Claim 11:
12. A method for swapping a first well for a second well in a multichannel fracturing operation, wherein said multichannel fracturing operation comprises a first well site comprising a first frac tree and a first frac manifold that are fluidly connected to be configured to supply frac fluid to said first well, and a second well site comprising a second frac tree and a second frac manifold that are fluidly connected to be configured to supply frac fluid to said second well, said method comprising:
creating a pressure at a second frac manifold, where a first conditional control valve at said second frac manifold is first partially opened and then closed during said creating step to hold a fluid pressure at said first conditional control valve, wherein said first conditional control valve is then reopened to enable said frac fluid to be supplied to said second well;
incrementally closing at least one second conditional flow control valve at said first frac manifold while said frac fluid is being supplied to said second well; and
closing at least one master valve at said first frac tree wherein said frac fluid is no longer supplied to said first well.
