Earth Drilling Tools TRIZ Cases
- Retractable Auger Head With Pivoting Cutters
Pivoting hinged cutters reduce the cutter head diameter to fit inside the casing, enabling repair without trench excavation.
- Downhole Tool Power Switch Circuit for Energy Conservation
A downhole tool power switch circuit conserves electrical energy by isolating the main control system from the power source until activation signals arrive.
- Bit Saver Assembly WOB Control via Fluid Diversion
A bit saver assembly manages drilling fluid flow through a spring-loaded inner valve sleeve to regulate weight-on-bit forces.
- Well Prognosis Execution System for Automated Drilling Action Items
A computer-based system analyzes well prognosis documents to identify and execute drilling action items through modular software engines.
