Patent number: 10422922Abstract: A system and method to predict rock strength by directly inverting for petrophysical properties. In one embodiment, seismic data is received or obtained from a seismic survey (step 101). The seismic data are then conditioned (step 103) in order to prepare them for an inversion process (step 105). The inversion process has an embedded rock physics model that allows the inversion to be formulated based upon, and thereby outputting or calculating (step 107), petrophysical properties. Rock strength data may then be calculated from the petrophysical properties (step 109).Type: GrantFiled: April 15, 2013Date of Patent: September 24, 2019Assignee: ExxonMobil Upstream Research CompanyInventors: Xiaoxia Xu, Enru Liu, Dominique Gillard, Yaping Zhu, Kaushik Bandyopadhyay, Fuping Zhou

Patent number: 9696442Abstract: A hydrocarbon exploration method for determining subsurface properties from geophysical survey data. Rock physics trends are identified and for each trend a rock physics model is determined that relates the subsurface property to geophysical properties (103). The uncertainty in the rock physics trends is also estimated (104). A geophysical forward model is selected (105), and its uncertainty is estimated (106). These quantities are used in an optimization process (107) resulting in an estimate of the subsurface property and its uncertainty.Type: GrantFiled: October 3, 2014Date of Patent: July 4, 2017Assignee: ExxonMobil Upstream Research CompanyInventors: Weichang Li, Max Deffenbaugh, Dominique G.
