Cuttings Sampling And Lithology Description
Accurate cuttings descriptions are essential for the following 3 reasons:
- To pick out individual formation sequences as they are drilled, to establish stratigraphic position at all times, and hence to determine casing and coring points.
- To ensure that the well approaches the correct TD.
- To enable construction of a Well Completion Log, with all lithologies accurately described. This log allows detailed correlation to be made with neighbouring wells for development studies.
