Any geomechanical analysis can only be as good as the estimate of in-situ stress. Our
dedicated workflow starts with the analysis of available information on the structural
evolution of your play, and collects available data like stress regime indicators, offset
well information, seismicity, and similar.
With subsequent construction of a rock mass strength polygon for individual depth
levels of interest, possible stress states can be identified; in combination with
additional data we can then determine the sub-regional stress for the site.
The workflow aims both at green field and brown field applications.
Additional information like stress measurements will complement the analysis and
improve your stress model. In hydrocarbon or geothermal applications indirect
information from drilling performance (instabilities, losses, cementing) and
measurements such as SRT, LOT, XLOT, FIT, HF, or MM* will be incorporated and thus
not only improve reservoir understanding, but also the stress model significantly.
* SRT: step rate test, LOT: leak off test, XLOT: extended leak off test, FIT: formation
integrity test, HF: hydraulic fracturing, MM: microseismic monitoring
