Abstract
This paper discusses the use of numerical simulations for predicting
the onset, development, and post stage of fracture tip screenout (TSO),
with particular application to Frac Pack stimulations. It also presents
the application of TSO for fracture containment to prevent height growth
into water boundaries or into gas cap formations, under Gulf of Mexico
reservoir conditions (soft formations with high permeability and high
leakoff). Two typical field cases are analyzed to demonstrate different
phenomena.
