Abstract: A technique facilitates stimulation of multiple well zones along a multilayered reservoir. The technique utilizes equipment constructed to enable performance of the stimulation job along the multiple well zones, i.e. two or more well zones, prior to gravel packing the multiple well zones. The equipment enables performance of the stimulation job during a single trip downhole. Subsequent actuation of the equipment further enables a multizone gravel packaging operation during the same trip downhole.

Abstract: A method of completing a well in a single trip includes drilling a well-bore with drilling mud, miming a single trip completion string including an upper completion, a lower completion, and a packer between the upper and lower completions into the wellbore, displacing the wellbore to solids free fluid by opening or closing a circulation sliding sleeve disposed below the packer in the lower completion, opening the circulation sliding sleeve and spotting gravel slurry in a casing annulus, closing the circulation sliding sleeve and pumping the gravel slurry down the casing annulus into an open hole annulus while taking returns through a base pipe of a sand control assembly and production tubing of the single trip completion string, opening the circulation sliding sleeve, displacing the cased hole section to completion fluid, closing the circulation sliding sleeve, and setting the packer.

Abstract: A seal assembly sealingly engages a packer that is retrievable from the packer. The seal assembly comprises a sealing structure for receiving by a seal bore of the packer, and a housing assembly defining an inner chamber and having at least one control line conduit and at least one flow conduit passage. The seal assembly further comprises at least one control line extending through the control line conduit into the inner chamber, and at least one flow conduit extending through the flow conduit passage into the inner chamber.
