  • Patent number: 8429976
    Abstract: An improved manufacturing process for resonator-based pressure transducers is described. The process is a batch process in which several resonators are shaped simultaneously, using an etching process such as plasma etching. The end pieces are also shaped, if required, for several transducers. The end pieces and resonators are sandwiched together prior to separating the individual transducer units. The individual transducer units are then separated using a cutting process. The described process can be used to manufacture pressure transducers having a substantially smaller size, for example 5-6 mm outer dimensions and 2-3 mm resonators. The outer shape of the transducers can be a non-circular cylindrical shape such as that of a right square prism or an octagonal prism.

  • Patent number: 8109143
    Abstract: Methods and related systems are described for a sealed housing for downhole transducers. The housing system includes a housing body and a transducer positioned within the housing body, and one or more flexible members sealably mounted on the housing body. The flexible members each have one or more undulations which facilitate movement of the flexible member in directions primarily perpendicular to the surface of the flexible member. The dimensions of the one or more undulations are designed so as to optimize the ability of the movements of the member thereby accommodating volume changes in the sealed housing. A substantial amount of compensating material can also be positioned within the housing body. The compensating material has a coefficient of thermal expansion substantially less than that of the housing material.

  • Publication number: 20100050761
    Abstract: A gas separation and detection tool for performing in situ analysis of borehole fluid is described. A separation system such as a membrane is employed to separate one or more target gasses from the borehole fluid. The separated gas may be detected by reaction with another material or spectroscopy. When spectroscopy is employed, a test chamber defined by a housing is used to hold the gas undergoing test. Various techniques may be employed to protect the gas separation system from damage due to pressure differential. For example, a separation membrane may be integrated with layers that provide strength and rigidity. The integrated membrane separation may include one or more of a water impermeable layer, gas selective layer, inorganic base layer and metal support layer. The gas selective layer itself can also function as a water impermeable layer. The metal support layer enhances resistance to differential pressure. Alternatively, the chamber may be filled with a liquid or solid material.
