Oil consumption, which has tended to increase, coupled with declining production, has resulted in Indonesia experiencing an oil deficit since 2003. BP data shows that Indonesia's oil production in 2003 was 1.18 million barrels per day, while consumption reached 1.23 million barrels. This means a deficit of 54,000 barrels per day.
Since then, national oil production has continued to decline while consumption has increased. Indonesia's oil production in 2017 was only 949,000 barrels per day, while consumption increased to 1.65 million barrels, requiring 702,000 barrels per day to meet domestic oil needs. Pertamina imports oil from abroad every year to cover this deficit.
This situation has led to a deficit in the national oil and gas trade balance. For information, the oil and gas trade balance in 2017 was a deficit of US$8.57 billion and increased to US$12.4 billion, equivalent to Rp 174 trillion at an exchange rate of Rp 14,000 per US dollar.
