Single trip method for selectively fracture packing multiple formations traversed by a wellbore

A single trip method for fracturing multiple formations traversed by a wellbore comprising the steps of:

• locating a first screen assembly having a plurality of first valves within the wellbore proximate a first formation;
• locating a second screen assembly having a plurality of second valves within the wellbore proximate a second formation;
• operably positioning a service tool proximate the first formation;
• injecting a first fracture treatment fluid through the service tool into of the first screen assembly;
• progressively operating the first valves in response to pressure within the first screen assembly to establish fluid communication from the interior to the exterior of the first screen assembly to progressively fracture the first formation;
• repositioning the service tool proximate the second formation;
• injecting a second fracture treatment fluid into the interior of the second screen assembly;
• and
• progressively operating the second valves in response to pressure within the second screen assembly to establish fluid communication from the interior to the exterior of the second screen assembly to progressively fracture the second formation.
