Methods for determining residual surfactant concentrations in oil and water phases |
| abstract |
Methods for determining nitrogen and/or sulfur containing surfactant residual concentrations in oil and/or water phases of an oil and water system, particularly produced oil and water from an oil or gas well, are provided. The methods utilize pyro-chemiluminescence/pyro-fluorescence techniques which quantify the total residual surfactants in both oil and water phases. The methods may be applied broadly in areas where quantifying or monitoring surfactant concentrations in solution is required. |
