Seal failure assessment of a major gas field via integration of seal properties and leakage phenomena
Published 2020“…By analyzing the geometrical relationship between the leakage zone, the top-seal properties, and the gas–water contact, we conclude that the mode of leakage in this specific setting is not the result of gradual addition of gas charge but is instead consistent with a sudden increase of aquifer overpressure. We suggest two alternative models for seal failure in this case study: a conservative model consistent with a modest but rapid increase in aquifer overpressure leading to membrane seal failure and a model dominated by high aquifer overpressure leading to leakage through hydraulically dilated faults and fractures. …”

Gas explosion characteristics in confined straight and 90 degree bend pipes
Published 2015“…Based on the simulation analysis, the compression effect at the bending region and at the end of the pipe plays an important role to attenuate the burning rate, which resulting to a higher flame speeds and hence, increases the overpressure. Interestingly, a maximum overpressure of 14 barg with flame speed of 700 mis was observed in the smaller pipe of L/D=40 with acetylene fuel which indicated that the detonation-like event take place. …”
