Searcher Seismic in 3D seismic reprocessing project offshore Mexico

Searcher Seismic, an independent multi-client company, has announced the South Campeche Ultracube 3D seismic reprocessing project offshore Mexico, merging three existing surveys. 

The seismic project, totalling approximately 17,700km2, is a merge of three existing surveys, the Holok Alvardo 3D (2003), the Cequi 3D (2010) and the Boloi Norte-Balche-Xulum 3D (2003).

Rachel Masters, Global Sales Manager for Searcher, said the project is located in one of Mexico’s most prominent offshore exploration areas, with several proven oil and gas discoveries.

“The new 3D Ultracube extends over 260 km in the southern part of the Campeche Bay area and will provide 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.

“An important factor to note, in this low oil-price environment, is 75% of the South Campeche Ultracube is located in waters less than 1000 metres in depth; with the shallowest water depth being approximately 30 metres,” Masters added.

The South Campeche Ultracube includes coverage of areas in Rounds 2 and 3.

According to the company, the project incorporates a 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.

ARES B approval has been granted and processing of the project will start shortly, the multi-client company said.

Searcher added that fast track products would be available in approximately 6 months, and final volumes in the second quarter of 2017.
