NHDA holdings

The NHDA makes archive data available to the public at low cost. The medium- to long-term aim is that archived data will be made available online (if this is appropriate for the data type), when BGS develops its infrastructure for online access to data. However, at present data can only be supplied by the NHDA on appropriate modern media, or can be delivered by ftp or email. Archived post-stack seismic data and well data in the CDA DataStore can be accessed and downloaded online by CDA members. The CDA DataStore also provides post-stack seismic data to the public on behalf of the NHDA, offline.

Note that the DECC/NHDA Agreement contains some restrictions on the NHDA in the provision of certain categories of well data, and seismic section data, which are only available from DECC Data Release Agents rather than from the NHDA.

For well data, the NHDA cannot publish any logs or other Basic Set well data (as defined in PON9) for exploration and appraisal wells until twenty years after the well completion date. It can publish other reports that are not specified in PON9, and all data for archived development wells. Note however, there are no restrictions on CDA members downloading NHDA data from the CDA DataStore.

BG, BHP Billiton, BP, Chevron, CNR, RWE DEA, Shell and Total have archived wells and seismic surveys with the NHDA. Kerr McGee began archiving of the Hutton Field, and this process was completed by Maersk.

Information on the wells and the seismic surveys archived with the NHDA is posted on DEAL.
