Abstract: The present invention addresses to a real-time flow assurance occurrence monitoring system with the aim of reducing oil production losses caused by occurrences in the flow assurance area, which uses a web tool to integrate results of simulations of multiphase flow and thermodynamic simulators with production data and specific correlations, developed to monitor the formation of deposits or blockages in subsea lines. This tool has the specific objective of monitoring the formation of hydrates, paraffins and emulsions in real time and other occurrences that may cause a production shutdown. Based on this information, it issues an alert of the occurrence in the control rooms of the operational units, supporting decision-making on operational procedures that must be carried out to avoid the loss of oil production. It further records the operations carried out to mitigate occurrences. All data is structured in tables and graphs and can be exported to other systems.

Abstract: Self-calibrating a humidity sensor of an integrated humidity and temperature sensor, using the integrated heating element, and the temperature and humidity sensors, of the device, together with a firmware-based control loop running on a controller. The controller actively calculates and monitors one or both sensor output, and the slopes of the sensor outputs, in real time, while the heating element is on, and compares one or both slopes to a pre-programmed threshold, while in a programmable control loop, to then capture the appropriate relative humidity offset to apply to the device during normal operation (with the integrated heating element switched off) for correcting the relative humidity output from the device. Any singularly mounted in-system device can be calibrated, independent of external references, for in-system calibration.

Abstract: A method for providing an enhanced estimate of reference barometric pressure. The method uses multiple, dissimilar pressure references, such as in airport weather stations, personal weather stations, and wireless terminals such as smartphones, in order to provide the enhanced estimate of reference barometric pressure. The method generates an enhanced estimate of reference barometric pressure based on a first estimate of reference barometric pressure from a first pressure reference network made up of airport weather stations, for example. The method also uses a second estimate of reference barometric pressure from a second pressure reference network made of up personal weather stations, for example, and a third estimate of reference barometric pressure, also from the second network. The first, second, and third estimates of reference barometric pressure are combined such that both measurement accuracy and timeliness are improved in the resulting, enhanced estimate.
