Abstract
The present invention includes systems and methods for continuous fracturing operations across a multichannel fracturing configuration. To swap a first well for a second well while continuously pumping water and/or frac fluid through the fracturing system, the second well may be initially prepared through a pressure equalization process. Once the second well is equalized and open, the first well may be sequentially closed and depressurized. Thus, the first well is swapped for the second well while the water and/or frac fluid continuously flows through the system. A conditional flow control valve may be used to sequentially open and/or close the flow of frac fluid through the frac manifold.
Claims19
A method for operation of a multichannel fracturing operation that includes at least a first well and a second well comprising:
- supplying a frac fluid to the first well at a first treating fluid pressure, wherein at least one first control valve at a first frac manifold is open during the supplying step;
- opening a second control valve at a second frac manifold while the frac fluid is being supplied to the first well at said first treating fluid pressure wherein at least a portion of the frac fluid from the first treating fluid pressure is supplied to said second well;
- observing a fluid pressure at the first control valve after the frac fluid is supplied to said second well;
- closing the at least one first control valve at the first frac manifold by transitioning to a partially closed state and then to a fully closed state in response to said fluid pressure observations at the at least one first control valve to stop the flow of frac fluid to said first well, wherein the frac fluid is then being supplied to the second well at a second treating fluid pressure;
- and
- opening a third control valve at a third frac manifold for a third well while the frac fluid is being supplied to the second well at the second treating fluid pressure wherein at least a portion of the frac fluid from the second treating fluid pressure is supplied to a third control valve while the first control valve remains fully closed.
A method for operation of a multichannel fracturing operation with a first well and a second well comprising:
- supplying a frac fluid to the first well at a first treating fluid pressure, wherein at least one first control valve at a first frac manifold is open during the supplying step;
- opening a second control valve at a second frac manifold while said frac fluid is being supplied to the first well at said first treating fluid pressure wherein at least a portion of the frac fluid from the first treating fluid pressure is supplied to the second well;
- observing a fluid pressure at the first control valve after the at least a portion of the frac fluid is supplied to the second well;
- adjusting the at least one first control valve at the first frac manifold by transitioning to a partially closed state in response to a first fluid pressure reading at the at least one first control valve;
- closing the at least one first control valve to stop the flow of frac fluid to the first well in response to a second fluid pressure reading, wherein the frac fluid is then being supplied to the second well at a second treating fluid pressure;
- and
- adjusting at least one master valve of a first frac tree and bleeding off pressure from the first well after said closing step.
A non-transitory computer readable medium with computer executable instructions stored thereon executed by a processor to perform a method for continuous operation of a multichannel fracturing operation that includes at least a first well, and a second well, said method comprising:
- supplying a frac fluid to the first well at a first treating fluid pressure, wherein at least one first control valve at a first frac manifold is open during said supplying step;
- opening a second control valve at a second frac manifold while said frac fluid is being supplied to the first well at said first treating fluid pressure wherein said frac fluid from the first treating fluid pressure is supplied to said second well;
- observing a fluid pressure at said first control valve after said frac fluid is supplied to said second well;
- adjusting the at least one first control valve at the first frac manifold by transitioning to a partially closed state in response to a first fluid pressure reading at the at least one first control valve;
- closing the at least one first control valve to stop the flow of frac fluid to said first well in response to a second fluid pressure reading, wherein the frac fluid is then being supplied to the second well at a second treating fluid pressure;
- and
- opening a third control valve at a third frac manifold for a third well while the frac fluid is being supplied to the second well at the second treating fluid pressure wherein at least a portion of the frac fluid from the second treating fluid pressure is supplied to a third control valve while the first control valve remains fully closed.
