sensors for directional drilling applications and miniaturized sensors for general purpose use.

In addition to our standard products, Applied Physics Systems conducts contract research for other organizations
in the fields of its expertise. Applied Physics Systems 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.

Applied Physics Systems 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

Applied Physics Systems 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 AP250 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.
