Abstract: Inversion-based workflows are provided for real-time interpretation of the electromagnetic (EM) look-around and look-ahead measurements. The profile of a look-around zone is determined by interpreting EM measurements of a look-around zone. The profile of the look-around zone characterizes formation dip as well as vertical resistivity or resistivity anisotropy of one or more formation layers of the look-around zone. The profile of a look-ahead zone is determined by interpreting EM measurements of the look-ahead zone. The profile of the look-ahead zone characterizes formation dip as well as horizontal resistivity, vertical resistivity or anisotropy of one or more formation layers of the look-ahead zone. The workflows can also involve interpretation of look-around resistivity measurements to aid in the characterization of the look-around zone.

Abstract: A method for collecting data of a consumption, a physical or physico-chemical parameter and/or an operating state in a supply network for consumables. A measuring element of a local sensor provides elementary measuring units, which correspond to at least one physical or physico-chemical variable or at least one physical or physico-chemical parameter, as raw measurement data. In order to determine the measurement resolution of the sensor, the conditions for generating time stamps are determined in advance using a correlation model, time stamps of successive raw measurement data are generated in the sensor on the basis of the correlation model, and the time stamps are transmitted via a wired connection and/or via a radio path. The raw measurement data are reconstructed and evaluated based on the time stamps with the correlation model. The conditions for generating time stamps can be changed dynamically within the framework of the correlation model.

Wherein operating state monitoring of the sensor is carried out by comparing current time stamps with historical and/or empirical time stamps.
