Hydraulic work over (Snubbing) services are increasingly

favored, having the advantage of eliminating the need to kill

the well. It lowers the cost as well as the time and problems

associated with circulating salt water, mud and other fluids.

The Cavins “Advance” Model “C,” “C-HD,” and “F” Spiders

have specifically been designed for snubbing operations. It

can work in its right side up position (Fig. 2) or in the inverted

upside down position (Fig. 1). The Spider Body and Slips are

specially designed for this service. The gripping Inserts how-

ever, are of standard design and are interchangeable with the

regular Cavins Spiders. Tubular Goods from 1.315" (1" O.D. to

5-1/2" O.D. can be handled with a clear opening for 6.050"

O.D. casing coupling with the Model “C” and “C-HD” Spiders.

Tubular goods 2-3/8" O.D. to 8-5/8" O.D. can be run with the

Model “F” Spider. All Spider models can be either hydraulic or

compressed air operated. A minimum of moving parts

assures a trouble-free operation.

A typical set of spiders on a snubbing rig is illustrated in

Fig. 3. Four spiders may be used: two (2) in the regular

(upright) position and two (2) in the inverted (snubbing) posi-

tion. One regular and one inverted spider are stationary and

the other regular and inverted spiders are mounted on the

traveling piston. The traveling spiders are used to either push

the pipe into the well or pull it from the well while the station-

ary spiders are used to hold the string of pipe when the trav-

eling spiders are not engaged.
