FAST (Fault Analysis Seal Technology) is a methodology for assessing fault
reactivation in terms of the in situ stress field. Despite its growing use
there has never been a detailed calibration of FAST predictions to see if
they match exploration experience. Fault reactivation predictions are
compared with evidence for hydrocarbon leakage such as Sniffer, HRDZs, ALF
and GOI in the Bonaparte Basin. The likelihood of fault reactivation is
calibrated by this empirical evidence to formulate a quantitative
assessment of reactivation risk.
The FAST methodology is not restricted to assessing fault reactivation only. It may also be used to predict the likelihood of natural fractures being open and hydraulically conductive (fracture susceptibility). An example of fracture susceptibility from the ASPO Hard Rock Laboratory is presented. FAST also forms the basis of a methodology used to risk top seal integrity in terms of brittle failure.
Biography of the Speaker
Scott Mildren completed his PhD at the University of Adelaide in 1997 and
took up a position as structural geologist with Z&S (Asia) Ltd. (now Baker
Atlas Geoscience). At Z&S he interpreted resistivity and acoustic image
data with application to in situ stresses and fracture characterisation.
Scott joined the NCPGG in 1999. His current research addresses various
petroleum related geomechanical issues such as fault and top seal
integrity, fractured reservoirs and wellbore stability. Scott is a member
of AAPG, ASEG, PESA and SPE.
