Miscible displacement of petroleum
Patent
·
OSTI ID:5213084
A miscible displacement process for the recovery of petroleum from a petroleum-bearing reservoir is performed in situ by use of a solvent miscible with the petroleum and having a density greater than water. The solvent is introduced in the vapor state into the reservoir or is vaporized within the reservoir by a heated driving fluid and proceeds in a substantially horizontal manner through the reservoir forming a condensation front ahead of the driving fluid. The miscible front is followed by an aqueous driving fluid. The miscible solvent is carbon disulfide. (9 claims)
