A key element of the training strategy of Saudi Aramco's Upstream Professional Development Center is to utilize simulated work environments and project-based learning that is customized to the actual job roles, workflows, tools and data that trainees will encounter on the job. This paper presents details of the design, development and implementation of a project-based training course that serves as the capstone learning event in a program designed to develop new university graduates into independently contributing production engineers. The course provides participants with an opportunity to integrate and practice job-critical skills learned during the four-year program, using real company data, workflows and tools to work through a realistic well surveillance and testing project. The outcome of the course is a plan to optimize and manage a field that includes free flowing wells, artificial lift wells and gas wells. The learned skills are reinforced by having the participants repeat the exercise for an area of their assigned fields upon leaving the course, culminating in a presentation to their local management on their findings and recommendations. Project-based training that reflects actual work environments results in high learner engagement, higher retention levels and improved job performance. The opportunity to immediately practice the learned skills upon returning to work ensures the adoption of learning and adds business value. This work provides a model of training that can be utilized in any technical environment to design, develop and deliver training that improves individual job performance and adds value to the business.
