Uncertainty Estimation of Connected Vehicle Penetration Rate

Transportation Science, 2023
Knowledge of the connected vehicle (CV) penetration rate is crucial for realizing numerous beneficial applications during the prolonged transition period to full CV deployment. A recent study described a novel single-source data penetration rate estimator (SSDPRE) for estimating the CV penetration rate solely from CV data.

Rheology Design To Optimise Rate of Penetration

Proceedings of SPE/IADC Drilling Conference, 1996
Abstract A Bit Reynolds Number optimization algorithm has been developed in response to the field observation that this maximizes the rate of penetration regarding bit hydraulic effects. Discussion on the reasons for such behaviour are undertaken and some common drilling scenarios are presented for which Bit Reynolds ...

Increased Rate of Penetration Through Automation

SPE/IADC Drilling Conference and Exhibition, 2011
Abstract Drilling lags behind other industries in the implementation of automation. One reason for this is the variability of drilling operations and uncertainty in knowing what is being drilled at any given time. A closed-loop system that continually monitors drilling parameters and drilling performance in real time and constantly ...
