primitive way determining the dimensions for separators. However, because simplifying assumptions used to derive semi-empirical correlations, this can only be obtain rough estimate dimensions. In study, novel hybrid ...

persian gulf and its coastal areas are the world's largest source of crude oil and related industries govern the region. one of the contaminants in this area is heavy metals associated with oil spill. more importantly, vanadium, nickel and zinc can be named in this regard. in this study, the contamination of northern coasts of persian gulf is selected to investigate for trace metals of v, ni, c...
