Dear Gentelmen,

woud you please helping me to find these spe papres (about the estimation of the efficency of the hydraulic fracture).

10506-PA (A Fully Implicit Hydraulic Fracture Model).

10504-PA (Three-Dimensional Simulation of Hydraulic Fracturing)

117421-MS (Modeling of Hydraulically Fractured Wells in Full Field Reservoir Simulation Model).

119264-MS (A Simple and Accurate Model for Well Productivity for Hydraulically Fractured Wells)

And this one about the identification of downhole scale

68306-MS (Identification of Downhole Scales Using a Multi-Stage Stimulation Treatment)

Thank you in advance
