Seismic surveys are used to produce detailed images of the various rock types and their location beneath the Earth’s surface. This information is used to determine the location and size of oil and gas reservoirs.
A comprehensive introduction to the technical processes involved in drilling an oil and/or gas well.
Well logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole. The electronic log (E-Log) is based on physical measurements made by instruments lowered into the hole.
