Discovered

Fairview 1 was drilled in August 1994 followed by a number of other wells which subsequently commenced dewatering operations to establish the technical and commercial viability of coal seam gas.

First Production

Gas production commenced in January 1995 with first sales gas in 1997.

Facility Details

Santos acquired the Comet Ridge coal seam gas project comprising Fairview and 4,000 square kilometres of exploration acreage in 2005 through the acquisition and subsequent merger of Tipperary Corporation’s assets into Santos’ gas portfolio.

More than 170 wells have been drilled (at year end 2007) with some 130 wells in the Fairview area.  Of these, 79 are connected and producing to the gathering system with the remainder undergoing dewatering operations and/or awaiting completion and connection.
 
Gas is gathered to two compressor sites (CS1 and CS2) where it is compressed and dehydrated before export as sales to both the Fairview lateral of the Queensland Gas Pipeline system and the newly constructed Comet Ridge to Wallumbilla Pipeline, a 130 kilometre pipeline from CS2 to Wallumbilla.

Following the merger into Santos’ operations on 28 October 2005 and the subsequent integration, extra compression has been brought on line and additional wells connected, which has increased sales gas production by 166%.

Sales gas production is around 70 TJ/day and the average well productivity is 1 TJ/day. Some of the wells are flowing in excess of 5 TJ/day and one well has produced more than 10 billion cubic feet of gas.

In the longer term, additional development and facilities will enable sales gas production to be increased to approximately 200 TJ/day in 2012, with Santos share approximately 140 TJ/day.
