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. Introduction PT. Caltex Pacific Indonesia, commonly known as CPI or Caltex, is a production-sharing contractor to BP-Migas, Indonesia's national energy company. Caltex is Indonesia's largest oil producer, producing over 500,000 barrels of crude oil per day from 82 fields within 3 contract blocks. The distances between CPI's producing fields and operational bases range up to 150 km. Figure 1 depicts the general location and geographic range of CPI's operations. CPI has produced oil from within Riau Province, Sumatra since 1952. Riau province is an equatorial lowland area comprised primarily of palm oil plantations, swampy areas and secondary rainforest. Commercial enterprises and municipal infrastructure have been historically limited in the area, necessitating self-sufficiency in CPI in terms of housing, schools, hospitals, electricity, roads, pipelines, telecommunication, heavy equipment and vehicles. CPI employs approximately 6,500 people and contracts an additional 25,000 to produce oil and provide these services. Collectively these industrial, residential, institutional, construction, and municipal activities generate several types of waste. Waste Management Program CPI's goal is to be recognized by industry and the community in which we operate as a leader in health, environment, safety, reliability and efficiency. In accordance with this intent, CPI covened a team to critically review current waste management methods to ensure regulatory compliance and technical adequacy. Upgraded waste management techniques were identified as an important strategy to minimize operating costs by preventing the creation of remediation liabilities. A structured five-phase project management process was employed to ensure stakeholder alignment, decision quality, and efficient execution:Identify the gaps between the current and desired state;Define the optimal solution that closes the gaps;Refine the selected alternative and develop an implementation plan;Implement the selected alternative socialize the new procedures. Phase 1 - Define the problem Phase 1 was initiated by collecting the data necessary to assess the adequacy of the prevailing waste management practices and facilities. Inventories of generated wastes and waste management facilities were prepared, and the methods currently used by individual groups to manage each waste type were documented. The current waste management practices were critically assessed to identify procedural or technology gaps. Easily rectified gaps were closed as a priority.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
