Abstract
The oil and gas industry generates huge quantities of petroleum drill cuttings
(PDC) while exploring for hydrocarbon resources. These wastes are usually
contaminated; for this reason, environmental legislation prohibits their disposal
without treatment. The mining industry similarly exploits the earth for valuable
minerals and creates cavities in the process. These cavities are currently
supported and filled with cement paste backfill, (CPB) made from mine tailings
during and after mining activities. The increasing cost of mining operations
arising from the cost of CPB and the need to effectively dispose of treated PDC
suggests a possible industrial synergy could be achieved between the two
industries; utilising the waste of one (PDC from oil exploration) in the
production chain of the other (CPB for mine backfill). This work investigated
the potential for use of PDC treated by thermal desorption as a mine backfill
material. Extensive literature analysis was done on the various methods available
for treatment of PDC. Various potential and current utilisations of PDC and their
environmental impacts were also discussed. The research outcome showed the
possibility of use of thermally treated PDC waste as mine backfill material for
general fill (Post operations) rather than ground support or free-standing fill
applications.
