Abstract Over the past few years, security has become increasingly important to companies operating in the worldwide oil and gas industry. Unlike traditional management functions such as finance, marketing, or personnel, security management is a domain for which competencies are not developed internally. Line management and employees may not be familiar by new security requirements such as physical security measures, armed convoys, living and working behind military protection, and security risk assessments. In today's world, the energy industry requires definitive security support to deliver its commitments. Corporate management teams that engage best-in-class security advisors and adopt their recommendations will build confidence in their organizations. External security consultants must supply competent staff that is capable of adapting to the organizational cultures of their clients while providing consistent assessments and recommendations. Local security authorities have no option but to evolve and deal with an often elusive threat. It is vitally important that security management be integrated into stakeholder cultures, which will require a mindset change. An evolution of this magnitude can only be enforced with a top-to-bottom drive. However, the key to success is to convince and train middle management, empowering them to carry the banner. The process takes time and a visible commitment from upper management. This paper will detail how a major oilfield service company is managing this mindset change.
