Providing Technical Services to the Oil and Gas Industry and Green Energy

Our experimental facilities and modelling capabilities will allow us to simulate real reservoir and pipeline conditions, providing clear operational recommendations for our clients.

Gas Hydrate Technical Services

Wax services

Wax deposition in pipelines and risers is an ongoing challenge for operators, and can have a significant effect on oil production efficiency.

Build-up in pipelines can cause increased pressure drops, resulting in reduced throughput and thus reduced revenue. In more extreme cases, pipelines/processing facilities can plug, halting production and leading to potentially huge losses in earnings.

As a result of increasing understanding of the problems of wax deposition, there are now successful preventative solutions, including chemical treatments and hot oiling. As well as this, Hydrafact have developed a number of reliable in-house methods for studies of heavy hydrocarbon solids deposition in crude oils, including novel QCM and cold finger techniques.

Wax technical services we offer include:

  • Wax appearance and disappearance temperatures (WAT/WDT)
  • Wax formation/dissolution rates
  • High-pressure studies
  • Wax inhibitor performance assessment
  • Co-Axial Cold Finger with Shear and temperature gradient through flowline (2,000 psi)
  • High pressure QCM cell with temperature gradient & shear (10,000 psi, -20 up to 250 °C)
  • Wax Early Warning System
  • Wax Inhibitors Evaluation

Asphaltene services

Asphaltene deposition can present a major flow assurance challenge.

Deposition can occur in various parts of the production system including well tubing, surface flow lines and even near the wellbore. The conditions of asphaltene deposition are controlled by factors such as pressure, temperature, composition and flow regime. Asphaltene deposition and fouling of flowlines/facilities can greatly reduce productivity and increase operational costs through the requirement for frequent chemical treatment and removal of deposits.

Asphaltene technical services we offer include:

  • Asphaltene content determination (ASTM D 6560)
  • Asphaltene deposition at high-pressure conditions
  • Asphaltene Onset Point (Upper and/or Lower)
  • Asphaltene Inhibitor Evaluation, etc.

CO₂ Rich Systems

Hydrafact and Heriot-Watt University have acquired extensive experience relating to phase behaviour and properties of CO₂- Rich systems in the presence or absence of water and oil.

Our experimental facilities include:

  • Test facilities, including low temperature bath (-80°C)
  • Anton Paar Rheometer and capillary tube for viscosity measurements
  • Pendant drop and capillary rise for interfacial tension measurements
  • Slim tube facilities for Minimum Miscibility Pressure (MMP) measurements
  • High-pressure glass micro model and visual cells for simulating CO₂ injection in depleted reservoirs or saline aquifers.

In addition, our comprehensive thermodynamic model HydraFLASH has been tuning and validated using literature and in-house data for predicting phase behaviour and properties of CO₂-rich systems.

H₂S LABORATORY

Around 2010, based on industrial demand we build an H2S compatible laboratory at Hydrafact

Typical Projects Include:

  • Study on Reversibility of KHI Precipitation with Temperature: Full CGI Approach
  • Study on Reversibility of KHI Precipitation with Temperature: Induction Time Approach
  • Hydrate Laboratory Study
  • KHI Fouling Mitigation

And a lot more

Salt Deposition Services

The precipitation of salt (e.g. NaCl, KCl) is a serious problem and can block the flow path of hydrocarbons.

Salt scaling is particularly severe in wells with high saline (>200 g/l) formation brines which may be near saturation with respect to sodium chloride. The phenomena occur more frequently in gas wells than in oil wells, and can be caused by low pressures, decreasing temperatures and/or the addition of organic hydrate inhibitors.

Salts readily adhere to surfaces, particularly rough surfaces, and are capable of forming very dense plugs, severely restricting flow and thus production efficiency.

Our experimental facilities include:

Salt deposition technical services we offer include:

• Measurement of salt solubility at surface and reservoir conditions, including the effects of organic inhibitors

• Assessment of salt inhibitors (e.g., crystal grow modifiers) on deposition conditions and surface adherence

Kinetic Hydrate Inhibitor (KHI) Removal

Hydrafact has developed and patented a technique for KHI Removal from produced waters based on solvent extraction using treatment chemicals

This simple method maximises KHI removal and reuse for economic and enviromental benefits and resolves many potential produced water processing
