Applied Physics Systems is a leading manufacturer of sensors and systems used in oil field,
industrial and scientific applications.  We design and engineer all of the products we supply.
Our primary products are directional sensors, magnetometers and downhole drilling sensors
and electronics.

History: Applied Physics Systems was founded in 1976 by Bill Goodman and for over
thirty years has developed expertise in the design and manufacture of magnetometer
sensors.  In the last fifteen years, Applied Physics has developed and expanded its
products for drilling systems, electrical, mechanical, and computer software systems.

Applied Physics Systems is a leader in the manufacture of magnetic field measuring
equipment, including fluxgate magnetometers and clip-on milliammeters. We also
manufacture a broad line of angular orientation measuring sensors, including steering
sensors for directional drilling applications and miniaturized sensors for general purpose use.

In addition to our standard products, APS conducts contract research for other organizations
in the fields of its expertise. APS can design and build modified versions of our instruments
as well as completely new instruments to solve your needs for magnetic field measurement,
orientation sensors, steering tools and clip-on milliammeters.

APS is also a world leader in the design and production of Rock Magnetometer systems
and accessories. These systems are produced in partnership with William S. Goree, Inc.
and are sold under the 2G Enterprises name. 2G has its own web site with complete
information on the instruments offered: http://www.2GEnterprises.com




APS has expanded into its new, state-of-the-art production facilities in Sunnyvale, California.
Our new address is 281 East Java Drive, Sunnyvale, CA 94089 USA



Applied Physics Systems has begun field tests in North America of our new Model 600
Near Bit Sub. Designed to be run with the AP-250 EM MWD System, the Model 600
comes in 5” and 6.5” sizes, both with a length of 36”. On-board sensor and electronics
packages provide inclination, azimuthal gamma, vibration, and rotation data, all transmitted
wirelessly to the AP-250 EM MWD System located above the power section of the BHA
where it is then transmitted to the operator on the surface via EM telemetry.  

Field testing is expected to last 30-60 days with a commercial product release to follow
upon successful completion.
