Telah dilakukan karakterisasi reservoar hidrokarbon pada Lapangan Penobscot Kanada menggunakan atribut energi dan metode Seismic Coloured Inversion (SCI) di sepanjang inline 1284 m. Penelitian ini menggunakan data seismik post stack sebagai data input dan data sumur sebagai data kontrol untuk menentukan nilai impedansi akustik (AI). Analisis sensitivitas log yang digunakan menunjukkan bahwa gamma ray log lebih sensitif dalam pemisahan lapisan sand dan shale. Analisis atribut energi dilakukan untuk meningkatkan resolusi vertikal dari penampang seismik untuk menentukan zone of interest. Analisis inversi SCI dilakukan untuk melihat pola sebaran nilai AI pada penampang seismik yang diteliti. Dari hasil inversi SCI terhadap penampang seismik diperoleh nilai AI antara 2,00 x 106 kg/m2s sampai 5,56 x 106 kg/m2s. Hal ini menunjukkan bahwa pada penampang seismik yang diteliti terdapat potensi reservoar hidrokarbon.
