Why should you attend?
Current complex numerical models analyse data, detect patterns of risk precursors, and propose appropriate course of curative actions to mitigate risk, to reduce NPT, to optimize costs, to properly assess the resource, and to enhance production. But on what bases? To get some critical hindsight on these outputs, attendees will be taught geomechanics from a multi-disciplinary approach, using dedicated methodologies.
Main Objectives:
Upon completion of the course, attendees will be able to:
- Understand the connection between depth key parameters and drilling NPT, inaccurate estimation of reservoir properties, hydraulic fracturing or fault re-activation.
- Understand the mandatory data and required workflows to build a 1D Geomechanical model from the well scale to the reservoir scale.
- Acquire the knowledge in Geomechanics to take part in petroleum and deep geothermal projects.
Learning Approach:
The constructivist approach has been chosen as the learning approach.
At first, attendees with be interviewed to take stock of the state of qualifications and experiences of the audience. Then, the course will be managed according to operational needs of use or specific business requirements.
This course will necessitate an active participation of attendees to share knowledge and experience, with hands-on practical exercises for knowledge assessment.
All documents are provided. However, the course requires personal portable computers with XLS software.
HSE requirements:
No specific requirement for this course that can take place in any meeting room equipped with computers and a screen with common HSE characteristics, in your company premises or elsewhere.
Course Agenda:
