Abstract: A technique facilitates servicing of a subterranean formation by treating a specific section of a well. The technique utilizes a straddle packer conveyed downhole and then activated via coiled tubing. The straddle packer comprises a first, e.g. upper, packer and a second, e.g. lower, packer which are deployed downhole into the wellbore to the specific section of the wellbore proximate a target formation zone. Once properly located, the straddle packer is uniquely activated by compression and tension inputs applied via the coiled tubing.

Abstract: A blow out preventer includes a blow out preventer body, at least one pipe ram disposed in the blow out preventer body which opens or closes in at least one respective cavity defined by the blow out preventer body, an inverted pipe ram disposed in the blow out preventer body which opens or closes in a respective cavity defined by the blow out preventer body, and a pressure management system for adjusting pressure within the blow out preventer below damaging pressure levels as one or more of the at least one pipe ram and the inverted pipe ram open or close in a respective cavity. In some cases, a second pipe ram disposed in the blow out preventer body which opens or closes in a respective cavity defined by the blow out preventer body.
