Combination of Geosteering, Geomechanics and Petrophysics as a New Approach to Support Well Placement

Traditionally the assessment of petrophysical data and geomechanical calculations are divided in time. The geomechanical model is usually build and used before the drilling process, the geosteering technologies are applied during the well placement period, and the petrophysical analysis is performed after the drilling is over. As wells are becoming more complex, a new approach is required to insure the industry efficiency. An ideal concept would be a combination of geomenchanics, geosteering and petrophysics in one comprehensive method to be used at all of three stages of the well placement. Authors review key principles and analyze the practical value of this new approach.
