... uncertainties in the petrophysical characterisation of reservoirs should be a common and standard approach, but a unique robust methodology is not yet available off-the- shelf . Moreover, it is not granted that a unique approach may prove equally robust in all environments. It is therefore mandatory to develop...

... quality of log data; acquisitions that do not cover the entire interval of interest. Therefore a workflow has been developed to improve the knowledge of the drilled formation in case of poor dataset, focusing on qualitative characterisation of drill cuttings, both as macroscopic samples and thin sections...

... by ENI-Agip to reduce the incidence of wellbore instability problems while drilling. The technical background of this procedure is the acoustic characterisation of drilled cuttings, which can be achieved with two different experimental devices. One device is called ‘PUC’ (pulsed ultrasound on cuttings...

The results of both methods are reported. fingerprint remediation of hydrates paraffin remediation api characterisation chemical treatment...

... composed of fluviatile sediments characterised by strong facies heterogeneities and crossed by some sub-seismic faults. The geological study was carried out using: * a cluster analysis process on logs * non stationary facies simulations * petrophysical simulations * a strong integration...
