Quadrant updates Belgravia prospect

In its December 2017 quarterly report, Woodside Energy as operator of Swell-1 announced that the well had intersected interpreted gas sands across a large gross interval of approximately 450 m.

Swell-1 was announced as a tight gas discovery, not currently commercially viable given the low gas mobility at the depth the Triassic was drilled, down to 5,006 m measured depth.

The Swell-1 result is encouraging for the WA-155-P equity holders as it has confirmed the presence of a working petroleum system as well as containing a large gas column that was on the high side of pre-drill expectations.

Equity holder Carnarvon Petroleum’s mapping indicates the crest of the Belgravia structure is updip of the Swell gas discovery and around 650 m shallower than the Swell-1 structure.

Typically, reservoir quality improves at shallower depths, which means Belgravia could expect to contain better quality compared to that reported at Swell-1.

However, further work is required to fully consider the outcomes and opportunities arising from the Swell-1 well result.

Equity holders in WA-155-P are Quadrant Energy (71.5 per cent and operator) and Carnarvon Petroleum (28.5 per cent).
