Abstrak :
Reservoir batupasir pada Lapangan OA terletak pada Cekungan Northern Bonaparte merupakan batupasir yang tersaturasi gas, diagenesis mineral menyebabkan beberapa daerah zona reservoir menjadi tight sandstone. Metode inversi menggunakan impedansi akustik (AI) kurang sensitif dalam membedakan litologi batupasir dan batu lempung karena memiliki nilai impedansi yang hampir sama. Simultaneous Inversion mengatasi masalah tersebut dengan melakukan inversi secara bersamaan melalui data partial angle (near, mid, far) untuk mendapatkan parameter fisis selain impedansi akustik yang diharapkan lebih sensitif dalam membedakan litologi maupun memprediksi keberadaan fluida gas seperti impedansi shear (SI) dan densitas. Ketiga parameter tersebut dapat diturunkan menjadi parameter Lame(LMR). Analisa crossplot menunjukan parameter fisis yang sensitif untuk memprediksi persebaran litologi maupun keberadaan fluida gas. Parameter densitas cukup sensitif dalam membedakan litologi yang kemudian dilakukan inversi dengan nilai cut off clean sandstone adalah 2.3-2.5 (g/cc), tight sandstone dengan cutoff 2.5-2.625 (g/cc) dan shaledengan cutoff2.625-2.8(g/cc). Keberadaan fluida gas diprediksi dengan melakukan inversi parameter Vp/Vsyang memiliki cutoff ±1.6 dan Lambda-rho dengan cut off ±25. Analisa peta persebaran parameter tersebut menunjukan persebaran batupasir dan keberadaan fluida gas dominan berada di daerah utara zona penelitian dengan karakter batupasir yang relatif memiliki porositas yang lebih baik (clean sandstone) dibandingkan dengan daerah yang relatif lebih selatan.

The sandstone reservoir in the OA Field is located in the Northern Bonaparte Basin, which is gas-saturated sandstone, mineral diagenesis causing several reservoir zone areas to become tight sand. The inversion method using acoustic impedance (AI) is less sensitive in distinguishing sandstone and clay rock lithology because it has almost the same impedance value. Simultaneous Inversion overcomes this problem by simultaneously inversingpartial angle data (near, mid, far) to obtain physical parameters besides acoustic impedance which are expected to be more sensitive in distinguishing lithology and predicting the presence of gas fluids such as shear impedance (SI) and density. These three parameters can be derived as Lame(LMR) parameters. Crossplot analysis shows sensitive physical parameters to predict the distribution of lithology and the presence of gas fluid. Density sensitive in distinguishing lithology which is then inversed,obtaining clean sandstone cutoff values are 2.3-2.5 (g/cc), tight sandstonewith cutoff 2.5-2.625 (g/cc) and clay stones with cutoff2.625-2.8(g/cc). The presence of gas fluid is predicted by inversing the parameter Vp/Vswhich has a ± 1.6 and Lambda-rho cutoff of ± 25 cutoff. Analysis of the parameter distribution map shows the distribution of sandstones and the presence of dominant gas fluids in the northern area of the research zone with relatively clean sandstone characteristics, compared to relatively more southern regions.

Napoleon Bornaparte was great French Emperor. Based on the constitution of 22 Frimaire I'an VII (December 13, 1799) Napoleon Bornaparte took place the directory governance as first consul (Primier consul) together with combacerres as second consul and lebrun as third consul. As first consul, Napoleon Bonaparte had a special right that the others. He took role as chief of state. In this constitution, it was written that Bonaparte was pointed as first consul. It means that the constitution was made for him. Based on the amandement of the constitution in 1892, dated 16 thermidor 1 'An X I August 4 1802), the constitution mentioned Napoleon as the long life consul. This condition brought out many consequences, especially in all over French Metropolitan. Napoleon became a dictator. He had right to gover alon without consulting with other highest principal institution.After murder trial to Napoleon, Frech people send a petition to the parliament to change the form state into a Kingdom State. Therefore,based on the Constitution of 28 Floreal I'An XII (May 18,1804) the French state became a French Kingdom. Napoleon Bonaparte was pointed as French Emperor. He received full executive power. He arranged all the country as a modern state and built transnational roads connecting Paris with 25 other countries in Europe.Napoleon brought French Nation to be great country and the integrated many countries under his authority.
