DMC Global Inc. operates a diversified family of technical product and process
businesses serving the energy, industrial and infrastructure markets. Our businesses
operate globally through an international network of manufacturing, distribution
and sales facilities.
Our business is organized into two segments: NobelClad and DynaEnergetics.
NobelClad is a global leader in the production of explosion-welded clad metal
plates for use in the construction of corrosion resistant industrial processing
equipment and specialized transition joints. DynaEnergetics designs, manufactures
and distributes products utilized by the global oil and gas industry principally
for the perforation of oil and gas wells.
DynaEnergetics has been producing detonating cord and detonators and selling
these along with seismic explosives systems for decades. Since 1994, the business
has placed significant emphasis on enhancing its offering by improving existing
products and adding new products through research and development, as well as
acquisitions. Today, DynaEnergetics offers a comprehensive portfolio of detonating
cord, detonators, bi-directional boosters, shaped charges, and corresponding
gun systems.
In recent years, DynaEnergetics has increased its development efforts and introduced
several new products specifically designed for safe and selective perforating.
Included among these products is the DynaSelectTM family of intrinsically safe
integrated switch-detonators. DynaSelect detonators require a specific electronic
code for firing and are immune to induced currents and voltages, static electricity
and high-frequency irradiation. These safety features substantially reduce the
risk of unintentional detonation and enable concurrent perforating and hydraulic
fracturing operations at drilling sites with multiple wellbores, improving operating
efficiencies for customers.
Our DynaSelect products integrate our earlier Selectronic Switches with our
Intrinsically Safe Detonator technologies in a unique one-piece system for improved
well site efficiency, reliability, simplicity and service quality. The fully
integrated design incorporates advanced software controls and reduces the size
of the detonator and switch assembly. DynaSelect reduces by 40% the number of
electrical connections required within each perforating gun versus prior detonator
models. This improves set-up times and significantly increases reliability.
The DynaSelect detonator is controlled by our Mulitronic IV Firing Panel. This
system enables safe and reliable firing of up to 20 guns in a single run and
incorporates a signal output function to monitor the movement and position of
the tool string, resulting in significant time and cost savings.
Our DynaStageTM factory-assembled, quality assured, perforating system combines
all our advanced technologies into a preassembled perforating gun that can be
armed at the well site with the wireless DynaStage detonator, which incorporates
all of the features of the intrinsically safe DynaSelect detonator. The DynaStage
system is operated using our latest Multitronic V Firing Panel, and can be tested
before going down hole using our Surface Tester. The Multitronic V Firing Panel
is highly intuitive and allows the gun string to be safely tested and monitored
throughout the pump-down operation. The Multitronic V panel introduces several
new features designed to ease the use and the reliability of the system, including
“shoot-on-the-fly” operation through an instant-fire capability.
By safely checking perforating guns on the surface, the DynaStage Surface Tester
greatly reduces the risk of lost time, mishaps, misruns and misfires due to
a system fault. The Surface Tester is fully RP67 compliant and cannot initiate
any type of detonator or explosive device. The patent-pending plug-n-go design
of the DynaStage wireless detonator reduces the potential for errors by eliminating
the need for wiring and crimping. The fully integrated design of DynaStage minimizes
uncertainty and operational risks, achieving industry-leading perforating performance.
Our DynaSlotTM perforating system is designed for well abandonment operations.
During abandonment the wellbore is encased and permanently sealed so that layers
of sedimentary rock, and in particular freshwater aquifers, are pressure isolated
from the wellbore. The DynaSlot perforating system facilitates this process
by creating access to a full 360-degree area between the rock formations and
the tubing and casing. Customers use the unique, helical perforation pattern
created by DynaSlot to perform cement squeeze operations that seal off the wellbore.
DynaEnergetics develops and sells a wide range of shaped charges for use in
its perforating systems. These include the family of HaloFrac™ charges,
which incorporate advancements in liner materials and shaped charge geometry
designed to improve hydraulic fracturing performance through lower and more
consistent breakdown pressures, uniform proppant placement, uniform frac clusters
and higher well productivity ratios. Another line, FracTune™, delivers
uniform hole diameter in the well casing independent of shot phasing and gun
positioning within the well bore. DynaEnergetics also sells the DPEX™
family of charges, which feature energetic liners. All three lines can be used
with the DynaStage perforating system, as well as conventional perforating gun
systems across a range of gun diameters.
DynaEnergetics Tubing Conveyed Perforating, (TCP) systems are customized for
individual customer needs and well applications. TCP enables perforating of
more complex highly deviated and horizontal wells. These types of wells are
increasingly being drilled by the industry. TCP tools also perforate long intervals
in a single trip, which significantly improves rig efficiency. Our TCP tool
range includes mechanical and hydraulic firing systems, gun releases, under-balancing
devices and auxiliary components. Our tools are designed to withstand downhole
temperatures of up to 260 degrees Celsius (500 degrees Fahrenheit), for safe
and quick assembly at the well site, and to allow unrestricted total system
length.
The principal product of metal cladding, regardless of the process used, is
a metal plate composed of two or more dissimilar metals, usually a corrosion
resistant metal (the "cladder") bonded to a steel backing plate. Prior
to the explosion-welding process, the materials are inspected, the mating surfaces
are ground, and the metal plates are assembled for cladding. The process involves
placing a sheet of the cladder over a parallel plate of backer material and
then covering the cladder with a layer of specifically formulated explosive
powder. A small gap or “standoff space” is maintained between the
cladder and backer using small spacers. The explosion is then initiated on one
side of the cladder and travels across the surface of the cladder forcing it
onto the backer. The explosion happens in approximately one-thousandth of a
second. The collision conditions cause a thin layer of the mating surfaces,
as well as the spacers, to be spalled away in a jet. This action removes oxides
and surface contaminants immediately ahead of the collision point. The extreme
pressures force the two metal components together, creating a metallurgical
bond between them. The explosion welding process produces a strong, ductile,
continuous metallurgical weld over the clad surface. After the explosion is
completed, the resulting clad plates are flattened and cut, and then undergo
testing and inspection to assure conformance with internationally accepted product
specifications.
