Seismic Acquisition Design & QC
Acquiring high-quality seismic data requires innovative solutions to the many acquisition challenges that occur in land, transition zone and marine environments. Seismic surveys can be acquired in a safe and environmentally friendly manner when the proper planning, design and field management techniques are employed.
Optimizing a seismic survey to meet and surpass the proposed objectives is paramount to a successful exploration program. To meet this goal, TANA uses our geophysical expertise and a variety of commercial software packages to model and design the survey. Once the modeling is complete, a seismic survey is designed which will optimize the calculated parameters and most accurately image the geologic target.
We check your basic survey parameters like target depth, dips, area size, required resolution, calculate fold and offset distribution and develop a custom made Survey Design.
Field quality control of data can eliminate many potential problems with the processed data set. To provide comprehensive quality control, PPZG's experts have broad experience including land, marine and transition zone acquisition.
2D & 3D Seismic Data Processing
The level of sophistication of today´s geophysical analysis toolkit requires that more focus be placed on the quality of the seismic data that is being used. PPZG provides full-cycle seismic processing and imaging that is designed to provide the client with the most robust data possible. PPZG provides a full service 2D and 3D processing capability to address the most difficult exploration or production problems faced by our clients.
Processing being performed by TANA is aimed to receive maximal time resolution, to increase signal/noise ratio and to define dynamic response and velocity characteristics of the subsurface.
Also, TANA offers Quality Assurance and Quality Control (QA/QC) services for those clients that do not have the internal resources to ensure high quality contractor processing results.
TANA has well-defined processing standards for preserving amplitude and phase information, stratigraphic information and structural information. QA/QC services will directly affect:
- Amplitude and phase of the seismic data
- Resolution of subtle prospects
- Structural /Stratigraphic interpretation
- Geopressure prediction
