Capture, Storage and Use of CO₂ (CCUS). Reservoir data - Stenlille area (Part of Work package 6)

Late 2019, GEUS was asked to lead research initiatives in 2020 related to technical barriers for Carbon Capture, Storage and Usage (CCUS) in Denmark and to contribute to establishment of a technical basis for opportunities for CCUS in Denmark. The task encompasses (1) the technical potential for the development of cost-effective CO2 capture technologies, (2) the potentials for both temporary and permanent storage of CO₂ in the Danish subsurface, (3) mapping of transport options between point sources and usage locations or storage sites, and (4) the CO₂ usage potentials, including business case for converting CO₂ to synthetic fuel production (PtX). The overall aim of the research is to contribute to the establishment of a Danish CCUS research centre and the basis for 1-2 large-scale demonstration plants in Denmark.

The present report forms part of Work package 6 and focuses on evaluation of reservoir data and reservoir subdivision. A comprehensive dataset exists from the Stenlille area, and this dataset has been used to predict and extrapolate reservoir parameters to the Havnsø structure. The overall objective is to examine the possibilities of CO₂ storage in sandstone reservoirs like the Stenlille Gassum Formation. Hence, the existing log and core analysis data acquired in the Stenlille wells have been evaluated, addressing the clay content, porosity, and permeability.
