<p>A startup process for a Steam-Assisted Gravity Drainage (SAGD) operation may include pressure pulsing from within a horizontal section of one or both SADG wells, the pulsing source being within a startup fluid such that pressure pulses propagate into a treatment zone of the interwell region between the SAGD wells, thereby providing micro-fracturing and/or dilation in the treatment zone. The process may also include providing a penetration pressure on the startup fluid such that a portion of the startup fluid penetrates into the treatment zone to increase fluid mobility. The process may be implemented in shallow reservoirs, plastic reservoirs, and operations having a low maximum operating pressure (MOP) limit, for example.</p> |
