SHADOW Frac PlugsEliminate post-frac intervention and accelerate return on investment
Plug-and-perf is used in an estimated 70-80% of new well completions…
Composite plug drillout delays the startup of production by three or more days, and exposes operators to the costs and risks associated with CT intervention.
but traditional composite plugs are standing between you and your investment.

A costly trade-offWhen it comes to unconventional wells,
plug-and-perf is a popular completion
option because of the extended stage
potential and larger inside diameter (ID)
production flow area versus ball and
sleeve systems. But, when composite plugs
are used to isolate zones the startup of
production can be delayed as long as three
or more days while the plugs and drop
balls are drilled out using coiled-tubing
(CT)-conveyed milling tools and debris
is circulated to the surface. This not only
prolongs completion times, it results in nn Additional planningnn More days on locationnn Increased HSE risknn Potential stuck incidentsnn Limited plug setting depthsnn Location restrictions

Cut completion costs. Accelerate ROI. Maximize production.SHADOW frac plugs are run in
hole on wireline and are set in
sequence along the lateral section
of the wellbore to isolate zones for
treatment, just like composite plugs.
The initial reservoir entry point is
created using our Alpha™ sleeve
pressure-actuated valve, rather than
a perforating gun run in on coiled
tubing. And after all zones have been
perforated and fractured, the plugs
stay in the well and production can
be turned on—without intervention
and with no reduction in
production volume.
SHADOW plugs feature a large flow-
through ID and use Baker Hughes
IN-Tallic™ disintegrating frac balls so
production can flow with the plugs in
place. IN-Tallic disintegrating frac balls
are made of controlled electrolytic
metallic (CEM) nanoconstructed
material—a technology pioneered
by Baker Hughes. IN-Tallic balls hold
pressure during fracturing operations,
then completely disintegrate in the
well when exposed to produced fluids
to prevent production blockages and
eliminate debris. IN-Tallic balls are
stronger than composite frac balls
and can withstand higher pressures
without deformation, enabling a larger
ID through the plug.
IN-Tallic frac balls disintegrate in the well and leave an unobstructed ID for maximum production.
SHADOW plugs let you flow back directly through an enlarged ID, saving you three or more days of milling time on each well.
Historically, intervention has been unavoidable in plug-and-perf
completions. Last year alone, operators set over 250,000 frac plugs in
North American wells and spent more than 30,000 days milling them
out before production could begin. But it doesn’t have to be that way.
The Baker Hughes SHADOW™ series frac plug allows you to bypass
CT intervention and start producing as soon as fracturing operations
are complete. The plug is designed to stay downhole and completely
eliminates the millout phase of plug-and-perf operations, increasing
operational efficiency and maximizing pay zone access.

SHADOW plugs can be set beyond the reach of CT milling tools so you can access more of your reservoir.
Go where you’ve never gone beforeWhen traditional composite plugs are run in
the well, they can only be set as far as the
reach of the CT-conveyed milling tools, which
is typically only 6,000 ft (1829 m). Because
SHADOW plugs stay in the well, they can be
set in horizontal sections beyond the reach
of CT, allowing you to expose more of your
reservoir to the wellbore. And, you can extend
your plug-and-perf operations to more remote
developments that previously would have
been limited by the accessibility of
intervention equipment.

SHADOW frac plugs saved USD 300,000 on two wellsAn operator in the Horn River Basin ran a total of 52 SHADOW frac
plugs in two wells on a seven-well pad. The other five wells were
completed with traditional composite plugs. During fracturing,
the SHADOW plugs provided reliable zonal isolation and ball seat
signatures were clearly visible on the pump charts.
After fracturing, the SHADOW wells were brought on production
immediately. Production from the other five wells was delayed for
three days while the operator milled out the composite plugs. Once
the wells completed with composite plugs were brought on line,
production charts confirmed that the wells with SHADOW plugs
produced at the same rate as the wells completed with
composite plugs.
SHADOW plugs saved the operator USD 150,000 in intervention
costs on each well. Based on the results of this field test, the
operator is adapting its entire operational structure around
SHADOW plugs and plans to use them in all future wells.
