Fin bottom to aid in preventing "Spinning" during drillout
Set with Model MSB Mechanical Setting Tool

Many of the outstanding features of our wireline plugs and packers have been incorporated into the Models 'STMB' or 'STWB' Bridge Plugs. Both are rugged, compact units engineered for fast running downhole on mechanical setting tool. Positively-secured packing element and one piece slips combine to resist premature setting due to well debris or rough handling and assures protection from the hazards of high-speed running in the well. The metal backup rings prevent extrusion of the rubber at high pressure and temperature. Because of their design, the metal-to-metal contact developed by these backup rings is made more secure by pressure increases. An internal ratchet lock ring retains the dynamic force induced in the retainers during the setting operation. This simple mechanism assures continued compression of the packing elements regardless of pressure differentials. Case-hardened, one piece slips, designed to bite into the hardest casing, are located at each end of retainer - final assurance of retainer pack-off security. When the need arises, these slips are easily drilled out.

Operating Instructions
RUNNING-IN AND MECHANICAL SETTING INSTRUCTIONS
The setting tool is designed for use in varied hole conditions and employs several features to prevent premature setting of the retainer or bridge plug or damage to the tool. It is suggested that the tool be run at a moderate speed while avoiding sudden stops. Note: While running in, care must be taken to prevent right-hand rotation from being transmitted to the setting tool. Under no circumstance must there be allowed more than four turns of the tubing to the right while running in. As a precaution, after every 10 to 15 stands, one left hand turn should be placed in the work string. When the desired setting depth has been reached, the tools should be picked up two (2) feet above the desired setting point. This movement is necessary to provide the required tool stroke to release the upper slips and allow the Control Nut to move freely. Rotate the work string to the right sufficiently to transmit 10 turns to the tool. This right-hand rotation will thread the Control Nut off its matching thread on the Mechanical Setting Tool mandrel and release the Control Sleeve from the running in position. Lower the tools back down to the desired setting depth. The Drag Springs will support the Control Sleeve and Setting Sleeve. The downward motion will push the upper slips from under the Setting Sleeve. The upper slip segments are then forced out against the casing by the leaf springs attached to the inside of each slip segment. When the upper slips are released, the Retaining Sleeve is pulled from over the Dog allowing it to move out and release the Control Latch from the Stinger Sub Body. Refer to the following chart and pull tension over pipe weight at the tool to set the slips and affect packoff.

TENSION REQUIREMENTS
Size tool	Min. Tension	Max. Tension
4 1/2-5 3/4"	33,000 lb.	36,000 lb.
6 5/8" & Larger	50,000 lb.	55,000 lb.

It is recommended that the maximum tension shown above be pulled when possible. However, to assure sufficient packoff and slip breakage, the minimum tension shown must be pulled.
The Mechanical Setting tool is released from the Cement Retainer of Bridge Plug by pulling 500-1000 lbs. tension at the tool and then rotating the work string 10 turns to the right at the tool. This will shear the rotational lock screw and unscrew the Control Latch from the Cement Retainer or Bridge Plug.
