Method and system for inhibiting contact of a corrosive displacement gas with corrosion prone natural gas production facilities |
摘要 |
<p>Natural gas production from an underground natural gas containing formation(20) is enhanced by initially injecting into the formation(20) a non-corrosive Nitrogen (N 2 ) containing displacement gas followed by injecting into the formation a corrosive CO 2 containing displacement gas such that the non corrosive displacement gas provides a barrier that inhibits the corrosive displacement gas to reach corrosion prone natural gas production facilities. Subsequent injection of non-corrosive and corrosive displacement gases reduces the cost of displacement gas injection, inhibits corrosion of natural gas production facilities, and reduces CO 2 emission into the atmosphere.</p> |
