Thanks to investment and exploration for 30 years, Indonesia can enjoy the natural gas reserves that have not been used in a very large amount. The second largest natural gas reserves located in Arun, North Sumatra, and Borneo rhino in the East. Natural gas reserves in the base year (2011), is equal to 152.89 tscftrillion standard cubic feet consisting of proven reserves and potential reserves at 104.71 TSCF and 48.18 tscf (Natural Gas Statistics, 2012). Largest gas reserves are located in the Natuna (51.46 ) and Papua (23.91 tscf ) tscf (Figure 4). Indonesia contains large reserves of natural gas. Currently, the country contains the third-largest gas reserves of the Asia Pacific region (after Australia and China), accounting for 1.5 percent of total global gas reserves (BP Statistical Review of World Energy 2015). One of the major natural gas reserves in Indonesia is found in the Natuna D Alpha gas field. This is not only a large gas deposit (222 TCF), but is also interesting because it is composed predominantly of CO2 (71%). The last development scheme proposed by the oil companies Exxon and Pertamina for the utilisation of this gas, before the crisis Natural gas discoveries may provide a way to relieve US dependence on OPEC oil. An exploration surge raised reserve estimations after new government policies relaxed market regulations and began a Indonesia's oil and gas sector Indonesia had a proven amount of oil reserves of approximately 2.5 billion barrels in 2019, while only producing approximately 0.3 billion billion barrels of crude of medium-size fields were made by Caltex and some General overview over the growth of national gas other companies (Figure 5). reserves, as represented by the Proved reserves in The relatively good trend shown by the growth Figure 4, shows a promising situation indicated by of national gas reserves can further be underlined 26 INDONESIA'S Indonesia - Proved reserves of natural gas. 49.74 (trillion cubic feet) in 2021. In 2021, reserves of natural gas for Indonesia was 49.74 trillion cubic feet. Reserves of natural gas of Indonesia fell gradually from 92.5 trillion cubic feet in 2002 to 49.74 trillion cubic feet in 2021. Indonesia holds 98 trillion cubic feet (Tcf) of proven gas reserves as of 2017, ranking 13th in the world and accounting for about 1% of the world's total natural gas reserves of 6,923 Tcf. Indonesia has proven reserves equivalent to 65.6 times its annual consumption . With the third highest reserves of natural gas in Asia Pacific after China, the third highest coal production in the world and oil production that averaged 692,000 barrels per day (B/D) in 2020, Indonesia relies heavily on its domestic fossil fuel reserves for its energy. Its LNG export market share is the second largest in Asia Pacific. oSypK.
