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.
Single collector wells called “infill wells” are also placed in the sweet spot between producing SAGD well pairs to collect bitumen that would otherwise be unrecoverable, increasing efficiency.
eMSAGP is a proven process that has tranformed our business by reducing SOR, resulting in lower costs and greenhouse gas emissions per barrel of bitumen produced. To date, eMSAGP has been successfully deployed at a significant portion of MEG’s wells. The technology has enabled MEG to increase production without increasing steam generation capacity.
1 Steam and Gas Push (SAGP) was invented by the late Dr. Roger Butler, who also invented the SAGD process.
MEG is the leading pure play in situ thermal oil producer in Canada. MEG’s strategy is focused on delivering sustainable free cash flow by leveraging its high-quality assets and exceptional team.
