.... Hence predicting the hydro-fractures can be theoretically achieved once all the above data are available. This is particularly difficult in unconventional and tight carbonate reservoirs, where heterogeneity and highly stress variation, in terms of magnitude and orientation, are expected. To optimize...

... unconventional reservoirs, positioning the wellbore in the appropriate direction for generation of transverse fractures is crucial to achieving optimized well production. Understanding the stress orientation of a field is necessary when determining correct wellbore direction. Especially in areas of high tectonic...

..., the inferred, dominant fracture orientations range between ~S59°W and ~S65°W, consistent with the regional orientations of SHmax. At least one ~N-S oriented fracture intersected the dominant orientations. Using all microseismic event locations, the derived fracture lengths are between ~2,257 feet and ~2,529...

... stimulation. Anisotropic velocity model calibration and sensors orientation were the key factor in the accurate location of Microseismic events in 3D space. Integration of the Microseismic event locations with hydraulic fracture pumping data, prior and post job logs lead to a successful interpretation...

... the understanding of the Geomechanical stress regime obtained through the integration of data from multiple Petroleum Engineering disciplines helped to determine the location & orientation for the first horizontal well in a new Tight Gas discovery. In addition the paper will summarize the results...

..., oriented N-S, and each stimulated with twelve stages. Three of the laterals were geo-steered within a 18 ft target window, whereas one was drilled transverse across a 131 ft window. The production logs were run in the transverse lateral to identify zones in the Haynesville that produced the most gas...

... direction, and the sonic fast shear azimuth (FSA) coincides with the direction of maximum horizontal stress. However, for arbitrary well deviations, breakouts and the FSA are not oriented 90 degrees to each other. Breakout orientations in a deviated well depend on well trajectory as well as in-situ stress...

... log velocities from offset wells were analyzed to estimate the current orientations of the in–situ minimum and maximum horizontal stresses. The predicted orientations of the in–situ horizontal stress were compared to the well azimuths of drilled offset horizontal wells surrounding the property...

... spectroscopy and Spectral gamma logging can help correlating the cementation/ clay distribution within wells. Borehole images are quite helpful in capturing the textural variations which govern the differential diagenesis and also the drilling and natural fractures orientation and their association with rock...
