... handling hydrogen can have higher failure frequencies compared to those handling natural gas. These factors must be taken into account when considering the establishment of a hydrogen distribution network throughout Europe, where safety distance between parallel pipelines and population shall be granted...

... in the frequency domain. Pulses that are not sinusoidal in shape contain multiple frequency components and when the response is linear, these components can be isolated and interpreted. If the coverage of frequencies is sufficient, an analysis similar to well test analysis can be performed and reservoir properties...

Abstract I have processed a total of nine thousand microseismic events to investigate the stochastic process of the stress mechanism as well as frequency-magnitude relation between microseismic, volcanic and intraplate events. The processed data was composed of all available three components...

... will protect the whole system and this extra protection may offset the extra volume of chemical necessary. The application of SI in injector well was studied in both continuous and batch mode with different injection frequencies. It was shown in continuous injection that even though less SI volume is used...

Thus no interruption of well and reservoir production is needed before and during the test. If the pulsed pressure and rate signal analysis is performed in the frequency domain, a strong similarity exists...

... but also simulates results after making adjustments in control variables, such as tubing head pressure (THP) and pump frequency. Changing THP and frequency lets users model production to predict and circumvent negative well pump events. This project was implemented in a mature carbonate oil reservoir...

... Abstract Harmonic pulse testing is a well testing technique in which the injection or production rate is varied in a periodic way. The pressure response to the imposed rates, both in the pulser well and in the observer wells, can be analyzed in the frequency domain to evaluate the reservoir...
