Any geomechanical analysis can only be as good as the estimate of the in-situ stress. Our
dedicated workflow starts with the analysis of the available information on the structural
evolution of your play, and collects available data like stress regime indicators, offset
well information, seismicity, and similar.
Possible stress states can be identified with the subsequent construction of a rock mass strength polygon for individual depth
levels of interest; in combination with additional data we can then determine the sub-regional stress field 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. Indirect information from drilling performance (instabilities, losses, cementing) and
measurements such as SRT, LOT, XLOT, FIT, HF, or MM* will be incorporated in hydrocarbon or geothermal applications 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
