Applications are not limited to only surface seismic surveys, but also include borehole seismic methods such as VSP and crosshole imaging. To date, tens of 2D and 3D …
Seismic & Sonar Testing
Seismic Testing According to government estimates, 138,500 whales and dolphins will soon be injured and possibly killed along the east coast of the U.S. if exploration companies are allowed to use dangerous blasts of noise to search for offshore oil and gas. And geophysical companies — working on behalf of oil and gas corporations — are ...
Seismic Velocity (P-S) Suspension Logging in Philippines
How the PS Logger Works. The PS Logger is a full waveform acoustic probe, designed to measure compressional and shear wave velocities in soils and rock formations. It operates using indirect excitation rather than mode conversion as in a conventional sonic. It can acquire high-resolution P and S wave data in borehole depths of up to 600m.
PADCOM to build Manitoba's first potash mine near Russell
Daymon Guillas, president of PADCOM, said the potash mine is expected to create 17 to 25 new jobs in the region as early as October, when the operation is anticipated to start. According to the Canadian government website, the project would include a potash processing facility with centrifuge and dryer. Potash would be mined using hot brine ...

Super quick Mining Question. DO I want Fixed Abrasion Blasters? etc?
Garrus. Dec 23, 2018. #2. Short answer - if you want to take advantage of the new mining techniques present in the 3.3 update - yes, you'll want an abrasion blaster, a seismic charge launcher and the pulse wave analyser. You'll also probably want a detailed surface scanner (which is an optional internal for your ship, not a utility module).
Progress and development directions of stimulation
It is difficult to identify micro- seismic signals in wells more than 6000 m deep. Various kinds of direct physical detection equipment can’t work at temperatures above 180 C and pressures over 120 MPa. As exploration goes to deeper reservoirs, limitations of direct monitoring technologies will further stand out. 2.2.
Borehole Seismic
Find clarity in the borehole. Through seismic profiling, Halliburton borehole seismic services give operators a clearer view of their reservoir. Using geophones or distributed acoustic sensing (DAS) for vertical seismic profile (VSP) data acquisition, operators gain more data than ever to validate or improve decision making.

Seismic Survey
Seismic surveys are conducted by deploying an array of energy sources and an array of sensors or receivers in an area of interest. Figure 3.9 shows a seismic survey on land. The source of seismic waves is either an explosive which directly generates the seismic wavelet or a mechanical source which is commonly a vibrator, which uses a steel base plate in …
Seismic | Geoscience Australia
Seismic. Seismic data is the principal geophysical method used to image the subsurface in both land and marine environments. Geoscience Australia has recognised the importance of the seismic technique since the late 1940s and is a world leader in integrating seismic data with other Earth imaging and surface geology datasets to understand ...
Coal mining
Coal mining - Prospecting, Exploration, Mining: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been …
What is seismic blasting?
Seismic testing is the first step in oil and gas exploration in our oceans. Seismic vessels tow an array of airguns and audio receivers (hydrophones) behind them. These powerful airguns fire loud blasts of compressed air every 10 to 15 seconds. The sound waves produced penetrate deep into the seabed, and those that bounce back to …
