Abstract

A tubing nipple impression device for use within downhole tubing includes a driver body, a stopping disk, first and second impression arms, and upper and lower radial springs. The driver body extends in an axial direction along a vertical axis of the downhole tubing. The driver body further includes a nose portion, and first and second driver arms that abut against the stopping disk. The shear pin attaches the driver body to the stopping disk. The first and second impression arms are fixed to the stopping disk, and are further connected to each other with upper and lower radial springs. The first and second impression arms are actuated by the nose portion to form first and second impressions complimentary to first and second portions of a tubing nipple, respectively, when the first and second impression arms abut against the tubing nipple.
