Abstract
A straddle packer has a multicomponent mandrel with an active mandrel component. A pressure cylinder module reciprocates in opposite directions within a limited range over the active mandrel component. When fluid is pumped through a tubing string into the straddle packer, a piston of the pressure cylinder module is urged in one direction along an axis of the active mandrel component while a cylinder wall of the pressure cylinder module is urged in an opposite direction along the axis to simultaneously compress spaced-apart packers of the straddle packer to a packer set condition.
