Abstract

In the context of ever more stringent environmental legislation limits regarding the hydrocarbon content of discharge water from offshore oil/gas production platforms, the application of low-field ¹H NMR in combination with solid-phase extraction (SPE-NMR) to quantify the oil concentration of aqueous samples is explored. The methodology assesses both the aromatic and aliphatic content in water in a self-calibrated measurement and compares favourably against alternative, well-established methods. After the proof of concept, the SPE-NMR approach is developed into an automated prototype, which is tested extensively in the laboratory and at an onshore gas plant with artificial and real produced water samples.
