Publication Summary
For many decades, bit wear of firstly steel-tooth, then TCI, and most recently, PDC bits has been quantified using subjective human review of the used bit or even photos of the bit. The IADC Dull Grading method uses guest Imation to report bit wear in fractions (namely 0/8 - 8/8). However, external bit wear is fundamental to correct decisions to select optimal drill bits & features, repair used bits, or even scrap bits. A sub-section of the drilling industry has been attempting to estimate bit wear on "foot-by-foot" data since Bourgoyne & Young published their methodology in 1969. Laser scanning of historical items (European buildings, Renaissance statues, etc.) in recent years has been used to quantify loss of material due to weathering, acid rain, urban pollution, human touching, etc. Geologists are also using the process to evaluate geological features in outcrops. Each drill bit is scanned using laser scanning before and after each bit run and/or repair, and the amount of material lost from either the cutting structure elements of the bit, or the bit body, is quantified and mapped (before and after). Differences for each element can be individually quantified. With the anticipated change in technology (size, cost & usability), scanners would be used next, and finally used on the rig-floor when portable explosion-proof handheld devices come onto the market. Obviously, any oilfield device subjected to wear downhole can also be scanned using this method| Country | United States |
