Since 1998 e-GEOS has provided ENI Spa with a monitoring service for platforms (mainly located in the Adriatic Sea and the Ionian Sea) and onshore sites in Italy using space geodesy techniques based on GPS. The aim of the service is to estimate the three-dimensional displacement (vectors along the North, East and Up directions) of each site in order to evaluate the horizontal movement and the vertical displacement with millimeter level of accuracy through a differential data analysis approach.

Platform Monitoring
Since 1998 e-GEOS has provided ENI S.p.A. with a monitoring service for platforms (mainly
located in the Adriatic Sea and the Ionian Sea) and onshore sites in Italy using space geodesy
techniques based on GPS. The aim of the service is to estimate the three-dimensional
displacement (vectors along the North, East and Up directions) of each site in order to
evaluate the horizontal movement and the vertical displacement with millimeter level of
accuracy through a differential data analysis approach.
The monitoring is based on continuously acquired data by double frequency GPS receivers
(Continuous-GPS) installed on remote offshore/onshore sites and transmitted (via GSM,
Internet, Satellite) to the e-GEOS GPS Control Centre in Rome. At present the network
consists of 70 sites.
All the primary control segment functions are performed by the GPS Control Centre through
continuously upgraded technological platforms. The Centre evaluates the health and
integrity of the GPS stations and performs maintenance and anomaly resolution, collects
range/carrier measurements and navigation data and guarantees data archiving and backup. The GPS
Control Centre offers a state-of-the-art data processing and analysis facility, performing GPS real-time
data quality check, data processing with scientific software, advanced time series analysis according
to the specific customer requirements and delivery of the final products on a dedicated WEB Server.
Under the input of ENI E&P Division and in
cooperation with University of Rome, advanced
GPS Time Series Analysis and Research &
Development activities for improving GPS data
interpretation are on-going, such as spectral
analysis, time series filtering and detection of
velocity changes.

e-GEOS also participates in all the major European
R&D and pre-operational programmes, such as
Copernicus (formerly GMES – Global Monitoring for
Environment and Security) and leading the projects
MARISS (Maritime Security Services, an ESA-GMES
Service Element) and Dolphin (Development of Pre-
operational Services for Highly Innovative Maritime
Surveillance Capabilities – an EU-funded project),
and providing the European Maritime Safety Agency
(EMSA) with Oil Spill and Vessel Detection Services as
part of the CleanSeaNet public service.

Oil Spill Products
The operational use of satellite data in maritime applications allows the monitoring of sea waters
worldwide. In particular radar satellites are able to provide information on oil spills independently on
the day time and weather conditions (cloud/fog).
The detection of oil pollution at sea through satellites has been an effective operational European
service since 2007 in the hands of the European Maritime Safety Agency (EMSA).
Oil damps down capillary waves on the sea surface. SAR sensors detect oil slicks as areas of lower back-
scattered signal. The principal information reported within the Oil Spill Products are: a map showing
detected oil spill locations, their classification (low or high detection confidence) and characteristics
(width, length, surface).
Applications of oil slick detection encompass disasters (vessel/rig accidents), illegal activities (tank
washing) and oil exploration (natural seepage), accidental leaks.
In particular, the COSMO-SkyMed constellation supports large
scale monitoring for oil spills with its ScanSAR observing mode.
The minimum 4 times/day revisit time supports operational
use of a SAR-based oil spill monitoring service.
H24 Emergency Service Capability
e-GEOS is currently able to provide the best solution for
emergency response due to:
• complete control and world-wide commercialisation of the
Satellite Radar constellation COSMO-SkyMed giving a daily revisit time even at equatorial latitudes
• an emergency team available 24/7 to task, process and analyse data in near-real time in a multi-mission
approach
• procedures validated through more than 50 international events over the last 2 years
• a WEB-GIS delivery platform to disseminate information to Customer’s Control Headquarters and to
the areas where the emergency is ongoing
• proprietary systems to detect vessels and to extract oil spill and wind and wave information from
detected images in a format ready to be ingested by simulation models
• support to recovery activities with transmission of vector files and oil spill drift simulations to
response vessels and/or onshore teams
Given the above, the capability to efficiently respond in case of emergency is also tied to other
components of the responding systems:
• efficient and tested activation procedures between the satellite data/service providers and the oil &
gas operators
• tasking time of the satellites
• location of ground segment reception facilities
e-GEOS: #1 in Maritime Emergency
e-GEOS was ranked as the #1 service provider of the European Maritime Safety Agency (EMSA) during
the renewal of EMSA CleanSeaNet service in 2011.
e-GEOS has also been selected as the sole provider of the European Union’s Emergency Response
Service (ERS) in 2012, and for the next 3 years, providing data and maps for emergency management.

Off-Shore Oil Seep Mapping and
Analysis
e-GEOS provides Oil&Gas companies with Natural
Oil Seepage analysis and monitoring services on
specified Customers’areas of interest.
Natural oil seepage from the ocean floor can be
detected by satellite. Crude oil seeps naturally
go out of fissures in the ocean seabed, eroding
sedimentary rock.
The key point in identifying natural seepages is to
detect repeating leakages having similar features
in time. A repeated monitoring approach is then
necessary to identify emission points.
Natural seepage detection criteria:
• double/triple signature, due to multiple emissions
at short time intervals
• hook/like shape, due to the sea current transport
• multiple occurrence in time, due to emissions in
