Empire is proposing to conduct a 3D seismic survey over the Gingin Gas Fields including parts of the Boonanarring and Bartlett's Well nature reserves, utilising a helicopter assisted or 'heliportable' technique, transporting drilling and seismic receiver equipment by a long-line, suspended beneath a helicopter. The equipment is lowered into position and released at pre-programmed points. Charges are detonated one at a time and seismic data is recorded. Site remediation and site check would occur post survey.
