Seismic survey design

  • Survey design

  1. Determination of the main geological tasks and objectives of future exploration in the seismic survey area;

  2. Analysis of baseline geological and geophysical data both in the survey and surrounding areas;

  3. Shooting parameters calculation according to the stated requirements;

  4. Creation of the «ideal» shooting scheme based on the calculated parameters.

  • Modeling

  1. Structural 3D model creation of the seismic survey area;

  2. Calculation of interval velocities;

  3. Velocity model creation;

  4. 3D ray-trace modeling;

  5. Model results analysis, illumination and fold maps building based on common reflection point;

  6. Modifications of the seismic survey area size (as needed).

  • Scouting

  1. Determination of obstacles of natural and man-made origin directly at the site of work that thereafter will make changes to the «ideal» shooting schem – the so-called «blind» zones determination.

  • Optimization

  1. Modifications of the «ideal» shooting scheme based on the scouting, that is, shifting and relocation of receiver and source points according to the existing surface obstacles and conditions;

  2. Real shooting scheme creation;

  3. Remodeling based on a newly created real shooting scheme.

  • Final shooting design

  1. Consolidation of the results of all previous processes, final project creation;

  2. Approval of the work program, transfer of available materials to the customer.

Seismic survey supervision

BREND-VIC LTD provides consulting services and supervises all types and stages of seismic acquisition projects. Our supervisors are highly qualified specialists with an extensive experience in field operations in a variety of natural, climatic and seismogeological conditions with vibroseis, explosive and pulsed types of source, telemetric and cable-free nodal recording systems.

  • Tender support

  1. Preparation of the technical part of tender documentation;

  2. Development of requirements for equipment and personnel;

  3. Analysis of the participants' technical and production capabilities in terms of the possibility of solving a geological problem;

  4. Technical audit;

  5. Development of the quality requirements;

  6. Audit of the contractor's seismic survey quality management system and making it consistent with the project's goals and objectives.

  • Supervising

Supervisors perform their activities in close cooperation with the contractor's specialists, ensuring the achievement of a common goal - the successful and quality completion of the project with a strong technical and economic indicators.

  1. Preplanning of the experimental and methodological program, the program result's analysis, and seismic survey parameters selection;

  2. Readiness evaluation of the contractor's crew to carry out field operations;

  3. Quality control (QC) of seismic acquisition and surveying;

  4. Supervision of the contractor's HSE performance;

  5. Participation in planning of field operations, providing recommendations on work optimization;

  6. Support with operating interaction between the customer and the contractor on issues related to the implementation of the project;

  7. Data quality control (QC) and data acceptance;

  8. Confirmation of the scope of work performed;

  9. Deliverables quality control (QC) for further transfer to the client;

  10. Comprehensive reporting to customer on quality and scope of work performed.
