Abstract The objective of this study is to perform forward stratigraphic modeling on the Kuwait Formation (also known as Kuwait Group) exposed stratigraphic succession along the Jal Az-Zor escarpment to explain the enigmatic occurrence of an elongated NW-SE geobody mapped from subsurface data at northern Kuwait. Outcrop measurements such as; stratigraphic successions, facies distribution, critical facies trends, and paleocurrent analysis have been collected along the 60 km length of the Jal Az-Zor escarpment. Such measurements were combined with thin section lab analysis to reveal the various sedimentary processes such as wave activity, grain size distribution, sediment supply sources, accommodation space, and erosional rates. These measurements were combined with subsurface data such as seismic attributes to reconstruct the paleography of the area and run a forward stratigraphic model simulation. The vertical succession was also utilized to reconstruct the relative sea-level fluctuation through time to develop an accurate model. Forward stratigraphic modeling resulted in building a robust and reliable facies distribution 3D model for the Jal Az-Zor escarpment that demonstrates the complex facies architecture. The model shows the various stacking patterns of several depositional sequences that are observed in the field as well as the subsurface. The enigmatic geobody mapped from seismic as a channel system in previous publications turned out to be a paleoshoreline. This shoreline is composed of high-quality sands as a result of an elevated level of wave activity. Reworking of barrier island sands was also found to be responsible for the enhanced reservoir quality. Consequently, regardless of the subsurface structure, the main driver of successful hydrocarbon accumulation is directly linked to the NW-SE trending paleoshoreline. To the best of the authors’ knowledge, this is the first time forward-stratigraphic modeling is performed along the Jal Az-Zor escarpment in north Kuwait and using such an approach to unravel Kuwait Formation heavy hydrocarbon subsurface occurrences.

Indonesian reformation era begins with the fall of President Suharto. Political transition and democratic transition impact in the religious life. Therefore, understandably, when the politic transition is not yet fully reflects the idealized conditions. In addition to the old paradigm that is still attached to the brain of policy makers, various policies to mirror the complexity of stuttering ruler to answer the challenges of religious life. This challenge cannot be separated from the hegemonic legacy of the past, including the politicization of SARA. Hegemony that took place during the New Order period, adversely affected the subsequent transition period. It seems among other things, with airings various conflicts nuances SARA previously muted, forced repressive. SARA issues arise as a result of the narrowing of the accommodation space of the nation state during the New Order regime. The New Order regime has reduced the definition of nation-states is only part of a group of people loyal to the government to deny the diversity of socio-cultural reality in it. To handle the inheritance, every regime in the reform era responds with a pattern and a different approach. It must be realized, that the post-reform era, Indonesia has had four changes of government. The leaders of every regime in the reform era have a different background and thus also have a vision that is different in treating the problem of racial intolerance, particularly against religious aspect. This treatment causes the accomplishment difference each different regimes of dealing with the diversity of race, religion and class that has become the hallmark of Indonesian society.

Seabed Sediments

Backscattered sound waves of seabed sediments are important information carriers in seafloor detection and acoustic characteristic parameters inversion. Most of the existing methods for estimating geoacoustic parameters are based on multiangle seabed backscattered signal processing and suitable for flat seafloor conditions with uniform sediment thickness. This usually deviates from the real field conditions and affects the accuracy of parameter estimation. In this paper, the sound ray propagation theory is studied and analysed under the condition of sloping seabed and uneven sediment thickness. Based on the phased parameter array sonar system, a method of acoustic parameters estimation of the sediment under inclined seabed conditions is proposed. The simulation results show that the new method shows good adaptability to different inclination angles of the seabed and solves the problem of accuracy of acoustic parameter estimation of the inclined seabed sediments. The model will greatly reduce the seafloor topography requirements in the sediment acoustic parameter inversion, such as velocity, layer thickness, and acoustic impedance.
