Method of consolidating an unconsolidated oil sand

Patent ·
OSTI ID:5538503
;
An unconsolidated sand is consolidated in an annulus adjacent a production well penetrating an oil stratum by depositing a slug of an autoignitable oil in the annulus. A stream of oxidant gas (air) is injected through an offset well and through the stratum to the annulus at a rate sufficient to ignite the oil. This leaves a coke residue in the annulus, and starts an inverse burning combustion zone in the stratum. (9 claims)
