    摘要: A method of sampling a multi-phase fluid stream is provided which comprises the steps of: sampling, with a sampling probe, a portion of the fluid stream; measuring the flow rate of said sampled portion; and measuring, independently of the sampling step, the total flow rate of the fluid stream, wherein the flow rate of the sampled portion is controlled according to the ratio of the flow rate of the sampled portion to the flow rate of the fluid stream, in order to obtain substantially isokinetic sampling of the fluid stream. The method may provide isokinetic sampling to an accuracy of 5% or less and preferably only samples a small portion of the fluid stream. The method has particular application for high rate condensate gas wells. A corresponding sampling system is provided which has particular application in the sampling of streams from well-heads. A flow conditioner for use with sampling methods and systems is also provided, the flow conditioner being a pipe section including: a swirl inducing section; a flow straightener, and an orifice plate.

    摘要: An immersion probe is described that includes sensing elements that allow for hydrate inhibitor dosage to be more efficiently provided into gas and/or oil wells. The immersion probe allows for detection of first appearance of water in a multiphase flow in a well, measuring the amount of inhibitor in water within the well, determining an accurate water-cut, and measuring other property such as water salinity. Accordingly, with the known water-cut, salinity and the water flow rate inferred from the inhibitor injection flow rate and inhibitor-in-water fraction, a correct dosage of the inhibitor can be injected to the well in order to prevent hydrate formation, while reducing overdosing. Water flow rate may also be inferred from an independently measured liquid flow rate and the immersion-probe measured water cut.

    摘要: A method and apparatus is disclosed for estimating brine water conductivity in a multiphase mixture of brine water and other substances by combining measured mixture permittivity and conductivity with a known or derived relationship between brine water conductivity and brine water permittivity. The mixture permittivity and conductivity are measured using an open-ended coaxial probe or other probes at microwave frequencies. A number of applications for the brine water conductivity estimate are disclosed including making salinity corrections of a dual energy flow meter.

    摘要: A centralized location system includes a location update application programming interface (API) to receive varying types of location inputs for a user from at least one location-providing application. A memory stores a location of the user and the location inputs, wherein the location update API periodically updates in the memory the location inputs when location updates are received from the at least one location-providing application. A location export API, upon request from a location-based service application, processes the location inputs to estimate a location of the user, which location estimate replaces the stored location in memory and is sent to the location-based service application. A user interface enables the user to specify a location granularity for at least one of the at least one location-providing application and the location-based service application.
