[4] In 1957, Royal Dutch/Shell's assets in Indonesia (trading as Bataafse Petroleum Maatschappij) were nationalised, from which Permina was founded as a state-owned oil monopoly, headed by Lieutenant-General Ibnu Sutowo.

[5] Sutowo's position as the second deputy of Abdul Haris Nasution was the beginning of the armed forces' involvement in the oil industry.

Permina founded the Apprentice Technical School (Sekolah Kader Teknik) in Brandan to train and produce experts in the field.

In 1960, the Provisional People's Consultative Assembly adopted a policy that oil and gas extraction could only be carried out by the state, through a state-administered company.

An agreement between the state and foreign companies was affirmed that gradually, oil refinery manufactures and other assets in marketing and distribution were to be sold to Indonesia within five to fifteen years.

In 1968, to consolidate the oil and gas industry for its management, exploration, marketing and distribution, Permina and Pertamin merged and became PN.

The 1974 oil price increases produced revenues of USD 4.2 billion in that year, equivalent to approximately one-sixth of Indonesia's gross domestic product.
