Description and Geology

Gas was discovered at the Palm Valley 1 well in 1965 with the gas primarily reservoired in an extensive fracture system in the Lower Stairway Sandstone, Horn Valley Siltstone and Pacoota Sandstones at depths from 1,800 to 2,200 m. The anticlinal structure is approximately 29 km in length and 14 km in width with well locations initially selected from surface mapping and ease of access.
