Laboratory testing

Gas Hydrate and Production Chemistry Laboratory Services

Hydrate testing is our flagship capability, supported by wider oil and gas laboratory analysis for wax, asphaltenes, scale, rheology, separation and fluid characterisation.

Detailed gas hydrate testing capability

Programmes are developed around the technical decision, representative fluid system, pressure-temperature envelope and agreed acceptance criteria.

Kinetic Hydrate Inhibitor Testing

Screen and qualify KHI formulations under defined subcooling and fluid conditions.

  • Induction-time measurement
  • Onset and growth observations
  • Dosage-response assessment
  • Subcooling performance
  • Repeatability and comparative ranking
  • Brine, condensate and oil sensitivity

Anti-Agglomerant Testing

Evaluate the ability of AA formulations to manage hydrate particles under dynamic conditions.

  • Agglomeration and plugging tendency
  • Dispersion and transportability
  • Water-cut sensitivity
  • Oil and condensate effects
  • Dosage screening
  • Comparative formulation ranking

Hydrate Formation and Dissociation

  • Formation and dissociation cycles
  • Pressure and temperature response
  • Thermal cycling
  • Subcooling and hold-time studies
  • Shutdown and restart scenarios
  • Technology benchmarking

H₂S-Capable Hydrate Programmes

Purpose-defined sour-fluid testing subject to technical feasibility and formal safety review.

  • KHI response under sour conditions
  • AA evaluation with representative acid-gas content
  • Materials and containment review
  • Defined operating envelope
  • Controlled test execution
  • Technical interpretation and reporting

High-pressure test platforms

The selected method depends on the technical question and required degree of representation.

High-pressure autoclaves

Stirred or purpose-configured vessels for controlled hydrate formation, chemical evaluation and bespoke studies.

Rocking-cell systems

Parallel screening and dynamic assessment of KHI, AA and hydrate behaviour.

Visual and bespoke cells

Purpose-designed configurations for observation, technology qualification and project-specific protocols.

Temperature control and data acquisition

Controlled thermal conditions with pressure, temperature and test-response monitoring.

Wider production chemistry analysis

Complementary laboratory services support chemical management, fluid behaviour and production risk assessment.

Wax

Wax appearance, deposition tendency, rheology and inhibitor performance.

Asphaltenes

Stability, precipitation tendency, onset assessment and inhibitor screening.

Oilfield Scale

Water compatibility, scale risk, precipitation response and inhibitor evaluation.

Corrosion

Laboratory corrosion assessment and production chemical screening.

Rheology

Viscosity and flow behaviour across relevant temperatures and shear conditions.

Emulsions and Separation

Emulsion stability, demulsifier ranking, foaming and separation performance.

Fluid Characterisation

Targeted analysis of crude oil, condensate, produced water, solids and chemicals.

Bespoke Programmes

Custom protocols integrating laboratory work with engineering consultancy.
