Claim Text:
1. A method for completing a wellbore in a subsurface formation, the method comprising: providing a packer, the packer comprising: connecting the packer to a tubular body; running the packer and connected tubular body into the wellbore; running a setting tool into the inner mandrel of the packer; manipulating the setting tool to mechanically release the movable piston housing from its retained position; setting the packer by communicating hydrostatic pressure to the piston housing through the one or more flow ports, thereby moving the released piston housing to actuate the sealing element into engagement with the surrounding wellbore; injecting a gravel slurry into an annular region formed between the tubular body and the surrounding wellbore; and injecting the gravel slurry through the alternate flow channels to allow the gravel slurry to at least partially bypass the sealing element so that the wellbore is gravel-packed within the annular region below the packer.
