Petrophysical and Geological study of Gsur oil Field, Sirt Basin

Abstract

Through our study on the F field of bridges oil-based on the geological and netrophysiological data obtained from the company, it shows us the following: The formation of hydrocarbons produced in this field is the Gir formation of the Ficha member and deposition in a shallow V and reserved marine environment in the lower Eocene, and the lithology structure of this reservoir is the dolomitas, the source rock of the formation Rakb and Rachmat Basmel, and petrophysiological information through which we conducted the calculations. We found that this formation has the characteristics of a good reservoir in terms of porosity as well as permeability. The volume of the original oil in the place in the Facha reservoir was estimated at 300,000,000 bbls. The established water saturation and net pay maps for the Facha reservoir have been made in order to determine if there is any special pattern of net pay and hydrocarbon saturation throughout the field. These maps show the water saturation and net pay variation and give a good indication for future drilling limitations to avoid drilling in a location where the porosity is low, less than the cutoff value.
