What will you be doing?

The formation of inorganic, sparingly soluble salts from aqueous brines during oil, gas or water production is known as ‘scale’ and is one of the major flow assurance problems. Scale forms and deposits under supersaturated conditions, wherever the mixing of the incompatible types of water takes place. Or when temperature or pressure changes are severe enough to produce a supersaturated solution. The deposited scale adheres on the surfaces of the producing well tubing and on parts of water handling equipment, where it builds up in time and leads to problems in reservoirs, pumps, valves and topside facilities. The formation of scaling on the inner surface of casings depends on the scaling tendency (supersaturation) of the water and the surface chemistry and morphology of the casing. Steel casings have been shown to be very sensitive for scaling, and many mitigation strategies have been proposed: coatings, scale inhibitors, acids washes etc.

TNO Materials Solutions has designed and built experimental set-up to investigate all the aspects connected to scale management. In this work, you will involve in investigation of scaling deposition mechanism under different conditions and development of experimental systems.

Your tasks and responsibilities include:
  • Literature research to benchmark the know-how present as state-of-art.
  • Develop experimental set-up to meet high temperature and pressure criteria.
  • Evaluate the effect of parameters, e.g., flow rate, temperature, pressure, pH, supersaturation ratio, etc., on scale deposition.
  • Evaluating the effect of organic compounds and microorganisms in formation and precipitation of scale.
  • Evaluate the effect of combination of anti-scale techniques and to developed scale resistant material.
  • Improve Matlab code for image analysis.

What do we require of you?

You are a proactive and independent bachelor or MSc student with background in one of the following areas Materials Science, Physics, Chemistry or applied science background. At the same time, you are seeking for an interdisciplinary and challenging environment within applied research. A hands-on mentality is a must. Knowledge or experience in MATLAB is a plus. Good communication skills in English, particularly for presenting your work and writing reports is expected.

What can you expect of your work situation?

TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society.
