About Us 

Teledyne Geophysical Instruments has earned a strong reputation in the industry for delivering high-quality marine seismic exploration products. Our products are used aboard more than one-third of all commercial seismic research vessels.

The Teledyne name in the geophysical industry dates back to the 1960s, when some of our earliest designs for streamer cables, energy sources, and recording systems were put to use aboard seismic research vessels around the world. 

Geophysical Instruments carries on this tradition, and has earned a strong reputation in the industry for designing, building, and delivering high-quality, reliable, and durable marine seismic exploration products. Our products are used aboard more than one-third of all commercial seismic research vessels. 

We continue our focus on serving the needs of the geophysical industry, but we also eagerly assist non-geophysical organizations in finding solutions to their marine data acquisition needs. Our versatile designs for hydrophones and streamer cables can be easily adapted to a variety of unique applications. Additionally, we offer a variety of specialty products and services that are designed to meet specific needs of customers. 

Geophysical Instruments is strategically located to serve worldwide requirements with facilities in Houston, Texas  and Mitcheldean, England. 

In Mitcheldean, England, Teledyne Geophysical is accredited to Management System standards: ISO 9001:2015 / ISO 14001:2015 / OHSAS 18001:2007

What would it take to measure tiny pressure waves in an aquatic environment? Teledyne Geophysical Instruments. We design and manufacture sensor and sensor arrays for subsurface geological structure mapping to identify structures/features likely to contain hydrocarbon deposits; listeni​ng for the "signatures" associated with ships and submarines, engineering surveys below the ocean floor to facilitate pipe laying or structure placement and research associated with marine environment.

Exploration of the ocean bottoms for petroleum deposits is highly important in meeting the ever-increasing need for energy products. This exploration involves sophisticated research vessels towing arrays of long streamer cables with hundreds of hydrophones. An acoustic impulse generated at the vessel and reflected by the ocean bottom is received by the hydrophones. The collected signals are interpreted by highly complex data processors, with the results being predictions of petroleum deposits.

In addition to supplying hydrophones, array cables, and related hardware items, we provide repair services for our own equipment as well as that of other manufacturers. With facilities in both the Houston, Texas, and Mitcheldean, England, Geophysical Instruments is strategically located to serve worldwide requirements.​

To better serve the needs of the marine geophysical industry, Geophysical Instruments operates two cable repair facilities, one in Houston, Texas, and the other in Mitcheldean, England.

Both are capable of repairing streamer cables that we manufacture as well as cables manufactured by other major equipment suppliers. Our repair capabilities include analog, digital, fiber optic and solid cables. 

In addition to repairing streamer cables, we offer repair and termination services on towing leaders, vertical cables, and gun umbilicals. Further, we offer a wide range of customer specified testing, such as load testing of cables, durability testing, and ballast testing.
