In this short article we will cover the basics of seismic horizon interpretation and how this is used to obtain stratigraphic information. Other uses include mapping salt structures for their use as natural gas reservoirs (gas caverns), delimiting mineral deposits among other activities involving imaging of the subsurface. Recently, this type of data has also been used in geothermal energy activities, carbon sequestration in geological reservoirs and wind energy, especially offshore. 2D and 3D seismic data are major sources of information in the oil industry for both onshore and offshore activities. Reflection seismic is one of the fundamental ways of imaging the subsurface from a geological perspective. If you mess them up and don't find out till later, you will be very sad, but not as sad as your exploration manager.A Simple Guide to Seismic Horizon Interpretation fun) interpretation so they sometimes get brushed aside, left till later, rushed, or otherwise glossed over. Well ties are one of those things that get in the way of 'real' (i.e. Don't create multiple, undocumented, obscurely named copies or almost-copies of well logs and synthetics, unless you want your seismic interpretation project to look like every seismic interpretation project I've ever seen (you don't).
Don't tie wells to 2D seismic lines you have not balanced yet, unless you're doing it as part of the process of deciding how to balance the seismic.Get help before trying to load or interpret a VSP unless you really know what you are doing.Do not trust any checkshot data you find in your project - always go back to the original survey (they are almost always loaded incorrectly, mainly because the datums are really confusing).If you go ahead, read your software's manual. Be careful with deviated wells you might want to avoid tying the deviated section entirely and use verticals instead.
