Description:
|
This three-day course is designed for a single customer attending Drillworks Standard training. This package of training includes theory overview and focuses on the foundational Drillworks applications: Predict, 3D, and ConnectML. The techniques discussed will be focused on practical versus theoretical techniques that will allow students to evaluate the credibility of the modeled results and consider them appropriately in the well construction decision-making process. This course reinforces the geopressure concepts presented and provides hands-on training in pore pressure analysis using Drillworks Predict and Drillworks 3D modules. Students will learn how to build and calibrate 1D and 3D petrophysical geopressure analysis using log, drilling and seismic data.
