Abstract: Systems and methods for monitoring a position of a service tool in a wellbore are provided. The service tool can have a sensor assembly coupled thereto and be positioned within the wellbore. The service tool can be moved within the wellbore. The distance travelled by the service tool in the wellbore can be measured with the sensor assembly. The position of the service tool in the wellbore can be determined by comparing the distance travelled to a stationary reference point.

Abstract: A technique facilitates detection of an event in a subterranean environment, e.g. in a wellbore. A tool may be deployed to a desired wellbore location or other subterranean location for actuation between operational positions. An acoustic system also is deployed to detect a unique acoustic signature associated with an event related to operation of the tool. Upon detection of the unique acoustic signature, the acoustic system transmits data to a surface location or other suitable location to indicate occurrence of the event. An example of such an event is transition of the tool between operational positions.
Abstract translation: 一种技术有助于检测地下环境中的事件，例如。 在井筒里 可以将工具部署到期望的井眼位置或其他地下位置，以在操作位置之间进行操作。 声学系统也被部署以检测与与工具的操作有关的事件相关联的独特的声学签名。 在检测到独特的声学签名之后，声学系统将数据传输到表面位置或其他合适位置以指示事件的发生。 这种事件的一个例子是工具在操作位置之间的转换。
