Ph.d.-forsvar - Einar Madsen Storebø

Einar Madsen Storebø forsvarer sin ph.d.-afhandling “Effect of pyrite on fluid distribution and permeability modelling of North Sea Lower Cretaceous clay rich carbonate reservoirs”

Resumé (kun på engelsk):

Hydrocarbon exploration and production are still an important resource for meeting the ever-increasing energy need in the world and as we are depleting our already known and extensively studied reservoirs, the focus on the deeper more difficult to produce reservoirs gains limelight. This thesis provides practical methods for evaluating the hydrocarbon distribution and fluid flow in the clay rich carbonate reservoirs found in the Lower Cretaceous Sola and Tuxen formations in the Danish North Sea using well known physical relationships and methods.

This thesis presents models for fluid distribution and permeability evaluation along with accompanying parameters. These models are based on the use of conventional well logs and accompanying core material extracted when drilling the well Boje-2C in the Valdemar field. The reservoirs found in this well is, despite the high porosity, which is normally associated with high permeability, described as low permeable and hard to evaluate using standard methods.

The models provided can therefore be used as tools for exploring and production of these deeper and more difficult reservoirs, to obtain a better understanding of how they work, and how to produce the in place hydrocarbons.
