Abstract

Well tying consists in correlating a synthetic trace to a seismic trace. By opposition to manual labor-intensive approaches, the automatic methods that have already been implemented reduce the global subjectivity induced by the process. This tying process aims at obtaining a local timedepth function at wells location where well logs and seismic information can be retrieved. Using a stochastic approach of the Dynamic Time Warping robust algorithm we shift and warp a computed synthetic trace to match a seismic trace, the match obtained derives from the classic DTW solution. This provides a way to sample uncertainties and the associated well-tie time-to-depth functions at wells location.
