Barents Sea: Jurassic and Triassic Reservoir Quality Database

RPS was appointed to devise, carry out and report the sedimentological and petrographical findings of various wells drilled in the Barents Sea, Norway.

Facies association data was synthesised into palaeogeographical maps, constrained by biostratigraphic data. Depositional modelling followed on from the sedimentological analysis of cores to better understand the sedimentary processes operating at various stratigraphical horizons. Petrographic analysis followed in order to investigate controls on reservoir quality from both a primary (depositional) and secondary (diagenetic) perspective. These data were summarised into a report and all data was made available digitally to the client companies.

Challenge

At the time of the initiation of the study in October 2006, there was no singly available report covering the sedimentological and petrographical analysis of the cored Jurassic – Triassic section in the Barents Sea. Various clients had drilled various wells but there was not a single report covering all the well data until this multi-client study was carried out.

Solution

RPS carried out the study in order to provide multiple clients a single database of the Jurassic – Triassic cored sections in the Barents Sea. These clients went on to use these data to aid them in further exploration in the Barents Sea, of which there has been a high level of interest, wells drilled and oil & gas discoveries made over the last few years.
