| dc.description | Metode EEI merupakan perluasan dari Accoustic Impedance (AI) dan Elastic Impedance (EI) yang diperkenalkan oleh Whitcombe, D.N., Connolly, P., dan Reagan, R.L., (2002). Metode ini bekerja dengan memanfaatkan gelombang datang non-zero untuk melakukan pendekatan parameter elastik tertentu pada sudut konstan seismik. Impedansi EEI mampu merepresentasikan kurva parameter elastik di sudut chi tertentu. Dalam penelitian ini metode EEI diaplikasikan untuk mengetahui prediksi pola persebaran hidrokarbon gas pada lapisan reservoir tipis di Lapangan Penobscot, Nova Scotia, Kanada. | en_US |
| dc.description.abstract | Penobscot Field is an exploration field located in Scotia Basin, Nova Scotia, Canada. Based on Canada-Nova Scotia Offshore Petroleum Board (CNSOPB) in 2008, Penobscot field has an indications of hydrocarbons presence in the form of gas. There are two wells available, Penobscot L-30 (gas well) and B-41 (dry well). In this research, prediction of gas distribution in Sand 4 layer within Missisauga Formation was obtained by applying Extended Elastic Impedance (EEI) inversion method. The results from cross-plot analysis shows that sensitive parameters for separating fluid types are Lambda Rho and Vp/Vs parameters. The next step is to perform a cross correlation between Lambda Rho and Vp/Vs parameters against EEI log to obtain the optimum 𝜒 value. Lambda Rho log response has a correlation value of 0.97 with EEI at 𝜒 = 18°, while the log Vp/Vs response has a correlation value of 0.99 with EEI at 𝜒 = 31°. Gas can be distinguished by an EEI 18° at an elastic impedance less than 27000 (ft/s*g/cc) and an EEI 31° less than 26000 (ft/s*g/cc). The results of the EEI inversion indicates that the hydrocarbon of gas content spreads along ± 4 Km to the southwest and ± 2 Km to the north from the L-30 well. | en_US |
