There is no such thing as a "standard interpretation". Each project requires detailed discussion with the client geologists to understand their goals. The interpreter needs to be flexible once the data is loaded and the geology is revealed. We use all the data that is available to us, including public domain and client in-house data.

Mapping:

• TWT/Depth Maps
• Regional Maps
• Detailed Fault Maps
• Play Fairway and Show Maps
• Prospect Mapping
• We still hand contour sometimes!

Software:

• IHS Kingdom Plus
• RSA Attributes
• Petrosys Mapping
• DUG Insight
• Other customised tools

Energeo has designed many surveys both 2D and 3D. Survey design requires both a geophysical and geological perspective. The parameters for underground mining at 200m are quite different to exploration targets at 2000m.

We are often asked "How much does it cost for a sq km of 3D or a line km of 2D?". This type of question never has a simple answer. Our main aim is to produce a good interpretation product, and this is always the main consideration in design.

Energeo can help with:

• Bid preparation and tender review
• Source and receiver type
• Source and receiver density (line spacing and station interval)
• Parameter testing
• Parameter Optimisation
• Acquisition Liaison (surveys never go exactly to plan)
• Processing Supervision

Energeo can build datasets large or small. Data verification and management isn’t the most glamorous aspect of being a geoscientist but it sure is important. There are many software tools for creating databases but the integrity of the data depends on people loading and caring for it.

Database experience:

• Largest contractor in GSQ’s Seismic Header Update SHUP project managing 25,000 2D files and 300 3D files
• Seismic Interpretation Database using Kingdom for GeoScience Australia
• Database of in-house SEGY using MapInfo and GoogleSheets for Arrow
• Petroleum well database using PPDM model for Origin

Software:

• Google Sheets
• MapInfo
• Seisee
• Seismic Toolkit
• SEGY Explore
• LAS Manager

A lot of tasks we are asked to do don’t fit neatly into a particular category. You might need a relational database or simple index maps. There is also a on-going need to convert data from one software/projection format to another. We have a variety of tools to accomplish this and, importantly, we understand what we do.

Software:

• MapInfo Pro
• Global Mapper
• Rockware
• Google Earth
• Energ-I-O (in-house toolkit for data conversion)

Seismic Interpretation should never be done in isolation. There is always some other geological or geophysical data that can be used to compliment the seismic and improve the geological model. Before starting any interpretation work we look for any open file data and ask you check your filing cabinets for any data.

Geophysical Experience

• Open File Seismic
• Other Geophysical datasets (e.g. TMI, Radiometrics)
• SBEA Mapping (Surat Basin)
• NGMA Mapping (Cooper/Eromanga Basins)
• Lidar
• DEM

Geology Experience

• CSIRO Bowen Basin Super Model
• Bowen Basin Solid Geology
• Imagery
• Weathering Information
• Surface Geology

Depth conversion is an integral part of seismic interpretation. Grid based depth conversion is the simplest form, where a TWT map is multiplied by a velocity grid to produce a depth grid. Beyond this it gets more complex. In an area with limited borehole control seismic stacking velocities may be used. We can also generate depth converted SEGY data for loading into other packages (e.g. WellCad).

Software:

• Petrosys
• IHS Kingdom Plus
• SEG Depth Converter
