    摘要: A valve assembly comprises a hot stab and a complementary connection block. The hot stab and the connection block are each provided with a pressure balanced rotating sleeve. When the hot stab is disconnected from the connection block, the rotating sleeve is in a closed position and fluid is not allowed to flow through the :hot stab. The rotating sleeve of the connection block is also in a closed position such that fluid is not allowed to flow through the connection block. The hot stab may be connected and disconnected to the connection block without reducing the fluid pressure.

    摘要: A downhole flow device has a sliding and ported sleeves. A seal has a first component on the sliding sleeve and a second component on the ported sleeve. These components engage one another to seal flow through the ports in the ported sleeve. The components move apart to allow fluid flow through the ports. The components are protected from abrasion and flow by virtue of the seal's structure and how it is opened. The sliding sleeve moves hydraulically along an axis of the ported sleeve to reveal successive ports defined along the sleeve's axis. Operation of the device and the seal address both erosion and damage from differential pressure problems. Thus, the seal prevent damage when unloading a differential pressure across it, and abrasive flow does not have the opportunity to impinge on the sealing surfaces to cause erosion.

    摘要: A stimulation tool includes a tubular having a port (114b); a first sleeve member (210b) disposed in the tubular and actuatable by an actuating member (802b) to move from a closed position wherein fluid communication between a bore of the tubular and the port is blocked; and a closure member (206a) disposed in the tubular and actuatable by the actuating member (802b) to a closed position wherein fluid communication through the bore of the tubular is blocked. A method of stimulating multiple zones of a tubular in a wellbore includes moving a sleeve member (210b) in the tubular by receiving an actuating member (802b) in the sleeve member (210b); releasing the actuating member (802b) from the sleeve member (210b); and actuating a closure member (206a) by receiving the released actuating member (802b) in a seat (217a).
