Directional Drilling TRIZ Cases
- Rotary Steerable Tool Piston Shut-Off Valve for Mud Flow Control
A spool-shaft shut-off valve manages mud flow to rotary steerable tool pistons, supporting steering control while limiting wear.
- Sealed Horizontal Directional Drilling Continuous Coring Device
A sealed pressured horizontal directional drilling continuous coring device integrates an outer tube assembly with an inner tube assembly for precise core extraction.
- Multivariate Seismic Fracture Modeling
Multivariate analysis correlates seismic attributes with petrophysical properties and microseismic data to distinguish natural from induced fractures.
- Adaptive Steering Pad Actuation for High Build Rate Drilling
Segmented steering units with offset pads create opposing forces that axially misalign BHA sections through a flex sub, achieving high build rates.
- Horizontal Dug Well Design for High Yield and Arsenic Control
A horizontal well system captures groundwater through permeable crushed stone fill to increase water yield.
- Drill String Rotation Control for Stick-Slip Mitigation
An automatic drill string rotation controller measures real-time torque and reverses rotation direction to reduce stick-slip friction, extending component life.
