YucatánSPAN

Until recently, understanding of the Mexican sector of the Gulf of Mexico has been based on 1970's vintage seismic data and processing. YucatánSPAN is a program consisting of newly reprocessed data that applies ION's RTM processing to the seismic grid originally acquired by University of Texas in 1978. The program covers Mexican waters, crosses the Yucatan platform and links to the FloridaSPAN survey with ultra-long lines that cross the entire Gulf abyssal plain.

YucatánSPAN will provide major advances in the understanding of the southern Gulf of Mexico's geology and its entire evolutionary development. Lines of the program reach eastward and tie to the southern FloridaSPAN lines. The reprocessing starts from field tapes and depth imaging is performed using RTM and Kirchhoff techniques. The initial results have demonstrated superior illumination of the deep crustal structure, salt and under-salt sediments, as well as the Cretaceous and Wilcox sediments.

Mexico Data Example

As seen in the key line below, features never before seen on public data are resolved. These include imaging of Campeche's basement step-up to the ocean crust and the basal thrust of the allochthonous Campeche salt front.

This YucatanSPAN line connects to GulfSPAN where the Tiber well is located. A major Wilcox deep-axis is in Mexican waters and crustal features show the Continental/Oceanic boundary detachment fault. Click on the image to zoom and pan over the data example.

This YucatánSPAN line connects to GulfSPAN where the Tiber well is located. A major Wilcox depo-axis is in Mexican waters and crustal features show the Continental/Oceanic boundary detachment fault.

This new dataset will revolutionize our ability to:

  • Document southern Gulf of Mexico marginal development
  • Perform crustal reconstructions with the northern Gulf of Mexico margin
  • Document the sedimentary filling history of the entire Gulf of Mexico
