Abstract

Abstract As a production-sharing contractor to BP-Migas, PT Caltex Pacific Indonesia (CPI) is Indonesia's largest oil producer. CPI employs approximately 6,500 people and contracts an additional 25,000 people in its operating area throughout Riau Province on the island of Sumatra. The distances between CPI's producing fields, limited waste management infrastructure, and the evolving nature of Indonesia's waste management regulations complicate waste management efforts. CPI's activities generate both domestic waste as well as conventional E&P waste. E&P waste management initiatives often focus exclusively on treatment and disposal. The 5R strategies of source reduction, re-use, recycle, recover and replace offer greater potential environmental and financial benefits for many common E&P wastes. As part of CPI's integrated waste management initiative, practical 5R strategies have been identified for several waste streams: seismic shot, excess cement, empty drums and containers, construction and demolition material, oil-based drilling mud, batteries, consumable IT products, used tires, paper, cardboard, and used oil. Development of these strategies is underway. Eventual implementation will minimize waste management costs and benefit the environment.
