Paper Number: SPWLA-2023-0067
... to the proposed workflow to mitigate nuclear-log acquisition noise. Estimation results are used to calculate storage and flow properties based on appropriate petrophysical models. The general inversion-based T-S estimation method overcomes practically all the limitations of the standard T-S approach such as (i...

..., . . and . respectively, are determined by the AHD, I, and A measurement uncertainties, . . and . respectively, of each individual interval (Bolt and Harbidge 2023). Interpolation of interval uncertainties between waypoints gives a description of the positional uncertainty of the calculated 3D positions. When 3D data...

... to be challenged by the core data established for calibration. The core T2 and PTR distribution data acquired for calibrating the calculation of PTR and kk, was observed to deviate from the general and expected simple chalk behavior. Despite these complications, a modified workflow was developed, enabling...

.... Crossplots hosting multiple templates are used to verify clean and shale calculations that separate shales, high porosity-high perm sands, and low porosity lowperm sands. Porosities and perms are in places greater than 25% and 0.1 mD, respectively, in shoreface, delta, and transgressive deposits at 350-425...

.... Traditionally, mud-loggers determine the depth origin of the sampled cuttings by calculating the lag time required for the cuttings to travel from the bit to the surface. These calculations, however, can contain inaccuracies in the depth correlation due to the shuffling and settling of cuttings as they travel...
