The 2019 Myrtleville/Punchbowl Gully 2D Land Seismic Survey was acquired in late-October and early-November 2019 within the Denison Trough sub-basin of the greater Bowen Basin in southeast Queensland, Australia. The 2D survey was vibroseis sourced and consisted of four (4) seismic lines totaling twenty (21) line kilometres of data recorded across the Myrtleville and Punchbowl Gully gas fields within Denison Gas operated permits PL 43 and PL 183 respectively.

The seismic program was designed to provide infill structural and stratigraphic control thereby reducing the geological risk of possible future development, appraisal or exploration drilling opportunities in or near the Myrtleville and Punchbowl Gully fields.

The key objective of the seismic program was to provide more detailed, high-quality infill seismic control in areas that are currently only constrained by a semi-detailed 2D seismic grid of variable ages and quality. This will enable enhanced confidence in interpretation and mapping of structural and stratigraphic characteristics of the subsurface, providing reduced risk in the exploration and development of hydrocarbons from associated reservoir rocks in the program areas. Prospective formations in the seismic program areas are located within the Permian-aged sequences of the Bowen Basin, with the Lower Permian Aldebaran Sandstone representing the primary target.

This report represents the revised interpretation and mapping of the Myrtleville and Punchbowl Gully areas based on integration of the 2019 seismic with vintage seismic and well control in the areas.
