The increasingly rapid development of the disciplines of petroleum engineering and petroleum geology has led to new methodologies and interpretation techniques forming new knowledge that should be offered quickly and efficiently to modem engineers and geologists.This need is equally important for students as well as for young professionals.Access and training to all scientific information is necessary to ensure success in their future careers.Today,e-learning has become a common medium for the management and distribution of on-line educational content.Learning Management Systems (LMSs) were not only developed to handle a large variety of multimedia content that provides an organized knowledge repository used to accelerate access to information and skill acquisition; but,LMSs can also keep detailed statistics on the use of the available material offering a powerful training and educational tool.In this document,the Petroleum Knowledge Tutorial System,an LMS platform offering a variety of online educational and training options to petroleum engineers and geologists,is presented.It was created using Moodle,opensource software that can be used to create on-line courses.The platform covers fundamental educational concepts in a structured way.It follows an optimized "workflow" that can be applied not only to solve a specific exercise but also any similar problem encountered over the course of ones career.The platform was designed to offer a repository of learning material in various forms and to favor user-platform interactions.It can be used for training and evaluation purposes through exercises and problem solving that the user can perform online by using browsing software along with internet access.Special tools were created and implemented on the platform to assist the user in completing a variety of tasks including performing exercises involving calculations with given data and plots of points or lines on graphs without leaving the learning environment.Furthermore,videos with detailed explanations follow each learning module and provide the full solution to every exercise.The LMS automatically keeps a large statistical database including the users access to activities on the platform that can be exported and further processed to improve the platform functionality and evaluate the usersperformance.
