the prediction of porosity is achieved by using available core and log data; however, the estimationof permeability is limited to the scare core data. hence, porosity and saturation data through theframework of flow units can be used to make an estimation of reservoir permeability. the purposeof this study is to predict the permeability of a carbonate gas reservoir by using physical-basedempiri...

Intelligent reservoir characterization using seismic attributes and hydraulic flow units has a vital role in the description of oil and gas traps. The predicted model allows an accurate understanding of the reservoir quality, especially at the un-cored well location. This study was conducted in two major steps. In the first step, the survey compared different intelligent techniques to discover ...

تراوایی یکی از مهمترین پارامتر های مخازن نفتی است که در بسیاری از محاسبات و مدل سازی های مخزن نقش موثری ایفا می کند. یکی از روش های تخمین تراوایی، استفاده از مفهوم واحد های جریان هیدرولیکی hydraulic flow units (hfu) است. در نظر داریم با بکارگیری شاخص کیفیت سنگ( rqi ) ، شاخص منطقه/ زون جریانی ( fzi ) در این میدان روشی موثر جهت دسته بندی نوع سنگ ارائه کنیم. می دانیم که بهترین حالت برقراری ارتباط ...

the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
