Carnarvon Petroleum Limited announced provide an update on the Belgravia prospect within its Outtrim project in WA-155-P. The Belgravia prospect lies within the north westerly graticular block of the WA-155-P permit, adjacent to the Swell-1 exploration well. The company announced that the well had intersected interpreted gas sands across a large gross interval of approximately 450 metres. The Swell-1 well was announced as a tight gas discovery, not currently commercially viable given the low gas mobility at the depth the Triassic was drilled, namely down to 5,006 metres measured depth. The Swell-1 well result is encouraging in that it has confirmed the presence of a working petroleum system and contained a large gas column that was on the high side of Carnarvon geologist's pre-drill expectations. Carnarvon's mapping indicates the crest of the Belgravia structure is updip of the Swell gas discovery and around 650 metres shallower than the Swell-1 structure. Typically, reservoir quality improves at shallower depths. Accordingly, on face value, Belgravia could expect to contain better reservoir quality compared to that reported at Swell. However, further work is required to fully consider the outcomes and opportunities arising from the Swell-1 well result, particularly in regards to the consequences for the Belgravia prospect.
