WAVE Knowledgebase

What is it?

The most sophisticated classification scheme + database available for fluvial and shallow marine depositional systems.

What is it used for?

Classifying modern and ancient marginal marine clastic depositional systems and providing analogue and dimensional data. Take a look at this satellite image of the Indus Delta in Pakistan taken during the afternoon such that water-bodies appear golden. At first glance most classify it incorrectly as a tide-dominated delta.

Note the abundance of tidal channels that widen towards the sea (top left)

The delta is always left-out on Galloway’s ternary classification plot.

Take a look at the satellite image, the increasing white on the towards the top-left are wave-reworked mouthbars

Even though it receives the world’s highest wave energy, the distribution of wave influence is not uniform along the delta front. At first glance the delta appears to be tide-dominated due to the abundance of tidal channels. So how would you classify the delta? and what difference would it make?

If this were a sub-surface example, then the classification would be used for reservoir prediction. Most will assume a wave-dominated delta will have a wide high net:gross strandplain with low risk for reservoir presence – but the Indus Delta has no strandplain whatsoever.

A better approach would be to classify the processes acting on individual lobes. The letters you can see in this picture on the active lobe tell you that it’s fluvial-dominated, wave-influenced and tide-affected.

The WAVE Knowledgebase not only helps you classify natural systems, it then predicts what facies associations and depositional architecture you can expect to find which would then lead to better reservoir and seal distribution prediction.

How can it help me describe core?

The WAVE Knowledgebase comes with modules that can aid in your core description by providing a large collection of core photos that show a wide range of sedimentary structures and trace fossils. Using these as a reference ensures you identify diagnostic features with confidence.

How would it add value to my business?

Let’s assume after using the WAVE Knowledgebase for interpretations. You realize you have drilled through a mouth-bar sandstone associated with a tide-dominated deltaic lobe – what is the size of the prize? What volume of sand can be contained in a mouth bar? That should matter because that will dictate what hydrocarbon volumes you are expecting from drilling more of these in future wells.

If you are correlating, it would be nice to know how far a sand-body would extend in a depositional-dip vs depositional-strike direction?

Do I need a work station to run it?

Not at all! in-fact you can use it on a laptop or a tablet.

Do I need to be an expert sedimentologist to be able to figure out the software?

Not at all! In-fact, the entire WAVE Knowledgebase concept is designed for the average asset team geoscientist in mind.

So you’re saying it is useless if I am an experienced sedimentologist?

As an experienced sedimentologist you will get to see what happens when you bring in “big-data” from modern systems and that too over multiple years. Some of the findings made by the WAVE Knowledgebase team especially when it comes to the evolution of mouth-bars in different process regimes are enlightening to say the least.

We have come a long way from simplistic models of mouth-bar evolution – you won’t find this stuff in the public realm
