Even with the extensive well log and core
database available on the Norwegian continental shelf together with long
production experience, predicting the occurrence and distribution of
hydrocarbon bearing sands within the fluvial-dominated Statfjord
Formation in the Tampen Spur area of the Norwegian
North Sea is still a very difficult task. Current recovery from the Statfjord Fm on the majority of the Tampen
fields is low and a contributing factor to this is an incomplete understanding
of facies types & distribution and the potential correlatability away from well data. The use of outcrop
analogues for studying the facies types, their
relationships and stratigraphic development together
with collecting geometrical and relational data for reservoir modelling input is a key tool for better understanding the
subsurface Statfjord Fm reservoirs. The fluviatile, Upper Jurassic (Kimmeridgian)
Lourinha Formation within the Lusitanian Basin of
Portugal contains over one thousand meters of stratigraphy
that is considered a good analogue for collecting such field data to assist in
understanding the Statfjord Fm and also providing
input data to reservoir modelling studies of the Tampen fields. This study is only in its infant stages but
already a large amount of sedimentological, stratigraphic, biostratigraphic
and geometrical data has been collected in the field and is in the process of
being analysed and implemented. This paper aims to
