The value is closely related to size and position of leak point, leakage rate, height of annular protective liquid, length of gas column at wellhead and the state of CO2.
The ultrasonic signals excited by the leakage are collected by the contact-coupled piezoelectric ultrasonic sensor array, afterward, the time-space matrix of the leakage signal is calculated, and through analyzing the matrix, the position of the leakage hole can be obtained.
The position of a hydrate plugging or leakage can be achieved by correlation algorithm.
"The positioning of the plug and potential sources of leakage all come into play in considering how to use these things," Dr. Fortune said.
The stomach was irrigated with saline, and EUS scanning was used to confirm the position of the stent and rule out further leakage.
There will be plenty of leakage".
Not to mention the possibility of leakage.
"Tolerating a certain amount of leakage pays off.
A spokesman for the trade body Water UK, which represents the 21 water companies, said: "Water companies take leakage and their customers' views of leakage extremely seriously.
"There's a lot of leakage," said John Ferber, co-founder of AdBroadcast.
Anything present within the "zone" of leakage begins to crystallise: to reiterate itself as pure structure.
