Application of interpretation technology of salt-related trap in deepwater compression area offshore Burgos Basin, Mexico

The Gulf of Mexico is famous for its rich oil and gas resources. Salt related trap verification is the key issue in basin exploration. Therefore, it is necessary to establish an effective comprehensive interpretation technology. Taking Burgos Basin as the research area, based on seismic, well-logging, and gravity data, the petrophysical properties of salt was studied, after which a set of key technology for salt-related trap interpretation was summarized considering the seismic reflection characteristics of shallow allochthonous salt, deep autochthonous salt, salt feeder, and surrounding formation The technological package includes double-layer salt identification and analysis technology, multi information fault interpretation technology based on seismic and physical model, full 3D horizon interpretation technology based on marker horizon constraint, and salt model discrimination technology based on the integration of processing and interpretation. By applying the technology set, several key targets were interpreted accurately, which is proved by drilling at the A trap with an oil discovery. Therefore, the multi-technology approach can be used as a reference to salt-related trap interpretation and analysis in other similar salt basins.
