The GWC is an annual competition that brings together geologists from around the world to showcase their skills in steering unconventional and conventional wells.
Participants joined from all over the world
Charlie Lake Formation Reservoir
The Charlie Lake Formation is a complex unconventional reservoir, with cyclic deposits of dolomite, anhydrite, siltstone, and sandstone. Precision geosteering and hydraulic fracturing are essential to overcome low permeability and optimize production.
Accuracy outweighed speed as the primary success factor. The top performers found a balance between steady ROP and precise well placement.
All of the top 10 players have In-Zone Percentages consistently above 85%. This highlights the importance of precision over sheer speed.
The fact that their average In-Zone Percentage is around 88% shows that the top competitors prioritize well-path accuracy.
Top performers adopt a balanced approach: maintaining a good ROP while keeping their In-Zone Percentage high.

Carnarvon Basin – Lower Barrow Group Reservoir
The Lower Barrow Group in the Carnarvon Basin is a high-quality conventional reservoir, characterized by thick, clean sands with high porosity (~30%). This target zone benefits from fault-based traps and effective seals, making it ideal for consistent hydrocarbon production.
High precision was crucial for success, with top players focusing on stability and accuracy, even at the cost of slightly reduced speed.
This near-perfect accuracy highlights that the best players focus heavily on keeping the bit in the target zone, ensuring precise well placement.
Prioritize Accuracy Over Speed- Focus on achieving and maintaining a high in-zone percentage, even if it means reducing ROP slightly.
Steady ROP Management- Keep ROP consistent rather than fluctuating aggressively, as a stable ROP seems to correlate with better accuracy.

The Geosteering World Cup will consist of a one-day event taking place on September 16th 2025 (Worldwide) from 10:30 – ~1:00 PM CDT. Please look below for other region times.
The Geosteering World Cup is a free event open to everyone to participate. Participants will be divided up by regions depending on their country of residence.
The cup will be hosted on ROGII’s Solo Cloud Platform using ROGII’s StarSteer Geosteering Software. At 10:30 AM CDT, the competition will go live for the following regions: North America and Latin America. Please see below for Europe & Middle East competition times. Competitors are encouraged to have logged into their accounts prior to the competition to identify any issues. Once the event begins competitors will have 2 hours to steer 2 wells, 1 conventional & 1 unconventional. The basins these wells are generated from will be announced prior to the event starting.
Absolutely, we designed this competition to be open to everyone. If you do not have StarSteer installed on your computer or an expired license we will provide you with a temporary license key to practice before the competition & participate in the event.
There are no differences between regions however the wells steered in the two different heats will be different as they are not happening simultaneously. Users from all regions can compete in either heat as is convenient for them. In the final all competitors will be competing with each other directly using the same data.
We will be using synthetic data for the competition generated from current public data. The basins which will be drilled in the competition will be announced prior to the event starting.
Participants will be scored on a combination of 2 factors: highest percentage drilled in the Target Zone and average ROP. Each participant will receive their composite score as well as the solution after each well is completed.
Participants will receive their individual composite score for each well, their overall placement in the round, & position within the competitor pool.
Tools used during the competition for the conventional well include, but aren't limited to, MWD & LWD data. The competition may include steering with additional LWD data besides gamma.
Unfortunately, due to the large number of registrants we cannot teach participants in an individual manner. We will provide resources to learn on your own & provide technical assistance via email up to a week before the competition. If you are interested in learning more about our software or geosteering make sure to keep an eye out for our future ROGII U Geosteering courses & webinars.
A project will be released 2 weeks before the competition using elements like those displayed in the Cup. Completion of this project is not mandatory to participate in the event. You will also have access to StarSim, our geosteering simulator, when you receive StarSteer access.
ROGII will host multiple briefings to ensure all participants have StarSteer installed & are ready for the competition.
Participants that have made it to the top ten will receive a notification by email on the day of the competition, September 17th.
No, the only scores that will be made available to the public via social media and our website are those of the World Champion & Regional Winners. After the competition has been completed, we will list the top 10 finishers in order of rank. However, you are free to publish your scores & share them publicly as you wish. If for some reason you wish to compete anonymously, please contact us directly and we can have that arranged.
