Asphaltene Dispersants
PZT-ASPH-1 asphaltene dispersants are surfactant/polymeric additives designed to interact with asphaltene aggregates in crude oil. They adsorb onto asphaltene aggregates, sterically and electrostatically preventing them from flocculating and precipitating out of solution as pressure, temperature, or composition changes during production and transport - particularly near the bubble point where pressure depletion triggers instability. Prevents a notoriously difficult-to-remediate flow-assurance problem: once asphaltenes deposit as a hard, adherent, scale-like layer, mechanical or chemical removal (often aromatic solvent soaks or coiled tubing) is far more expensive than ongoing dispersant treatment.

Use Cases & Applications
- Flow-assurance treatment for crudes with high asphaltene content
- Prevention of deposition in tubing, flowlines, and surface facilities, particularly near the bubble point where pressure depletion triggers instability
Pros
- Proactive treatment is far cheaper than reactive remediation
- Can often be co-injected alongside other production chemicals
Cons & Limitations
- Asphaltene stability is crude-specific and hard to predict without dedicated lab testing (SARA analysis, asphaltene onset pressure testing)
- A dispersant that works for one field's crude can fail for another
- Purely preventive - does not dissolve existing deposits
