Abstract

The research sets about describing the different oil types in the South Sumatra Basin and relating the hydrocarbon to source rocks. Four different groups of oil have been identified; the character of the oils suggests both lacustrine and terrestrial input to the source rocks. Type 1 oils have marine/lacustrine influenced (low pristane/phytane), Type 2 are terrestrially derived (high pristane/phytane ratio), Type 3 are also lacustrine (oils with bimodal distribution of n-alkanes) and Type 4 are biodegraded oils. These oils are distributed randomly in the South Sumatra Basin and are believed to be sourced from the terrestrial TalangAkar and lacustrine Lemat/Lahat formations.

 

Key words: South Sumatra, lacustrine, terrestrial, pristane, phytane.
