Rock samples tell the stories of the Earth.
Andrea Ortenzi, Technical Manager of geology laboratories in Bolgiano, is with us at the Eni research centre in San Donato Milanese, entry point for all samples of fluids and rock that are picked up by our wells around the world. "To get to know the history of a reservoir through samples, we must find discover it". What is behind the discovery of a deposit? Skills, innovation and the spirit of collaboration are the basis of our success, starting from the technologies for the study of the subsoil.
The first samples arrived in the Thirties and today constitute a great wealth. Core samples represent a vertical section of our reservoir of hydrocarbons. They tell us about the age of the rock, they measure porosity and permeability and allow the provision of the production of hydrocarbons in time.Read more
Core samples also allow us to understand the environment in which they are deposited. Eni is strongly committed to reducing the environmental impact of its activities and to guarantee the safety of the plant.
When core samples arrive in the laboratory they are studied by our technicians. The analysis allows us to reconstruct what happened inside our field over millions of years of its history. Here is how:
Each type of rock is characterised by certain values of density, which can be reconstructed. Thanks to Gravity Gradiometry (GG) technology, we can obtain valuable information on the type of rocks in the area and on their geometries in the subsoil. Eni has been a pioneer in the use of this type of data since the turn of the millenium.
The exploration is confirmed at the centre of our growth strategy.
