ExploCrowd Lectures 

The ExploCrowd Lectures are free and open for everyone interested, since developing and maintaining competencies within the exploration community is high priority to us. Especially during a downturn.

We work to ensure competence building and continuity for our own people, collaboration partners, customers and those who are unfortunate to have lost their job, which is why we are offering lectures in the basic concepts of exploration. These ExploCrowd Lectures are for all explorationists, both those who work in oil companies, those who have retired, graduates, unemployed and others interested in learning a bit more than they already know - and get inspired.

Though we are often busy and not always living up to our target, we are aiming at planning a lecture for every month and encourage especially young people to join us for scientific snacks and good discussions.

Chalk Exploration

Maj Wendorff from Denmark & Sidsel Lindsø from ExploCrowd

In Norway, the Chalk section is often considered a Cretaceous interval that must be penetrated on the way to the more attractive Jurassic sand sections below. However, after four decades of production of Gullfaks in the northern North Sea, it was found that the Chalk above the Jurassic interval could be produced, and the main exploration target in Denmark is the milliDarcy Chalk, so is there something we are missing here?

Those are the topics of the Lecture:

  • The Fundamentals of the Chalk Play

  • Exploring the Classic Chalk Play

  • New Concepts and Renewal of Existing Models

When: Wednesday the 6th of February 2019 at 13.00-14.30


Unlocking secrets of the milli Darcy chalk

Efficient technology integration in Exploration

Sidsel Lindsø from ExploCrowd

As there are fewer explorationists to deliver upon the tasks we will need to find more efficient ways to work - and especially integrate new technology across the fields of geology and geophysics. At this lecture, we will go through efficient work methods to ensure integration of seismic attributes and spectral decomposition in the daily work, using the latest cutting edge technology from GeoTeric, PaleoScan and DUG Insight.

Join us and get inspired on how you could improve your ways of working.

When: Tuesday the 22nd of January 2019 at 13.00-14.30

Matt Hall, Agile* Scientific

Skills Required for Digital Geoscientists.

"What are the big problems in geoscience that we can tackle with machine learning?"

After hosting hackathons and discussing the topic with many different audiences, some themes are emerging according to Matt. It is interesting to discuss what it is that makes geoscience especially challenging when we're trying to solve machine learning tasks.

At this ExploCrowd Lecture, a brief introduction to Machine Learning applications for geoscientists will be covered, and we’ll have a good and open discussion about the skills we're going to need to meet these challenges.

You can also bring your own ideas and work challenges (ideas for improved efficiency along, and we’ll debate them at the meeting, providing different views and giving feedback.

This ExploCrowd // Agile* Lecture will provide foundation for all geophysicists, geologists, and subsurface scientists not only to understand the great potential and current use of Machine learning, but also prepare for the Force Hackathon (18th to 20th of September) and the Force Symposium 20 September.

When:    September 17, from 13 to 15.

Where:   ExploCrowd Offices, Business Center Stavanger, Reidar Berges Gate 9, 3rd floor. 4013 Stavanger

Recommended parking:  Jorenholmen Parking

Well Expertise for ExploCrowd.png

Drilling for Explorationists by Mike Simpson from Well Expertise.

In many organisations, the exploration department and drilling team are separated, but it often the case that a significant amount of time and cost can be saved through early integration of the disciplines.

Mike Simpson from Well Expertise will share his experience, and some examples of the frustrations that naturally arises when combining the conceptual thinking of the exploration geologists with the high level of detail and exact numbers required by the drilling engineers for the exploration well planning. He will give his advise on how to best prepare the mindset of the explorationists for this challenge when going prospect hunting.

Mike Simpson has a background in drilling exploration wells for small operators, including several first time operators and is the founder of Well Expertise, which started in late 2016 and has successfully assisted clients in delivering efficiently operated exploration wells at a cost below 200 million NOK in the North Sea.



Ivan Van Bever Lecture 12_12.png

Ivan Van Bever

Geoscientist at ESTIMAGES Norge AS.

Depth Conversion Models using 3D Geostatistical Methods for Improved Accuracy.

Velocity models are used for a wide range of applications. Time to depth conversion is one of the main and most important applications of velocity models. There are a lot of different ways of building velocity models depending on the scale (field, survey or basin scale) and the methodology used. Geostatistical solutions are also used in different ways when building velocity models for time to depth conversion.

This lecture will explain how geostatistics can be used and applied in the building of regional velocity models, from the qualification and conditioning of seismic velocities to the calibration of seismic velocities to well data and the estimation of uncertainties attached to the velocity model. Theoretical concepts and case studies will be used to give an overview of geostatistical tools (experimental variogram, variogram model) and techniques (factorial kriging, kriging with external drift, geostatistical simulations).

Peter Szafian, Principal Geoscientist at GeoTeric  
Colour blending in seismic interpretation: frequency decomposition, edge detection and multi-attribute analysis

There are several approaches that an interpreter can utilise when comparing different seismic attributes. A very powerful tool is explicit encoding, whereby different attributes are combined into a new volume, which simultaneously shows all the information from the input data and their relationship. As the most commonly used explicit encoding technique is colour blending, we will discuss methods that rely on it: frequency decomposition (RGB), combination of edge attributes (CMY), and blends that involve rotary attributes, such as azimuth (HSV). Explicit encoding helps us to simultaneously visualise dip and azimuth, while opacity blending enables us to compare four data sets. Examples from case studies will show how the intuitive use of these techniques helps interpretation and our understanding of geology.

Peter Szafian joined GeoTeric good four years ago, currently holds the position of Principal Geoscientist.

The Barents Sea carbonate play and geomorphologies revealed by spectral decomposition

Carboniferous to Permian carbonates and evaporites have long been known in the Norwegian Barents Sea, but little is understood about the prospectivity of these plays. Within the last year, the promising potential source rocks within the Gipsdalen Group have been promoted at several conferences, and the carbonate play has been promoted for the 24th Consession Round in the Barents Sea.

With new technology and old data, carbonate expert Tore A. Svånå and geophysicist Gustavo Lopes are joining forces to put geomorphologies observed in spectral decomposition into a regional context.

NEW location: ExploCrowd office, 9 Reidar Berges gate, Stavanger (dvs. 3 etg. Stavanger Business Centre)    
Time: 0830-1000

Syed Fakhar Gilani, Exploration Geophysicist in ExploCrowd
Seismic Well Tie within DUG Insight

Often in exploration, for various reasons there is not enough time, suitable software or the right people available to help to tie well data to seismic data, which is unfortunate since it reduces the level of confidence. We therefore hosted a Lecture addressing Seismic Well Tie, demonstrating why it is important and how it can be done in DUG Insight 4.

The lecture included how to investigate the seismic polarity and the phase of the seismic data, quality assurance of well logs, calibration of sonic and density logs, pitfalls for seismic well tie workflow, extraction of the wavelet and the optimized seismic display options for vertical and deviated wells within DUG Insight.

Syed is an Exploration Geophysicist with more than 20 years of experience in seismic interpretation, seismic well ties, velocity analysis and depth conversion. Furthermore, Syed has worked extensively with applied low-frequency analysis and spectral decomposition within exploration.

Bill Shea, CEO of Sharp Reflections
Understanding Seismic Data Quality with Pre-Stack Gathers: What interpreters need to know.

In this lecture, Bill gave a brief introduction to pre-stack seismic, and the growing role it plays in data quality assessment, AVO studies, and pre-stack inversion. He showed how multiples and seismic velocity errors can degrade seismic data quality, and how these problems can be corrected with pre-stack software tools. He also highlighted the practical advantages of integrating processing, forward seismic modeling, and amplitude interpretation in an integrated seismic reservoir characterization workflow.

Dr. Bill Shea is co-founder and CEO of Sharp Reflections, a fast-growing provider of quantitative seismic data analysis solutions. Bill is a recognized 3D seismic interpretation expert, and an advocate for increasing the use of pre-stack data for interpretation.
