Below are some examples of matrices for the upstream oil and gas industry. These provide a general idea of what some companies are using but you will need to contact your customer directly to find out specifically what they require. The Health, Safety, Environmental training, listed for each service category, may not meet all of your training needs. Each contractor company determines their own HSE training needs for the services they provide. These training needs are based on federal, state, and local laws along with any contractual agreements that have been made. As examples, the matrices are placed here only to let you know what operators mean when they ask if a contractor has a HSE training matrix.
