In support of the 32nd Licence Round, the NSTA is releasing a rock physics study which has been conducted by Ikon Science. The study covers two parts of the UKCS – the Central North Sea (CNS) and the East Shetland Basin (ESB) and consists of the petrophysical and rock physics analysis of 45 wells and a seismic amplitude study of selected 3D seismic data sets. All of the deliverables from this project have been loaded to the Data Package tabs in the National Data Repository (NDR) and the user should download the data from there. The NSTA’s Well Data Availability layer has been updated to reflect which wells now have rock physics data available.  The exception to this delivery via the NDR are the seismic attributes that have been derived from 3D seismic volumes owned by PGS. To gain free access to these derived seismic volumes, users will need to have licensed the underlying multi-client data owned by PGS and to this end, will need to contact PGS directly. For the CNS area, this relates to surveys PGS17003 and PGS16008. For the ESB area this relates to surveys PGS EOK-2012 and PGS ESB-10. Any issues with accessing these attribute volumes should be sent to [email protected]
