With today's prolific use of 3-D seismic in property evaluation, you need a seasoned 3-D seismic interpretation geophysicist who:
✔ Understands the data and the database.
✔ Knows the "tricks"and shortcuts of the software for efficient workflow.
✔ Recognizes interpretation pitfalls and knows how to avoid them.
✔ Can generate precise structure and seismic attribute maps integrated with your geologic and engineering data to enhance your property evaluation.
✔ Is a team player, on your side.
