Abstract Seismic attribute analysis has been done in Penobscot Field, Scotian Basin. This analysis was done to

conclude a new area for well drilling on Missisauga formation in the field. The formation was chosen

based on initial well data that show a promising area on sandstone reservoir in Missisauga formation.

The analysis is focused on two horizons that we called Top Sand 3 and Top Sand 5. We analyse the

RMS amplitude and instantaneous frequency attributes to characterized reservoir on both horizons.

From the integration of both attributes, we can proposed a new well drilling points which in this case,

the points are located on southwest of the field.

Keywords: Instantaneous Frequency, RMS Amplitude, Seismic Attribute.

Abstrak

Analisa atribut seismik telah dilakukan pada Lapangan Penobscot, Cekungan Scotian. Analisa ini

dilakukan untuk menentukan sebuah area baru untuk pengeboran sumur pada formasi Missisauga di

lapangan. Formasi ini dipilih berdasarkan data dari initial well yang menunjukkan area menjanjikan

pada reservoar batupasir pada formasi Missisauga. Analisa difokuskan pada dua horison yang disebut

Top Sand 3 dan Top Sand 5. Kemudian dilakukan analisa atribut amplitudo RMS dan frekuensi sesaat

untuk karakterisasi reservoar pada kedua horison tersebut. Dari integrasi kedua atribut tersebut, dapat

diusulkan sebuah titik-titik pengeboran sumur baru dimana dalam kasus ini, titik pengeboran sumur

baru terletak pada arah barat daya lapangan.

Kata Kunci: Atribut Seismik, Amplitudo RMS, Frekuensi Sesaat

Introduction

In the recent years, the rapid human

population is increasing. It means, the

energy demand is increasing as well. One

of the biggest energies that human needs is

an energy that derived from hydrocarbons.

One of the hydrocarbons potential can be

found in Penobscot Field, Scotian Basin.

In 1976, PetroCanada-Shell was drilled an

initial well, Penobscot L-30, with the total

depth 4237.5 m in 138 m from water

surface. Unfortunately, it was dry hole with

oil & gas show. Even though the well was

dry, the exploration result show a

promising area on sandstone reservoir in

Missisauga formation.

From that sole statement, the purpose from

this study is to conclude a new area for well

drilling on Missisauga formation in

Penobscot Field, Scotian Basin using

seismic attribute through the seismic data

RMS, (d) Top Sand 5 Frequencies, that overlay with contours of the depth structure map.

Conclusions

From well data information, it is known that

wells B-41 and L-30 are dry holes. The

information is suitable with the data

obtained from the RMS attribute and

instantaneous frequency, both wells are

located in the areas with low amplitude and

high frequency.

In the Penobscot field, the area that can be

proposed as a new well drilling point is

around one of the faults (red circle in figure

7). Because from the RMS amplitude

attribute analysis, the area has a high

amplitude value. Then when integrated it

into the instantaneous frequency attribute,

the area has a low frequency value. High

amplitude and low frequency values in a

seismic cross section is a DHI which can

detect hydrocarbons in that area directly.
