Many of the outstanding features of our wireline plugs and packers have been incorporated into the Models 'MMB' and 'MWB' Bridge Plugs. Both are rugged, compact units engineered for fast running downhole on either tubing or electric wireline. 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 flat 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-hard ened, one piece slips, designed to bite into the hardest casing, are located at each end of plug - final assurance of plug pack-off security. When the need arises, these slips are easily drilled out.

Operating Instructions WIRELINE SETTING INSTRUCTIONS The Brdige Plugs can be set with Baker wireline pressure setting tools. The setting adapters-contain Baker adapter kits. Kit part numbers are listed in the retainer specification outline.

An adapter rod attached to the setting tool and attached to a mild steel release stud located in the body at the upper end of the bridge plug. A setting sleeve attached to the setting tool pushes against the lock ring backup of the bridge plugs. During setting, the sleeve holds the bridge plugs outside components and the rod pulls the bridge plugs body up; this action sets the slips and packs off the sealing element. The bridge plug, thus, is set by compression (instead of tension on vital components). At a predetermined tension it releases stud parts and allows the setting tool and adapters to be removed from the well. To rig the retainer for running, first screw the adjuster sub to the setting tool and make wrench tight. Then, tighten tension mandrel on the adjuster sub. Next,attach the setting sleeve to the setting tool and screw it completely back.

Suggested Drilling Technique for Bridge Plug The following is a general guide for the most successful drill out technique Bit Rotary Speed

New, short tooth, medium hard formation 75-125 RPM is recommended. Apply 5,000 - 7,000# until the top end of the center body of retainer is drilled away (3

Weight

- 5 in for 4-1/2" - 7" tools and 5 - 9 in for 7-5/8" and larger tools). Additional weight

on Bit

can now be applied across the full bit diameter. The weight increase is 2,000 3,000# per inch of bit diameter (i.e. 4-3/4" bit use 12,000 - 14,500# weight).

Drill Collars

8 minimum for 4-1/2" and 5-1/2" tools 12 or more for 7" and larger tools for weight.

Spudding the work string and variations in bit speed and bit weight should be made to help break up debris to re-establish penetration should it cease while drilling. One or more junk baskets should be used above the bit when normal circulation is to be used. If reverse circulation is planned,the casing scraper or other equipment in the tubing string

should have an inside fluid passage as large as the passage through the bit so cuttings will not bridge.

NOTE: Drilling times are directly related to tool size, bit stability, drilling weight, pump rate, bit RPM, type of bit, drillong fluid, etc. The same considerations should be used when drilling Bridge Plugs as would be used when drilling medium hard formations. The bridge plug is run to setting depth in the same manner as a conventional drillable packer or bridge plug. The packer components are shear pinned as a safety measure against premature setting caused by well conditions. Line speed should not exceed 200 feet per minute while running. During setting there may be one "kick" shown on the weight indicator. The kick will indicate the shear stud parting. After setting the bridge plug, pick up the setting tool a few feet then set back down and tag the retainer to assure the bridge plug is in place.
