A Method to Derive Rock Strength from the Drilling Response of Impregnated Diamond Bit
MetadataShow full item record
This research investigates the effect of rock strength on force responses associated with impregnated diamond drilling. The investigation involved coring activities ran on a well-engineered laboratory-scale drilling rig, drilling a collective amount of rock samples using industry graded bit. The experimentation came upon a particular rock-related parameter under the framework of a drilling model that demonstrates a robust linear relationship with rock strength. The investigation leads to estimate uniaxial compressive strength from drilling data.
