Unlike solid minerals which are dividable between countries on the basis of borders, oil and gas resources are immigrabledue to their fluidity and by creating any way out from their reservoir. Accordingly, if each State in its boundaries, extracts oil and gas from joint fields, it can cause fluid movements of resources, especially gas, in all reservoir and can move all or significant portion of the existing reservoir of adjacent country toward its side. Based on international law, States are responsible for unfair extraction of joint fields and they cannot violate the ruling right of a neighbor State. Compensation for infringing of this right/duty, is both calculable and demandable. Based on extant evidence, Iran boundary and rights in joint field of Pars-e-Jonoobi has been violated and Qatar government is responsible for compensation due its violating the rights of Islamic Republic of Iran.
