    摘要： This invention relates to methods and apparatus for determination of ion concentrations, particularly in downhole water from hydrocarbon wells, aquifers etc. It is useful in a wide range of applications, including predicting the formation of scale and fingerprinting waters from different sources. More particularly, the invention relates to the use of ligands whose electronic configuration is altered by the binding of the scaling ions within a water sample. These alterations are detected electrochemically by applying varying potential to electrodes and measuring current flow as potential is varied, from which is derived the concentration of scaling ions in the fluid.

    摘要： The present invention provides an electrochemical sensor having a solid electrically conductive substrate and a compound immobilized thereon which has binding affinity for an analyte species to be detected and also displays electrochemical behaviour which is modified upon binding of that analyte species, so that binding of an analyte species can be detected by measuring electrochemical properties, such as by voltammetry. Desirably the immobilised compound contains both a first moiety with binding affinity for the analyte and a separate second moiety which is a redox system whose electrochemical oxidation/reduction properties become modified when the first moiety binds the analyte. The analyte binding moiety may be a diol or polyol and preferably is a sugar. The electrochemical sensor finds use in methods of analysing reservoir and process fluids, particularly at a subterranean location. The electrochemical sensor may be a component of a downhole tool, adapted for deployment downhole.

    摘要： The present invention, in one set of embodiments, provides methods and systems for integrating conducting diamond electrodes into a high power acoustic resonator. More specifically, but not by way of limitation, in certain embodiments of the present invention, diamond electrodes may be integrated into a high power acoustic resonator to provide a robust sensing device that may provide for acoustic cleaning of the electrodes and increasing the rate of mass transport to the diamond electrodes. The diamond electrodes may be used as working, reference or counter electrodes or a combination of two or more of such electrodes. In certain aspects, the high power acoustic resonator may include an acoustic horn for focusing acoustic energy and the diamond electrodes may be coupled with the acoustic horn.

    摘要： In an arrangement for monitoring of flow within a hydrocarbon well or reservoir by means of one or more tracers which are placed at subterranean locations such that they may be present in flow produced from the well, the analysis of the flow produced from the well is carried out using an electrochemical method, preferably voltammetry, to detect tracer chosen to undergo a detectable electrochemical reaction. The tracer may be provided as nanoparticles in the well fluid.
