Thailand's national oil and gas company PTT, through its Exploration and Production branch PTTEP, plans to invest US$24bn over the 2015-2019 period, of which 80% will be directed to investments in Thailand and Southeast Asia. The company expects to have reached a sales volume of 320,000 boe/d in 2014 (+9% over 2013) and to increase sales by 6% in 2015 to 343,000 boe/d. The increase in sales in 2014 is linked to the start-up of the Zawtika project and the acquisition of Hess Thailand. The majority of the company’s production is natural gas, accounting for 67% of total sales volumes. In 2015, the group aims to invest US$4,832m, of which 52% will be allocated to maintaining production levels for projects in Thailand, namely the Arthit Project, S1 Project, Bongkot Project, Contract 4 Project, and MTJDA-B17 Project. The remaining 20% will be directed at projects in Southeast Asia, mainly in Myanmar, to maintain production levels for Zawtika Project, development of Myanmar m3 Project, and potential study for Myanmar PSC G & EP 2 Project, Myanmar MOGE 3 Project, Myanmar MD-7 and MD-8 Project.
