Over the last two years we have completed a range of projects for our Clients including:

• Studies to evaluate formation water compositions across different areas of the North Sea and Norwegian North Sea. In each case the objectives were to understand the variation of formation water compositions across the areas and use this information to identify the likely source of water being produced from particular production wells.
• Predictions of scaling risks associated with production from gas, gas condensate and oil reservoirs.
• Prediction of the likely organic acid content of formation water in a reservoir and, based on this, prediction of the organic acid content of condensation water produced with gas condensate from the reservoir.
• Prediction of scaling risks associated with produced water injection into a reservoir.
• Evaluation of SO₄-rich formation water analyses from a reservoir, and associated regional formation water analyses, to determine whether the SO₄-rich analyses are likely to be representative of reservoir formation water.
• Evaluation of formation water analyses from several fields from one area of the Norwegian North Sea to determine whether they were representative of reservoir formation water. Where this was not the case, their compositions were corrected for the effects of mud aqueous phase contamination, loss of CO₂ from the samples, exposure of the samples to air, and erroneous sample SO₄ analyses.
• Development of novel methods to track spent acid returns following well stimulation.
• Estimation of formation water compositions for wells producing mixtures of formation water and condensation water, and use of these compositions to predict scaling risks in the wells.
• Prediction of reactions occurring in a reservoir and associated cap rock during and after CO₂ injection associated with a carbon storage project.
