The Non Stop Driller (NSD) is a sub-based constant circulation system which enables the continuous circulation of drill fluids downhole while making or breaking drill pipe connections. The system has been designed with specific focus on the operators needs by improving drilling efficiency, operational safety, hole condition and equipment integration.
Adrilltech’s patented BitLife real-time bit wear monitoring service combines detection of drilling artifacts with a sophisticated algorithm to make the decision to either pull the bit or to drill ahead to TD. By detecting, comparing, and assessing several features including cuttings character, alkenes and drilling parameter responses such as torque and rate of penetration. This gives an indication of the condition of the bit and its remaining drilling efficiency. The alkenes detected at surface are the unsaturated hydrocarbons which are produced artificially by drilling fluid cracking when high temperatures cased by excessive friction are introduced into the drilling bit and BHA. Adrilltech’ s Software provides objective commercial guidance for optimal timing of bit trips.
