Core Removal TRIZ Cases
- 3D Drill Core Volume Measurement for Fragmented Samples
Electromagnetic 3D scanning compares drill core and tray surfaces to measure fragmented or non-cylindrical sample volume accurately.
- Core Barrel Head Assembly for Real-Time Core Orientation
Integrated sensors and wireless data transfer capture core orientation down hole without extra drill string elements or frequent bit withdrawal.
- Core Barrel Head Assembly for Continuous Core Orientation Surveying
Integrated sensors and wireless data transfer capture core orientation during drilling, avoiding bit withdrawal and reducing downtime.
- Coring Apparatus Inner Barrel Rotation Control
Sensors measure relative rotation between the outer drill bit and inner barrel to prevent core fracturing during drilling operations.
- Pressure Coring Barrel Fluid Retention via Segmented Relief
Segmented core barrel with piston relief prevents fluid loss from high-pressure wellbores by isolating the sample from overpressure events.
- Adjustable Coring Assembly Fluid Balancing
Sliding coupling tube adjusts mandrel length in the coring assembly, balancing fluid pressure between chambers without removing lubricant.
- Frangible Inner Sleeve for Coring Barrel Jam Management
Segmented inner sleeves with varying wall thicknesses break at designated points during compressive loads, maintaining core integrity in deep wells.
- Coring Tool Sponge Gap and Stabilizer Design
A coring tool design positions a sponge material to surround the core sample with a controlled radial gap.
