Abstract
Research area is located at “X†block, part of South Sumatra basin,
South Sumatra Province.
Analysis performed within this research is sequence stratigraphy focused
at Upper Talang Akar Formation. The Analysis were aiming to know the sequence
stratigraphy and distribution of system tracts. This research can be applied to
understand the prospect zone .
Pursuant to the analysis result which are using seismic and well log data,
the area accurately consist of 3 sequence, that are sequence I which consist of the
highstand system tract I, sequence II which consist of the transgressive system
tract II and highstand system tract II, and also sequence III which consist of the
transgressive system tract III and highstand system tract III.
The sequence stratigraphy being held before is reference to divided the
prospect zone. The prospect zone above which is Zone A, Zone and Zone C.The
rock properties from each other zone have been calculated, which is porosity
(Ф), shale volume (Vsh), water saturation (Sw) etc. The results is important
parameter for hydrocarbon reserve calculation. The reserve calculated by
probability approach with monte carlo method.
The provenance of this deposits is interpretatively derived from eastsoutheast
ward, that is Lampung High.
Pursuant to the sequence stratigraphy analysis, some hydrocarbon
prospect areas all present at high stand system tract deposits.
