There are two conventional disposal options for associated gas:
•Flaring: The unwanted gas is burnt off into the atmosphere. Flaring represents a massive resource waste and is also a considerable environmental problem, representing some 400 million tons of annual CO2 emissions.

•Reinjection: The gas is re-injected into the reservoir. Gas is often re-injected with the intention of preserving adequate reservoir pressure to ensure sustained, or sometimes increased, oil production. Where there is excess gas, however, “forced” reinjection can occur where there is no other option for disposing of the gas. In many situations, re-injection for gas disposal may not be technically feasible and can also complicate reservoir management, in the worst-case carrying risks of damaging reservoir performance.

•Market analysis reveals over 800 oilfields globally, onshore and offshore, where associated gas is problematic and conditions suit a modular GTL solution. There is an estimated total of over 73Bn bbls of crude reserves across these assets.
