Cleaning Apparatus TRIZ Cases

Surfactants prevent microproppant agglomeration, enabling deeper fracture penetration and sustained conductivity in low permeability shale formations.

A temperature-responsive self-degradable temporary plugging agent crosslinks at reservoir heat to form a gel plug.

Cylindrical nozzle directs pressurized liquid through angled apertures to clear well obstructions.

A hydraulically driven hole cleaning apparatus uses a turbine wheel and impeller to transfer mechanical energy.

Polyelectrolyte complex nanoparticles encapsulate oil and gas chemicals, shielding them from hostile down-hole environments while enabling controlled release.

Modified starch and surfactant create a permeable filter cake that eliminates hazardous acid treatments while preventing formation damage.

Expanded deadleg diameter paired with a narrowed inlet restricts water entry and minimizes hydrate formation.

Alkali metal phosphates and organic acids dissolve barium sulfate scales without harming marine ecosystems or corroding equipment.

A bio-derived nano-scale complex dissolves well obstructions and reduces fluid viscosity through electrostatic dispersion.

Self-degrading encapsulating materials prevent premature wellbore reaction and formation damage while releasing acid to enhance pore connectivity.

Ethoxylated amine surfactants stabilize emulsions and inhibit corrosion across varying pH, temperature, and salinity conditions.

Cationic copolymers remove paraffinic and asphaltene blockages from oil wells without interrupting production.

A drillable casing scraper cleans debris and sets isolation tools in one downhole run.

Autonomous offshore chemical treatment system uses platform water infrastructure to perform well maintenance.

A hydraulic mechanical tight hole jar uses a dual biasing system to control mandrel movement and prevent unintended firing.

A terpene-based invert emulsion spotting fluid composition breaks down filter cake seals around stuck pipe using exothermic polymerization.

A downhole tool with a movable sleeve and guide directs dropped balls along a central path, preventing deviation in angled wells.

A downhole assembly uses a porous tubular body to deliver solid chemical treating materials directly into reservoir fluids.

Sliding limit stops apply pull forces to elongate the swab cup, preventing squat damage and reducing maintenance downtime.

A fluid injection device integrates gas lift and chemical delivery through a single supply pipe with independently actuated ports.

An omnidirectional low-density fluid trap prevents production fluid migration into chemical injection lines.

Retractable cleaning mechanisms remove drilling mud from wellbore walls to enable reliable probe sealing.

Vertical gas jets lift debris from sealing surfaces, restoring downhole safety valve reliability without requiring full valve opening.

A hole cleaning function adjusts drag friction factors using cuttings parameters to improve borehole operation efficiency.

Ion-exchange polymer particles capture monovalent and divalent ions, eliminating halite deposition and reducing fresh water consumption.

Milling deformed liner exposes rock; a straddle joint bridges the gap and injects cement to stabilize formation.
