However, with extremely keen competition for jobs in recent years, an increasing proportion of entrants to this occupation have previous work experience as a roustabout or a 2-year degree in petroleum technology providing knowledge of oil field operations and familiarity with computers and other automated equipment. Applicants must be physically fit and able to pass a physical examination. Employers seek candidates who have mechanical ability, agility, coordination, and good eyesight. Companies may administer aptitude tests to prospective employees or screen them for drug abuse. Roustabouts usually are hired in the field by the maintenance superintendent or by a local company representative.
Companies generally hire workers who live near the work site.
Employers are often reluctant to invest in training because of the relatively high turnover rate among roustabouts. However, some employees are given an opportunity to take courses offered by various junior colleges. In some companies, roustabouts participate in educational assistance programs that pay for job-related courses taken on the employee's own time. Roustabouts start by performing basic laborer tasks such as unloading trucks and digging trenches. As they gain experience, they progress to more complex tasks such as fixing motors or repairing pumps.
