PT Chevron Pacific Indonesia (CPI) operates two major fields in Sumatra, Duri and Minas. Additionally CPI manages Dumai Wharf, the final terminal for oil transport.
The majority of CPI's Sumatran production in 2015 came from fields in the Rokan PSC. Duri, the largest field, has been using steamflooding technology to improve production since 1985 and is one of the world's largest steamflood developments. In 2015, steam injection was deployed in 77 percent of the field.
We continued to implement projects designed to sustain production, increase recovery and improve reliability from existing reservoirs. The Duri Field Area 13 steamflood expansion was completed in 2015 with all wells on production and injection by year-end.
We continued to optimize the waterflood program in the Minas Field. In 2015, work continued on a pilot project that uses a chemical injection process to further improve the recovery of light oil in the Minas and surrounding fields.
