Pitless Drilling: A Strategy For Coexistence



Michael Moloney of MI-Swaco setting up the flocculation unit at Arrow Energy’s pitless drilling trial near Miles.

Pitless drilling is being trialled by Arrow Energy to improve coexistence on its tenements with good quality agricultural land.  The trial is also expected to produce cost savings through reducing drilling waste and fluid handling and disposal costs.

Producing CSG on good quality agricultural land.

Arrow has been producing CSG in Queensland's Surat Basin since 2006. The company currently has 300 gas production wells located across four CSG fields centred around Dalby.
The Surat Basin is a large coal bearing sequence in central southern Queensland covering approximately 270,000 km2. It forms part of the Great Artesian Basin that spans much of inland Australia.

Arrow estimates there is 18,000 PJ of gas available from its Surat Basin tenements, far exceeding the State's current domestic gas needs of 150 PJ. Like other Queensland CSG proponents Origin, Santos and QGC, Arrow is planning a CSG-LNG export industry via developing a LNG plant off Gladstone.

Arrow's exploration tenements within the Surat Gas Project area have a significantly different tenure profile to the other Queensland CSG-LNG proponents. A large proportion of the Surat Gas Project area contains some of the most productive agricultural soils in the world and is classed as good quality agricultural land and/or strategic cropping land.
