Research methodology in oil and gas law course

Oil and Gas Law Course is an interdisciplinary branch of law which has been recently, for the first time in the Middle East States, introduced and established in Tehran University. This Course deals with various aspects of law, including "private law" and "international investment law" while dealing with the NOC with IOC, relationship and "public Law" while dealing with the host government (HG) and IOC relationship. On the one hand, since this Course has an international nature and character, thus it should be looked upon and studied as practical and operational. On the other hand, since this Course is a multidisciplinary course, its research methodology should be different from an ordinary law course. In this article, four methods including "Abstract", "Allegory," "Procedural" and "Deductive" will be discussed and the advantages and disadvantages of each will be studied.
