IADC is The International Association of Drilling Contractors.
Since 1940, the International Association of Drilling Contractors
(IADC) has exclusively represented the worldwide oil and gas
drilling industry.
IADC’s mission is to promote drilling and completion technology;
improve industry health, safety, environmental and training
practices; and champion sensible regulations and legislation which
help safe and efficient drilling.
The first digit represents the hardness of rock formation the
drilling tool buttons are suited for
Every drill bit is designed for a certain type of rock formation,
ranked according to hardness.
The tool is assigned a number between 1 and 8 indicating the type
of rock the teeth or buttons of a drilling tool are designed for:
1, 2 and 3: Indicate a steel tooth. 1 is engineered for soft rock formations, 2 for medium formations, and 3 for hard formations.
4, 5, 6, 7, and 8: Indicates a tungsten carbide insert (TCI).
Within this category 4 is designated for the softer formations,
with 8 representing the hardest formations
The second digit represents further rock formation information
Regardless of tooth type, the second digit takes into account all
factors of the bit and ranks the rock formations the drilling tool
is best suited for on a scale from 1 to 4. 1 represents soft
formations going up to 4 representing the hardest formations.
The third digit represents the bearing type of the drilling tool.
For Example, Tricone bits use different bearings depending on the
type of material to be drilled.
