12.20.1 CuttingsGeology

Container for Cuttings Lithology items. The mud logger at the wellsite takes regular samples of drilled cuttings while the well is being drilled and examines the cuttings to determine the rock types (lithologies) present in each sample. The cuttings samples will typically contain a mix of different lithologies in each sample because there may have been multiple rock types that were drilled within the sample depth interval and there can also be mixing of cuttings as they travel up the wellbore and are collected on the shakers. CuttingsGeology therefore will typically contain multiple lithology elements for each interval so that the percentages of each lithology in the sample along with the more detailed geological description can be recorded.
