The Petroleum Studies Department (PSD) is responsible for the continuous monitoring and analysis of short-term oil and product market developments. The department assesses the world oil market situation and makes its findings available to the OPEC Governing Bodies, including the OPEC Conference, as well as to the Member Countries.

Additionally, the department produces the OPEC Monthly Oil Market Report (MOMR), the Organization's flagship publication covering short-term oil market developments, which serves as a highly-regarded platform for dissiminating OPEC's views on market developments to the industry, market analysts and the general public. The MOMR is regularly reported in major media outlets and specialized energy industry publications.
