Murphy Australia WA-481-P Oil proposes to undertake drilling activities within the offshore petroleum exploration licence area  WA-481-P commencing during Q1 2015, in order to test for the presence of hydrocarbon resources.
Murphy has completed a seismic survey in the permit and now plans to drill up to 3 exploration wells. The wells will be drilled within Commonwealth waters in water depths between 50 m and 350 m. The minimum distances of the wells could be approximately 38 km from the Western Australian coast and approximately 25 km from the Abrolhos Islands.
The MODU is expected to be situated at each drilling location for two to three weeks per well commencing Q1 2015 at the earliest, with the total time on location dependent on weather conditions and operational efficiency. Active drilling takes place 24 hours per day, 7 days per week and is expected to last 12 days for each well. The entire Activity is expected to last a total of 70 days, including drilling time and transit between well locations.
The wells will be drilled using a semi-submersible MODU. Up to 3 support vessels will be utilised during the Activity and helicopters for personnel transfer. Water Based mud (WBM) will be utilised to drill the wells and well formation evaluation will occur during the Activity which may include any of the following: mud logging, wireline logging and vertical seismic profiling (VSP). Following final evaluation of the wells they will be plugged and abandoned.
