Scale & Characteristics of Heterogeneity in Sandstone Reservoir- Miri Formation (Hospital Road Outcrop)

This project is about a study of sedimentological and certain petrophysical
properties of Miri Formation specifically at Miri Hospital Road Outcrop. The objective
of this study is to characterize and quantify the reservoir heterogeneities. The objective
can be achieved by identiiying and analyzing facies characteristics, certain petrophysical
properties (porosity & permeability), and certain grain characteristics (size distribution
& sorting). The outcrop thickness ranges between 9.8 to lim and it comprises of seven
(7) layers. Among all those layers, five (5) of them are sandstone layers while the other
two (2) are shale layers. The best sandstone reservoir lies in Facies F which has largest
layer thickness (1.84- 2.40 m), less permeability barriers and it has good grain sorting.
