Multiclient wide-azimuth survey begin in Campeche, Mexico

Sept. 17, 2019
A wide-azimuth survey covering 5,080 sq km started in the Salina del Istmo basin in Mexico’s Bay of Campeche, which contractor Schlumberger Ltd. said provides the first 3D coverage over this shallow-water target area, including the Zama-1 discovery.

A wide-azimuth (WAZ) survey covering 5,080 sq km started in the Salina del Istmo basin in Mexico’s Bay of Campeche, which contractor Schlumberger Ltd. said provides the first 3D coverage over this shallow-water target area, including the Zama-1 discovery.

The multicient project, WAZ-6, hired WesternGeco, the geophysical services and subsurface data division of Schlumberger. The survey will complement existing WesternGeco WAZ coverage, merging with other WesternGeco Campeche WAZ programs.

WesternGeco will use cloud computing power to accelerate processing with expected delivery to clients in late 2020.

The Bay of Campeche is a geologically complex area, said Maurice Nessim, WesternGeco president. “We have acquired and processed more than 72,000 sq km of new WAZ data and reimaged around 95,000 sq km in the Campeche basin alone,” Nessim said.

A range of advanced imaging technologies will be applied to improve reservoir continuity and ensure reliable amplitude and quantitative interpretation analysis, which reduces predrill risk and increases exploration success.
