Project Description

You can drill fast or the bit can last a long time, but you can’t do both—until now. Every driller wants to drill fast, but they also don’t want to spend all day pulling the bit out of the hole because it is worn out. By listening to the noise the bit makes, you can calculate the optimum WOB and TOB to optimize bit life and rate of penetration.

The Solution

A sub that sits just below the kelly and measures strain and vibration. The electronics are powered by rechargeable batteries and wirelessly send the data to the drilling panel in the dog house. The dog house computer used an algorithm to  determine the optimum WOB and TOB to balance the ROP with bit life.
