CO2

This paper discusses novel technologies for increasing the energy efficiency of offshore oil and gas platforms. Three case studies are in progress that are based on actual oil-producing platforms—two on the Norwegian Continental Shelf (NCS) and one in the Brazilian basin.

ExxonMobil is testing its Controlled Freeze Zone technology, a single-step cryogenic process that allows carbon dioxide (CO2) to freeze in a controlled method and then melts the CO2. After recovery of the methane, the CO2 can be sequestered or used for EOR.

Through a range of experiments the authors demonstrate that small amount of H2S can be beneficial in reducing corrosion in 3% Cr steel.

Neeraj Gupta of the Battelle Memorial Institute and Nigel Jenvey of Maersk Oil and Gas comment on technology applications for carbon emission control and enhanced oil recovery.

This article focuses on the different scenarios for world energy demand and supply, along with their implications on energy-related CO2 emissions.
