ABSTRACT This paper presents the results of an analytical study of hydraulic fracture initiation and propagation from deviated wellbores. The interaction and link-up of the starter fractures initiated from perforations and the turning of the linked fracture are investigated. A criterion that correlates fracture link-up to stresses and wellbore parameters is established. The characters of the near-wellbore multiple fractures and their effects on fracture width reduction and friction loss are also studied. The model-predicted pressure response, which takes into account the near-wellbore friction loss, is compared to the measured bottom hole pressure data during a fracture treatment.
