Petrophysical Modelling For Reinterpreting Hydrocarbon Resorvoier of Kurachina Inhydrite Formation in Case of “Jazal Field”

Abstract

It is very impotent to know the distribution of reservoir and non-reservoir zones in carbonate formations, and determine their petrophysical properties that is necessary to evaluate carbonate reservoir so then we can invest it better.

Such study needs to do an accurate analysis and interpretation of the reservoir formations depending on the available data (seismic data and well data).

We did in this study full analysis of the well logs that was made in the wells of Jazal field, then we conclude the values of the different petrophysical parameters like: porosity (total, effective, and secondary porosity), clay volume, water and hydrocarbon saturation so we could then follow the variation of these properties vertically in each well After finishing the petrophysical study using ip "interactive petrophysices"  

We depended on the previous results to suggest petrophysical models using petrel program by distribute calculated parameters n wells on whole field   so we could follow the variation of these properties horizontally between the wells
