...-correlation, deconvolution and reconstruction (Xu et al., 2017). In this paper, we propose a data-driven solution, free of physics-based simulations. It only necessarily requires the casing slowness (i.e., 57us/ft) as input, then works automatically to separate casing waves from original wavefield. In general...

Results validations are also performed by comprehensive log correlations, including the LWD triple combo and the water-filled porosity interpreted from wireline data. Vertical well LWD dielectric permittivity values are obtained by using...

From these initial findings, the authors decided to apply a log shift to the T2 distribution, which is a measure of pore-size distributions, and the resultant T2 distribution with the core GSD matches perfectly...

By pumping fluids at different rates through the main flow line and the inflow line, while monitoring the acoustic signatures using DAS, flow-noise correlations could be derived. Specifically, it will be demonstrated...
