ABSTRACT:
A proppant slurry screen apparatus and associated method of using it prevent sticking of a service tool during proppant slurry delivery to a subterranean wellbore after failure of a crossover portion of the apparatus. In a preferred embodiment, a proppant slurry screen 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 extending above a packer and having a radial port which provides fluid communication between the wellbore above the packer and an annular flow passage between the first and second tubular structures, and a tubular screen positioned between the first and second tubular structures adjacent the port and operative to screen proppant from the proppant slurry.
