Around the world, we are in an age of increasingly more stringent challenges for seismic acquisition to meet regulatory requirements. Meanwhile, the acquisition of geophysical data has become increasingly more diverse, with a broad range of operational practices and technologies utilized. Regulatory and environmental issues are assuming a key driving role in seismic source design, in source strength, in footprint/impact of surveys, and other ways. To meet evolving requirements, creative new technologies and practices will be needed. There are a number of highlights in current seismic acquisition technology trends:

  • There is an ongoing trend to more channels, with evolution towards point source and receivers
  • There are numerous nodal and cabled recording systems available for various deployments onshore, in transition zones, and on the water bottom
  • Vibrators have improved low and high-frequency outputs, and distortion is much reduced
  • High productivity vibroseis surveys utilize various sweep coding techniques for simultaneous sources
  • Ocean bottom seismic can be acquired in a number of different ways, with efficient handling of cables and nodes, including operations in very deep water
  • Marine streamer surveys include techniques with dual sensors and varying depths to improve low frequencies, suppress multiples, and operate in difficult sea conditions
  • Vessel capacity and streamer counts have grown, and data can be reconstructed between streamers with dual sensors
  • Streamer steering and enhanced 4D repeatability is improved. Wide azimuth multivessel geometries and circular/coil geometries enable imaging of extreme structure
  • Utilization of buried arrays, permanent reservoir monitoring, and 4D surveys continues to grow
  • Microseismic monitoring of fracking is routinely done with downhole and/or surface recording
  • There is also a growing need to monitor induced seismicity
  • Fiber optic sensing including distributed acoustic sensing is being deployed

This course provides the broad technical background for these highlights, and for the creative design of surveys to proactively address regulatory and environmental requirements. Participants are encouraged to bring along information and questions regarding any special or unusual surveys from their experience.

"Liked the characteristics and parameters of modeling sound. I also enjoyed seeing photos of various vessel setups and equipment." - Geologist, United States

"General sense of overview it gave me, and those aspects of course that gave a picture of actual operations and scale of operations. Instructor very knowledgeable, good communicator - really excellent." - Wildlife Biologist
