| Summary: | Underground coal gasification is one of the insitu coal conversion technologies into synthetic gas
(syngas) which is potential to displace petroleum and natural gas in the future. UCG technology was
referred to as clean energy technologies, because the gas extraction process was conducted through insitu burn coal without excavation of overburden rock and coal seams in advance as is commonly done in
conventional mining system. But in order for UCG can be accomplished, there are several requirements
that must be met, which in the area that will do partial combustion should not be saturated with fluid (in
this case is a layer on top of the coal). Because of the conditions that must be met above, resistivity
method with Wenner configuration is the most appropriate method to analyze water saturated zone in the
area of research. The existence of the fluid that fills the pores between the rocks under the surface can be
determined based on the resistivity value character. From processing data using EarthImager can seen
beneath the surface wherein fluid saturation zone on each track has an average resistivity values ranging
from 3-18 Ωm with lithology in the form of alternating between sandstones and limestones from
muaraenim formation (middle Palembang formation) which has age of Middle Miocene to end of
Pliocene. To further strengthen the interpretation, resistivity data that has been processed is also
correlated with coring every existing wells. |
