Preview Abstract
Low-temperature oxidation (LTO) of crude oil has been employed to
investigate its potential as a sand consolidation technique. Loose sand
(20/30 mesh) saturated with crude oil (18 - 20 API) and brine was subjected
to air injection at a low temperature (100 - 150 C) for a period of time (6 - 18
hours). The sand packs developed compressive strengths ranging between
375 and 1264 psi and suffered a maximum permeability loss of 22%.
It was found that higher oxidation temperatures reduced the consolidation
time and increased the compressive strength; but had no effect on the
magnitude of permeability loss. Heavier oils required less oxidation time,
caused slightly larger permeability losses, but had an insignificant effect on
compressive strength. The presence of clay enhanced the LTO reactions by
shortening the oxidation time and increasing the amount of residue
