Well Placement Enabling Deep 3D Petrophysics

Recent development in well placement have allowed mapping of the nearby resistivity boundaries and evaluating reservoir structure up to 30m away The new deeper resistivity measurements allow integration of measurement of different scales to propagate the structure with petrophysics parameters far deeper away from the borehole and to provide the best possible geological model populated with properties that can be used to estimate production and completion design. A method is presented that includes the interpretation of a formation structure from the deep directional resistivity tool, correction of petrophysical logs using this structure, refinement of the resistivity model, and propagation of the petrophysical properties. As a results, accessing a more accurate deep formation structure model with a tighter integration with petrophysics provide a more accurate estimation of reserves and production process.
