What is Seismic Land Streamer

A seismic land streamer is an array of geophones designed to be towed along with ground. It is a receiver array which specially designed for land seismic surveys. A land streamer is suitable for MASW, refraction, reflection and surface-wave surveys which make the field survey more easier and higher productivity without compromising data quality.

The concept of land streamer originally from marine streamers, as an array of hydrophones towed behind ships. Land geophysicists learned the concept of “ streamer” and applied it in land seismic survey and developed seismic land streamer. Land streamer surveys are excellent in many applications, while making the survey economically feasible, low cost, easy to move, deploy and collect. Any type of land cased geophone can be worked with Land Streamers – vertical, horizontal or three-component but most widely used geophone type will be 4.5Hz vertical geophones or 14Hz vertical geophones. High frequency geophones such as 40Hz, 60Hz or 100Hz geophone could also be supplied as per client’s applying requests. Three component geophones and shear wave geophones can also be worked with land streamers.

Usually a land streamer is a empty instrument equipped with base plates, tow webbing, loops, base plates and anti-rotation wings. Geophone spread cable and geophones may be supplied with selected configurations to meet client’s requests.

There are several companies who supply excellent land streamer, such as Geodevice, Geomatrix and Geostuff. Anyway Seis Tech is specialized to supply geophones and geophone spread cables which will be work partnering with land streamers. Geophone intervals can be varied from 1m to 10m and number of channels may be varied from 12 channels to 96 channels. To suit with land streamer, a Kooter cable take-out or KCK cable take-out will be the most preferred due to it’s excellent moistureproof ability but wire wrapped Mueller clip cable take-out or split spring take-out is also acceptable.
