Recent work in many CSG pilots in Eastern Australia has shown that horizontal drilling can dramatically improve reservoir drawdown and accelerate gas production in lower permeability pilots. That, combined with large reductions in rig rates and improved steering technology, means this technology is a perfect fit to the Glenaras pilot project.

Two existing vertical wells will be utilised for the lateral with the kick-off lateral exiting from the Glenaras 5 wellbore and intersecting Glenaras 3.


Modelling of a 350 m lateral in this R1 coal shows gas flows within three months.

A total of 400 m of lower R1 coal has now been opened for production in the horizontal well and will be drawn down from the Glenaras 3 vertical well.

During the horizontal drilling operation, excellent pressure responses were seen at the central Glenaras4 well (located approximately 40 m from the horizontal well), confirming excellent directional permeability in this coal and exceeding the Company’s expectations.

- Lateral well a resounding success
- Flow rate significantly better than the existing vertical well performance
- In the coming months it is expected to initiate the onset of gas production

The Company is pleased to announce that production rates from the recently drilled lateral well are exceeding expectation. The lateral well is already flowing at over 2.5 times the rate of the previous 5-well vertical pilot at 50% drawdown. At full drawdown, the expected water rates from the lateral represent a 5-6-fold improvement over the best vertical well production rate previously recorded. This performance is above modelled expectations and is very exciting for the development of the Glenaras Gas project given the R1 coal at Glenaras is one of the lowest permeability coals in the permit. The aim of this lateral well was to accelerate drawdown of the R1 coal to initiate faster desorption and the onset of gas production. With the current rates the well is flowing, the lateral should achieve its objectives.

In its short production life we are already seeing excellent communication with the surrounding vertical wells, with the Glenaras 4 vertical well seeing a steady drop in bottom hole pressure tracking along with the drawdown of the lateral well. This confirms the excellent connectivity of the cleat system within the coals and confirms that the production is being sourced from the coal and not from neighbouring sandstones.


And now we're basically here, with the current (3x) multi-lateral pilot well program.
