D048 A New Methodology for Effectively Correcting LWD Depth Measurements G.A. Bordakov* (Schlumberger) A.V. Kostin (Schlumberger) J. Rasmus (Schlumberger) & H. Laastad (Statoil) SUMMARY LWD or drilling derived logging depths can be inaccurate and therefore unreliable for well-to-well correlations correlations to offset well data and formation thickness determinations. These inaccuracies generally originate from the fact that the LWD depth measurement is purposely made to equal the driller’s depth. The actual depth of the measurements downhole is rarely equal to this static pipe measurement for the primary reason that while drilling the drillpipe is subject to an environment that is not
