Mexican Solutions for Seismic Studies

In recent years, Pemex has been allocating an increasing proportion of its investment budget to exploration activities in onshore and o†shore areas. In order to successfully identify new oil reserves and better exploit existing ones, Javier Núñez, CEO of Grupo Núñez, explains that Pemex must invest more capital in the acquisition of seismic data. “Pemex has seismic data on most of its fields, but in order to increase production, it must acquire more seismic data to better define geologic models and be able to identify the di†erent strategies and technologies needed to exploit the remaining oil reserves at mature and potential fields,” says Núñez. “If studies are performed and accurate seismic data is acquired, Pemex also has the potential to achieve early production and get an earlier return on investment.”

Capitalizing on these opportunities, Grupo Núñez, a Mexican company specializing in all seismic related matters, o†ers technical support in the acquisition of seismic data through the use of tools such as geophones and advanced exploration techniques such as gravity gradiometry. The company also o†ers technical support in all activities related to data acquisition.

The potential for seismic studies in Mexico is huge, due to the fact that there are vast onshore, shallow water, and deepwater opportunities. “The easiest fields to acquire seismic data, develop, and exploit are onshore fields. However, this does not necessarily mean that Pemex should be investing more resources in these fields,” explains Núñez. Despite the importance and number of onshore fields, he strongly emphasizes the urgent need to invest in seismic studies for shallow water fields, because past seismic studies and over three decades of production experience have demonstrated that shallow water fields have great potential due to their geology, accessibility, and Pemex’s experience in shallow water.

With regard to deepwater, Pemex has acquired vast seismic studies, but there is a need for more detailed data. “One of the ways to acquire this detailed data is through the use of techniques such as VSD massive and 3D studies, which would o†er Pemex more detailed information on specific areas where other fields have been discovered and more data on the limits and quantities of oil reserves,” says Núñez.

In order to obtain more detailed seismic data, Núñez believes the NOC should acquire more technologies from abroad. “Pemex needs new technologies like data acquisition from digital sensors, technology with the ability to analyze secondary waves (S-waves), and new high density technology for mature fields, which would allow Pemex to have a better understanding of underground geology, reduce the distance between seismic indicators, and allow them to better define the volume of the oil or gas reservoir,” explains Núñez. Besides needing all these stateof-the-art technologies to understand geological features of reservoirs, Pemex must invest in acquiring seismic data in a faster and more organized manner. Therefore, it must invest in a wireless transmission system, which is currently being applied globally and gives operators the ability to take real-time decisions and reduce costs.

Understanding the technological needs of Pemex and helping the company to bridge technology gaps, Grupo Núñez – through its alliance with Sercel and Bell Geospace – is making sure it acquires the best and most innovative technology worldwide and implements these in Mexico. Its main objective is to introduce the latest seismic technology available to Mexico through the various services o†ered to Pemex and Comesa, not only by selling the technology, but also through training, and ensuring that the technology is implemented correctly for the benefit of the country, Pemex, and Grupo Núñez’s clients. For example, the company operates a training and support center in Mexico City to ensure that its clients are able to maximize the impact of their technology investments.
