n: The total outer surface of unit weight or unit volume .

n: density times the attraction of gravity.

the weight of a volume per unit of volume.

n: A facility that can adjust valve automatically according to the density of drilling fluid.

n: a rod positioned between two lifting lines so that the weight of a joint being lifted off the trailer is evenly distributed and the pipe does not buckle in the center.

n: a downhole permanent, or drillable, packer that is set by lowering some of the weight of the tubing string onto the packer. The weight expands the packers sealing element to prevent flow between the tubing string and the casing below the packer. squeeze point n: the depth in a wellbore at which cement is to be squeezed.

a millable retainer for squeeze cementing.

n: a special threadless tool joint for large-diameter pipe, especially conductor pipe, sometimes used on offshore drilling rigs. When the box is brought down over the pin and weight is applied, a locking device is actuated to seat the joints. Because no rotation is required to make up these joints, their use can save time when the conductor pipe is being run. Squnch Joint is a registered trademark of the manufacturer.

n: brass of a specified density used in fabricating precision balance weights.

n: the root mean Square (rms) deviation of the observed values from the average. standard dress n: diving equipment consisting of brass diving helmet, breastplate, heavy dry suit, weighted boots, weighted belt, hose, compressor, and communications.

a weight bar.

v: 1. to pull rods and tubing from a well at the same time-for example, when the pump is stuck. Tubing must be shipped over the rods a joint at a time, and the exposed sucker rod is then backed off and removed. 2. to move the drill stem, tubing, and other tools into or out of the hole with the well closed in. If the weight of the pipe is sufficient to overcome the upward force of well pressure, then the pipe can be shipped in. Compare snub.
