SpecialReport: Frac Tech
one works by using fluidic force to generate
pressure pulses that vibrate the coiled
tubing, " Schultz describes. " By conducting
research at our lab and analyzing past
jobs, we try to identify the vibration rate
and resonant frequencies that will be most
effective at moving a specific string of
coil in a given formation. "
Schultz calls this science vital to the
tool's effectiveness. " If a tool vibrates
the string too hard or at the wrong frequency, it will barely move the tubing
and will cause undue damage to the
motor, the tubing and even the surface
equipment, " he warns.
" Our new tool is able to move coil
faster and farther because it gives us
greater control over the type of vibration
it creates, " he says. " With it, we can turn
the component that generates the pressure
pulses on and off, which lets us adjust
the vibration's shape. "
Schultz adds that the tool imposes
less pressure drop on the fluid that passes
through it, which leaves more energy
available to clean plug fragments or other
debris from the well.

Plug-Free Completions
In many wells, Schultz says it is
possible to reduce or eliminate plugs
by temporarily blocking perforations
using diverter pods with tassels on both
sides that allow downhole currents to
carry the pods to perforations. Once
there, Schultz says the pods create a
reliable seal, even around unusually
shaped perforations.
" The pods are made from a degradable
material, so eventually, they will go away, "
he says. " This saves the operator the time
and cost associated with installing and
milling out plugs. "
During 2020, Schultz says Thru Tubing
accelerated efforts to expand the pods'
application window. " We have developed
new materials that degrade at more predicable rates and allow us to create smaller
pods that still have the strength to withstand the pressures they need to endure
during the frac, " he details.
Pod size is a Goldilocks challenge,
Schultz notes. " If the pod is too small, it
will not seal the perforation or will get
pushed through as pressures increase.

NRG Safe is dedicated to safety in the oil and gas
industry. Our solar powered LED safety markers
are the preferred option when electricity is not
available on your location. These markers also aid
in darkened roadway illumination, lane delineation
and as a wrong way driver deterrent to create a
safer environment on high-traf昀c roads.

But if it is too big, it will clog the well, "
he explains. " With smaller pods available,
we can get the optimal pod size in more
wells.
" In addition to developing new pod
materials, we are refining our surface
and downhole delivery systems, " he
adds. " These systems use computer-controlled equipment to release pods gradually so they find individual holes more
reliably and efficiently. For example,
we can tell them to release two pods
every five seconds, or one pod every 10
minutes. "
If too many pods are released at once,
most of them will flow toward the handful
of perforations that break down first,
which could leave perforations at the top
of the well unsealed. Schultz says spacing
the pods' deployment addresses this problem by ensuring there are pods above
each perforation as it breaks down and
begins taking fluid.
" These delivery systems will make a
huge difference in the pods' reliability,
so they will help us reduce clients' completion costs, " he says.
