Abstract
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.
