We reproduce subsoil in high definition thanks to DVA technology.
One of the most significant examples of applications developed in-house in recent years is Depth Velocity Analysis (DVA) – a platform for the analysis of seismic data that allows us to obtain a 3D image of the subsoil as close as possible to reality. Erika Gentile, Eni coordinator for the processing of seismic data, tells us about the power of key software in our exploration.
It was 2009 when Eni engineer Clara Andreoletti received the Eni Award for a software package which enabled the analysis of seismic velocity. From that moment onwards, DVA technology became an indispensable working instrument for the study of the subsoil.
Know where to begin before starting: the first secret of Eni’s exploration success is the technology for the study of the subsoil. The goal of the initial stage of the oil cycle is to collect useful information to identify the best opportunities.
The discovery and classification of a new field is largely based on the analysis of three-dimensional images of the subsoil derived from a seismic study.
Geologists, engineers, physicists and mathematicians analyse seismic data – using the DVA platform, for example – to generate in-depth images of the subsoil.
One of Eni's proprietary technologies, DVA, analyses seismic data and returns a 3D image of the subsurface.
Here DVA technology allows us to understand the terrestrial and marine depths and facilitate the optimal positioning of drilling wells.
The development of cutting-edge technologies for the study of the subsoil is vital to the success of Eni in the discovery of new deposits. It is within the scope of successful platform exploration that we study sophisticated systems to render high-resolution 3D images of the structure of the subsoil – both in terrestrial and marine areas – on the basis of the data acquired.Learn more
Sound waves produced in the subsoil are reflected differently according to the various materials they encounter. By recording such reflections through "geophones" it is possible to construct detailed 3D images of the different geological formations and identify potential hydrocarbon deposits.
Today Eni produces oil and gas from turbidite reservoirs beneath the Adriatic Sea, in West Africa, the Gulf of Mexico, North Sea and Indonesia. Recent exploration activity offshore of Mozambique and Ghana are also based on the discovery of turbidite deposits. Everything has its origin in the phenomenon of gravitational flows. What are they? How do they form? And why is there such great interest in them?
