Jan 2008 – Present:

Coordinator and Instructor of ADNOC CAMS (Competency Assurance Management System) - OBC (Onboarding Course)

This OBC course will link the newly graduates’ CAMS development programs to the real work done in the E&P companies. It provides the participants the learning opportunity to develop lifelong, transferable skills and values. It can serve as a catalyst for change in the E&P Group of Companies. It is designed as a survey course that will give participants the business, HSE and interpersonal skills needed by the participants to more effectively, add value to the work their teams do, and in turn their respective companies.

Throughout the 4 weeks of the OBC there will be several case studies linking the various elements of E&P together as a red thread to get the participants to see the interactions and how things link to each other rather than acting as separate elements.

Using state-of-the-art learning and development techniques, the program covers the full life-cycle of the field development process. In doing so, it presents, in context, current and emerging technology, and emphasizes that managing uncertainty is critical to the E&P business, both oil and gas.

The program should raise a number of questions which the participants have to find the answers to by searching for the solutions, consulting with the lecturers etc. the OBC contain 80% learning from working on case studies and real data and 20% from lecturing.  The case studies will be based on local data, and be relevant in the context of the E&P companies.

That means that most of the learning activities will happen in syndicates or small workgroups. As it represents the life cycle of a field, it is important to manage the design of the various elements in an integrated approach and not as a number of short courses put together.
