The South Campeche Ultracube™ 3D Reprocessing project comprises approximately 15,900 sq km and is located in one of Mexico’s most prominent offshore exploration areas, with several proven oil and gas discoveries.

The Gulf of Mexico (GOM) is one of the most prominent offshore exploration regions and has become known for its salt associated discoveries and mega oil finds. The GOM has a long and complex depositional history and is extensive in size, attracting explorers from around the world. Abundant salt pillows and diapirs populate the subsurface resulting in a need for thorough and modern processing sequences to obtain accurate seismic imaging. The GOM contains multiple thick source rock intervals resulting in multiple petroleum systems throughout the region. The area continues to remain one of the most successful exploration provinces despite maturity as the drive for understanding the complex area and the hunt for the large variety of undiscovered play types continues.

The project is a merge of three existing surveys; the Holok Alvardo 3D (2003), the Cequi 3D (2010) and the Boloi Norte-Balche-Xulum 3D (2003).

The new 3D Ultracube extends over 260 km in the southern part of the Campeche Bay area and provides new depth imaging of the Southern Campeche – Sigsbee Basin and also parts of the offshore Comalcalco Basin. The southern part of Mexican Ridges in the Veracruz Basin are also covered by the new South Campeche Ultracube.

75% of the South Campeche Ultracube is located in waters less than 1,000 metres in depth; with the shallowest water depth being approximately 30 metres.

The project incorporates a very thorough pre-stack imaging and post-stack processing sequence staged in two parts. Firstly, the pre-processing produces high S/N ratio, broadband data and secondly, imaging using TTI Kirchhoff and RTM technologies to properly image the subsurface, often with extensive salt pillows and diapirs.
