The Oyong field was discovered in 2001 by the Oyong 1 exploration well.
In July 2003, a Gas Sales Agreement was reached with PT Indonesia Power for the entire gas reserves of the field. In April 2005, The Indonesian government approved a revised plan of development for early oil production allowing the JV to sanction the project and commence development. Gas production commenced from the Oyong Phase-2 project on 2 October 2009.
First oil production commenced 24 September 2007 and first gas commenced 2 October 2009.
The field has had an offshore wellhead platform installed with five oil and two gas production wells.
Phase 1: During phase 1 crude oil will be produced to the Sea Good 101 production barge for separation and re-injection of the associated gas into the reservoir. The processed crude oil will be piped to the Shanghai FSO for storage and offtake. Initial production rates are expected to ramp up to between 8,000 - 10,000 barrels of oil per day.
Phase 2: During Phase 2 gas will be transported via a dedicated 60 kilometre pipeline to an onshore gas processing facility adjacent to the Grati power station on East Java. Gas export rates are expected to be ~60 MMscf/d during the plateau period.
