Abstract

Apparatus and methods for providing fluid and projectiles to downhole tubulars includes a manifold. The manifold may include a housing, a cartridge disposed within the housing, and an actuator. The cartridge includes multiple throughbores for selectively allowing a fluid flow to pass through, and storing a projectile. The actuator is adapted to move the multiple throughbores of the cartridge out of and into the fluid flow to release the stored projectile into the fluid flow. The manifold may include multiple projectiles that are stored laterally relative to each other for radial translation and release into the fluid flow.
