Until the advent of this technology, there was no removable packer available for Ultra High Pressure (HP)/High Temperature (HT) wells. Previously, the industry was required to rely on permanently installed production packers utilizing then-available technology, which was not always a solution that was the most efficient or cost effective for end-users. Specifically, in order to remove such permanently-installed packers, end-users would have to undertake what could be a costly and time-intensive process, including milling time, fishing time and non-productive time in order to retrieve the permanently-installed packer; the end result of which could cause damage to the casing. To respond directly to this challenge and clear industry need, the Ultra HP/HT Removable Production Packer described in this paper was developed: this is the first industry Packer that can be removed after having been exposed to pressures of up to 20,000 psi (1379 bar), 450°F (232°C) temperature and loads that can reach 900,000 lbf while maintaining a gas-tight seal. This removable production packer has successfully passed the API 11D1/ISO 14310 grade V0 test.
