Beach Energy (BPT) is free carried in a JV with Santos on the Beanbush field

In BPT's 31st March Quarterly they mention:

Drilling results
Beach participated in 14 wells, with two wells drilling ahead at quarter-end. An overall success rate of 92% was achieved (wells cased and suspended or completed as future producers). Drilling activity included successful gas appraisal drilling in the Meranji, Pelican and Kappa fields, gas development drilling in the Moomba and Tirrawarra fields and testing of deep coals in the Beanbush field (per the Santos farm-in commitment; Beach 100% free carried).

Further below there's a table where they list all the wells they've targeted and their current status and BPT ownership %.

Note: Drilling success is defined as wells cased and suspended or completed as a future producer or water injector.

Beanbush 3 ST3 is listed there as a successful well that's cased and suspended as they move on to appraisal as indicated in the more recent STO quarterly

Upon further confirmation of success this will open up the doors for further potential in the cooper basin.

BAS owns interest in eight Cooper Basin tenements, representing one of the largest holdings in the area.

Here is an old article and research report on the cooper basin deep coal potential: https://www.tandfonline.com/doi/pdf/10.1071/ASEG2018abM3_1A
They state from 2016-2017 deep coal has been accepted as viable gas target with those new methods mentioned. And this is what Santos is currently doing on Beanbush (successfully).

It appears that Santos was trialing / testing this deep coal potential and are now happy with the results to begin commercialisation efforts and appraisal
