Well tests at Norwest’s Lockyer Deep-1 complete

Norwest, Lockyer Deep-1 Gas Discovery Well

Norwest Energy’s Lockyer Deep-1 conventional gas discovery has officially undergone successful well testing operations with the six-day program confirming exceptional well delivery.

Well testing operations were completed during March 2022, discovering high levels of reservoir quality and high-quality gas composition across a 25 m interval of the Kingia Sandstone.

Likewise, a maximum sustained flow rate of 102 million standard cubic feet per day (MMscf/d) was achieved through a 76 to 64 inch choke, with a maximum instantaneous gas flow rate of 117 MMscf/d.

This is one of the highest rates ever recorded onshore Australia.

Subsequent analysis confirms that the testing objectives were met with an incredibly high-quality dataset recorded.

Some of the key insights from said analysis includes: absolute open flow rate for Lockyer Deep-1 estimated at around 190 MMscf/d, an estimated 70 billion cubic feet (Bcf) to 110 Bcf gas-in-place connected to the Lockyer Deep-1 well within the well test maximum radius of investigation AND high quality gas estimated to be 87.5 per cent methane and 3.9 per cent CO2.

Moreover, comprehensive analysis of all gathered geological evaluation data from the Lockyer Deep-1 drilling program has also been completed.

Notably, semi-qualitative rock typing of drilling cuttings indicates that additional gas pay may exist, over and over that which has already been identified via preliminary petrophysical analysis, with potentially effective reservoir down to 4085 m.

Additionally, average porosities within the Upper Kingia perforated interval are estimated to range between 13 and 21 per cent.

Moreover, having commenced ordering long lead items early in 2022 the joint venture (JV) is preparing for a drilling program across the broader Lockyer Deep/North Erregulla Deep structure, targeting commencement of a two well back-to-back program in the fourth quarter of 2022.

It’s worth noting that this commencement is subject to necessary land access agreements, regulatory approvals as well as rig availability.
