UK MNSH 47
Complex faulting, unconformities and terminations, carbonate platforms and salt structures.
This example is from a central portion of Line 47 from the UK North Sea Transition Authorities “Mid North Sea High” dataset. The data is used by permission.
The target zone is carbonate platforms in the Zechstein formation (purple). Other potential targets exist throughout the upper section.
Start your transition here
By visiting this page and downloading the project, you start transitioning from interpreting seismic data through attributes (like color or gray) to directly interpreting seismic data itself. This is a transition that you along, with everyone else in the industry, must undertake. The transition is remarkable, comparable to the shift from single-fold analog seismic to multi-fold digital seismic over sixty years ago. Just as that transition challenged everyone’s understanding of what seismic can reveal about the subsurface, this one will too.
The project contains a short segment of a single seismic line, taken from the UK NSTA’s Mid North Sea High project. Even though it’s just a segment of a much longer line, studying it first will give you an idea of what to look for in our more detailed example projects and in your own seismic data.
Start by reviewing the comparisons provided on this page. Then, use StratiScape to study them in detail. You are stepping into a new world. Get ready to be amazed..
UK NSTA Mid North Sea High Line 47 Comparison
This is a small section of a much larger line and contains only the central portion of the line. The complete line is part of our Mid North Sea High example project. This portion of the line, however, is interesting because it contains significant amplitude anomalies in the lower Zechstein event plus complex faulting, unconformities and terminations.
Being a short line, it is the perfect place to start your transition.
Here are a few more things to look for
Enhanced Fault Visibility
Visualizing and understanding fine scale fault details is an essential element of any interpretation. Notice how much clearer and more distinct the fault plane reflections are on the StratiScape image.
Dual Polarity display comparison
The left image is our dual polarity display that shows negative polarity events in green and positive in white. It is exceptional at highlighting changes in both positive and negative impedances.
Amplitudes and pinchouts at an unconformity.
Notice the amplitude details and the clarity of the terminations on the StratiScape image.
Ghost Events
A problem with greyscale images is that low-amplitude events appear ghosted and hard to follow and interpret. Notice how these events now stand out on the StratiScape image.
