Abstract

Sillimanite is a brittle mineral as a metamorphic mineral product which is
generally derived from clay, along with an increase in pressure and high
temperature (600˚C - 900˚C), and kaliophilite is also a brittle mineral as a
potassium bearing in the sand-shale series, which contributes to the clay
diagenesis process. In the development of shale hydrocarbon in the
Brownshale formation in the Bengkalis Trough, Central Sumatra Basin, using
the correlation of the XRD (bulk and clay oriented), TOC, Ro, and MBT
analysis results from the drill cuttings of well BS-03, so that the fracable zone
interval can be determined. From this correlation, it shows that the presence
of sillimanite and kaliophilite minerals as minor minerals greatly affects the
changes in shale character and hydrocarbon generation, where at depth
intervals of 10,780 ft downward (sand series-shale) there is an interesting
phenomenon, i.e. low MBT, low TOC, and high Ro, so it is believed that the
depth interval of 10,780 ft downward is a fracable zone interval (brittle shale)
which is a good candidate for hydraulic fracking planning, while the upper
depth interval is a fracture barrier.
