ABSTRACT:
A proppant containment apparatus and associated method of using the apparatus permit continued delivery of a proppant slurry to a subterranean wellbore after failure of a crossover portion of the apparatus during a fracturing operation, eliminating the need to stop the fracturing operation and remove and replace expensive items of equipment after such crossover failure. In a preferred embodiment, the proppant containment apparatus has a tubular crossover member with an internal flow passage, circulation port, and side wall outlet openings, first and second coaxial tubular structures, the first tubular structure being perforated, a tubular screen positioned between the first and second tubular structures, a ball, and a ball seat having a spaced series of grooves formed thereon.
