         *Study: cross plots and colored section/ 3D body results                                                             

- AVO analysis (Gradient analysis, Intercept/Gradient, Fluid Factor - calculated in sliding windows to fit correct lithology mudrock line and other ...)

           *Study: cross plots and colored section/3D body results  

- Screening attributes 

           - “Sweet spots” package:  Relative inversion (1 volume) + Phase Decomposition (0 and 90 deg components)

                                                                                           + Prony Filtering (3 volumes) + Q-factor section

-Fault Sealing/leaking analysis support

           - Seismic Data Attribute Package (15 volumes)

- Seismic multi-attribute analysis on Paradise software package (Machine learning more than 50 attributes automatically analysis). 

- Rock Physics modeling (Logs, Fluid replacement modelling/substitution,synthetic gathers & reflection response modeling, wedge modeling, Rock Physics templates calculations and etc.)

- 4D geophysical analysis and interpretation    

                                        

Time

Typical size is 1000 km2 3D from field tapes with turnaround 3-6 months, or up to 3000 km 2D processing per month.

AVA analysis (including cross plots) - 1 day per 2D/arbitrary line.

Data preconditioning 1-3 days for Reservoir Evaluation. Fluid Replacement Modeling, synthetic gathers - 1 well per day.

Pilot version: Reservoir Characterization – from 3 days for 2D/arbitrary lines.
