SOFT (incl. soft sticky): Formation types with low compres-sive strength and high drillability like clay, shale, marl, saltand sand, including very soft, sticky gumbo and unconsoli-dated sand

SOFT-TO-MEDIUM: Formation types with low compressivestrength, interbedded with hard layers like sand, shale,chalk and anhydrate

MEDIUM: Hard formation types with moderate compressivestrength, like shale, chalk, anhydrite and sand

MEDIUM-TO-HARD: Dense formation types with high andincreasing compressive strength, but non- or semi-abrasive layers like shale, siltstone, mudstone, sandstone,limestone, dolomite and anhydrite

HARD: Hard and dense formation types with very highcompressive strength and some abrasive layer likesiltstone, sandstone and mudstone

EXTREMELY HARD: Very hard and abrasive formation typeslike quartzite and volcanics
