carbon capture and storage

A major oil company is progressing a portfolio of commercial-scale carbon-capture-and-storage (CCS) demonstration projects covering an array of technologies that target applications of relevance to the wider oil and gas industry.

There remain a number of challenges with CO2 EOR. These include gravity override, poor sweep efficiency, and economic factors.

In chemical-looping combustion (CLC), oxygen is transferred from an air reactor to a fuel reactor by means of a solid oxygen carrier.

The deployment of appropriate CO2-separation technologies for natural gas processing is viewed as an abatement measure toward global CO2-emissions reduction. Selection of the optimum technology requires special attentiion.

The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR.

“Change” was the theme of Offshore Northern Seas (ONS) 2014 in Stavanger, Norway, in August. While commemorating the conference’s 40th anniversary, speakers called for changes in “business as usual.”

This paper describes the first successful attempt on the continental shelf offshore UK to map carbon dioxide (CO2) in real time while logging during a drilling campaign in the East Irish Sea.

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.

Research-and-development modeling has shown that CO2 can diffuse a small distance into the thick shale caprocks above brine aquifers used for sequestration and cause migration of siderite (iron carbonate), magnesite (magnesium carbonate), calcite, and other precipitates back into the target zone.

Several geological settings are appropriate for geological storage of carbon dioxide (CO2), including depleted oil and gas reservoirs, deep brine-saturated formations, CO2-flood enhanced-oil-recovery (EOR) operations, and enhanced coalbed-methane recovery.
