Brief description
The seismic reflection survey was carried out in the Parish of Darriman, Victoria. The survey was planned to investigate a gravity anomaly, which may be an indication of a structure within the sedimentary section favourable to the accumulation of oil or natural gas. For the most part reflections were exceptionally good, and it was possible to trace one reflecting layer over most of the area. Contouring showed the presence of ananticlinal structure, plunging to the east, but rising and broadening to the west. On the flat crest of the tructure, there is probable closure in two places. The thickness of the Tertiary sediments may be a maximum of 6,000 feet, but may be only 3,000 feet on the crest of the structure and 4,000 feet on the flanks.

Statement: The Darriman area is approximately 110 miles east-south-east of Melbourne and 17 miles north-east of Yarram in
the Victorian Division of East Gippsland.
In 1949, the Robert H. Ray Company of Houston, Texas carried out a gravity survey on behalf of Lakes Oil Ltd. over
an extensive'portion of East Gippsland. The density of stations was greatest in the Lakes Entrance area and decreased to the west and south-west. The Parish of Darriman was the southernmost limit of this survey, and was surrounded by gravity traverses, though none actually crossed it. This work indicated an anomaly, which later work by the Bureau confirmed and showed in more detail. The Darriman area was reported by the contracting company to be
favourable, with good possibilities.
Early in 1952, the Bureau carried out a seismic reflection survey immediately to the north of Lake Wellington, east of Sale (Vale, 1952), where gravity and aeromagnetic surveys had both shown an anomaly. This is the only other seismic survey which has been made in East Gippsland by then.
