Abstract: Systems and methods for estimating tool string depth can include a framework that utilizes machine learning to determine depth and depth uncertainties for the tool string. The framework can take as inputs a casing collar locator signal, a depth, a cable speed, and a timestamp. Then a collar detector function, which can be a machine learning model, can detect a collar and output a certainty level associated with the detection. A collar identifier function can combine that certainty level with a prior collar map and other prior parameters to identify a particular collar and that collar's depth. Then a fusion function can output a depth and depth uncertainty for the collar or for the tool string.

Abstract: A system and method to automate data acquisition in a wireless telemetry network optimizes data acquisition to best match a target data set that the user desires given the performance limitations of the telemetry network. The user defines the target data set by providing inputs regarding a target quality of the target data set relative to a data set that has been produced and stored by a communication node in the network. The performance limitations of the network are defined in a system operating envelope. A data acquisition cycle is then automatically initiated and propagated in the network to acquire an actual data set that is an optimal match for the user's target given the system operating envelope.

Abstract: An acoustic network is located in a formation traversed by a borehole having a pipe contained therein. The acoustic network includes a backbone network having a number of backbone modems engaging the pipe and acoustically communicating along the pipe using a first modulation technique. A number of end node modems acoustically communicate using a second modulation technique orthogonal to the first modulation technique. At least one of the backbone modems is a bridge hub modem that is coupled to both the backbone network and an end node modem and communicates with the backbone network using the first modulation technique and with the end node modem using the second modulation technique. The end node modems may have a hibernation mode defined by low energy usage with no transmission or receipt of data, and a transmission mode defined by transmission of data by the end node modem.

Abstract: A network management technique for an acoustic communication system made up of a network of communication nodes is disclosed. Various of the nodes that are located intermediate a source node and a receiving node can detect communication failures in the network and then take action to efficiently recover from the failure, rather than acting only as repeaters. By allowing intermediate nodes to participate in recovery decisions, the speed and the quantity of real-time information transmission in the network can be improved.
