For the second half of the year Interra will drill three development wells and undertake 3D seismic data work in Indonesia, while two development wells are to be drilled in Burma.
It will also interpret new 2D seismic data prior to drilling an exploration well in Thailand.
Interra said it will take care not to become too exposed by any one investment and is seeking to further geographically diversify its portfolio.
"Of course, oil and gas is an inherently risky business, but much can be done to reduce those risks," Interra chief executive Luke Targett said.
"To enhance our portfolio, we are looking for opportunities in Australia not just in the oil and gas sector but right across the energy spectrum."
Interra, which is also listed in Singapore, owns a 70% non-operating interest in the producing Tanjung Miring Timur oil field onshore Sumatra, Indonesia; 60% of both the Chauk and Yenangyaung onshore oil fields in Burma; and a 50% stake in the L3/48, L9/48 and L17/48 exploration blocks onshore Thailand.
Tanjung Miring Timur is about 120km southwest of Palembang and produced 275,697 barrels of oil in 2007, while the Chauk and Yenangyaung fields produced 731,410bbl.
