SURFACE CHARACTERISTICS OF SELECTED SHALES FROM SETAP FORMATION, SARAWAK, MALAYSIA

The exploration and exploitation of oil/gas resources to meet the drastic energy
demands in the world has necessitated an enhanced understanding of the surface
chemistry oforganic rich shale formations. An investigation was thus been conducted
to evaluate variations in the surface characteristics of selected samples from shale gas
potential Formations in the Sarawak basin, Malaysia. The impact ofsuch variations on
the surface potential of the shales were also elucidated. Results of experimental data
analyses indicated that specific surface areas have complex interrelationship with the
type and content oforganic matter, mineralogy and affect surface characteristics inthe
Setap Formation. Mineralogical study delineated two main sets clay mineralization.
