Netherlands Geochemical Database
The database comprises data for over 6889 samples from 764 wells, including over 1410 oil and gas samples and 5464 rock analyses, TOC content is reported for 4412 samples with almost all of these also having additional pyrolysis data; the isotopic composition of 155 samples are reported and maturity data in the form of vitrinite reflectance values are present for 1540 samples.
Geochemical data for wells drilled in the onshore Netherlands and the Dutch sector of the North Sea are available for download from the NLOG website, and have been used to compile this database.
The Netherlands Geochemical Database comprises 6889 samples from 764 wells drilled between 50.9°N and 55.5°N. These data include 5464 rock samples, 1410 oils and gases and 15 mud gas samples. TOC content is reported for 4412 samples with almost all of these also having additional pyrolysis data. Maturity data in the form of vitrinite reflectance values are present for 1540 samples. Gas compositions are available for ~1400 samples, with isotopes for 155 of these, and gasoline compositions are also available for many of the fluid samples. There are no biomarker or bulk fraction carbon isotope data.
The Netherlands Geochemical Database is provided with a Well Manager file containing available lithostratigraphy and basic well information for all wells (which have also been compiled into the database for samples with geochemical data). This allows the user to seamlessly add samples from proprietary or in-house sources to the database, and assign uniform stratigraphy, map coordinates and other well information. The dynamic database automatically updates all plots on sample addition to minimise reaction time between data acquisition and interpretation.
