WesternGeco Multiclient 3D Broadband Reimaging Project Underway in the Browse Basin

New geophysical workflow used to resolve imaging challenges and derisk the subsurface

Browse Basin is a proven hydrocarbon province with major gas and condensate fields in the outer and central basin and minor oil discoveries on the basin's eastern margin. Primary exploration targets include Jurassic to Cretaceous basin floor fans with the recent Bratwurst-1 gas-condensate discovery in December 2019, illustrating significant remaining potential proximal to infrastructure.

A new high-end Schlumberger WesternGeco multiclient 3D broadband workflow, incorporating full-waveform inversion (FWI) velocity model building, has been specifically designed to resolve the imaging challenges in legacy data caused by complex overburden, aiding in unlocking previously inhibited reservoir intervals across both held and available acreage. This dataset will aid in derisking additional proximal fan and feeder systems to the southeast of the basin and in the identification of distal fan systems to the northwest.

This exciting project will be conducted in Schlumberger’s Perth office, with final depth-imaged products available in December 2021.
