The steam injected into the oil reservoir in the SAGD
process helps bitumen
flow in two ways – reducing its viscosity by heating it, and maintaining pressure in the reservoir to facilitate bitumen flow. MEG’s patented eMSAGP technology – enhanced Modified Steam and Gas Push1
– involves co-injecting a non-condensable gas, like natural gas, with the steam. Once there is sufficient heat in the reservoir, the non-condensable gas helps maintain pressure and frees up steam to be redeployed into new SAGD well pairs.
