When can seismic data be used to predict subsurface stress

Induced seismicity, casing deformation, fracture stimulation design and well planning all require an understanding of the in situ stress state. Stress models are typically built in 1D along well profiles where sufficient data is available. However, this only provides accurate i... Read More.

The present-day stress field of Australia

The unusual present-day crustal stress pattern of the Australian continent has been the subject of scientific debate for over 25 years. The orientation of maximum horizontal present-day stress (SHmax) in continental Australia is unlike all other major tectonic plates in that the ... Read More.

Facies-based inversion through the asset lifecycle

Seismic lacks low frequencies, so for an absolute seismic inversion (which allows us to be quantitative) a so-called Low Frequency Model (LFM) is required.  Starting from an empty LFM, we would of course like to post Sand Vp values where there is Sand, Shale Vp values whe... Read More.
