Metgasco Completes Drilling of NSW CSG Well

Metgasco Limited has completed the drilling of Thornbill E04 coal seam gas exploration well, having reached a total depth of 749.5 metres. 

Drilling has confirmed that the Walloon Coal Measures being targeted were at the predicted depth. Analysis of the coal thicknesses and quality is now underway to better determine its commercial significance, the company said in a statement.

The Thornbill E04 exploration was designed to investigate the thickness and reservoir characteristics of coal seams within the Walloon Coal Measures in PEL 426. 

The well was drilled to an initial depth of 121.3 metres and was then drilled to 473 metres in the Maclean Sandstone, which represents an effective sealing interval within the upper Walloon Coal Measures. Drilling then continued to total depth with the coal portion of the Walloon Coal Measures intersected over the interval 495 to 700 metres, with the top of the coal found to be at the predicted depth.
