THE REVABULL WIPER The Ultimate Drill Pipe Wiper.

The All New RevaBull Wiper is a revolutionary tool on the drill
floor. This handheld drill pipe wiper wipes mud clean
from the drill pipes and drill collars as they are being pulled
out of the hole. Unlike the traditional method of using a
rubber hose or a nylon rope with rubber grip, the RevaBull
Wiperperforms a very clean and efficient job while
ensuring safety of the operator. The device increases safety for
workers on the rig and allows companies to collectmore valuable
oil- based mud. Companies that manage onshore and offshore oil rigs
will benefit from the RevaBull
Wiperto make the entire operation safer and more profitable.
The RevaBull Wiper
The wiper is made from 2 symmetrical halves which both have a
flexible wiper insert that can accommodate different
size drill pipes and drill collars. The operator simply wraps
the tool around the drill pipe or drill collar and locks it
into
place using the magnetic locks at the opening. Should the stress
on the tool exceed the calibrated safe operating
stress, the magnetic lock will open up to ensure safety of the
operator and those nearby. A locking lever model is also
available for operators who prefer a mechanical lock against a
magnetic lock.
The resistance of the tool on the drill pipe as it comes up out
of the hole has almost zero weight to it. The weight of the
operators is all that is required to keep the tool down. Special
wiper blades are available for specific applications such
as wiping mud from drill collars or heavy spirals. These special
wiper blades allow almost 80% mud recovery by
wiping mud from the hard to reach places that are left out by
conventional wipers.

Safety & Efficiency Impact
1> MAXIMIZES PRECIOUS MUD RECOVERY:
Thanks to its unique design and various wiper blades, the
Reva-Bull Wiperensures almost 95% mudrecovery. The special wiper
blades designed for drill collars ensure that maximum mud is
recovered from the
drill collars, especially the spiral grooves of the drill collar
from where traditional drill pipers fail to wipe mud.
2> EXTREMELY SAFE WHEN COMPARED TO THE TRADITIONAL RUBBER
HOSE:
Most of the rigs use a rubber hose or a nylon rope for wiping
the drill pipe as it comes out of the drill hole. This
rubber hose is an unsafe tool as it lacks proper grip in the oil
filled mud. When the hose comes in contact with
the drill pipe tool joint, the operator has to use his hands or
fore fingers to keep the hose tight against the face
of the tool joint. Often, metal shavings generated from the
roughneck jaws might pierce through the gloves
and injure the operators hands as he tries to use the hose and
his fore fingers to wipe the pipe. The RevaBull
Wipereliminates all these completely.
3> MINIMIZES CHANCES OF CAVE-IN:
Drilling and tripping in the unsafe zone is very critical and
time is a serious factor as there is a very high
chance of well cave in. This is because the drill bit is
drilling in a new zone that is unprotected by the casing.
Should a cave in occur, it will result in many hours of down
time and losses to the drilling company. Installing
conventional wipers can be time consuming and thus increasing
the chances of cave in as the time involved
to pull the drill pipe out from the well is increased. The
Reva-Bull Wiperprovides a new innovative approach
that minimizes this potential cave-in time.
4> PHYSICAL INJURY DUE TO IMPROPER HANDLING IS AVOIDED:
The rubber hose often gets entrapped around the tool joint which
has a larger diameter than the drill pipe.
This can lead to a sudden upward jerk which can cause injury to
the arms of the operator. The RevaBull
Wipereliminates this problem completely as its innovative
magnetic lock design will automatically open up on
sudden excessive impact releasing the tool from the drill
pipe.
5> PROPER GRIPPING OF THE WIPER TOOL ENSURES NO SLIPAGE:
Every time the operator uses the rubber hose he has to wear
rubber gloves. An oil film generated from the
drilling mud disallows proper gripping of the hose with the
gloves. TheRevaBull Wiperensures that the
operator has sufficient grip to wipe the mud effectively and
thus is in control of the operation at all times.
6> MINIMIZES OPERATOR CONTACT WITH REACTIVE OIL BASED MUD
Synthetic / Oil Base Mud contain chemicals that are hazardous to
the human skin. Using rubber gloves and
loose ends of rubber hoses with no control of mud deflection or
direction usually leads to the OBM (Oil Based
Mud) to come in contact with the operators skin around the wrist
and forearm areas. This mud causes severeallergic reactions to many
people and could result in employee dismissal. The RevaBull
Wiperdiscourages
contact of the OBM with the operator by allowing the operator to
deflect mud away from his body. The grips of
the tool will provide a much safe operation and more control for
the operator while wiping down the pipe.
