Sunnybank 6 is situated in the ATP 336P permit to the southeast of Roma in Queensland and is operated by Santos with Sunshine Gas holding a 15% working interest.
The well is designed to appraise bypassed oil and gas pay in up to four Triassic reservoirs and two Permian reservoirs in a location a few hundred metres to the east of the Sunnybank 1 discovery well.
Sunnybank 1 (drilled in the early 1960's) flowed 600 barrels of oil per day from the Triassic section, along with 300mcfd of gas however, rates declined during cased hole production testing and the well was abandoned.
Sunshine Gas has also completed the acquisition of a 200 sq.km Overston 3D seismic survey. The data will now be processed and interpreted to allow the optimum location for the Overston 2 gas appraisal well to be selected.
Overston 2 is now anticipated to spud in February of 2004 based on the timing of completion for the 3D seismic processing/interpretation coupled with rig availability.
