the 10 existing wells

I believe these are the 10 wells we are trying to jointly develop. ;)

Exploratory drillings in the area took place
between Mt. Sibayak and Mt. Pratektekan.
Pertamina drilled 10 wells in the Sibayak
field from 1991 to 1997, comprising 7
production wells (SBY-1, SBY-3, SBY-4,
SBY-5, SBY-6, SBY-7 and SBY-8) and 3
reinjection wells (SBY-2, SBY-9 and
SBY-10). The reservoir temperature
ranges between 240 and 300°C, and
pressure varies between 45 and 110 bar-g.
Most of the wells are non artesian with
pressure at the wellhead in shut-off
conditions. The enthalpy of the reservoir
reaches 1100 kJ/kg and the maximum
wellhead pressure is 21 bar-g in flowing
conditions. Steamflow from the
production well achieves 51.4 kg/s at 9 bar
pressure

At present in the Sibayak geothermal field,
a 2 MWe mono-block turbine is installed
to produce electricity with steam supplied
from well SBY-5. Pertamina is committed to expand the capacity by replacing the 2 MWe monoblock
turbine with a 10 MWe condensing turbine. This paper will briefly describe how the electrical
power generation can be maximized in the Sibayak geothermal field by using wells SBY-3, SBY-4,
SBY-5, SBY-6 and SBY-8 as production wells to supply steam to the power plant.
