	abstract = {Physical and chemical analysis of spent sand indicate that this material is very infertile. The spent sand samples analysed had an average pH of 7.2 and low Na content indicating that there was no residual problem resulting from the NaOH used in the oil production process. Freshly processed sand however does have a high pH and higher Na contents.},
