摘要： Objects are monitored in a subterranean well. A well system can include at least one object having a transmitter, and at least one sensing device which monitors displacement of the object along a wellbore. A method of monitoring at least one object in a subterranean well can include positioning at least one sensing device in a wellbore of the well, and then displacing the object through the wellbore, the sensing device monitoring the object as it displaces through the wellbore.

摘要： Distributed density, temperature and/or strain sensing is utilized for downhole monitoring. A method and system for monitoring a rapidly changing parameter in a well includes: detecting gain-based stimulated Brillouin backscattering due to light transmitted through at least one optical waveguide installed in the well, the Brillouin backscattering being dependent upon temperature and strain experienced by the waveguide in the well. The method can include measuring at least one of temperature and strain in the well, with the measurement being performed separately from the step of detecting Brillouin backscattering.

摘要： Distributed acoustic, vibration, density and/or strain sensing is utilized for downhole monitoring. A method of tracking fluid movement along a wellbore of a well includes: detecting vibration, density, strain (static and/or dynamic) and/or Brillouin frequency shift in the well using at least one optical waveguide installed in the well; and determining the fluid movement based on the detected vibration, density, strain and/or Brillouin frequency shift. Another method of tracking fluid movement along a wellbore of a well includes: detecting a change in density of an optical waveguide in the well; and determining the fluid movement based on the detected density change.
