All over the world, ServoCon ALPHA products are being used every day to
find and refine the oil and gas the world depends on, to generate the
power that industry needs, and to manufacture the chemicals and petrochemicals
that are essential components of a multitude of items we take for granted.
Established in 1979, ServoCon ALPHA designs and manufactures high quality,
reliable, state-of-the-art control systems for Gas and Steam Turbines,
as well as control systems for plant, station and process applications,
and Emergency Shutdown Systems.
Drilling applications using high-powered drilling motors for every formation
and bit type utilize an adaptation of the Moineau principle in their power
sections to convert hydraulic power from the drilling fluid into mechanical
power, which drives the bit. Motors are available in a wide variety of
sizes and power sections to provide the right combination of torque, speed
and flow capabilities for every formation and bit type.
Sub-assemblies of each motor include a dump valve which is a hydraulically
actuated valve assembly at the top of each tool allowing the drill string
to fill or drain when tools are tripping in or out of the hole. When pumps
are on, the valve automatically closes to direct all mud flow through
In 1930, the worlds very first Progressing Cavity Pump (PCP) was designed
by René Moineau, the founder and original inventor. A PCP consists
of a single helical rotor which rotates inside a double internal helical
stator. The rotor is precisely machined from high strength steel the stator
is molded of resilient elastomer. This makes the unit pump viscous fluids.
Completion for oil production, the stator is fixed to the tubing and the
rotor is attached to a sucker rod string. The pump is driven by rotation
of the sucker rod string. Large particle handling : The rotors are plated
with a hard material to resist abrasion. Abrasive particles which are
caught between the rotor and the stator are pressed into the elastic wall
of the stator and then expelled into the next cavity when the rotor has
passed. The flow rate is proportional to pump speed as the PCP is a volumetric
pump, the flow rate depends only on the rotor speed. Therefore the pump
can be exactly matched to the well inflow rate for optimum production.
The process utilizes Seismic reflection profiling, successfully used by
Cornell researchers elsewhere in the world. It is a technique to image
the Earth by sending energy waves into the ground and having them reflect
back to monitors on the surface. The energy can be from explosive charges
or large vibrating trucks, equipped with Vibrasize machines.
Vibrasize machines have servovalves and large hydraulic cylinders or
actuating rams that tamp the earth as the machine rides over a test site.
The result is an acoustic map that computers transform into a two-dimensional
image showing structures deep within the earth. Cornell scientists pioneered
the use of this technique to systematically explore the continents.
