2D/3D survey design

Prior to the implementation of a major 2D/3D reflection seismic survey a detailed planning of the survey layout and acquisition parameters should be realized. For the optimal imaging of a specific target area in the deep underground, a much larger survey layout at the surface is required, which considers the local topographic, geologic and geophysical conditions. The seismic acquisition costs can be significantly reduced by an optimal survey layout, focusing on the specific objectives and targets of the exploration mission.

For the planning of a new survey design all information of previous seismic surveys, wells and geologic maps will be integrated.

Our offer for the survey design includes

  • Analysis of existing knowledge
  • Calculation of area for the survey layout at the surface
  • Ray tracing
  • Presentation and discussion of various field layouts that fulfill the requirements of the specific exploration task, including a recommendation
  • Modelling of coverage maps with different offset ranges (Fig. 1 and 2)
  • Discussion of offset and azimuth distributions of different layouts
  • Modelling of survey scenarios with skips of shots and/or geophones due to access restrictions (e.g. nature reserves)
  • Optimization of the orientation of the source and receiver lines
  • Distinction between different seismic sources on-shore (Vibroseis, dynamite) and off-shore (air gun)
  • Summary of all theoretical shot and receiver points for cost estimation
  • Provision of theoretical point coordinates for the acquisition company

In addition we offer

  • Preparation of tender documents
  • Preparation of technical specifications
  • Evaluation and comparison of the offers from different seismic contractors
  • Preparation of an operating plan
  • Support and preparation of public information events
