Geophysical operations
The IOGP’s Geophysical Operations Subcommittee monitors and identifies the need for industry guidelines or standards for exploration, development and production related geophysical operations, with the objective of recommending good industry practice to improve the safety, quality and efficiency, and to develop new guidelines and standards as required. Specific areas of interest include:
- Positioning for geophysical operations, especially seismic surveying, on- and offshore
- ‘P’ geophysical position data exchange formats (P1, P2, P6)
- Drilling hazard site and development route geophysical surveys
- Geophysical instrumentation such as Multibeam Echosounders, Sidescan Sonar, Sub-bottom Profilers and Magnetometers, where they are used for seismic and drilling hazard site surveys.
We promote continuous improvement in the quality of geophysical data used to assess drilling or development risk due to shallow / seabed hazards and also in seismic positioning, in support of increasingly demanding geophysical objectives and the developments in acquisition techniques necessary to achieve them.
We maintain the following IOGP Geomatics Committee guidelines and data exchange standards through regular reviews and document updates in accordance with the IOGP requirements, either in direct control or through temporary Task Force(s):
