| Summary: | Tuna field, a giant gas field operated by Total which developed from the discovery well in 1977,
and until the month of March 2012 has been carried as many as 912 wells drilling wells,
consisting of 24 exploration wells, 24 wells deleniasi, and 864 development wells. Current daily
production of gas around 1340MMSCF and 27 200 bpd of condensate, with cumulative
production Tuna field for 20 years has reached 8.01 TCF of gas +177.5 MMbbls condensate, has
been developed with the concept of Grid.
The physical properties of rocks and 1D modeling conducted, showed that the delta plain area
where coal and organic mudstone deposited showed a high amplitude, as well as contrasting
limestone in pro-delta region shows a high amplitude contrast, but the water saturated
sandstones, and sandstones saturated gas, there is not much impedance contrast, the amplitude is
very small so that dimming.
The results of the environmental interpretation of deposition of 6h (U9.5) phase interpreted to be
the 'late highstand', which was then in line with falling sea levels, delta prograded to eastward
until it reaches the phase of 'Lowstand' on 6e/6d layer, then sea level rise and delta comes to
Trangression phase, it retrograded to the west up to the age of 5a. |
