A novel concept, local content, in oil industry is gradually emerging. Local content should be defined in terms of value addition in local country (by local staff, local materials, local services and facilities) rather than in terms of ownership of the company performing the value added activities. Many oil exporting countries have taken a positive approach toward local content development to maximize the benefits from oil and gas extraction. The purpose of this study is to develop a conceptual model for local content development in petroleum industry. Local content can generally be defined in terms of the ownership and/ or location of the enterprises involved in production and/ or the value-added in the production process. Local content promotion will have to vary significantly between countries, depending on the current status of their economic, political and social development. This model is useful for state governments to consider all aspects and factors affecting local content development generally. Local content development outcomes are economic growth, industrial growth and spillover effects. The paper begins with examining the factors accommodated in literature believed to influence the local content promotion. Based on our review, the conceptual model derived includes key factors of local content that evaluate local content development, and examine interrelations between local policies, local infrastructure, local environment, and local capability.
