The well is located near Boonah, roughly 50km south-west of Brisbane. About 24 metres of net coal was intercepted in the well with one particularly thick coal seam of 8 metres thickness at a depth of 430 metres.
“This is an exploration hole and as such the well has a diameter of only six inches compared with 16 inches used for production enhancement purposes in the Surat Basin production wells,” Arrow said in a statement.
“However, even without these enhancements the well flowed 200,000 cubic feet per day on test. After shut in the wellhead pressure built up to 260 psi.”
Silverdale-1 is the first CBM well to be drilled on the western flank of the Clarence-Moreton Basin in an area known as the Laidley Sub-basin. This is a feature about 80km by 25km running the length of the basin. Arrow Energy has 100% equity in the area.
