The sand intervals of the Lower Goru Formation of the Cretaceous age, widely distributed in the Middle and Lower Indus Basin of Pakistan, are proven reservoirs. However, in the Sawan gas field of the Middle Indus Basin, these sandstone intervals are very deep and extremely heterogeneous in character, which makes it difficult to discriminate lithologies and fluid saturation. Based on petrophysic...

avo analysis is a technique which is widely used in industry and is applied on seismic prestack data. results from changes in seismic wave reflection amplitude versus offset can be used in extracting elastic properties and hence lithology and reservoirs pore fluid identification. before performing avo analysis studies, processing steps should be ensured that changes in reflection amplitude are ...

Wellbore stability evaluation is one of the important applications rock mechanics and should be regarded to prevent instabilities that may develop in wells for various reasons (such as complex field conditions, interaction between drilling fluid, directional etc.). The saturation rocks by fluids causes significant changes on mechanical properties rocks. However level these variations changed du...

انجام عملیات شکست هیدرولیکی سهم قابل توجهی در افزایش تولید نفت و گاز در دنیا داشته است. اگرچه بیش از 60 سال است که در صنعت نفت دنیا شکست هیدرولیکی با موفقیت اجرا می شود، اما در ایران گزارشی از اجرای موفق این عملیات ارایه نشده است. همین امر لزوم توجه هر چه بیشتر دانشمندان ایرانی به این مهم را آشکارتر می سازد. در مدل ایجاد شده توسط نرم افزار آباکوس، مدل سازی چاه به صورت استوانه ای درون بلوک سه ب...

A novel two-stream relativistic klystron amplifier (RKA) is presented in which the amplification of stimulated beam modulation is achieved via the unstable two-stream interaction rather than the use of passive cavities. After a calculation of the limiting current, the amplification and saturation of the stimulated beam modulation are analyzed using a cold-fluid model and particle-in-cell simula...

A new, closed-form hysteretic model of the capillary pressure-saturation and relative permeability-saturation relationship has been implemented into ITOUGH2. The hysteretic capillary pressure function is based on the van Genuchten model, with a modified version of the dependent domain model of Mualem to describe the scanning curves. Hysteresis in the relative permeability relations is considere...

A novel, patented topping power cycle is described that takes its energy from a very high-temperature heat source and in which the temperature of the heat sink is still high enough to operate another, conventional power cycle. The top temperature heat source is used to evaporate a low saturation pressure liquid, which serves as the driving fluid for compressing the secondary fluid in an ejector...

In this work, e-Fe3N nanoparticles and e-Fe3Nbased magnetic fluid were synthesized by chemical reaction of iron carbonyl and ammonia gas. The size of e-Fe3N nanoparticles was tested by TEM and XRD. Stable e-Fe3Nbased magnetic fluid was prepared by controlling the proper ratio of carrier liquid and surfactant. The saturation magnetization of stable e-Fe3N-based magnetic fluid was calculated acco...

Abstract Saturation exponent is an important parameter in Archie’s equations; however, there has been no well-accepted physical interpretation for the saturation exponent. We have theoretically derived equations from Maxwell–Wagner theory on assumption of homogeneous fluid distribution pore space clay-free porous rocks. Further theoretical derivations showed that essence cementation water–air m...
