Weak Signals Video and Scripts
The Weak Signals video is intended to be used during a rig-based safety meeting for personnel involved in managing Wells Process Safety. It is intended to be used to facilitate discussions, relevant to both the individuals, the team and the rig.
The video has 6 different scenes and includes voices of key individuals involved with controlling process safety. After each scene there are some questions which can be discussed by the audience, so the instructor can stop the video after each scene to facilitate the discussion. The facilitators guide is available to download here.
It is suggested that drilling contractors, service providers and operator personnel use this resource. Group size is expected to be around 10-12 people, but you may want to break into smaller groups for the discussion.
The video last 17 minutes without discussion. The total time of the exercise including the video and discussion is approximately 1 hour.
Level 1 Well Control Awareness Course
The IWCF Level 1 well control awareness course aims to increase candidates understanding of how well control incidents can occur, their consequences and prevention methods.
Level 1 is the industry’s first free, online course which is perfect for anyone new or experienced in the industry, especially students and graduates, personnel involved in well control and those who are simply interested in well control.
The Level 1 course has 7 modules which cover the following topics:
- Overview of Oil and Gas
- Life Cycle of a Well
- Drilling Rigs
- Well Control During Drilling Operations
- Well Intervention and Workover
- Pressure Control During Well Intervention
- Conclusion.
You can find out more about Level 1 by viewing the course video or you can register below.
Well Operations Crew Resource Management Awareness Course
In addition to our free Level 1 course, we recently introduced a free, online Well Operations Crew Resource Management (WOCRM) awareness course focusing on non-technical skills.
There are 6 modules which candidates can complete with a knowledge check after each module. Once candidates have successfully completed all 6 modules, they will sit a final assessment. If a pass mark of 70% or more is achieved, they will receive an instant certificate.
The 6 course modules include:
- Situational Awareness
- Decision Making
- Leadership
- Communication
- Teamwork
- Performance Factors
