NovoCPT automatically reviews the CPT data and identifies the drill-outs. A drill-out is a depth range where CPT refusal was encountered due to the presence of very dense material. Typically this very dense layer is drilled-out and CPT is resumed below this depth. To see a list of drill-outs go to Data→Drillout from the top toolbar.


The criteria for recognition of a drill-out can be defined in the General tab of the Options page.
