Andrew Pitchford, GM Subsurface and Phil Woods, Senior Geophysicist from Western Gas presented their latest findings of the Sasanof Prospect in block WA-519-P, to a sell out crowd at The George in the CBD. The Mentorc Gas discovery by HESS Australia (now Western Gas) opened up the Barrow Delta Topset stratigraphic play to more exploration in the Northern Carnarvon Basin. Mentorc, up to 30% porosity and 12 Darcy permeability, is fill to spill and Sasanof may be where all the spilling gas is...

PESA SA/NT Geology of Wine Field Trip – September 2019
By Dr. Simon Brealey
As is becoming traditional, stalwart devotees of the terroir of the McLaren Vale Wine Region (yes, it’s a bona fide appellation) gathered under a darkening sky in late September to receive the wisdom and tasting notes of Professor Alan Collins of Adelaide University.
Picking up stragglers as we headed south on the 40-minute drive we examined the beautifully-produced geological maps kindly...
PESA WA, August Technical Lunch

The presentation showcased the critical importance of high quality field work in understanding depositional processes and environments of coastal to shallow marine sandstone bodies in the Cenomanian/Turonian succession of Utah and Wyoming. The talk included details on the mapping and interpretation of Frontier deltas across a 70km by 5km section in the Vernal area of...
PESA WA Branch Winter Warmer 2019
It’s that blessed time of year when the PESA Winter Warmer provides respite from the weather’s

turnout of over 80 souls enjoyed the delicious lip-smacking food platters and beverage selection.
Conversations were long and florid and went on for many...
PESA WA May Evening Talk – Laurence Letki
Laurence Letki’s presentation highlighted wave-equation based techniques, such as full waveform inversion (FWI), as an integral addition to the modeling toolbox. The talk demonstrated how modern computing power allows the use of high frequencies in FWI and the resultant resolution of finer details.
The presentation was held at “The George” on Tuesday 21st May. Many thanks to Discover Geoscience, our evening talk sponsor.
PESA WA May Branch Luncheon
“If you’ve got an unconventionals focused geologist in your company, go talk to them, you might be surprised at the learnings applicable to conventional hydrocarbon accumulations”.
That was the takeaway from Avon McIntyre’s WA Branch May luncheon talk - “Bursting Source Rock and Strange Hydrocarbon Occurrences Around the World”. The presentation challenged attendees' thoughts on maturation, migration and charge-timing (all may be later than we think) through analysis of...
