| titleOfInvention | Rotation release two-way well casing hanger |
| abstract | ROTATION RELEASE TWO-WAY WELL CASING HANGER BY AMARESWAR (NMI) AMANCHARLA, and CARTER R. YOUNG "Abstract of the Disclosure" A well casing hanger for suspending a string of tubing from an outer casing landing nipple, with the hanger structure automatically engaging the nipple structure and latched to a locked state withstanding either suspended weight or upward pull in tension. Hanger structure release is provided by rotation of a member operating a threaded coupling on the upper end of the hanger-operating mandrel through providing a recess to accommodate internal lugs of locking keys so they can be cammed inwardly and unlocked with lifting upward movement of the hanger structure from the land-ing nipple. |
