Methods and systems for determining caving volume estimations based on logging data and geomechanical models are provided. For example, a system can receive image log data measured during a drilling operation in a wellbore. The system can receive an identification of a breakout in a subterranean formation around the wellbore. The system can determine, using the image log data, a breakout angular width for the breakout. The system can determine a breakout depth for the breakout. The system can determine a caving volume based on the breakout depth and the breakout angular width substantially contemporaneously with the drilling operation. The system can output the caving volume estimation for use in substantially contemporaneously adjusting a drilling parameter for the drilling operation.

A system for processing delivery items, the system including a delivery item monitoring device comprising one or more sensor and a processor that is communicatively connected to the delivery item monitoring device and that is configured to perform operations comprising obtaining sensor data from the one or more sensor. The operations can also include calculating a depth of the received delivery items in the container based on the sensor data and generating an under-filled indicator, a transport indicator, or an over-filled indicator based on the depth of the received delivery items in the container. Furthermore, the operations can include transmitting the under-filled indicator, the transport indicator, or the over-filled indicator to a control system, wherein the under-filled indicator, the transport indicator, and the over-filled indicator designate how to process the container to the control system.
