4 when technology meets the geological vision Global e&p activity in new areas and new concepts requires greater technical flexibility and integration. As a world leader in interpretative and geological modelling technologies, eni e&p combines G&G data, geological field surveys and novel proprietary technologies from our in-house laboratories to produce comprehensive integrated studies. New discoveries are based both on past 75 years experience and on new geological concepts, that is, on a new geological vision. The development of new concepts is based on a deep understanding of field and laboratory hard data, advanced geological numerical and experimental modelling and the cumulative, shared knowledge of the geological community. Successful exploration is not a matter of chance, but the result of appropriate risk management, analysis of unexpected outcomes and the optimization of the geological evaluation based on a deep understanding of the earth.

5 sedimentology and stratigraphy modelling» 3D forward modelling of extension, geometry and volume of sedimentary sequences: support of exploration with source and reservoir multiple scenarios distributions at basin scale prediction of the location, extension, geometry and volume of reservoir bodies at a field scale structural dynamic modelling Model of the processes that affect basin evolution: rock properties, sedimentation erosion, extension/compression, compaction, salt injection/evacuation, faults: validation of restorations reconstruction of the thermal history evaluation of the stress history Dionisos - 3D developed with IFP» Process-based modelling of 3D deepwater meandering channel systems and associated deposits: estimate of net/gross and reservoir facies distribution/continuity within sinuous channel systems at the reservoir scale through time STructural finite Element Analysis Modelling (STEAM) advanced analogue simulators Computer controlled sand box apparatus: 4D evolution of structurally complex sedimentary basins conceptual geological models for poorly known exploration area Turmy developed with École des Mines Computer controlled sand box simulator developed with University of Parma

6 sedimentology 3D advanced visualization 3D viewer importing and visualizing all kind of geo-referenced data in 1D, 2D and 3D domain minero-chemostrat Metodology based on the mineralogical and chemical analyses: provides vertical and horizontal zoning in successions where the usual stratigraphic tools fail GEometry of Carbonate Objects (GECO) 3D viewer biostratigraphy Estimate of the depositional paleo-water depths, based on the faunal content of sedimentary rocks Minero-chemostratigraphy section from cuttings rock microcharacterisation Elaboration and computation of the Reservoir Efficiency Index (REI) a measure of the risk factors for reservoir quality: reservoir quality evaluation & prediction based on their depositional characteristic and subsequent evolution Ecolog - paleobatimetry estimation REI - Reservoir Efficiency Index

7 petroleum system modelling fracture analysis Geological driven tools for the statistical analysis of interpreted lineaments from continuity cube slices: input for fractured reservoir models fracture distribution at different scales evaluation of the deformation history Simba Plus Proprietary methodology and software package modelling all the geological and geochemical processes: prospect ranking defined by the probabilistic distribution of trapped hydrocarbons (volumes, types and quality) overpressure prediction & centroid definition Fracture probability map quantitative modelling of reservoir properties Methodology and software tools modelling the diagenetic processes: assessement of the conceptual model in terms of mass balance, kinetic and thermodynamic estimate and production of the effects of the diagenetic process on porosity Migration & accumulation map Pressure map Gas filling probability map Toughreact - Rockware Software

8 production allocation Geomolecular technologies: high resolution molecular analysis monitoring of production in complex environments (offshore, smart completion) when Production Logging Tool (PTL) is not suitable near real time formation evaluation and reservoir characterisation Technology pioneered and developed by eni since the 1980 for analysing and interpreting gas content from drilling mud measured at the well site: HC characterisation optimization of data acquisition post well evaluation Production allocation workflow oil quality prediction A new method based on quantitative molecular alteration enables an improved assessment of petroleum biodegradation: prediction of API gravities of crude oils even when available in microquantities differentiation of in-reservoir alteration mechanisms Gas while drilling geological laboratories Biodegradation analysis In-reservoir alteration unconventional geochemistry tools molecular migration indexes to evaluate relative migration distances new age-specific biomarkers to improve the definition of the generating source presence, distribution, quality, quantity, origin and maturity of liquid hydrocarbons in all type of cuttings and cores regardless of where mud additives were used during drilling Geological laboratories of eni established in 1937
