ATP 769 - “ Paranui ”
Overview and Prior Exploration Activity
ATP 769 is located within 5 kms of the producing Moura gas fields. It has the Paranui pilot production wells drilled by Conoco Phillips in 1996 which produced gas for 1 year until the wells were shut in. The production wells were completed using less than ideal completion procedures based upon conventional gas procedures using fraccing and many of the target seams had been damaged by the cement used in casing the wells. More successful techniques, suitable for the local coal characteristics, have now been developed and will ensure greater rates of production.
Current Paranui Work Program
Based on currently available data, WestSide has identified a potential 6,500 acre production area targeting 125 BCF of recoverable 2P gas reserves.
WestSide has drilled three pilot appraisal wells and two observation wells. The pilot production wells are in close proximity to the original Conoco wells. One observation well is located approximately 1 km north-east of the pilot wells to aid the delineation of the resource accessible from the wells, while a central observation well will be equipped with downhole sensors to measure connectivity between the wells across several coal seams. Production testing commenced on the first appraisal well in June 2008 with the other two pilot wells joinng the production test in September 2008.
ATP 688 - "Tilbrook"
Overview and Prior Exploration Activity
ATP 688 is located approximately 90 kms North of ATP 364 and PL 191, which include one of Australia’s largest CSG production areas near Moranbah. The coal measures at Tillbrook are the same coal measures producing at the Moranbah gas project.
ATP 688 has been core drilled with 5 wells all intersecting both the P seam and the Goonyella Lower seam. Both the P seam and Goonyella Lower seams are the seams which Arrow is producing from at the Moranbah gas project. A complete set of testing has been completed including gas content, gas quality, permeability, gas saturation, seam thickness, ash, fixed carbon, moisture, rank and faults and fracturing.
There is evidence of variable levels of ash content, due to volcanic intrusions. The test wells will assess the impact of these ash contents in both P and Goonyella Lower on sustained production. The P seam looks particularly productive, being up to 10 meters thick and demonstrating positive coal qualities, including permeability and rank for CSM production.
Current Tilbrook Work Program
WestSide has drilled two pilot wells and one observation well at Tilbrook. The company has identified a preliminary 16,000 acre production area, which on the basis of yield models is targeted to yield the equivalent to 125 BCF recoverable gas principally from the P seam. The two Tilbrook appraisal wells are being subjected to an extended producton test which commenced in June 2008.
