Geodynamics completes first open flow test at the Habanero 4 well at its EGS project in Australia, achieving the planned maximum production rate of 35 kg/s before completion of the test.

Geodynamics Limited (ASX: GDY) is pleased to announce that the first open flow test for Habanero 4 has now been conducted. The staged open flow test achieved the planned maximum production rate of 35kg/s at a flowing pressure of 29 MPa (4,200 psi) through a variable choke, before the test was completed.

The surface pressures indicate the well has additional capacity to flow at higher rates which were not attempted during this test. Temperature at 4,130 m cable depth was recorded at 241°C with a surface temperature of 191°C, and increasing, after 82 minutes of flow.

Mr Geoff Ward, Managing Director and Chief Executive Officer of Geodynamics, said, “This is the highest productivity result achieved at the Habanero location and confirms our view of the quality of the Habanero 4 well. The results exceed
those achieved at Habanero 3 which recorded a stabilised flow of 27kg/s after local stimulation and again confirms the high productivity and temperature of the Habanero resource positioning Geodynamics well for a successful trial of 1MWe
Habanero Pilot Plant trial in the first half of next year.”

Local stimulation is now planned followed by a second open flow trial. Following the completion of the second open flow test, the planned major stimulation exercise will be commenced and is anticipated to be completed in early December. The Company will update the market as the testing and stimulation program progresses.
