Abstract: A method for inhibiting the formation, deposition and adherence of scale to metallic and other surfaces in the equipment, vessels and/or piping of facilities for the handling of oil and gas produced fluid is disclosed. An effective scale inhibiting amount of alginate is added to a produced fluid containing a scale-forming divalent cation. The alginate effectively cross-links with a scale-forming divalent cation, e.g., calcium, forming an alginate gel for subsequent separation and removal from the produced fluid.

Abstract: The invention relates to a sensor assembly to detect and quantify organic and/or inorganic mercury compounds, including elemental mercury that may be present in gases or liquids, such as natural gas, air, condensates, crude oil, refined petroleum gas or liquids, and water including connate water, condensed water and water containing hydrate inhibitor(s). The sensor assembly includes a housing having a flow channel defined by an inlet, a sensor array, and an outlet. The sensor array is based on the differential sorption properties measured using a surface acoustic wave (SAW) sensor array, a chemiresistor array, or a combination of the two.

Abstract: A cartridge sampler for collecting a target species from an environment for subsequent chemical analysis includes removable collection media having at least one molecule sensor thereon. The cartridge sampler includes a means for tagging a geospatial location and time that the fluid samples are provided to the collection media such that the location and time that the fluid samples are provided to the collection media can be later determined. Also disclosed are systems and methods for collecting species from various environments including a subsurface formation, a pipeline, and gaseous, soil or sub-slab, and aqueous environments. The cartridge sampler is fitted on or within a device designed for moving within each environment.

Abstract: Disclosed are processes for removing carbon steel components of a subsea oilfield facility in a subsea environment by accelerating the corrosion of the carbon steel components in the surrounding seawater, by a passive and/or active impressed current method. In the passive method, the facility is connected to a cathodic metal of greater electrical potential, such as copper. In order to cause the maximum and uniform corrosion, it is preferred that a wire of the chosen cathodic metal be extended along the facility and through pipelines. In the active impressed current method, an external DC electrical supply is used to apply an electrical potential difference between the steel components of the facility and the cathodic metal.
