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.
Claims41
A system for acquiring at least one sample from a fluid, the system comprising:
- one or more devices;
- each device including a sampling mechanism having:
- an isolated cavity that is initially inaccessible to the external fluid;
- an electrically passive timing mechanism including a piercing structure;
- and
- a mechanical structure separating the isolated cavity from the exterior environment, wherein at the end of a timing interval the piercing structure of the timing mechanism pierces the mechanical structure, bringing the isolated cavity in contact with the external fluid.
A method for acquiring at least one sample from a fluid, the method comprising:
- deploying at least one device in the fluid;
- each device including a sampling mechanism having:
- an isolated cavity that is initially inaccessible to the external fluid;
- an electrically passive timing mechanism including a piercing structure;
- and
- a mechanical structure separating the isolated cavity from the exterior environment, wherein at the end of a timing interval the piercing structure of the timing mechanism pierces the mechanical structure, bringing the isolated cavity in contact with the external fluid.
