Petrophysical properties calculation of (Hawaz f ormation in Murzuq basin southwetrn Libya)‎ using well log

Abstract EN

The well logs are one of the main tools applied to identify the important subsurface information.

The main Objective of this study is to evaluate Hawaz reservoir in purpose of estimating the hydrocarbon in place, rather than completions to increase the production and to enhance oil recovery from the study area.

This will be carried out through predicting the deposition environment and its relation to the Petrophysical model deduced from well logs.

Well logs are the main tool to confirm the core and cutting sample description (lithology and type of fluid or Gas) and correct the depth of these samples of each drilled well.

Consequentially, the well logs considered in this study were used to give the detail and accuracy of rock properties at any depth of Hawaz formation.

The Petrophysical results from calculations of Hawaz formation was:- Volume of shale 35%, porosity 20-25%, hydrocarbon saturation 60- 70%, permeability 100 – 1000md.

And also the mineral clay was Montmorillonite
