ABSTRACT: Results and Experiences from the First Industrial-scale Underground CO2 Sequestration Case (Sleipner Field
,
North
Sea
)
CO2 separated from natural gas produced at the Sleipner field
in the northern
North
Sea
(Norwegian
block 15/9) is currently being injected into a saline aquifer, some 800 to 1000 m beneath the northern
North
Sea
. Injection started in 1996 and shall last for 20 years at annual rates of approx. 1 million
metric tons CO2 (for a description of the injection facilities and of basic reservoir data refer to Baklid
et al. 1996). An international research project, the Saline Aquifer CO2
Storage (SACS) project,
accompanies the ongoing injection. Its aims are (a) to determine the local and regional storage
properties of the reservoir (the Utsira Sand) and its overlying seal, and to assess their suitability for
CO2 injection elsewhere; (b) to monitor the injected CO2 by geophysical methods; (c) to simulate and
predict the present and future CO2 distribution by reservoir modelling; and (d) to develop a ‘bestpractice’
handbook to guide future CO2 injection projects. We report here results from areas (a) to (c).
