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: Combined wireline and wireless apparatus and related methods are disclosed herein. An example apparatus includes a tool string including a tool bus and a first acoustic repeater coupled to the tool string. The first acoustic repeater is to communicate with a second acoustic repeater to exchange data. The second acoustic repeater is communicatively coupled to a first tool. The first tool is not communicatively coupled to the tool bus.

Abstract: A network management system for a wireless communications network adaptively selects wireless modems to use in communicating messages between a control system and downhole equipment. The wireless modems are selected based on a monitored signal to noise ratio. The network management system may be centralized within the network or within a surface control system or can be decentralized so that a plurality of the wireless modems can adaptively determine routing in the network. The network management systems can be used in conjunction with a backbone network architecture to achieve further efficiencies in network throughput.

Abstract: An acoustic communications network includes acoustic modems that exchange messages on an acoustic communications medium, such as tubing deployed in a wellbore. The acoustic communications medium is characterized by an acoustic transfer function having a plurality of passbands and a plurality of stopbands. The messages are communicated by encoding the message into a plurality of symbols representing the message and distributing the plurality of symbols across a bandwidth of a wideband acoustic signal that spans at least one passband and at least one stopband of the acoustic transfer function.
