  • Accoustic triggering devices for multiple fluid samplers and methods of making and using same
    Patent number: 9708909
    Abstract: A method for capturing a sample from a wellbore, comprising the steps of introducing a first message and a second message into a tubing positioned within the wellbore. The first message is directed to a first modem connected to a first sampler device to cause the first sampler device to collect a first sample. The second message is directed to a second modem connected to a second sampler device to cause the second sampler device to collect a second sample.
