Reservoir Fault Properties Estimated Using
Seismic Shale Gouge Ratio
A.D. Irving* (Total E&P UK Ltd), P. Breton (Total SA) & S. Guillon (Total SA)
SUMMARY
Fault properties estimated using lithoseismic Vclay are compared to those derived from a classical
geomodelling approach with reservoir NTG. Throw and Shale Gouge Ratio (SGR) calculation at the
seismic scale can provide a significant improvement in resolution and accuracy over the geomodelling
approach. Fault properties included in numerical reservoir simulations give a qualitative match to
observed production and time-lapse seismic effects in an offshore turbidite field. Errors introduced during
upscaling of seismic properties into ‘stairstep’ faulted grids can be overcome using a virtual deformation
of the grid geometry. This method could be extended to upscaling fault permeability estimated from
seismic SGR.

Понятие SGR как меры глинизации разломов за последние 10-лет вошло из теории в практику
Насколько я понял бросив взгляд авторы картируют мощности пластов глин и потом оценивают SGR для разломов
