Project Profile
Location: Gladstone, Queensland, Australia
Reserves: 3P gas reserves of 2,467PJ and 2P gas reserves of 59PJ
Exploration start-up: 2009
ATP 1025P - Comet Block is located about 300km northwest of Gladstone, Queensland, Australia. Bow has obtained 3P gas reserves of 2,467PJ and 2P gas reserves of 59PJ in the Comet Block. Bow is in the process of trialing several completion techniques in the Blackwater CSG Field to deliver commercial gas flow rates. As a part of the ongoing production enhancement operations, Bow is testing fracture stimulations of target coal seams to increase gas production. This process is commonly referred to in the industry as fracing.
The fracture stimulations are designed to enhance the existing permeability and thereby improve fluid and gas flow rates. Fracture stimulation completions have resulted in commercial gas flow rates elsewhere in the Bowen Basin. Bow closely monitors its operations and follows strict procedures in relation to environmental and operational management, in accordance with Queensland’s environmental regulations.
Initial fracture stimulations (fracs) have been completed on the northern ‘four spot’ CSG fracture pilot, located about four kilometres west of the Blackwater Power Project. The fracs were successful at fracturing the targeted zones and pumping sand to prop open the induced fractures in the coals. All of the fracced wells are expected to be completed for production testing during November. Lateral Drilling commenced after vertical wells encounter free gas and inferred permeability in the thick target coal.
The vertical production and flush wells for Bow’s first lateral CSG pilot program have been drilled and cased. The target seam varied in thickness from four to eight metres and the vertical wells encountered live gas shows and good indications of permeability during post-drilling flushing of the holes. A surface to inseam (SIS) lateral rig is being used to drill the lateral well pilot program. Lateral drilling and completions have been successful in obtaining commercial gas flow rates in adjacent tenements and numerous other CSG and underground mine areas of the Bowen Basin.
