Publication number: 20240110471Abstract: A method for evaluating induced fractures in a wellbore includes obtaining a first set of data in a wellbore using a downhole logging tool. A first proppant is pumped into the wellbore, after the first set of data is captured. The first proppant includes a first tracer that is not radioactive. A second proppant is also pumped into the wellbore, after the first proppant is pumped into the wellbore. The second proppant includes a second tracer that is not radioactive, and the second tracer is different than the first tracer. A second set of data is obtained in the wellbore using the downhole tool after the first and second proppants are pumped into the wellbore. The first and second sets of data are compared.Type: ApplicationFiled: October 10, 2023Publication date: April 4, 2024Applicant: CARBO CERAMICS INC.Inventors: Jeremy ZHANG, Harry D. SMITH, Jr.

Publication number: 20240112673Abstract: Implementations described herein identify and correct automatic speech recognition (ASR) misrecognitions. For example, on-device processor(s) of a client device may generate a predicted textual segment that is predicted to correspond to spoken utterance of a user of the client device, and may receive further input that modifies the predicted textual segment to an alternate textual segment. Further, the on-device processor(s) may store these textual segments in on-device storage as a candidate correction pair, and transmit the candidate correction pair to a remote system. Moreover, remote processor(s) of the remote system may determine that the candidate correction pair is an actual correction pair, and may cause client devices to generate updates for a global ASR model for the candidate correction pair. Additionally, the remote processor(s) may distribute the global ASR model to the client devices and/or additional client devices.Type: ApplicationFiled: October 3, 2022Publication date: April 4, 2024Inventors: Rajiv Mathews, Rohit Prabhavalkar, Giovanni Motta, Mingqing Chen, Lillian Zhou, Dhruv Guliani, Harry Zhang, Trevor Strohman, Françoise Beaufays
