Beach Energy (Operations) Limited, a subsidiary of Australian oil and gas company Beach Energy, has handed over an environmental program (EP) involving drilling activities off the coast of Australia to the country's marine regulator.
The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) confirmed that Beach Energy recently submitted an environmental plan to conduct a drilling campaign within federal waters. Otway and base basin.
The scope of the proposed drilling program includes drilling up to six wells in the Otways, including drilling up to five exploration or appraisal wells under exploration licenses VIC/P73 and/or VIC/P43. and may include a combination of drilling up to two exploration wells. Exploration license T/30P well.
In addition, the drilling of up to five wells in the bus may be required, including the drilling and drilling of up to four appraisal wells under holding licenses T/RL2, T/RL4, and/or T/RL5; May include a combination of trials (conditional) to complete one infield well (Yolla 7) with production license T/L1.
Separately, five conventional suspended subsea exploration wells Thylacine 1 at T/L2, Geographe 1 at VIC/L23, Trefoil 1 at T/RL2, and Yolla 1 were blocked and abandoned in their well infrastructure above the mudline. , removal is also being carried out. White Ibis 1 of T/L1, T/RL4.
Under the EP, drilling and plug-and-abandon (P&A) activities are conducted within a 3 km radius around the well site while the drilling rig is moored at the site. The 3 km radius includes the outer extent of the seabed moorings and the 500 m Petroleum Safety Zone (PSZ).
According to Beach Energy, estimated timing for drilling activities is expected to be 30 to 40 days per well, with completion expected to take 15 to 20 days for one well (Yolla 7), and one for plug and disposal operations. It is estimated to take 15 to 20 days per well. . These activities he carries out 24 hours a day, 7 days a week.
Additionally, these timings represent approximately 560 days of activity for the entire drilling program, which is expected to occur from November 1, 2024 to December 31, 2028. The proposed offshore activities will be carried out on a single moored semi-submersible drilling rig. Thruster auxiliary mooring system. This rig is supported by up to three vessels.
This EP submission was submitted by Beach Energy. Otway Offshore Gas Victoria The project outlines tying hydrocarbon-producing wells to existing wells. Otway Gas Production Pipeline (OGPP) and/or existing Thylacin A A platform with new subsea flow lines and facilities installed.
