Abstract

O-35 LOPs: “MINIMUM STRESS GRADIENTS” AND IN-SITU STRESS-PORE PRESSURE COUPLING (1) Summary 1 Leak-Off Pressure (LOP) data from six contrasting basins have been examined and plotted on stressdepth plots to establish the lower-bound to LOPs which are proxies for the minimum stress (S3) gradient. Results show these lower-bound trends deviate towards the lithostat with depth in all instances and that the tectonic regime does not effect their shape and magnitude. A subset of the LOP data were paired with pore pressure (Pp) measurements to investigate the extent of Sh-Pp coupling where overpressure increases horizontal stress magnitude. Four of the six
