Woodside Energy Ltd proposes to drill an exploration well by either a semi-submersible drill rig/drillship that is moored or operates under DP, or a DP drillship, with associated support vessels.
Key activities are as follows:
Drilling of the top-hole sections using seawater with high viscosity sweeps
Installation and cementing of steel casing in the hole
Installation of the blow out preventer (BOP) on the wellhead and testing
Connection of marine riser between the BOP and the drill rig/drillship to provide a closed loop system for the recirculation of drilling fluids and drill cuttings from the well to the drill rig/drillship.
Drilling of bottom hole sections to the planned depth
Formation evaluation, may include cores, wireline logging and vertical seismic profiling (VSP) as required.
On completion plugging and abandonment of the well
The proposed activity area is located in permit area WA-271-P, Exmouth Sub-basin, Western Australia, offshore in Commonwealth waters, approximately 65 km north-west of Exmouth.
The proposed Petroleum Activities Program is scheduled to commence in Q2 2015 with the Malaguti well taking approximately 60 days. The schedule and timeframe may be subject to change due to operational requirements and external influences such as drill rig/drillship availability, weather conditions and oceanic conditions.
