Adnoc studying expansion of CSS
Abu Dhabi wants to free up gas for power generation
Abu Dhabi National Oil Co is studying a proposal to expand the injection of carbon dioxide into fields for enhanced oil recovery (EOR) an official from Adnoc unit Abu Dhabi Co for Onshore Oil Operations (Adco) said.
After a successful pilot project using 60 tons a day of carbon dioxide in the Rumaitha field, the company has identified larger areas of the field to inject 1,750 tons a day of CO2, Reuters quotes CO2 EOR Strategy Advisor Ghaniya Bin Dhaaer al Yafei.
“We have proposed it to Adnoc; it is being studied,” al Yafai said at the World Future Energy Summit in Abu Dhabi on Tuesday. “EOR is seen as a way of sustaining the plateau of production, and an opportunity to replace gas currently being used for pressure maintenance.”
Adco is looking at ways to reduce its use of as much as 40 percent of the 5 billion cubic feet of natural gas produced daily in the UAE so that the fuel can be used to meeting soaring power and industrial demand.
Capturing harmful greenhouse gas emissions is also part of the emirate’s strategy to become a leader in alternative energy, in collaboration with its renewable energy company Masdar.
Potential sources of CO2 for injection would be from Emirates Steel Industries PJSC, as well as the Habshan field, al Yafei said.
“It depends on the commercial aspects. We are still negotiating with Masdar on the delivery and timeline,” al Yafei said. “The leadership is very keen, and Adnoc will try to implement the aspirations of the leadership, unless it proves very much uneconomic.”
Gas is used for enhanced oil recovery, increasing pressure inside reservoirs to push more crude out.
