Drilling Composition TRIZ Cases
- Zirconium Salt Complexes for Rock-Surface Scale Inhibitor Adsorption
Zirconium salts form complexes with scale inhibitors to improve rock-surface adsorption, shorten shut-in time, and avoid concentrated brines.
- Polyvinyl Alcohol-Based Polymer Rheology for High-Pressure Cement Slurries
A controlled storage-modulus slope helps this PVA polymer limit fluid loss without excessive thickening in high-temperature, high-pressure cement slurries.
- 3-HPA-Based Corrosion Inhibitor Composition for Acidic Metal Surfaces
3-HPA precursors form protective films on steel in acidic environments, addressing toxic conventional inhibitors for oil and gas applications.
- Scale Inhibitor-Impregnated Calcite for Circulation Loss Control
Impregnated calcite releases scale inhibitor in the reservoir while plugging loss pathways, combining drilling loss control with production protection.
- Hydrated Flocculated Polymer Composition for Lost-Circulation Sealing
An invert emulsion forms hydrated, flocculated polymer globules that accumulate at pore throats to reduce downhole fluid loss.
- Water-Based Carrier Fluid Stabilization Against Premature Polymer Reaction
Adding the viscoelastic surfactant before salt crystals helps stabilize saturated brine and delay premature polymer reactions at elevated temperatures.
- Friction Reducer Slurries With Thixotropic Suspension Networks
Thixotropic suspending agents form a mesh-like network that keeps friction reducers dispersed during storage and transport.
- Crosslinked Microsphere Plugging Material for High-Salinity Micro-Channels
In-situ microspheres form under shear and swell to plug micro-channels while resisting high temperature and salinity.
