Multiple well treatment fluid distribution and control system and method

Abstract

A system for distributing fluid to a plurality of wellbores drilled from a common pad includes at least two fluid conduits extending between the wellbores. The fluid conduits are configured to couple at one end to a fluid pump. At least one remotely operable valve is hydraulically connected to each fluid conduit proximate each wellbore. At least one flow line hydraulically connects each remotely operable valve to each wellbore such that fluid moved through the flow line enters the wellbore. A control unit is disposed proximate the pad and is configured to operate the remotely operable valves.

1 . A system for distributing fluid to a plurality of wellbores drilled from a common pad, comprising:
 at least two fluid conduits extending between the wellbores, the fluid conduits configured to couple at one end to at least one fluid pump;   at least one remotely operable valve hydraulically connected to each fluid conduit proximate each wellbore;   at least one flow line hydraulically connecting each remotely operable valve to each wellbore such that fluid moved through the flow line enters the wellbore; and   a control unit disposed proximate the pad and configured to operate the remotely operable valves.   
     
     
         2 . The system of  claim 1  further comprising a valve at one end of each fluid conduit. 
     
     
         3 . The system of  claim 1  further comprising at least one erosion sensor disposed at a selected position along each fluid conduit, the at least one erosion sensor in signal communication with the control unit. 
     
     
         4 . The system of  claim 1  further comprising at least one erosion sensor disposed at a selected position along each flow line, the at least one erosion sensor in signal communication with the control unit. 
     
     
         5 . The system of  claim 1  further comprising a flow rate sensor disposed in each flow line, the flow rate sensors in signal communication with the control unit. 
     
     
         6 . The system of  claim 1  further comprising at least one additional valve in each flow line disposed between the at least one remotely operable valve and the wellbore. 
     
     
         7 . The system of  claim 1  wherein the at least one additional valve is remotely operable. 
     
     
         8 . A method for operating a plurality of wellbores drilled from a common pad, wherein the wellbores include at least two fluid conduits extending between the wellbores, the fluid conduits configured to couple at one end to a fluid pump; at least one remotely operable valve hydraulically connected to each fluid conduit proximate each wellbore, a flow line hydraulically connecting each remotely operable valve to each wellbore such that fluid moved through the flow line enters the wellbore, and a control unit disposed proximate the pad and configured to operate the remotely operable valves, the method comprising:
 moving a wellbore intervention device to a selected one of the wellbores;   communicating a signal from the control unit to close the remotely operable valves associated with the selected wellbore;   inserting at least one wellbore instrument into the selected one of the wellbores using the intervention device;   communicating a signal from the control unit to open at least one of the remotely operable valves at least one other wellbore; and   pumping fluid into ones of the at least two conduits associated with the opened remotely operable valves such that fluid enters the at least one other wellbore.   
     
     
         9 . The method of  claim 8  wherein the fluid is hydraulic fracturing fluid.
