Perth based junior oil and gas company Carnarvon Petroleum has been working with seismic reprocessing firm, DownUnder Geosolutions to provide an update on Carnarvon’s Buffalo project.
Quality new seismic data has recently been received showing clear definition around the Elang formation, the producing reservoir in the Buffalo oil field.
With this new data the reservoir in this region is clearly identifiable on seismic and has been reconciled with important well data within the oil field.
Carnarvon secured the Buffalo project in 2016 with the objective of running modern seismic technologies (Full Waveform Inversion or FWI) to determine whether seismic velocity issues in the past could be solved with this new technology. The first iteration appeared to successfully achieve this objective and a second reprocessing iteration was undertaken as an independent check of the initial reprocessing work. All of the learnings from the first two reprocessing iterations were then incorporated into this current third reprocessing iteration. The result is a data set that is a vast improvement on the historic seismic data that was available when the field was last in production
This improvement in data quality increase’s Carnavon’s confidence in the redevelopment of the field.
