Status |
Production currently suspended while public road infrastructure is repaired following ex Tropical Cyclone Ellie. Before shut in, oil field was producing gross 540 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. |

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. |

History |
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. Operations in 2022 focused on production optimisation. Due to the impact of ex-Tropical Cyclone Ellie on road infrastructure in the Kimberley, production at Ungani was suspended in the first week of 2023, with the forward production plan under assessment as the timing of repairs to the damaged infrastructure is quantified by Main Roads. |
