In the XIX-XX centuries, it was impossible to imagine the oil and gas exploration in the pre-war period without field geological expeditions. In the second half of the XX century, the hammer as an instrument of obtaining new geological data was replaced by geophysical equipment. However, over the past 10 years there has been a tendency to renew the field study of target formations in outcrops. In this regard, the upstream companies organize long geological expeditions in the areas of exploration, both in the onshore and offshore projects (on adjacent land outcrops) for a period of 2 weeks to 2 months with the participation of their own and invited specialists. This is due to: A) The development and implementation of new laboratory methods of rock testing. Application of these methods requires the collection of new samples; B) The periodical appearance of new surface oil and gas seepages in regions with active seismicity and tectonic movements; C) The need to use the data of the structure and stratigraphy of target formations in outcrops with seismostratigraphic models to simplify seismic interpretation.
