Abstract
Methods and apparatuses for recovering heavy oil that, at least in one embodiment, include conditioning a reservoir of interest, then initially producing fluids and particulate solids such as sand to increase reservoir access. The initial production may generate high permeability channels or wormholes in the formation, which may be used for heavy oil production processes such as cold flow (CHOPS) or enhanced production processes such as SAGD, or VAPEX.
