Sitompul, N., Rudiyanto, A. Wirawan & Y. Zaim (1992)- Effects of sea level drops during Late Early Miocene
to the reservoirs in South Palembang sub Basin, South Sumatra, Indonesia. Proc. 21st Ann. Conv. Indon. Petrol.
Assoc. 1, p. 309-324.
(Late Early Miocene sea level drops form sequence boundaries in late N6 and late N7. SB in Late N6 in Lower
Talang Akar Fm, forming thick sand bodies which could be reservoirs. Late N7 sea level drop produced
secondary porosity for carbonate reservoirs)
Situmeang & P.R. Davies (1986)- A geochemical study of Asameras Block A Production Sharing Contract,
North Sumatra Basin. Proc. 15th Ann. Conv. Indon. Petrol. Assoc., p. 321-340.
(N Sumatra Block "A" with 11 commercial oil fields, which produced over 100 MBO, and one non-commercial
gas field at Alur Siwah. In E part of block kerogen characterized by abundant land-derived organic material,
while marine sapropelic organic matter increases to W, suggesting influx of land- derived organic matter from
eastern land mass in area of Malacca Straits. Oils from Keutapang and Seureula Fm reservoirs of six different
fields typically non-waxy, paraffinic, with 49.2° - 59°API gravities. Oils have common origin, probably fine
grained marine sediments of M-L Miocene Baong Fm)

Formation, Ramba A and B pools, South Sumatra, Indonesia. In: C.T. Siemers et al. (eds.) Carbonate rocks and
reservoirs of Indonesia: a core workshop. Indonesian Petrol. Assoc., p 8.1 - 8.10.
(Ramba Field produced 60 MBO oi1 1982-1992 from A and B pools, separated by paleochannel. Best reservoir
rocks coral-rich packstones- wackestones, with 16-18% porosity)

evidence from Simeulue. Proc. 16th Ann. Conv. Indon. Petrol. Assoc. 1, p. 57-63.
(Cenozoic history of Simeulue, NW of Nias, includes Oligo-Miocene erosional unconformity. Repeated tectonic
inversions may be related in part to transpression and transtension stresses generated by strike-slip motion
interacting with sinuosities in trench and Sumatran fault system)

Indonesia. Proc. 12th Sess. CCOP, p. 255-262.

Situmorang, B. & B. Yulihanto (1985)- The role of strike slip faulting in structural development of the North
Sumatra Basin. Proc. 14th Ann. Conv. Indon. Petrol. Assoc. 1, p. 21-38.
(N Sumatra Basin development controlled by strike slip faulting. Several major N-S trending strike slip faults
mainly with dextral movements formed in present back-arc region and arranged in en echelon pattern. Since
then and until M Miocene, basin characterized by normal faulting. This episode corresponds to change in
Indian Ocean spreading direction from N-S in E Paleogene to NE-SW. Convergence highly oblique in Late
Miocene, producing compressive deformation and uplift. Compressional structures continuously affected
sedimentary cover in Plio-Pleistocene due to strike slip faulting along Sumatran Fault system)

Sumatera. In: Geologi Indonesia: dinamika dan produknya, Geol. Res. Dev. Centre, Bandung, Spec. Publ. 33,1,
p. 29-48.
(Two prominent NW-SE transcurrent fault zones in Sumatra: Sumatera FZ parallel to the axis of the Barisan
Mountains and Mentawai FZ along E slope of fore-arc ridge. N of Nias, MFZ and SFZ are linked by Batee
Fault. Transtentional basins in back-arc (N, C, S Sumatra, Ombilin) and fore-arc (Singkel, Pini in NW, Bose,
Sipora grabens in Mentawai area and Pagarjati, Kedurang in Bengkulu to SE).
