Abstract
One of the major fields in the South of the Sultanate of Oman produces oil at 94% average BSW. All produced water is<br>disposed of without treatment into the same aquifer. The disposed water is injected under fracing conditions and takes place<br>more than 200 m below the lower shale (cap rock) in the sandstone (Fig.1). However the failure of the field’s cap rock could<br>result in oil deferment and the contamination of the overlying aquifer; therefore rigorous risk management is strongly<br>required.
