New Resistivity-Logging Tool Helps Resolve Problems of Anisotropy, Shoulder-Bed Effects

A deepwater operator offshore west Africa needed to drill a successful sidetrack well using oil-based drilling fluid in a complex formation. Using the multiple-DOI features of the Schlumberger Rt Scanner triaxial-induction tool, coupled with near-wellbore measurements from a dual oil-base microresistivity-imaging tool, petrophysicists were able to compute the structural dip accurately. The advantage of multiple colocated triaxial measurements in the tool, and advanced borehole-signal management, provided a deep reading, a more realistic structural dip, and azimuth direction that enabled drilling of a successful sidetrack.
