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 information on the stress state at the well. The stresses can be reliably estimated away from the well using seismic data, but this can have its pitfalls.
These types of project require different sets of technical expertise and necessitate effective integration between these disciplines. The resulting exchange of data and results provide multiple opportunities for issues or inconsistencies to arise. This presentation discusses our experience in creating 3D analytical stress models from seismic and applying them to different issues facing operators with a particular focus on how to understand the reliability of the estimates and importantly, how to avoid some of the typical pitfalls.
