Is specialized in the reprocessing and review of geophysical surveys acquired by other companies. Numerous public and private clients rely on our specialists for technical assistance in the field of geophysics. The proven experience of our technicians, the application of standardized protocols and norms, as well as the use of algorithms and specific tools developed in collaboration with our external consultants, have earned us the trust of our clients.
The ZISSOU GEOPHYSICS team has extensive experience in handling digital databases and asset management. Some of the projects we participate in include the reprocessing and reevaluation of geophysical services provided by third parties, serving as an independent quality control service that ensures and validates the proper execution of geophysical campaigns worldwide.
After carrying out the full reprocessing of geophysical data—including editing, gridding, leveling, and filtering—ZISSOU GEOPHYSICS delivers to its clients a set of revised and integrated datasets. We are also capable of acquiring new data to complement historical surveys and generating complex models that reveal spatial relationships among different parameters. These outputs can be delivered as georeferenced images, viewable through geographic information systems, where they can be integrated with the client’s existing models.
Compared to traditional sampling methods, geophysical approaches are particularly suitable as they minimize fieldwork execution time, associated risks, and economic costs, while maximizing the amount of data, information, and knowledge obtained.
To obtain appropriate geophysical information, our specialists consider several premises: site accessibility, required permits, proper data acquisition, and quality control. Quality control includes a series of subprocesses throughout the study, such as emitter and receiver positioning, identification of noise sources and interferences, biases that may affect subsequent processing or model parameterization, among others.
These processes require the development of specific protocols in the design of geophysical campaigns to determine possible error sources, identify noise and interferences, check inconsistencies among datasets, and perform in-situ preprocessing of signals. Quality control may also include access limitations to survey areas, risk assessment, and other safety requirements. Additionally, available resources (personnel, field equipment, or budget) must be considered, along with issues such as safety, civil liability, insurance, training, licensing, and customs.
We are ready to assist you at any time.
