The primary qualifications for getting a job in oilfield sales are a high school diploma and several years of experience in a sales position, preferably with a travel component. Some employers prefer applicants who have a bachelor's degree in business, engineering, or a related field, though many also accept equivalent work experience in place of formal education. Companies value experience in this area, so the more time you spend in sales, the easier it is to get this position. Fulfilling the responsibilities and duties of an oilfield sales job requires sales skills, interpersonal skills, reliable personal transportation, and a personal understanding of what oil and gas companies are most interested in buying for each site.
