Abstract
A seismic velocity survey was carried out in Associated Freney Oilfields Nerrima No. 1 Bore by the Bureau of Mineral Resources on the 10th August 1955. The well is situated on the Nerrima Dome in the Fitzroy Basin, W.A. Some trouble was experienced with cable breaks for the shallow part of the hole, but in general it was possible to recognise the true formation break. Average measured velocities ranged from 8000 ft/sec near the top to 12,200 ft/sec for the total depth of the bore.

Lineage
During 1955, Associated Freney Oilfields drilled a bore, called AFO Nerrima No. 1, on the Nerrima Dome in the Fitzroy Basin, W.A. The company requested the Bureau of Mineral Resources to carry out a seismic velocity survey of the bore. The Bureau's seismic party, which was operating in the Fitzroy Basin at the time, performed the survey on the 10th August 1955. The Nerrima Dome is an anticlinal structure situated on Nerrima Station in the Kimberley Division of Western Australia. The Dome lies within the geological province known as the Fitzroy Basin, and is exposed in Permian sediments of this Basin. It has been mapped in detail by a Bureau geological party in 1948 (Guppy, Cuthbert and Lindner, 1950). A previous bore had been drilled in 1939-42 by the Freney-Kimberley Oil Co. on the structure, but because of drilling difficulties, this had only penetrated to 4271 ft. A seismic survey of the Dome was carried out in 1952 (Vale, Smith and Garrett, 1953). Reflection profiling was attempted at first, but results were so poor that this was abandoned. A rather unsatisfactory refraction survey was then completed and, after consideration of the results, the site of the present bore was chosen.
