From data to information
EBN shares its knowledge of the Dutch subsurface, facilities and economics with interested stakeholders. Through its unique position as a participant in 200+ exploration and production licenses, we have access to a vast amount of data.
EBN uses the available data for special analysis, as for example the Geo-Drilling Events (GDE) database and the Hydrocarbon (HC) Show database. These databases are made freely available via a Spotfire-based webportal.

- Pressure SNS Database
- Geo-Drilling Events Database
- Hydrocarbon Show Database
- Petroleum System Analysis Database
Pressure SNS Database
A systematic visualization of the Pressure SNS Database constructed by TNO during a study of the pore-pressure and fluid dynamic systems in the Dutch Southern North Sea (SNS) basin. The database contains public data of several projects among which the “Integrated pressure information system for the onshore and offshore Netherlands” TKI study (TKIG01002). It consists of pressure and fluid dynamic data of ~1145 wells and can significantly improve the safe and responsible use of subsurface resources.
The database contains public well data, published on NLOG in, amongst others, well logs, well completion reports, formation integrity test/leak-off test reports, wireline formation test logs and production test reports. Further information on the TKI study and the database can be found in the Final report published on the NLOG website.

Geo-Drilling Events Database
The Geo-Drilling Events (GDE) database is freely accessible for operators active in the Dutch subsurface. It contains drilling event information from existing wells and provides a better understanding of GDEs and hazards in the Dutch subsurface. GDEs are those events for which a significant geological component contributed to the cause of the incident.
The information in the database can help to:
- Improve well safety and the reduction of non-productive time and well costs
- Provide a better understanding of geological drilling hazards in the Dutch subsurface
- Learn from past geological incidents by analyzing public data
Around 1100 GDEs in approximately 930 on- and offshore wells have been analyzed and QC’ed. More will be added over time.
Hydrocarbon Show Database
The Hydrocarbon (HC) Show Database provides a systematic overview of hydrocarbon shows encountered during the drilling and testing phase in the Dutch subsurface. It comprises integrated HC show information retrieved from mudlog data, well tests and core analysis. This information is compiled per stratigraphic interval in key wells drilled in the Dutch subsurface. The analysis uses a detailed classification scheme to describe all types of oil and gas shows and includes estimates for the confidence level of the interpretation.
The information in the database can be used to assist in exploration or in well planning, both for the E&P, as well as the geothermal industry. The database currently contains ~2200 wells of which approximately 700 on- and offshore wells have been analyzed in a detailed manner.
Petroleum System Analysis Database
To reduce exploration uncertainty a regional understanding of the petroleum system in the basin is important. To understand the regional variation in source rock maturity and hydrocarbon generation, EBN carried out a Petroleum System Analysis project of the entire Dutch offshore. The Petroleum System Analysis (PSA) project provides a high level overview of the distribution, quality and maturity of source rock intervals and their hydrocarbon generation capacity through time and space (IGI Ltd., 2019). The aim of the project is to better understand the regional variation in source rock maturity and hydrocarbon generation across the Dutch Offshore to reduce exploration uncertainty. This is achieved by creating an integrated geochemistry and basin modelling study utilising 1-D models of key wells and a grid based 3-D model calibrated to temperature and maturity data. The full report and database compiles all the results obtained by IGI Ltd., and includes a complete geochemical characterization and maturity and expulsion maps of the main source rocks. Note that the study had a regional approach and only public available data is used.
