Cemented multi-stage sleeves improve fracture-stimulation efficiency ///

To economically develop unconventional resource plays, such as the Eagle Ford shale in South Texas, multiple, complex hydraulic fracturing stages must be executed in the horizontal section of the wellbore. Traditionally, a plug-and-perforate (P-n-P) process has been used. However, inherent difficulties in the process often limited completion cycle time and created barriers to economic delivery of the hydraulic fracturing treatment.
