New sensor supports oil exploration
Sensor Systems claim to have made a the first advancement in almost 50 years in seismic sensors.
The new device, an all-optical, fiber-optic omnidirectional geophone, requires no in-situ electronics, copper conductors, or electrical power. It incorporates a self-contained optical interrogation unit (using an optical time division multiplexing methodology) with integrated laser sources; all of the system [...]
Vibroseis versus Dynamite
I’m currently on a 2D job which is mainly flat but it does have one portion in the middle which has some hills requiring bulldozer cutting. The client emailed me the other day asking about using vibes in the hills as somebody at the office had asked if it wouldn’t be better to use dynamite. [...]
Passive Seismic Mapping PSTT
I recently came across an interesting article about a 3D seismic technology which does not use traditional type sources making it possible to use the technique in places otherwise locked out due to environmental concerns.
Passive seismic mapping using passive seismic transmission tomography (PSTT) is a seismic technique which uses a sparse array of 3C [...]
