The Perth-based junior has been working with DownUnder GeoSolutions to update on Buffalo, first surveyed in 2004 when computing power was far lower and it says its new and more detailed seismic shows increasingly clear definition around the Elang Formation, the producing reservoir for the field.
The initial plan was to run modern seismic technology "to determine whether seismic velocity issues in the past could be solved with this new technology."
The first iteration appeared to successfully prove this and a second reprocessing iteration was undertaken as an independent check of the initial reprocessing.
All of the things learned from the first two reprocessing iterations were then incorporated into a third processing phase.
Imaging appears to confirm the potential for oil updip of the abandoned Buffalo-5 production well.
The "vast improvement" in data quality increases its confidence in its redevelopment of the field, proving its viability, the company said.
Recently the company also said it was betting on its technical capability to unlock Eagle's potential, saying that the recent Cygnus MC3D survey was expected to create a new standard in the interpretation of the prospectivity of the permit.
Previous interpretation of the area was hampered by "poor quality vintage seismic data".
Earlier this month it updated its prospective resources guide for its Labyrinth project in the underexplored Roebuck Basin on the North West Shelf, with the Ivory prospect alone estimated to hold 420 million barrels.
Hartleys already rates the company a takeover prospect and with updated data and better prospects across its acreage it could provide a possible substitute for those who lost out during the AWE takeover tussle.
The market remained unmoved by the technical efforts with Carnarvon's price not budging at 14.5c this morning
