Abstract: Disclosed herein are methods and system for redistributing bulk material across a geographical area. A method for providing bulk material for a wellbore operation, the method comprising: forming a logistical model database to determine bulk material required for an at least one wellsite located in a geographical area; acquiring bulk material from a distribution center; verifying the bulk material acquired; and transporting bulk material for the wellbore operation. A method for providing bulk material for a wellbore operation, the method comprising: determining demand for bulk material across a geographical area; collecting data throughout a life cycle of bulk material; transmitting collected data to an off-site network comprising an adaptive machine; analyzing collected data via the off-site network thereby producing an output; providing bulk material to a wellsite based on output.

Abstract: A method includes monitoring work done by a piece of equipment to generate backward-looking usage data. The method includes making a prediction of future work to be done by the piece of equipment, generating forward-looking usage data based on the prediction of future work, and making a prediction of when the piece of equipment is expected to fail based on the backward-looking usage data and on the forward-looking usage data. The method includes operating the piece of equipment after performing the prediction, and removing the piece of equipment from service prior to when the piece of equipment is expected to fail based on the prediction.
