The system can be used in a subsea location, on the surface or in any other condition where it is connected to a flow of different phases of gas and/or liquid. The samples obtained are representative in composition of the phases flowing at well head conditions in terms of both pressure and temperature. Additionally, a relatively small volume of each phase is used in obtaining the samples. The system connects and disconnects to ports installed at the sampling location nearby the wellhead or the production line. The sampling flow is controlled by means of a pump. The collected samples are separated in mono (or nearly mono)—phase samples (oil, water and gas) and stored in individual bottles.

  • Publication number: 20140041446
    Abstract: An apparatus and system for passively sampling production fluid from a well is presented. The passive sampling device is used to split two-phase flow and provide a driving pressure differential for a sampling system. Flow through sampling systems require a low pressure differential to be utilized to take a liquid sample, so that the sample retained remains isobaric. When performed in two-phase flow, the pressure differential needs to be relatively high, potentially yielding a non-isobaric sample. By separating out the liquid content of the flow, a low driving pressure is allowed to be used. Thus, this keeps the sample isobaric at a wide range of production flow rates.

    Abstract: Apparatus and systems, as well as methods, may operate to draw a formation fluid sample into a sampling port included in a down hole tool or tool body, to vaporize some part of the fluid sample to substantially fill an injection port with a gas phase, to differentiate gas components in the gas phase to provide differentiated gas components along a concentration gradient in a receiving section, to detect the differentiated gas components with a detector, and to determine a fingerprint of the differentiated gas components. A reaction section and a vacuum section may be used for waste consumption and/or absorption.

  • Patent number: 8360143
    Abstract: A method of determining a concentration of a component in a flow from a single source or layer contributing to a total flow using the steps of measuring the total flow rate at various depths and sampling the total flow at a depth between two successive sources, measuring a total concentration of one or more flow components within the total flow, repeating the measuring of the total flow rate, the sampling and total concentration in further intervals separating other pairs of successive sources, and determining the concentration of at least one component by solving a system of mass balance equations representing the total flow of the flow components at each sampling depth.

  • Patent number: 8215390
    Abstract: A coiled tubing deployed fluid sampler (50) for collecting a single phase fluid sample from a well. The fluid sampler (50) is actuated to establish fluid communication between an interior (56) and an exterior of the fluid sampler (50) such that a fluid sample is obtained from the well in a chamber (92) of the fluid sampler (50). The fluid pressure in the coiled tubing string is then increased, which pressurizes the fluid sample in the chamber (92). Thereafter, the coiled tubing and the fluid sampler (50) are retrieved to the surface with the pressurized fluid sample remaining above its saturation pressure during collection and retrieval to the surface.
