Abstract
The petrophysical characterisations are one of the most useful and important tools available to petroleum geologist. The petrophysical characterisation have been evaluated to Beda Formation though the analysis of open hole well logging records of four exploratory and development wells, distributed in the Beda Formation of Sirt basin, Libya. These available well logging records have been analyzed though utilizing the petrophysics software (for determining the petrophysical parameters). This is to identify the lithological constituents and saturation parameters. The litho saturation analysis of Beda Formation of the studied wells indicates that it is mainly. The analytical Formation evaluations of some cross plot (eg interval transient time & neutron porosity) reveal lithological facies change with different deposition environment. It consists mainly of mixture of limestone and dolomite with subtidal fossiliferous as indicated …
