Cleaning Apparatus TRIZ Cases
- Downhole Magnetic Jetting Tool for Ferromagnetic Debris Cleanup
Longitudinally spaced magnets collect ferromagnetic debris, while integrated jetting ports dislodge it for effective wellbore cleanup.
- Oxidizer-Enhanced Solvent Emulsion for Tar Deposit Removal
An aqueous solvent emulsion with an oxidizer breaks down reservoir tar while reducing redeposition and flash-point concerns.
- Hydrocarbon–Ethylene Glycol Packer Fluid for Corrosion Control
Specific hydrocarbon-to-ethylene glycol ratios help passivate metal surfaces, limiting corrosion and protecting packer assemblies in extreme wellbore conditions.
- Tubing Hanger Profile Cleaning With Pressurized Fluid Jets
Pressurized fluid jets remove debris, scale, metal shavings, and viscous fluids from tubing hanger profiles before valve setting.
- Gas-Assisted Wellbore Treatment for Deeper Horizontal Coverage
Gas strips part of a liquid chlorine dioxide and acid treatment into the gas phase, extending chemical reach through long horizontal wellbores.
- Hydrophobic Amine Shale Inhibitors for Clay Swelling Control
Hydrophobic amines adsorb onto clay surfaces while xanthan-based viscosifiers retain fluid, limiting swelling, fluid loss, and stuck pipe.
- Case Guard Substance for Temporary Wellbore Perforation Sealing
A fibrous swelling elastomer with reactive coated alkali particles temporarily seals wellbore perforations during fracking, then degrades with hot water.
- Encapsulated Oilfield Chemicals for On-Demand Thermal Release
Adsorption and unwanted reactions cause transport losses; a protective shell breaks on heating to release oilfield chemicals at the target site.
- Downhole Axial Hydro-Clone Separation for Filter-Free Debris Collection
Filter clogging limits conventional downhole debris tools; an axial hydro-clone uses centrifugal separation to collect more debris per operation.
