Product Description

ASTM D7400 Downhole Seismometers with 3D Borehole Geophones Downhole seismograph Downhole Testing Equipment


Introducing the premium ASTM D7400 Downhole Seismometers, equipped with state-of-the-art 3D Borehole Geophones, providing unparalleled precision in downhole seismic observation. This advanced Downhole Seismograph, an essential tool in our Downhole Testing Equipment lineup, ensures accurate and reliable data collection for your subsurface exploration needs.

Downhole seismometers can be further broken down into two different instrument types, namely, borehole seismometers and posthole seismometers. Borehole seismometers are downhole seismometers that are designed for deployment in steelcased deep boreholes. These seismometers typically include a holelock assembly as part of the instrument. A holelock is used to mechanically support and connect the seismometer to the borehole casing. It includes an actuator or a passive spring that pushes the entire seismometer against the side of the borehole with a substantial force. This force holds the seismometer rigidly in place and prevents the seismometer sliding down the hole.
