Horizontal heated plane process

摘要: A process for in situ recovery of a tar sand deposit located beneath the earth's surface. number boreholes are drilled laterally from subsurface tunnels into lower portion sands formation. Initially as displacing means such steam is injected boreholes, become viscous and gravity flow bottom boreholes. Continuing to apply removes deposits interstitial crevices between thereby allowing through these nearby The rises toward upper resource formation create horizontal heated plane further remove therein.
