noun
- the quality or degree to which a material, rock, or substance can be drilled or is suitable for drilling
Usage: technical; commonly used in geology, mining, and petroleum engineering
Examples
- The drillability of the limestone formation was excellent, allowing the crew to complete the well ahead of schedule.
- Engineers assessed the drillability of the rock samples before planning the mining operation.
- Poor drillability in the shale layer required the use of specialized drill bits.
- The drillability index helps predict how quickly a borehole can be advanced through different geological strata.
- Factors affecting drillability include rock hardness, porosity, and mineral composition.
