Oil field currently producing gross 650 bopd high quality (37 deg API) crude from four wells tied back to a centrally located production facility for simple separation and storage. Oil is trucked to an export terminal at Wyndham (1000km away), stored in tanks and exported by ship.

The production licenses include appraisal potential at the Ungani North discovery.

 First Production July 2015
 Geology The asset is located in the Fitzroy Trough of the onshore Canning Basin.  The main oil play is Carboniferous dolomite conventional reservoirs of the Lower Laurel Formation in fault and dip-closed structures, sealed by Laurel marine shales.  There is also hydrocarbon potential in the overlying Carboniferous to Early Permian clastic reservoirs.

On 21 May 2018, ROC agreed to buy a 50% interest in the Ungani production licenses from Buru. 

In 2H 2018, the JV drilled the Ungani 4 sidetrack production well and the Ungani West 1 near field exploration well.  Ungani Far West 1 water disposal well was converted to production.  Ungani 3 and Ungani West 1 are used for disposal of produced water.

In 2019, the JV drilled the Ungani 7H infill well, with two horizontal laterals.  A second horizontal infill well (Ungani 6H) was drilled to top reservoir and suspended.

In 2021 the JV commenced drilling the Ungani 8H infill well, with the objective of accessing additional reserves and extending the field life. Drilling operations were suspended in February 2022 after encountering geological difficulties in drilling the Ungani 8 well and subsequent side-track.
