    • A non-invasive method and system for reliably locating underground pipes, particularly non-metallic pipes. The invention uses portable seismic generator to direct seismic waves into the earth at a downrange sampling location suspected to overlie a buried section of pipe. The seismic waves are imbued with a distinctive attribute, such as a predetermined frequency or digital pulse. Upon encountering the pipe, seismic waves are efficiently converted to longitudinal waves which are conducted lengthwise along the pipe to an accessible region. A receiver coupled to the accessible region is tuned to detect vibrations that carry the distinctive attribute. The receiver wirelessly transmits data indicative of the intensity of detected vibrations to a remote communicator which may be attached directly to the seismic generator. By sampling several locations in near vicinity, the most probable location of the buried pipe can be deduced.

    • Systems and method implement end-to-end capture of data fluents, the treating of said data locally, transmission of the data to a scalable server infrastructure, and retrieval and visualization of the data in a computationally efficient manner. Data is retrieved using a local electronic device that immediately time stamps data values and stores the values on a local buffer in order to compensate for any wireless signal vagaries. Local wireless configuration of the device consists of wireless-based configuration interactive menus, enabling high ease- of-use during setup and administration. Data is then communicated during times of Internet connectivity to an online data storage repository. The online data repository, in turn, resamples the incoming data across temporal resolutions to aggregate efficiently for data visualization at any temporal resolution downstream, then provides data retrieval services for Internet-based visualization algorithms that request and serve data at appropriate resolutions for user need.

    • This application relates to fibre optic distributed acoustic sensing (DAS) applied using a sensing optical fibre (104) that is at least partly embedded in a cement structure (203) and addresses a problem of different acoustic sensitivities at different parts of the fibre (203). A method of producing an acoustic sensitivity profile is described which involves monitoring (501) temperature along the length of the optical fibre during curing of the surrounding cement structure. A temperature profile(301, 302) can then be generated (502) for the optical fibre based on said monitored temperature and used to generate (506) the acoustic sensitivity profile. The temperature profile indicates how well thermally coupled the fibre is to the surrounding cement, which also indicates how well acoustically coupled the fibre will be when the cement is cured. The sensitivity may be based on the rate of temperature change (303, 304) and/or magnitude of temperature change (T1, T2) during curing. The sensitivity profile can then be used to calibrate of adjust (604) measurement signals obtained using the optical fibre in a DAS sensor. The temperature during curing may be monitored using fibre optic distributed sensing such as DTS or DAS techniques.
    • 本申请涉及使用至少部分地嵌入在水泥结构(203)中的感测光纤(104)应用的光纤分布式声学感测(DAS),并且解决了在光纤的不同部分处的不同声学灵敏度的问题(203 )。 描述了一种产生声学灵敏度分布的方法,其涉及在围绕水泥结构固化期间沿着光纤的长度监测(501)温度。 然后可以基于所监视的温度为光纤产生温度分布(301,302)(502),并用于产生(506)声学灵敏度分布。 温度曲线表示纤维与周围水泥的热耦合程度,这也表明当水泥固化时纤维的声学耦合程度如何。 灵敏度可以基于固化期间温度变化率(303,304)和/或温度变化幅度(T1,T2)。 然后灵敏度分布可用于校准在DAS传感器中使用光纤获得的调整(604)测量信号。 可以使用诸如DTS或DAS技术的光纤分布式感测来监测固化期间的温度。
