Abstract
There are described devices and methods for use, for example, with signaling in a well, e.g. using a well structure of the well. Such signaling may include the communication of power and/or data signals. The devices and methods used may assist with efficient and/or effective communication of such signals. In some examples, there is described deployable devices and methods, e.g. a deployable device for signaling contact in a well, and methods associated therewith.
Claims7
A method for communicating electrical signals in a well, the method comprising:
- deploying an electrical contact device to a location in a well, the well having a metallic well structure;
- controllably deploying a mounting arrangement of the electrical contact device so as to mechanically and electrically engage with a wall surface of the metallic well structure;
- and
- communicating electrical signals to and/or from the metallic well structure using an electrical signal path formed between the electrical contact device and the metallic well structure, using the mounting arrangement.
