Exploration costs in South Sumatra are expected to be low with estimated well and seismic costs likely to be about US$1.2 million
and US$2 million (for 500 kilometres of 2D seismic) respectively

Is this even relevant now?

Article also says this:
The Ranau PSC is a 30 year contract with an initial 6 year exploration period

We don't even have money for 6 years exploration at the burn rate

I don't know if the current seismic was 2D or 3D, going to keep looking
