A study of abundance: major onshore and offshore oil and gas fields in Myanmar

As the demand for oil and gas soars, Myanmar has been trying to catch up by exploring new areas and taking a closer look at old fields. The government is also working together with foreign oil companies to increase production of both oil and gas. Here is an overview of the country’s major onshore and offshore oil and gas fields.
