Patent attributes
Fracturing headers and connected conduits are fit with one or more fluid screening and wear minimizing inserts. Tubular screen inserts are provided to screen a flow of fracturing fluid through manifolds prior to, or at, the fracturing header. Each tubular screen insert has a tubular wall having an insert bore, an endwall and an open inlet. A plurality of openings, about the tubular wall, provide fluid communication between the bore and an annular area outside the wall. Oriented in a flow conduit with the closed endwall upstream, the insert excludes and sheds debris therefrom. Oriented with the closed endwall downstream, the insert receives and stores debris. Pairs of inserts, retained in opposing inlet ports, serve to screen fluid and deflect erosive flow from tools such as coil tubing extending therethrough. A fracturing block fit with opposing inlet ports can also be fit with an outlet port for flowback operations.
