Sunnybank 6 reached total depth of 2,192m and a full suite of wireline logs were acquired. Drill-stem test 2 over the interval 1,972 to 1,990m in the Bandanna Formation mal-functioned and hence was re-tested post logging operations. DST 3 tested the same interval as DST 2 and flowed only minor gas to surface.
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 was 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.
