A multiple pocket mandrel for use in a well tubing having fluid bypass passageways in parallel with the pockets for increasing the fluid flow area through the mandrel. Preferably, the pockets are equally spaced about a central open bore of the mandrel and a fluid passageway is positioned between adjacent pockets. The mandrel may include an orienting sleeve about the open bore above the pockets with a second set of fluid passageways offset from the open bore for providing fluid bypass passageways around the orienting sleeve.

Multiple pocket mandrel with fluid bypass

A mandrel for use in a well tubing in which the mandrel body has an open bore for alignment with the well tubing and a sidepocket offset from the open bore for receiving flow control devices. An integrally forged sub is welded to the top of the body and includes an actuating shoulder angularly spaced from the axis of the offset pocket a predetermined amount and a guide surface is positioned below the shoulder and directed upwardly towards the shoulder. A deflector guide is positioned in the offset bore above the pocket and includes a pair of rails forming a guide path which allows the entrance of flow control devices in the pocket but prevents the entrance of open bore tools into the guide path. The deflector guide and the pocket are telescopically secured to each other by coacting flat surfaces for insuring transverse alignment therebetween and include abutting coacting shoulders for maintaining proper axial spacing between the locking lug and the pocket.
