Fluid Removal TRIZ Cases
- Reactive Well Sealing Composition for Fluid Loss Control
Metal oxide packing with silicate-silane sealing cures in subterranean formations to block fluid migration and maintain hydrostatic pressure.
- Well Log Fluid Property Prediction for Low-Permeability Reservoirs
Transforms built from multi-depth fluid samples and well logs predict unsampled formation fluid properties for better reservoir development planning.
- Thermal Post-Treated Coke Proppants for Stronger Fracture Conductivity
Thermal post-treatment of fluid coke and flexicoke proppants boosts strength and fracture conductivity to support higher hydrocarbon recovery at lower cost.
- Perforating Gun Sacrificial Fill for Hoop Stress Relief
A sacrificial fill inside the charge tube absorbs and redistributes detonation pressure to limit hoop stress, gun deformation, and sticking.
- Differential Pressure Friction Monitoring in Fracture Fluid Conduits
Differential pressure ports in a fracture fluid conduit enable real-time friction tracking and additive adjustment for more accurate hydraulic fracturing.
- Wellbore CO2 Saturation Control Using Relative Permeability Modifiers
Relative permeability modifiers raise residual CO2 saturation in wellbores, improving hydrocarbon recovery while cutting surface handling costs and emissions.
- Autonomous Ballistic Arming for Safer Perforating Gun Assembly
A movable ballistic barrier keeps the detonator integrated yet isolated during shipping, then aligns it automatically when perforating guns engage.
- Hydrocarbon Well Interference Detection Using Surface Pressure Modeling
Surface production data and reservoir pressure simulation reveal interwell interference early and trigger automated well responses without downhole sensors.
- Two-Stage Expandable Liner Hanger for Full Cement Coverage
Staged expansion anchors the liner first, keeps cement flowing through the hanger, and then seals the casing for full coverage.
- Integrated Downhole Plug and Perforating Tool for Single-Run Well Killing
Combining plug setting and tubing perforation in one downhole run cuts well kill preparation time and enables kill fluid flow into the annulus.
- Corrosion Inhibitor Composition for Acid-Treated Fracturing Sand
Acid-treated local fracturing sand uses alkenylphenone and azanaphthalene inhibitors to remove calcareous material while protecting equipment.
- Well Operation Anomaly Detection Through Event Change Classification
Classifying well parameter changes into event patterns helps detect anomalous operations in real time across many wells with less manual analysis.
- Functionalized Cellulosic Nanoparticles for Reservoir Wettability Control
Hydrophilic and hydrophobic cellulosic nanoparticles redirect reservoir flow, boosting hydrocarbon movement while limiting water bypass.
- Casing String Pressure Control Through Brine Injection Into Micro-Annuli
Periodic annuli bleed-off and brine injection stabilize casing string surface pressure by establishing micro-annulus injectivity.
- Slidable Sand Screen Assembly for Downhole Compaction Resistance
Sliding sand screen extremities and helical ribs let a downhole completion absorb formation compaction and prevent buckling.
- Autonomous Inflow Control for Well Fluid Differentiation
A deflection surface and self-actuating outlet separate water from mixed well fluids without orientation-sensitive float detection.
