Borehole/Well Accessories TRIZ Cases
- Integrated Tubular Fishing Tool Cutting and Retrieval
Integrated fishing tool combines cutting and retrieval operations to reduce well intervention trips.
- Cyclic Pressure Pulses for Stuck Casing Retrieval
Cyclic fluid pressure pulses dislodge settled solids and reduce friction, enabling retrieval of corrosion-fixed casing without complex mechanical tools.
- External Collet High Flow Downhole Lock
Moving locking mechanisms outside the flow path eliminates erosional turbulence and fouling risks while enabling higher injection rates.
- Multi-cycle Downhole Cutter with Nested Knife Sets
Nested expandable knife sets deploy sequentially via a piston assembly to sever multiple casing sections in one trip, reducing extraction time.
- Wellbore Stability Prediction via Caliper Log Feedback
Caliper log measurements validate predicted diameters against actual borehole conditions, calibrating geomechanical models to reduce drilling non-productive time.
- Conjoined Water Sampling and Flow Detection Assembly
A conjoined water sampling assembly integrates a multilevel bailer with a flow detection system for simultaneous subsurface measurements.
- Pressure Compensation Module for Coring Tools
A pressure compensation module equalizes fluid pressures in coring tools using a movable boundary to prevent core sample contamination.
- Slip Wicker Segment Release Mechanism for Anchor Retrieval
A slip wicker segment transitions from immovable to movable under tension to disengage from tubular structures.
- Retrieving Tool for Coiled Tubing Logging Plug
A retrieving tool couples with a coiled tubing logging plug to extract it from fluid tubing.
- Grip Tool Non-Releasing Anchor for Stuck Subterranean Components
A grip tool anchors into subterranean flow tubes using wedged slips and a cone mechanism to secure components during extraction operations.
- Multimodal Jarring Assembly for Stuck Tool Relief
A jarring assembly collides internal impact surfaces to generate shock waves inducing translational and rotational motion in a tool string.
- Coiled Spring Subterranean Tool Actuation
Axially extended coiled spring releases stored energy to expand diameter and drive radial gripping.
- Shifting Tool Puncture Device for Tubular Sleeve Alignment
A shifting tool punctures tubular barriers to engage internal structures without matching keys.
- Sidewall Core Detection Using Force-Location Profiles
Force-versus-location profiles from integrated sensors confirm core retrieval in real time, eliminating delayed detection failures.
- Subterranean Water Jet Casing Cutter System
Hydraulically actuated water jet cutter replaces hazardous explosives and slow mechanical wheels to enable rapid, controlled casing severance in oil wells.
- Expandable Packer With Embedded Flexible Flowline
A downhole packer embeds a flexible flowline in an expandable outer skin that conforms to irregular wellbore walls, reducing sample contamination.
- Adjustable Gauge Mill Blades via Axial Locking Collar
Sloped tracks convert axial collar movement into radial blade shifts, adapting the mill to varying wellbore diameters without complex mechanisms.
- Vented Explosive Pellet Tube for Deep Well Pipe Joint Release
A vented explosive pellet tube equalizes downhole pressure to ensure reliable joint release in deep well drilling operations.
