Abstract

The Lakat Formation of Central Sumatra field
is a mature field that has been produced since 1970,
and in 2018 the recovery factor has reach of 25.9%. In
order to increase the recovery factor, hence the infill
well scenario will be executed. Determination of the
location of infill wells was carried out using the Decline
Curve Analysis (DCA) Sectorization Method, due to in
this field there is no SCAL and PVT data. The DCA
sectorization method uses statistical analysis based on
HCPV and permeability value. Determination of the infill
wells coordinate is based on an overlay map of the
three HCPV sectors, are current, permeability, and
cumulative production. This method divided the
formation into good, medium, and poor classes. The
infill well scenario is done in good and medium classes.
The initial production rate of each infill well is
determined by drawing a trendline on a combination of
peak production, pressure, transmissibility, productivity
index and time. The results of the analysis in the Lakat
formation obtained in the good sector the exponential
curve with decline rate of 7.3% has remaining reserve
about 56 Mbbl. Whereas the medium sector by
harmonic curve with decline rate 9.4% has remaining
reserve about 71 Mbbl. The development of Lakat
formation with 8 infill wells, including 6 locations in the
good sector with an average initial production rate of 68
bbl/day, and 2 locations in the medium sector with an
average initial production rate of 59 bbl/day. Based on
the development scenario results in the Lakat layer of
the Central Sumatra Field has obtained of oil production
of 6479 MSTB and recovery factor of 36.1%.
