Lakes Blue Energy NL (ASX:LKO) has confirmed that all specialist equipment required for the Wombat-5 workover, perforation and testing programme has arrived in Australia, with contractors and staff scheduled to mobilise to the Wombat site on 9 November 2026 and works expected to take three weeks to complete.

Key Points

  • All specialist equipment for the Wombat-5 programme has now arrived in Australia
  • Contractors and staff are to be mobilised to the Wombat site for 9 November 2026, with works commencing mid-November
  • The workover, perforation and testing programme is estimated to take three weeks to complete
  • The programme will reconfigure the well completion, perforate selected reservoir intervals and conduct flow testing to assess the well's performance

Wombat-5 Workover Programme Scope

The planned works at the Wombat-5 well are designed to reconfigure the well completion, perforate selected prospective reservoir intervals and conduct flow testing. The programme is intended to establish the gas flow response from those intervals and assess the well's performance. The Wombat Gas Field is 100%-owned by Lakes Blue Energy and is located in Victoria's onshore Gippsland Basin. Technical preparation has included modelling to assess penetration beyond near-wellbore damage and identification of the reservoir intervals to be targeted for perforation.

Technical Preparation and Fluid Studies Completed

Fluid-lifting modelling has assessed the ability of the planned 2⅜-inch tubing to effectively remove produced fluids from the well. Fluid compatibility testing has found no adverse clay swelling or fines mobilisation with the planned fluid, according to the filing. Sanding studies have also defined drawdown limits to guide flowback and reduce the risk of sand production and fines movement. The company said these technical preparation steps have been completed ahead of the scheduled mobilisation of contractors to the Wombat site.

Flow-Test Data to Inform Wombat Gas Field Evaluation

Following completion of the programme, flow-test data will be reviewed to assess gas deliverability and inform further evaluation of the Wombat Gas Field, the company disclosed. Chairman Hugh Robertson stated: "We are delighted to have final delivery of the required equipment and are looking forward to completing the testing this month. We remain optimistic as to the outcome of the testing and the development of the Wombat gas field." Lakes Blue Energy said it will provide further updates as the programme progresses and results become available. The filing was authorised by the Board of Lakes Blue Energy NL and dated 5 November 2026.
