T
he New Schramm T500XD drill rig is designed
to accommodate torque management technology for enhanced horizontal drilling.
Over the last decade the horizontal drilling process has become much more efficient in part due
to better understanding of how to control and
manage torque and drag. The T500XD’s control system is designed to incorporate 3rd party
automated control technology such as the Slider
System® into the drilling process. The T500XD
top drive also incorporates a counter-rotation
hydraulic circuit that controls the release of drill
string torque energy at the surface, eliminating
damage to top drive and drill string components.
Some important advantages include:
• Increased Rate of Penetration and reach
capability
• Smoother weight transfer to the
bit, which increases bit life
• On-bottom toolface correction
while drilling
• Improved well trajectory
• Increased motor life, as stalling is
significantly decreased
• The ability to increase the length
of the horizontal section with
reduced twist, resulting in increased
production
• No lost-in-hole exposure
• Use of less mud additives for
lubricity enhancement since
surface rocking torque is used to
overcome friction
• Opportunity for directional drillers
to focus on data trends and other
critical issues instead of trying to
control the rocking manually
Several SPE papers including, “SPE 92558 Field
Proof of New Sliding Technology for Directional
Drilling” have been written on torque management technology. Please contact Pete Christian,
V.P. Engineering at [email protected] for

T
he job readiness and advancement potential of Penn College graduates was impressively
in evidence at the Schneebeli
Earth Science Center on September 6th, as Schramm Inc. – which
employs a number of alumni and
provides scholarships, internships
and other ongoing educational
opportunities for students –
demonstrated a T130XD mobile drilling rig in the School of
Natural Resources Management
parking lot. The 97,000-pound
rig, manufactured in West Chester
and carrying a $1.2 million price
tag, drew attention from a variety
of majors, including diesel, heavy
equipment and welding. Accompanying the rig were technical
field representatives Phil Delazio,
a 2010 alumnus of the college’s
heavy construction equipment
technology: Caterpillar equipment emphasis major, and Jeff
Roten. Schramm officials have
noted the attractiveness of Penn
College graduates’ get-rightto-work qualifications, remarks
borne out by the day’s returnees.
“I graduated on a Friday and was
on a service call Monday morn-
ing,” said Delazio, who maintains
25 rigs in shale gas areas of
Pennsylvania, West Virginia and
Ohio – and whose truck odometer
reflects 57,000 travel miles in just
11 months. “Most of our new hires
are from Penn College; in welding, manufacturing, service … just
about every department has at
least one graduate from here.” The
T130XD rig has been exhibited
for students before, but it is also a
familiar presence on the international stage. It (and Roten) played
a major role in reaching and rescuing 33 trapped Chilean copper
miners in October 2010. Roten’s

The classroom training was well received
but it didn’t stop there. Actual hands-on
training was performed at a local contractor’s yard. Attendees took a written
test and were graded to maximize their
learning and retention. They were also
provided with the latest update of our
Spanish language T685WS Operation and

Chain Adjustment
Steve Hanley, The Schramm-Man
In our last issue we discussed the
design of both the roller and leaf
type chain that Schramm uses
in the feed circuits of many of
our drill rigs. We also reviewed
methods of determining the
chain wear to aid in the planning
of chain replacement. Like most
things that are man-made,
they do not last forever and
eventually your chain must be
replaced. In this issue we will
look at the replacement and
adjustment of the feed chains
and their mating components.
After all the chain has been
removed from the mast, you
will want to inspect all of your
roller chain sprockets or leaf
chain sheaves and their pins
(axles) for wear. In the case of
the sprockets there is typically
an elongation at the root of
the tooth that also leads to a
narrowing of the tooth itself. This
is the result of an extremely worn
chain and poor lubrication that
has created too much distance
between the individual rollers.
When this chain is in tension
from drill string weight, the
rollers will erode the sprocket
teeth. This type of wear warrants
replacement of the sprocket.
Attempting to use new chain
with worn sprockets will only
lead to premature chain failure.
4
If the sprockets or sheave appear to be in
usable condition, you still should remove
the pins and inspect both the pins and
bushings for wear. There are thrust washers
on either side of these components to
absorb the wear from any side loads. Many
lower sheaves or sprockets incorporate a
lip seal as a preventative measure to limit
intrusion of contaminants. All of these items
must be inspected and replaced as needed,
in order to maintain a proper operating
feed system.
So now you are ready to install your new
chain. The most critical dimension to
consider in the case of roller chain masts
with dual feed cylinders is the distance from
the timing tube on the crown of the mast to
the connection at the trunnion bar spacers
by the rotation gearbox. The tooth count
must be equal to insure that the rotation
gearbox will hang and travel straight
when feeding up and down the mast.
The timing tube design on these systems
changed in the early nineties from an inline
sprocket (Illustration 1) to a half pitch offset
(Illustration 2). With this design timing tube
you will have to have one side one half
pitch in advance of the second side when
doing you initial connection. You will also
want to leave the jam nut at the trunnion
spacer block backed off on one side until
chain tension is set.
Chain Adjustment (continued)
“
Illustration 2
Illustration 1
To set proper chain tension you must
bring the rotation gearbox to the table.
Place a steel plate on the table and use the
slow feed circuit with the down feed relief
A
ir-Control®, Schramm’s patented
compressor control system
started in 2005 as a subsystem of
i-Control® rig operator interface.
Since then it has evolved into the
industry performance standard for
drill rigs supplied with on board air
compressors.
If you provide proper
lubrication and adjustment,
you can double the life of
your feed chain.”
backed out to apply minimal pressure
of the gearbox shaft against the plate.
Slowly apply pressure using the down
feed relief valve; 200 to 300 psi (13.8
to 20.7 bar) for the leaf type chain and
500 to 600 psi (34.5 to 41.4 bar) for the
roller type chain. Lower the mast to the
transport position and leave the engine
running to maintain hydraulic pressure in
the feed circuit. Using the chain adjusters
you want to achieve three inches of sag
in leaf type chain and two and one half
inches of sag in the roller type chain. This
measurement is to be taken in middle
of the upper chain with the rotation
gearbox at the table.
Once chain tension is set on the dual feed
cylinder masts you must measure the
distance from the table to the bottom of
the trunnion plates on each side to insure
a proper alignment of the gearbox shaft
to the slipbox. This distance is adjusted
with the screws that pass through the
trunnion spacers. Once set you can lock
the jam nuts at all adjustments points
and make sure the mechanical locks for
all nuts are engaged. Lastly, install any
guards that were removed for easy access
to insure proper personal protection.

Service Tips with The Schramm-Man
Lower Chain Guard
NOTE: As the chain begins to wear
you will have to remove links in
order to maintain proper chain
adjustment. Make certain that you
alternate link removal from the
upper chains the first time, and
then the lower chains the next time,
etc. Removing from one set all of
the time will move the terminal
location of the rotation gearbox in
that direction. For example: If you
remove links from the top chain only,
the rotation gearbox will be closer
to the mast crown when the feed
cylinders are fully closed. When the
feed cylinder is fully extended the
rotation gearbox will not reach the
table.
In closing, a final reminder that if
you provide proper lubrication and
adjustment, you can double the
life of your feed chain and prevent
unwanted damage to the feed
cylinder rods.

Today over Schramm 100 rigs
operate with air-Control, including
rigs in the USA, Canada, Mexico,
Dominican Republic, Australia, Chile,
Peru, China, Mongolia, Saipan and
Russia. Africa in particular is very
well represented, with systems
operating in Tanzania, Mali, Burkina
Faso, Ghana, Senegal, South Africa,
Zambia and the Democratic Republic
of the Congo.
Fuel consumption reductions of up
to 12 percent drive the interest in this
system, along with the additional
benefits of reduced wear and tear
on the engine and compressor by
optimizing horsepower to rig air
demand.
Customers acknowledge that learning
about air-Control is one of the most
beneficial take-aways from Schramm
service schools. Geotec Boyles Bros in
Santiago, Chile has taken it a step further.
With multiple air-Control systems installed
across their Schramm drill rig fleet, Geotec
Boyles built an operating air-Control test
stand in their facilities. From this test stand,
