发明名称 Zonal contact with cementing and fracture treatment in one trip
摘要 Systems and methods for fracturing multiple zones in a wellbore are provided. Cement can be pumped through a work string into a first annulus formed between a liner and a wall of the wellbore. One or more first contact valves in the liner can be opened with the work string. Fluid can flow through the work string and the one or more first contact valves to fracture a first zone. One or more second contact valves in the liner can be opened with the work string. Fluid can flow through the work string and the one or more second contact valves to fracture a second zone.

主权项 1. A method for fracturing multiple zones in a wellbore, comprising: running a work string into a liner that is positioned in the wellbore, wherein a first annulus is formed between the liner and a wall of the wellbore; pumping cement through the work string into the first annulus; opening one or more first contact valves in the liner with the work string, wherein the one or more first contact valves are disposed proximate a first zone of the wellbore; flowing a fluid through the work string and the one or more first contact valves to fracture the first zone; opening one or more second contact valves in the liner with the work string, wherein the one or more second contact valves are disposed proximate a second zone of the wellbore; and flowing the fluid through the work string and the one or more second contact valves to fracture the second zone, wherein, in a single trip of the work string in the wellbore: the cement is pumped into the first annulus,the first zone is fractured, andthe second zone is fractured.
