There are no full-scale operating CO2 transport and injection projects in South-East Asia in which CO2 is extracted from a natural gas development and the CO2 subsequently stored or used for enhanced oil or gas recovery. However, there are several significant existing or planned gas-field CO2 storage projects elsewhere in the world. The main features of these projects are summarised below and described in more detail in the body of this report.
Main features of existing or planned gas-field CO2 injection and storage projects worldwide
|Project||Sleipner||Snøhvit||In Salah||Weyburn-Midale (CO2 EOR) (*)||Gorgon|
|Basin||North Sea||Hammerfest||Ahnet-Timimoun||Williston||Barrow Sub-Basin|
|CO2 injection rate in Mt/yr||1||0.7||1||2.8||2.7 to 3.2|
|Number and type of wells||1 × 1,250 m perforated horizontal||1 vertical||3 × 1,000 m perforated horizontal||650 production & 289 injection (Weyburn only)||9 vertical|
(*) Included for comparison; not a natural gas development project
The existence of these projects demonstrates in general terms the technical viability of CO2 injection and storage associated with gas field developments.
