On 26 November 2019 Beach Energy Ltd reported that the Beharra Springs Deep 1 well, located in L 11, Canning Basin, flowed gas at 25 to 31 MMcfg/d on clean up indicating a high-quality reservoir. Production tests are now due to commence in early December 2019.   Lattice Energy Ltd, a wholly owned subsidiary of Beach Energy, spudded the Beharra Springs Deep gas exploration well in early October 2019. The well was drilled by the "EWG 106" land rig. On 28 October 2019 Beach Energy reported that it was completing wireline log operations, after reaching a total depth of 4,170 m. Initial results of the logging indicated a gas discovery within the Kingia Formation.    During drilling, a 65 m reservoir interval was intersected within the Kingia unit, between 3,935 and 4,000 m, with the operator reporting estimated net pay of 36 m. Wireline logging was undertaken across this unit which determined an average porosity of 14.5%. Preliminary interpretation suggested porosity could be up to 21%.    The well was targeting gas within the Kingia and High Cliff sandstones, with possible additional targets in the Dongara and Wagina units. It was targeting stacked gas pools, like those seen in the Waitsia field, discovered in September 2014. Waitsia was considered to be the largest onshore gas discovery in 50 years in the basin.    Beharra Springs Deep 1 spudded a little later than planned, being outlined for Q3 2019. The well was reported to be a drill ready prospect as of February 2018, with well planning then taking place in 2H 2018. Beharra Springs Deep 1 was originally planned to be spudded in 1H 2019, but this was revised part way through the year.    L 11, which covers an area of 75 sq km, was awarded on 15 May 1992. Participants in the permit are Lattice Energy Resources Pty Ltd (50% + Operator) and AWE (Beharra Springs) Pty Ltd, a Mitsui subsidiary, (50%). The companies hold this interest after an alignment agreement was entered into on 3 July 2019, which saw Beach and AWE agree to share 50:50 ownership of their shared assets in the basin, including L 11.
