SUMMARY:PESA QLD: July Technical Evening - Constrained by Geology: Reducing Sub-Seismic Uncertainty with Depositional Analogues and Synthetic Data
DESCRIPTION:PESA QLD July Technical Evening\nConstrained by Geology: Reducing Sub-Seismic Uncertainty with Depositional Analogues and Synthetic Data\nPresented by: Dr. Boyan Vakarelov (Founder\, SEDBASE) \nAbstract:\nMany critical subsurface decisions depend on predicting fluid flow through stratigraphic architectures that occur below typical seismic resolution or in areas with sparse well control. This sub-seismic uncertainty can be meaningfully reduced through following a geology-first approach\, where depositional variability is constrained by process understanding and calibrated against natural analogues. Such an approach should embrace multiple geologically valid solutions and focus on the architectural scale most relevant to the decision at hand.\n\n\nThis presentation draws on insights from an extensive depositional analogue database compiled over the past two decades\, highlighting how process regime and system type control the architecture of shallow marine and fluvial successions. We will then demonstrate how forward stratigraphic and object-based modeling workflows can generate geologically realistic scenarios in data-limited settings. These models not only improve uncertainty quantification and ultimately flow prediction\, but also provide physics-informed synthetic datasets for training AI neural network models.\nEvent Details:\nDate: Thursday\, July 30th 2026 \nTime: 5 pm for a 6 pm start \nPlace: Transcontinental Hotel\, Brisbane \nStandard tickets close 5 pm Monday\, July 27th 2026. \nThose attending the July Core Workshop are welcomed to attend this technical evening with a reduced ticket price.

SUMMARY:PESA QLD: Technical Evening\, November 19: Henry W. Posamentier on 'Recent applications of seismic geomorphology/stratigraphy'
DESCRIPTION:PESA Queensland welcomes 2025 PESA Distinguished Lecturer\, Henry W. Posamentier to present a technical evening presentation on Recent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea. The technical evening will be held at the Transcontinental Hotel. \nDue to the significant crossover with our peer society ASEG (Australian Society of Exploration Geophysicists)\, ASEG members are welcomed to attend at PESA member pricing. \nSpeaker travel and accommodation has been supported by Santos Ltd. \n\n\n\nPresentation:\nRecent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea\n\n\nVenue:\nTranscontinental Hotel\, 482 George St\, Brisbane City QLD 4000\n\n\nDate & Time:\nWednesday\, 19 November 5:15 PM for 6:00 PM Start\n\n\n\n\n  \nRecent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea\nHenry W. Posamentier\nThis presentation will document the seismic stratigraphic and seismic geomorphologic expressions of deep-water deposits of the Bay of Bengal and the Norwegian Sea. They comprise both turbidites as well as mass transport deposits. The turbidite deposits from the Bay of Bengal include leveed channel complexes\, terminal fans\, and overbank sediment waves. With respect to terminal fans\, there are those that terminate basinward of leveed channel systems and are relatively large\, and those that are deposited late within a lowstand cycle of deposition and are confined between the levees of precursor larger channels\, and are relatively small. Intra-basinal channels (i.e.\, channels that start and end on the basin floor) are observed within abandoned meander loops as well as interchannel overbank terrains. These intra-basinal channels are characterized by low sinuosity and likely are mud-filled with no exploration potential.  \nMass transport deposits from the Norwegian Sea include flows\, slumps\, and slides\, as well as isolated outrunner blocks. These deposits are associated with significant substate erosion up to 250m. The outrunner blocks are observed in clusters\, generally in radiating patterns down-system. Some of the outrunner blocks at the termini of erosional furrows are associated with sediment tails orthogonal to the direction of transport\, indicating bottom current direction from southwest to northeast. In addition\, volcanic intrusive deposits will be documented. These intrusives comprise both dikes and sills. Some of the dikes are associated with laccoliths in the shallower section.   \n  \n\n  \nTickets for the Technical Evening Talk can be purchased below. \nEarly Bird ticket pricing will be available until Wednesday\, 12 November 5:30 PM – to avoid disappointment please register before this time. \n\n\n\n\nEarly Bird Ticket Price\nStandard Ticket Price\n\n\n\n\nMembers – $35\nNon-Members – $45\nStudent / Retired Members – $25\nMembers – $45\nNon-Members – $55\nStudent / Retired Members – $35\n\n\n\n\n  \nSpeaker travel and accommodation supported by Santos Ltd.
