Experts at Research Institute of Petroleum Industry (RIPI), which is the main center of research and exploration for gas hydrates in Iran, say that each cubic meter of gas hydrate generates as much thermal value as 164 cubic meters of gas. Common technologies used for recovery from these resources may be costlier than technologies used for recovering from conventional resources; however, the cost-effectiveness of gas hydrate recovery becomes known when conventional resources go on the decline. Touraj Behrouz, head of Upstream Industry Research and Development Division of RIPI, has said good achievements have been made in modelling, studies and lab activities in both conventional and conventional fields.
