AQUIFER-PLUGGING STEAM SOAK FOR LAYERED RESERVOIR |
摘要 |
<p>AQUIFER-PLUGGING STEAM SOAK FOR LAYERED RESERVOIR An improved steam soak process recovers viscous oil from a reservoir containing a relatively steam impermeable oil-rich layer above a relatively steam permeable water-rich layer. Steam is injected at a rate and volume that displaces an cil bank into the water layer. The cooling of the oil bank impedes the flow of water so that, during the production cycle, the rate of oil recovery is increased.</p> |
