Canadian geophysical services company GeoStrata Resources is expanding its capability to include downhole seismic. Historically a surface seismic data acquisition specialist, the company recently purchased a 20-level Sercel MaxiWave tool complete with the Wavelab acquisition and processing system. The digital downhole seismic array was selected to perform high-quality VSP and microseismic surveys.
MaxiWave was released in 2008 and was claimed by Sercel to be a technical milestone for the seismic industry. It was said to enable for the first time, without the use of specialized deployment equipment, large downhole arrays to be used for safe, efficient, and reliable recording of massive borehole seismic surveys either for standalone acquisition or in combination with 2D/3D surface seismic recording in both offshore and onshore environments. Designed for large downhole surveys, According to Sercel, MaxiWave features compact design, exceptional clamping force, and wireline telemetry, is ideal for hydraulic fracture and passive monitoring surveys, and is increasingly being used for shale gas application providing the user with the fast sampling and wide antenna aperture needed.
Mitch Peters, president, GeoStrata, said: ‘The MaxiWave is the tool of choice in an ever-expanding oil and gas market where there is a shortage of microseismic options for clients. We are considering a second system in 2011.’
