Abstract
The present invention relates to a well-bore sensor apparatus and method. The apparatus includes a downhole tool carrying at least one sensor plug for deployment into the sidewall of a well-bore. The apparatus may also be used in conjunction with a surface control unit and a communication link for operatively coupling the sensor plug to the surface control unit. The sensor plug is capable of collecting well-bore data, such as pressure or temperature, and communicating the data uphole via a communication link, such as the downhole tool or an antenna. The downhole data may then be analyzed and control commands sent in response thereto. The sensor plug and/or the downhole tool may be made to respond to such control commands. In some embodiments, multiple surface control units for corresponding wells may be networked for decision making and control across multiple well-bores.
