A case study testing the effectiveness of neural networks for permeability determination in heterogeneous media using basic rock properties is presented. The dataset used consists 213 core samples from Morrow and Viola formations Kansas, United States. characterizing parameters cores are porosity (ϕ), water oil saturations (Sw So), grain density (GD), additional variables well logs induction re...

here in, an application of a new seismic inversion algorithm in one of iran’s oilfields is described. stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of geostatistics and seismic inversion algorithm. this method integrates information from different data sources with different scales, as prior informat...

Petrophysical properties of 585 rock samples from the Suhbaatar-Ulaanbaatar-Dalandzadgad geophysical profile in Mongolia are presented. Based on the rock classifications and tectonic units, petrophysical parameters (bulk density, magnetic susceptibility, intensity of natural remanent magnetization, and Köenigsberger ratio) of these rocks are summarized. Results indicate that (1) significant den...

A geological model was built for the Sadi reservoir, located at Halfaya oil field. It is regarded as one of most significant oilfields in Iraq. The study includes several steps, essential which importing well logs from six wells to Interactive Petrophysics software conducting interpretation and analysis calculate petrophysical properties such permeability, porosity, shale volume, water saturati...

Accurate estimation of hydrocarbon volume in a reservoir is important due to future development and investment on that reservoir. Estimation of Oil and Gas reservoirs continues from exploration to end of reservoir time life and is usual upstream engineer’s involvements. In this study we tried to make reservoir properties models (porosity and water saturation) and estimate reservoir volume hydro...

Abstract Hydrocarbons exist in abundant quantity beneath the earth's surface. These hydrocarbons are generally classified as conventional and unconventional depending upon their nature, geology, exploitation procedure. Since under depletion phase, have been a major candidate for current future hydrocarbon production. Additionally, investment research increased significantly its exploitation. Ha...

Nuclear magnetic resonance (NMR) has been widely used in petrophysical characterization of sandstones and carbonates, but little attention has been paid in the use of this technique to study petrophysical properties of coal...

Abstract The current work assesses the sandstones of Mutulla Formation as well limestone Thebes for being promising new oil reservoirs in Rabeh East field at southern portion Gulf Suez Basin. This assessment has been achieved through petrophysical evaluation wireline logs three wells (RE-8, RE-22 and RE-25). visual analysis data revealed that RE-25 Well is only demonstrating positive criteria f...
