Siliciclastic sedimentary rocks are the most abundant of the sedimentary rock. They are formed from the detritus left over from the weathering of igneous, metamorphic, and older sedimentary rocks.<ref>Klein, C., and A.R.

====Lacustrine Reservoir====

This type of reservoir formed in basin containing water surrounded by land and initially formed by tectonic processes, volcanic, rifting, soil movement, the erosion by the wind on the coast or in land. The texture of sedimentary rocks in the environments usually granules grained and the size between  2 mm – 4 mm.
