Abstract
Call-Out Service Contracts are widely used in oil and gas drilling projects to provide rapid and flexible access to specialized services under technical, operational, and temporal uncertainty. Despite their widespread use, their legal nature and binding effects, particularly under Iranian law, have received limited systematic analysis. This study examines whether such contracts create binding obligations upon conclusion or whether obligations arise only upon issuance of a Call-Out Order. Using a descriptive-analytical methodology with a comparative approach, the study primarily examines Iranian law, with reference to English and U.S. law where appropriate. The findings indicate that where the parties have agreed on the essential elements of their relationship and established mechanisms for determining variable obligations, a Call-Out Service Contract should generally be regarded as a binding framework agreement. It may therefore create obligations of readiness, availability, responsiveness, and compliance with contractual requirements before a specific Call-Out Order is issued, while particular service and payment obligations may be activated by such an order. The uncertainty of the timing, quantity, or frequency of future services does not, by itself, invalidate the contract where adequate determination mechanisms exist. The study further considers the implications of this characterization for contractual chains, payment mechanisms, liability, delay, back-to-back arrangements.
