Abstract: A mobile communication device for receiving an ad hoc temporary upgrade in quality of service (QoS). The mobile communication device comprises a processor, at least one cellular radio transceiver, a non-transitory memory, and an ad hoc service upgrade application. When executed by the processor, the application monitors wireless cellular communication on a network via the at least one cellular radio transceiver, detects a significant delay in the communication, generates a prompt on a GUI, the prompt comprising a plurality of options for an ad hoc temporary upgraded QoS, where each option is associated with a time period. The application further, based on a user input, requests a preferred roaming list (PRL) associated with the temporary upgraded QoS, receives the PRL, wherein the PRL is associated with providing the upgraded QoS on an allocated spectrum, activates the received PRL, and upon expiration of the time period, deactivates the received PRL.

Abstract: The present disclosure provides a method of processing data obtained from distributed optical fiber sensors to detect acoustic energy generated by a poroelastic effect of fractures in a structure, such as a rock formation. The sensing fiber of an optical fiber distributed sensing system may be deployed in the vicinity of the region where fracturing is occurring, for example, along a well that is offset from a treatment well undergoing hydraulic fracturing. The DAS data obtained from along the sensing fiber is processed to measure changes in the low-frequency strain caused by the poroelastic effects in the rock as the fractures open and close. This measured strain rate data is iteratively processed at each instant time to identify fracture opening features (characterised as compression-tension-compression) that are correlated with fracture closing features (characterised as tension-compression-tension) as a function of depth, to thereby identify and locate fracture hits in the vicinity of the sensing fiber.
