Cleaning Apparatus TRIZ Cases

Methyl acrylate dissolves insoluble iron sulfide scale without the high toxicity and corrosion risks of strong acids or acrolein.

Acetophenone, butyl glycol, and surfactants in a specific ratio remove drilling mud and oily residues while maintaining environmental safety standards.

A buoyancy assist tool uses a degradable sleeve to retain the wiper plug assembly within its tubular body.

Segmented isolation disks contain pressurized fluid to prevent preferential flow through permeable zones.

Rotating blades in the filter assembly unclog perforations during cementing, preventing valve clogging and ensuring reliable floating equipment operation.

A circulation unit seals against a wireline tool string to enable surface debris removal without extracting the equipment from the lubricator.

Angled flushing outlets direct cleaning fluid into the annulus, eliminating hazardous metal shavings and reducing operation time during well abandonment.

Reverse circulation in a downhole clean out tool removes metallic and non-metallic debris, reducing cleaning time and preventing stuck completion operations.

Segmented wiper cups seal varying tubing diameters, eliminating mandrel curling and supply chain complexity.

Flow-driven turbine rotates mill blades to break and remove sand screen fill, preventing production interruptions caused by calcite accumulation.

A crimped tungsten carbide nozzle prevents erosion and voids by directing slurry into the annulus around the well screen.

Reverse wiper plug removes pipe dope via upward fluid flow, cutting rigless intervention time and costs.

High-density brine microemulsions solubilize oil-based mud filter cakes to reverse wettability, resolving formation damage caused by drilling fluid invasion.

Injecting a choline chloride pre-flush modifies rock wettability, enabling rapid scale inhibitor adsorption and reducing formation damage risks.

A fluid flow activated rotational cleaning tool uses a free-floating outer collar to rotate around a stationary inner collar.

Phosphorus-tagged asphaltene inhibitor tracks concentration to prevent deposition and avoid costly well remediation.

GLDA treatment fluids break down surfactant gel damage to restore formation permeability and reduce costly remedial operations.
