Abstract: A snubbing jack includes a first telescopic member and a second telescopic member. A stationary plate and a movable plate are affixed to the telescopic members. The movable plate moves away from the stationary plate upon expansion of the telescopic member and moves toward the stationary plate upon contraction of the telescopic members. An intermediate plate is removably secured between the stationary plate and the movable plate.

Abstract: A method for restraining tubular members during well servicing. A first step involves monitoring a velocity of tubular members as they are withdrawn from a well. A second step involves activating a tubing restrainer when the velocity of the tubular members exceeds a predetermined threshold.

Abstract: A hanger flange includes an annular body having a circumferential inner surface defining a central passage and a circumferential outer surface. Ram alignment apertures are provided within the body spaced radially about the passage. Each of the apertures has a first portion with a non-circular first cross-sectional dimension extending radially outwardly from the inner surface and a second portion with a second cross-sectional dimension extending radially inwardly from the outer surface. A ram is positioned in each of the apertures. Each ram has a first portion having a first cross-sectional dimension corresponding with the first cross-sectional dimension of the apertures, and a second portion having a second cross-section dimension corresponding with the second cross-sectional dimension of the apertures.
