Techniques (Interpretation)
Got your interpretation picked? Explore techniques to get the most out of your data. Clean up a horizon in minutes, estimate a quick area/volume calculation of a prospective reservoir, or highlight possible faults segments. This section is full of great interpretation tips.

Picking horizons across surveys
Instead of picking horizons for your 2D then picking the same event separately on your 3D, why not interpret them all at once? DUG Insight picks across multiple surveys in the same horizon.

Getting picky with phase!
Instantaneous phase is great for highlighting changes along events and increasing apparent resolution, but it can be a real pain to interpret! With one quick calculation, we can make it much easier to work with. Check out this great approach to finding the cosine of instantaneous phase using DUG Insight’s instantaneous attribute and volume maths processes.

Faster, Better Fault Interpretation with Arblines
Arblines are a great aid for picking faults and perfecting your interpretation. DUG Insight adds some great workflow enhancements to arblines that solve common problems and help get the most out of your data.

Highlighting Structure and Identifying Faults
Identifying fracture patterns, stratigraphic changes and delinating faults can be difficult without the right tools. DUG Insight’s structural attributes highlight discontinuities and even curvature in a seismic volume. Find out how these tools work, how to configure them and when to use them. It IS your fault, but it doesn’t have to be a problem!

Structural Curvature
Heard about curvature, but not sure exactly what’s being described? Get your nerdy cap on and read up on DUG Insight’s approach to the curvature seismic attribute. How is it calculated? What does it mean? Find out all the maximum positive curvature secrets and get the most from your interpretation.

|
Cleaning up Horizon Interpretation
Use Insight’s horizon operations to remove gaps, unnecessary spikes, and create geologically sensible horizons. Quickly create a polished product that’s perfect for use in Insight processes and stratigraphic flattening. Well-defined Isopachs, accurate amplitude extractions and reliable volumetrics are all a few steps away.

Exploring Sequence Stratigraphy
Understanding stratigraphy is essential to prospect development, particularly in identifying risk and uncertainty. Use DUG-Insight to interrogate data, identify key surfaces and system tracts, and build dynamic stratigraphic models or pseudo wheeler diagrams.

|
Calculate proportional slices and layer attributes
Sometimes scanning an interval with time-slices just doesn’t cut it. Learn how to create iso-proportional horizons through a reservoir interval and extract any attribute you need!
|
|
|
Quick area/volume calculations
Need a fast estimate of a prospect’s size? Use Insight’s Geometry tools to run quick calculations of area and volume.
|
|
|
Volumetrics
The Volumetrics Wizard can calculate the total volume of a structure, the contact area, and generate area-depth pairs by using just a top (single) or a top plus a base (dual), and a flat contact.

How to Combine Fault Polygons
Got a bunch of polygons, but the program will only let you pick one? Merge as many polygons as you like using DUG Insight’s polygon combine option Now you can regrid, smooth and interpolate with style!

Automatic gather picking from a 3D horizon
For years, gathers have been too large (and slow!) to use in every-day interpretation. These days, we shouldn't think twice about turning to gathers to understand AVO and anisotropy. In this DUG-Insight workflow, we show how to use a 3D (IL/CL) horizon to automatically pick an event through some gathers.

Exploring Sub-Zero Attributes
Exploration doesn’t stop for Christmas! Get the most out of seismic and structural attributes to identify hidden features within your seismic. What will DUG-Insight help you find this festive season?
|
|
|
Mapping Conformable Events using Well Markers
Keep the conformability in your geological horizons even when data is sparse. DUG Insight’s horizon conformance mapping technique is a handy tool for resolving well-picks and depth converted horizon residuals or picking a conformable horizon in a deeper noisy data area.
|
|
|
Merging Horizons
When working with vintage data, combining old and new interpretation is a requirement… but how do you merge horizons from different 2D and 3D surveys? DUG Insight’s horizon tools include a one-line command to merge horizons. It’s an easy way to combine local and regional interpretation into one, easy-to-use result.
|
|
|
Clipping Horizons and Surfaces
Building a geological stratigraphy model? Need cleanly truncated surfaces that stop at key boundaries? Find out how to use horizon maths to quickly clip surfaces for building the perfect model. Once again, DUG Insight’s easy-to-use formulas come to the rescue!
|
|
|
Correct Interpretation to Tie Seismic Events
We’ve just received some data from another interpreter and it’s not looking good. The horizon doesn’t tie our seismic! We don’t want to throw away all this careful work, so we’ll need to update this interpretation. Find out how to easily tackle this problem using DUG Insight!
