Formation evaluatin from logging on cuttings

摘要

This paper presents an overview of a vast research project named Foramtion Evaluation 2000 that was undertaken by Agip SpA and was aimed at characterizing in real time the formations encountered during drilling by the mean of measurements on drill chips.Todate.the project has demonstrated the feasibility to obtian representative values of the P adn S wave velcities.rock strength and deformability,permeability,porosity,density,residual content and saturation.Further work is underway in order to gain access to hte pore size distribution,the thermal expansion and the conductivity of the rocks.
