PREVENT Hydrate Inhibitors

Overview Library

Stop hydrate formation and consequent flow assurance challenges

Hydrate prevention becomes more challenging as production increasingly focuses on marginal fields, deeper waters, and more hostile environments. Inhibitors help to maximize production and protect equipment.

Minimize capex and environmental impact

Schlumberger is at the forefront of industry efforts to develop low-dosage hydrate inhibitors (LDHIs), a more environmentally acceptable, capex-efficient alternative to commonly used thermodynamic inhibitors such as methanol and glycol.

  • Kinetic hydrate inhibitors (KHIs) interfere with hydrate crystal growth or nucleation by embedding themselves into the lattice structure.
  • Anti-agglomerants (AAs) prevent the agglomeration of hydrate crystals into large masses by dispersing water droplets within the condensate or oil phase.

The optimal choice of inhibitor depends on fluid and field characteristics.

For LDHI applications, Schlumberger provides detailed support—such as study of system conditions using phase-equilibrium modeling and advanced equipment for testing under field conditions—to select the most effective treatment.
