among all the geophysical techniques, the magnetotelluric method has improved considerably in recent years and is widely being used in hydrocarbon exploration especially in regions where reflection seismic has difficulties. areas which are covered with high velocity rocks in the near surface are most popular cases. a huge high resolution magnetotelluric investigation was conducted in the sehqan...

shear and compressional wave velocities along with other petrophysical logs, are considered as upmost important data for hydrocarbon reservoirs characterization. shear wave velocity (vs) in well logging is commonly measured by some sort of dipole logging tools, which are able to acquire shear waves as well as compressional waves such as sonic scanner, dsi (dipole shear sonic imager) by schlumbe...

Abstract The Asmari reservoir in southwest Iran has been producing oil continuously for over 50 years. However, due to an essential pressure decline, the is now a potential candidate injection projects. geomechanical analysis successful operation enhance production and address possible challenges. An accurate estimation of necessary maintain optimal conditions during process reduce risks. In th...

Abstract Porosity and facies are two main properties of rock which control the reservoir quality have significant role in petroleum exploration production. Well seismic data most prevalent information for characterization. such as logs prepare adequate vertical resolution but leave a large distance between wells. In comparison, three-dimensional can more detailed characterization inter-well spa...

In this research, totally 610.4 meters of the Asmari Formation are studied in two stratigraphic sections on Bavan Mountain an Sarvestan section in Fars province, Iran. The indexed microfacies are carefully determined through studying of 230 thin sections.This research shows that the indexed microfacies are mudstone, wackestone, packstone, prainstone and the amount of microfacies elements such a...
