formation
is it possible to achieve a stable production of
oil
from the deepest chalk stratum in the north sea, the
tuxen
formation
? this is the focus of dhrtc?s latest research programme ? tight reservoir development (trd). today, in certain
oil
fields the
oil
industry recovers
oil
from the deep chalk stratum, the
tuxen
formation
, which was formed more than 100 million years ago. the
tuxen
chalk is less permeable than the chalk in the ekofisk and tor
formation
s higher up, and it presents a challenge that the production varies so much from well to well. there are relatively large quantities of
oil
in the
tuxen
formation
at locations where the industry already has infrastructure in place. however, there is a need to clarify how best to develop production, and to clarify whether new investments in equipment would be worth- while. at the end of 2016, dhrtc decided to initiate the research programme tight reser- voir development, which focuses on finding out more about the deep chalk stratum. the programme will be described in more detail in demo models in 2017. from the outset, it is clear that it is necessary to conduct research into the core disciplines of geology and geo- physics, as knowledge about the
formation
is still incomplete. photo: finn jakobsen et al. 2003, geus
