Gas Hydrates

Gas hydrate technical studies we offer include:

Hydrate measurements for multicomponent systems containing

  • Gas (natural gas, CO2...) and liquid hydrocarbons (oil, gas condensate...)
  • Condensed water and formation brines
  • Organic inhibitors (alcohols, glycols...)
  • Drilling muds and completion fluids
  • Wax (e.g. solids co-precipitation studies) and inhibitors
  • Corrosion inhibitors
  • Hydraulic fluids
  • Process/product gases/liquids and chemicals

Phase compositional analyses

  • Amount and composition of hydrates
  • Aqueous and hydrocarbon phase compositions
  • Inhibitor (e.g. methanol) loss to the vapour phase
  • Water content of natural gases
  • Simulation of various production scenarios (e.g. subsea separation)

Low Dosage Hydrate Inhibitor (LDHI) performance and screening

  • Kinetic inhibitor (KHI) induction times
  • Hydrate formation and dissociation rates
  • Simulation of various operating scenarios (e.g. shut-in, start-up)
  • Compatibility of other production chemicals (e.g. corrosion inhibitors)

Anti-Agglomerant performance and Cold Flow/Hydraflow studies

  • Viscosity of hydrate/water/oil slurries
  • Effect of water cut, salt, natural inhibitors
  • Simulation of various operating scenarios

Flow loop studies

  • LDHI assessment
  • AA performance
  • Cold Flow/Hydraflow development
  • Hydrate monitoring and early warning systems

Hydrate blockage removal and other studies

  • Removal of hydrate blockages in wells and flowlines
  • Hydrate formation, prevention and plug removal during shut-down and start-up
  • Hydrate formation/prevention in chokes and control valves
  • Hydrate formation risks in HIPPS impulse lines
