iscal regime is one of the main differences between petroleum contracts. Fiscal regimes in oil contracts are divided to two main categories namely Concessionary and Contractual Systems. In contractual systems, the main difference between service and production sharing contracts is the way of compensation of contractor services which could be in cash or in kind. In production sharing contracts the contractor receives a portion of produced oil. One of the main criteria to compare fiscal regimes is government and contractor takes in real values. Comparing the net present value of contractor take shows that it could have been more desirable and cost effective to use production sharing contract in Iranian Azadegan oil field instead of Buy-Back.
