Providing technical services to the oil and gas industry and Green Energy

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

Hydrafact is a leading provider of production/flow assurance and PVT consulting and technical services involving the transportation of oil, gas and aqueous phases from reservoir to refinery.

Our experimental services (including an H2S lab) are an important part of the work we do to establish a proper understanding of fluid properties at operating conditions. As a result, our experimental capabilities are the cornerstone of our offering, allowing us to simulate real reservoir and pipeline conditions and use the results to provide clear operational recommendations for our clients.

Our Laboratory facilities

Hydrafact has combined the laboratory facilities of the Centre for Gas Hydrate Research and the Centre for Flow Assurance Research with our own, providing access to some of the most advanced laboratory equipment Worldwide.

Our advanced experimental facilities span a wide range of PT conditions, from very low (-80°C) to very high temperatures (400°C), and from vacuum to ultra-high pressures ( 30,000 psia / 2 kbar). 

The majority of our set-ups are custom built in-house based on designs developed through many years of R&D experience and the full scope of our capabilities can be viewed in our brochure.

Our Technical Expertise

Best-in-field consulting and technical services for the oil and gas industry

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

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

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:

  • Chilled Mirror for determining dew point and dehydration requirements to avoid water condensation, ice and/or hydrate formation
  • Microview Compact Hygrometer for measuring the amount of water in CO2-rich systems
  • Tuneable Diode Laser Absorption Spectroscopy (TDLAS) for determining the amount of water in gas phase
  • Test facilities, including low temperature bath (-80°C) and Anton Paar densitometer, for bubble point and density measurements for CO2-rich systems (e.g., effect of impurities)
  • 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.

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 occurs 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
