Abstract
In this study, we performed reservoir simulations to investigate CO2 storage in the saline aquifer in Sleipner by reservoir pressure management. Results show that by producing water at the lowest aquifer structure far away from the CO2-water contact in the vertical direction, an additional 73% (24 Mt) CO2 can be stored compared to the case without water production. This extra CO2 stored can generate a revenue of $800 millions at the prevailing carbon tax of $69 per ton in Norway. There is 5.31 Mtpa of natural CO2 production from 124 gas and oil fields in Norway in 2020. Of these, the Marulk, Dvalin, Skarv, Morvin, Åsgard, Kristin, Tyrihans and Mikkel fields in the Norwegian Sea, and the Kvitebjørn, Valemon, Visund, Gudrun fields in the North Sea produce a total of 4.55 Mtpa CO2 potentially supplying CO2 to Sleipner for project life extension.
期刊介绍：
The objective of the Journal of Natural Gas Science & Engineering is to bridge the gap between the engineering and the science of natural gas by publishing explicitly written articles intelligible to scientists and engineers working in any field of natural gas science and engineering from the reservoir to the market.
An attempt is made in all issues to balance the subject matter and to appeal to a broad readership. The Journal of Natural Gas Science & Engineering covers the fields of natural gas exploration, production, processing and transmission in its broadest possible sense. Topics include: origin and accumulation of natural gas; natural gas geochemistry; gas-reservoir engineering; well logging, testing and evaluation; mathematical modelling; enhanced gas recovery; thermodynamics and phase behaviour, gas-reservoir modelling and simulation; natural gas production engineering; primary and enhanced production from unconventional gas resources, subsurface issues related to coalbed methane, tight gas, shale gas, and hydrate production, formation evaluation; exploration methods, multiphase flow and flow assurance issues, novel processing (e.g., subsea) techniques, raw gas transmission methods, gas processing/LNG technologies, sales gas transmission and storage. The Journal of Natural Gas Science & Engineering will also focus on economical, environmental, management and safety issues related to natural gas production, processing and transportation.
