The most populated country in Southeast Asia, Indonesia became a net importer of oil in 2004 and is estimated to contain more than 4 billion barrels of proven oil reserves, as of 2007. Indonesia's oil sector is controlled by several international oil companies, including supermajor Chevron, which pumps from the countries two largest oil fields, Minas and Duri, along Sumatra's coastline. However, the Southeast Asian country's largest producing oil fields are declining in output as they mature, and the Indonesian government is increasing efforts to curtail shortages in energy supplies, while spurring investments in the upstream sector.
Design engineers focus on applying the engineering design process, whereby they develop new or improved products or processes. They are required for projects that are onshore and offshore, upstream and downstream, and can specialize in multiple engineering disciplines including electrical, chemical, mechanical, civil and structural. Design engineers typically complete technical plans using computer-aided design (CAD) software, conduct testing by collecting and analyzing data, and complete regular progress reports for project managers.
