As hydrocarbons are becoming more difficult to find and to produce, operators who utilize relevant advanced technology have a clear advantage. What is not always clear is which advanced technology is relevant or applicable in a given situation. If we look at developments in land 3D seismic surveying over the last few years, we see a dramatic increase in the capabilities of the equipment being used and also innovative methods of its usage. We have seen significant increases in the trace densities of surveys and the recording intervals have been decreasing accordingly, but at what trace interval do we cease using geophone arrays and start using point receivers? Should these receivers be vertical component (1-C) sensors or multicomponent (3-C)? Should we use capacitance-based MEMS sensors or induction-based moving-coil geophones? Finally, advances in electronic systems now permit recording data without the use of telemetry cables—either by transmitting the data back to the recording truck by radio for quality control purposes and immediate storage on tape or discs or by storing it locally at the receiver for later recovery. Are there circumstances where there is a significant benefit from the utilization of a cable-less system as opposed to one with cables? This paper will discuss some geophysical and operational factors related to these questions.
