Tasks to be solved:

Supervision and field processing of seismic materials

Drawing up design schemes for processing areas of 2D and 3D, selection of work methods, field processing of 2D, 3D data, monitoring of the design of the survey and the quality of the received seismic data. Participation in the preparation of reports on field work, delivery of materials to the Customer, in territorial funds.

2D, 2D / 3C, 3D, 3D / 3C seismic processing

Processing is carried out while maintaining the true ratio of amplitudes and allows you to get high-resolution and informative time sections and cubes of seismic data of various modifications.
Within the extended processing graph, the following is performed:

• migration before summation in the time domain;
• migration before summation in the deep region;
• AVO analysis;
• amplitude and elastic inversion, obtaining sections and cubes of impedances of P and S-waves.

Interpretation of seismic data

Detailed mapping of oil and gas traps

• clarification of the contours of oil or gas fields;
• forecast of lithological-facies variability of reservoirs;
• determination of the reservoir properties of the productive intervals of the section in the interwell space;
• construction of detailed digital models of oil and gas fields.

VSP data processing and interpretation

High qualification of specialists, the availability of modern equipment allow us to solve the following geological problems that arise at the stages of exploration, development and operation of deposits:

• determination of seismic parameters of the environment;
• prediction of the geological section deeper than the bottom of the well;
• study with increased detail of the structural features of productive intervals in the near-wellbore space, assessment of the lithological features of productive intervals in the near-wellbore space.

Geological and hydrodynamic modeling

• refinement of reservoir parameters for interpretation of well logs and petrophysical core studies;
• replenishment of the geological model with data from production drilling in the modeling process;
• collection and analysis of field information on wells and deposits during operation;
• construction of a geological and hydrodynamic model of the field;
• adaptation of the geological and hydrodynamic model to the history of field development.
