Cleaning Apparatus TRIZ Cases

Introducing a banana-based aqueous fluid into the wellbore separates oil and water phases to remove filter cakes without damaging the geological formation.

A jet sub redirects driving fluid at an obtuse angle to mix with induced fluid for wellbore cleaning.

Skin profile analysis selects optimal wells for targeted acid injection, reducing operational costs while improving production performance.

Segmented plugs prevent fluid coning by absorbing pressure stress on cement barriers.

A ported sub positions cleaning tools above the packer to circulate debris uphole, preventing seal sticking and eliminating separate cleaning trips.

A hydrate inhibitor composition uses polar and nonpolar solvents with polymers to delay gas nucleation.

A debris removal tool uses a bottom-end fluid jet system to break up well bore obstructions while collecting material in a strainer basket.

A downhole tool creates a hydraulic barrier above the collection opening to restrict upward fluid movement and direct debris into the capture zone.

A variable flow diverter tool redirects pressurized fluid away from downstream components using a movable inner sleeve and spring mechanism.

A single-phase fluid disperses organic deposits and dissolves inorganic scale within a wellbore using solvents, surfactants, and co-solvents.

A sectional pumping apparatus integrates a submersible pump and swab tool within a concentric well casing configuration.

Active wall heating prevents hydrate and wax buildup, resolving reliability issues from unpredictable temperature changes.

Monoamine and diamine corrosion inhibitors in hydrochloric acid reduce steel corrosion rates to acceptable levels across 20°C to 135°C temperatures.

Magnetic retention prevents premature extension of downhole cleaning elements during run-in, avoiding shear pin failure from metal fatigue.

Radially inward protrusion cleans cone surface during running-in phase to maintain seal integrity.

Nested casing scrapers remove debris and burrs before the completion assembly encounters them, eliminating separate de-burring trips.

A thermochemical mixture generates heat and pressure to solubilize wellbore damage.

Acute angle fluid conduits direct bypassed drilling energy toward the annulus, preventing vortex formation and reducing solid particle accumulation risks.

Surge tool lowers casing pressure to draw annular debris through perforations, eliminating separate cleaning steps for reliable cement plugs.

A gas-liquid spacer acts as a phase-changing plug to separate injected natural gas from liquid pockets in subsea pipelines.

Viscosified remedial fluids deliver uniform placement in subterranean formations by self-diverting to low permeability zones, eliminating gel residue damage.

Merges stimulation vessel pumping with offshore injection systems to expand inhibitor treatment volumes, eliminating sulfate scaling and bacterial growth.

A wellbore cleanout tool uses an electromagnet and permanent magnet to attract metal debris into a movable sleeve collection basket.

Integrating the valve unit inside the pressure chamber eliminates external controls, resolving space constraints while maintaining operational reliability.

Spring-biased retractable mill blades span the entire inner circumference of a wellbore casing to clean interior surfaces.

Radial inlets and adjustable wrap sleeves on a remediation packer isolate contamination zones, enabling targeted vacuum extraction without removing clean water.
