Environmentally Friendly Seismic Source
eSource is a tunable, flexible seismic source which reduces the high frequency emissions that can affect marine life. Everyone working in the oil and gas industry is aware of the importance of…
Geophysics: A Simple Guide to Seismic Amplitudes and Detuning
Seismic amplitude changes may tell us something about reservoir lithology, porosity, and/or fluids. However, seismic tuning effects are potentially much larger than amplitude variations due to geological changes. Understanding this…
Little and Large
Seismic supply companies are helping operators face the downturn by providing cost-effective enhancements to existing product portfolios. With the oil price for this year staying at the low levels seen…
