Smooth Ride to Success for APS Drilling Tool
Using Magnetorheological Fluid

Using magnetorheological fluid to dampen vibration, a dynamically adjustable drilling tool from APS Technology is helping oil
and gas companies achieve impressive results in their expensive
drilling operations. APS has rebranded and relaunched its active
vibration damper device to reflect its multiple capabilities.

William Turner,
CEO of
APS Technology

" We are excited to relaunch AVD as the
SureDrill-IPDT (Intelligent Performance
Drilling Tool), " said William Turner, CEO.
" The new name conveys the device's
proven ability to actively mitigate a myriad
of adverse drilling conditions, improve ROP
(rate of penetration) and enhance overall
drilling performance. " It has demonstrated
50% improvements in ROP and doubled
the life of pricey drill bits in the field due to
reduced vibration, he said.

Its damper chamber is filled with a magnetorheological fluid that has electronically controlled viscosity providing programmable stiffness. An integrated
motion sensor measures displacement several times per second
and changes the damping factor over a 7-to-1 range based on
observed drilling conditions.

By keeping tool string damping in the right range for current drilling conditions, the IPDT significantly reduces vibration, maintaining the bit in better contact with the formation and increasing
ROP.

Based on the design of magnetic ride suspension control in
automobiles, APS adapted the technology for oilfield drilling
by engineering a system comprised of three main sections:
the spring and torsional bearing section, which is similar to a
standard shock sub; the middle damper section with the MR
valve assembly, which includes a shaft position sensor, and the
compensation system; and the upper section which has a turbine
alternator to provide power, the control electronics, and a sensor
section, which measures high frequency shock and vibration, and
changes in rotational speed. A white paper available on the APS
website, " Making the Most of Magnetism, " explains the technology in detail.
Based in Wallingford, Connecticut, APS provides of an assortment of drilling optimization products used in the oil and gas
industry. It also provides product development services and
proprietary products to customers worldwide based on its engineering expertise in the design, development and manufacture
of oilfield electronic, mechanical, instrumentation, sensor and
software products; shock and vibration isolation designs; stress
analysis for static and rotating conditions; and mechanical and
electronics analysis for harsh environments. For more info, see

High-Temp Ferrite Key to Murata Chip Beads
for Noise Suppression

Selecting a ferrite material that retains its magnetic properties
at high temperatures, Murata has developed a series of chip
ferrite beads for noise suppression in automotive power lines at
temperatures up to 175°C .
As electrification advances, the company notes, demand for
compact, lightweight and robust electronic control substrates
continues to grow, particularly as more and more electronic control units (ECUs) are positioned closer to the engine. Previously,
automotive engineers have not been able to directly address
power line noise suppression, instead implementing them in
cooler areas which complicates the design.
The new BLM18KN_EH series of chip ferrite beads helps
engineers meet this design challenge. Target applications are
automotive equipment such as engine and transmission ECUs
and turbo motor controllers. Another key element in their design
is use of an electrode able to suppress temperature-related
deterioration.
