This well was plugged and abandoned with no gas flow to surface.

Keeley-1 spudded at 15.30 hrs (CST) on 22 October 2006.  Keeley-1 was an exploration well that tested a combined Permian anticlinal and stratigraphic trap in the southern Patchawarra Trough of PEL 107. The Keeley prospect was considered prospective by the Operator  because of its similarities with the Raven gas field, located 10 km to the northwest. The Keeley prospect coincides with a robust anticlinal closure. Pre-drill volumetric estimates put its potential mean recoverable reserves at approximately 10 bcf of gas or a maximum potential of approximately 29 bcf of gas if stratigraphic trapping was also involved.

The primary reservoir objectives in Keeley-1 were sandstones of the Patchawarra Formation reservoirs, similar to those which produce gas at Raven (and a number of other successful GOG wells in PEL 106).

Under the terms of a farmin agreement Magellan Petroleum Corporation  funded Great Artesian’s 60% of the Keeley-1 drilling costs in order to earn a 30% interest in any subsequent production licence, in the event of a commercial discovery.

The well reached its total depth of 3059 metres within the Merrimelia Formation at 10:30 pm CST on Sunday 12 November.  Elevated gas readings and fluorescence were encountered in a number of sands that were assessed with DST's and wireline log data.
