Ann: West Erregulla 2 Update - Kingia Encountered, page-4

"Multiple drilling breaks were observed in the upper section of the Kingia with associated elevated mud gas readings. Cuttings from these sections include clean sands with some evidence of grains being coated in what is inferred to be chlorite. Chlorite and illite (which are known to possess anti-diagenetic properties) from the sediments buried and worked in with the sand at the time of deposition are understood to be the key play elements required for the preservation of porosity at depth, and therefore maintenance of good and effective reservoir. This mechanism for porosity preservation is the main ingredient to the excellent reservoirs seen at neighbouring Waitsia gas field. WE2 is currently at a depth of 4,800m (total vertical depth) and based on the original interpretation of the Kingia sandstone thickness, Strike extrapolates that it is approximately halfway through the formation. The large blocky porous sections of sand understood to provide the best reservoir zones at the Waitsia gas field (and other offset wells) occurred within the bottom 25% of the Kingia sandstones. Based on Strike’s interpretation of the 3D seismic, geological modelling and offset well analysis, the company expects to encounter this equivalent section when drilling ahead into the lower Kingia sands."


sounds good to me !
