Abstract
An electrically passive device and method for in-situ acoustic emission, and/or releasing, sampling and/or measuring of a fluid or various material(s) is provided. The device may provide a robust timing mechanism to release, sample and/or perform measurements on a predefined schedule, and, in various embodiments, emits an acoustic signal sequence(s) that may be used for triangulation of the device position within, for example, a hydrocarbon reservoir or a living body.
Claims53
A system for acquiring samples in a body of fluid, the system comprising:
- a containment unit that is negatively buoyant relative to the body of fluid;
- a sampling array tethered to the containment unit, the sampling array including a plurality of sampling devices, each sampling device including a sample chamber for storing an acquired sample, the plurality of sampling devices for storing samples of the body of fluid at varying depths;
- and
- a release that releasably holds the tethered sampling array in an initial position relative to the containment unit,
- wherein upon activation, the release allows the sampling array, still tethered to the containment unit at a first end, to ascend in the body of fluid with the sampling devices spaced along the length of the array.
A method for acquiring samples in a body of fluid, the method comprising:
- installing in the body of fluid a containment unit negatively buoyant relative to the body of fluid, a sampling array tethered to the containment unit, the sampling array including a plurality of sampling devices spaced along the length of the array, each sampling device including a sample chamber for storing an acquired sample, the plurality of sampling devices for storing samples of the body of fluid at varying depths.
A system for acquiring samples in a body of fluid, the system comprising:
- a containment unit that is negatively buoyant relative to the body of fluid;
- a sampling array tethered to the containment unit, the sampling array including a plurality of sampling devices, each sampling device including a sample chamber for storing an acquired sample, the plurality of sampling devices for storing samples of the body of fluid at varying depths,
- wherein the sampling array includes an accelerometer, a tiltmeter, a gyroscope, relative bearing device, an inclinometer, a compass, or a GPS system, or any combination thereof, for providing position information of the sampling array relative to the containment unit.
A method for acquiring samples in a body of fluid, the method comprising:
