Enable discipline experts to work together and make the best possible decisions—from exploration to production.
Shell U.K. Limited’s G&G team and reservoir engineers were routinely using the Petrel workflow for drilling, but the drilling engineers were not.
Schlumberger proposed implementing a single multidiscipline solution to be used by all. The power of Petrel seismic-to-simulation software enables collaboration by all parties—including geologists, geophysicists, drillers, reservoir engineers, and production engineers—in the same shared earth model. Schlumberger demonstrated that the solution would be very useful for the drilling engineers and that including them in the unified workflow would benefit the entire team.
Using a single workflow process powered by Petrel software improves the planning workflow as well as optimizing well placement and drilling operations.
Shell U.K. Limited articulated its requirements, which included the following points:
To test implementing the process for all its disciplines, Shell U.K. Limited carried out a project to generate 3D models for various individual drilling parameters, extract synthetic logs, and determine the optimal drilling window. The project created 3D models for unconfined compressive strength, weight on bit, rate of penetration, drilling rate, time to drill, and drilling events.
The Shell U.K. Limited subsurface team and Schlumberger Information Solutions carried out the project, collaborating with personnel from Schlumberger Drilling & Measurements, Geoservices, and Smith Bits.
The project was accomplished in 11 days, delivering great added value in a short time. The Petrel drilling workflow helped the drilling team to work in a proactive mode and better anticipate problems that could lead to nonproductive time or less-than-optimal reservoir contact. It also enhanced collaboration between disciplines, including the drilling engineering staff, because it provided a common collaboration platform for the subsurface team. The platform offers
During the execution phase, real-time data was superimposed on the modeled data, which showed very good agreement, indicating that models were quite predictive of the actual reservoir drilling conditions.

Challenge: Fully integrate workflow so that the drilling and G&G teams can access all information to collaborate and better anticipate drilling issues.
Solution: Use Petrel drilling workflow to gather knowledge and lessons learned to perform well planning and optimization tasks. The following modules were used.
Results: Fully integrated valuable information from various areas of expertise, ultimately reducing risk and improving drilling performance.
