How well do we predict depth?
Observations from systematic depth conversion reviews and the impact on the drilling portfolio.

Presented by Guido Hoetz, EBN.

Systematic well reviews are essential for improving on future drilling performance. The accuracy of depth prognosis results has being analyzed in detail by EBN using an extensive dataset; 253 recently drilled petroleum wells in the Netherlands. The outcome reflects uncertainties in seismic interpretation and -more importantly- velocity models. The data indicates that the predicted depth at reservoir level shows an uncertainty of 1.2% (1 sigma). Also a clear bias towards predicting too shallow is evident from the dataset. A possible explanation based on the mechanism of selection bias is being presented.

From Seismic to Rocks - seismic interpretation advances in the last 10 years
Presented by Stephane Gesbert, Exploration Technologies Shell Global Solutions International B.V.

In the past 10 years, the E&P industry has developed novel Seismic Interpretation technologies to get "more geology out of seismic data." At Shell, the development effort was originally driven by the need to robustly identify and de-risk stratigraphic traps in seismic data, but turned out to have broader appeal and impact. A central articulation of this capability is (1) the rapid interpretation of an arbitrary number of wall-to-wall seismic horizon. In turn, this dense stack of horizons enables (2) seismic attribute mapping at all stratigraphic levels. Finally, the classic offering of seismic attributes has been augmented with (3) novel attributes to characterize and visualize seismic stratigraphy to an unprecedented level of detail.
In this presentation, we will review these key elements of modern 3D Seismic Interpretation, illustrate them with recent case studies, discuss current challenges and the road ahead.

Prehistoric humankind adapted to changing sea-levels, so why can't we?
Salomon Kroonenberg

About 120,000 years ago, the surface of the sea was six metres above where it is now. When Neanderthal people on the Channel island of Jersey discovered that the source of flint for their stone implements became flooded, they turned to quartz, and when sea level dropped again they returned to flint, because it was better raw material.

The staple food of South African Homo sapiens during the Eemian highstand was black mussels, a species that lives clinging to the rocks in the surf. When sea level dropped and the rocks fell dry, they changed to white mussels, a species that lives in the beach sand under the waterline. If our ancestors over 100,000 years ago could adapt their staple food and mineral resources to changing sea levels, why wouldn't we be able to do so?

During the coldest part of the last Ice Age, 20,000 years ago, people lived on the dry bottom of the North Sea. When sea level started to rise in the Late Pleistocene and Holocene, they adapted by steadfastly moving their dwellings landwards - probably except those living on Doggerland, which might have drowned indeed.

Over the last six thousand years, sea level has been relatively stable, and global tide gauges do not show any acceleration in sea level rise since the end of the 19th century up to the present day: global sea-level rises at ~20 cm per century. Alpine, Alaskan and Arctic glaciers are still longer than they were in Roman and Mediaeval times, showing that their present retreat is still within the range of natural processes. There is nothing "unprecedented" in sea-level rise so far. Considering how inventive our ancestors were at adapting to sea-level changes with the paltry means at their disposal, we should not worry about our ability to do so in the future.
