2012PRAKTIKUM KE-IANALISA SIFAT PETROFISIK DAN FLUIDAA. Teori Dasar

Data sifat-sifat petrofisik dan fluida merupakan parameter yang sangat penting guna mengetahui kondisi bawah permukaan suatu sumur atau reservoir, karena dapat digunakan untuk menentukan besarnya cadangan hidrokarbon yang terkandung secara volumetric. Data ini antara lain adalah porositas, saturasi dan ketebalan lapisan hidrokarbon.

Satu dari cara untuk menentukan nilai-nilai parameter tersebut diatas adalah melalui hasil pengolahan data logging gamma ray log, resistivity log, density log dan neutron log. Hasil-hasil dari pengolahan data logging ini adalah berupa volume shale (Vsh), porositas () dan saturasi air (Sw).

Untuk mengetahui besarnya nilai-nilai porositas batuan rata-rata, saturasi air rata-rata, ketebalan hidrokarbon (lapisan produktip) dan letak kedalaman lapisannya adalah dengan cara menggunakan metoda cut-off dengan cara menentukan nilai rata-ratanya berikut ini :

EMBED Equation.3

N = jumlah data

Lapisan produktip yang merupakan zona hidrokarbon ditentukan apabila ketiga dari kriteria syarat cut-off tersebut diatas dipenuhi. Sebaliknya apabila salah satu dari ketiga syarat tersebut tidak terpenuhi dinyatakan bahwa jenis fluidanya air.

Selanjutnya untuk menentukan nilai-nilai porositas dan saturasi air adalah dengan cara menggunakan persamaan :

Sw = saturasi air

h = ketebalan lapisan produktip

B. Tujuan Praktikum 1. Menentukaan nilai-nilai cut-off porositas, saturasi air dan volume shale yang merupakan syarat batas bahwa jenis fluida adalah hidrokarbon apabila dipenuhi dan air jika tidak memenuhi persyaratan.

2. Menentukan nilai porositas

3. Menentukan nilai saturasi air

4. Menentukan ketebalan lapisan hidrokarbon dan letak kedalamannya. C. Data Hasil Pengolahan LoggingDepthVshSw DepthVshSw DepthVshSw

PRAKTIKUM KE-II

PETA ISOPACH DAN BULK VOLUME

A. Teori Dasar

Peta isopach adalah peta geologi dimana konturnya dibuat berdasarkan ketebalan lapisan yang sama. Pengertian dari ketebalan lapisan disini adalah ketebalan lapisan produktip yang diperkirakan mengandung hidrokarbon berdasarkan hasil interpretasi data logging.

Kegunaan dari peta isopach ini adalah untuk menentukan besarnya volume batuan reservoir (bulk volume). Di samping itu juga dapat digunakan untuk memprediksikan nilai ketebalan lapisan produktip (lapisan hidrokarbon) apabila akan dilakukan suatu penambahan titik serap atau pengembangan sumur-sumur eksploitasi yang baru dalam program peningkatan produksi lapangan.

Untuk menentukan besarnya nilai bulk volume (Vb) dari peta isopach adalah dengan melalui tahapan-tahapan sebagai berikut ini :

1. Siapkan tabel sebagai berikut ini :

KonturA*

A(acre)

h

(ft)AturanVb(acre-ft)

A* = luas kontur hasil pembacaan A = luas kontur sebenarnya2. Hitung luas per interval kontur (A*) dengan alat planimeter atau melalui kertas grafik kartesian (kertas grafik millimeter) apabila alat planimeter tidak tersedia.

3. Hitung luas per interval kontur yang sebenarnya (A) dalam satuan acre dengan mengkoversikannya terhadap skala peta isopach yang digunakan.

A = A* x skala peta4. Hitung bulk volume per interval kontur dengan menggunakan aturan pyramidal atau aturan trapezoidal.

Aturan pyramidal jika :

Aturan trapezoidal jika :

5. Hitung total bulk volume : Vb = Vbn

PRAKTIKUM KE-III

ANALISA POTENSI HIDROKARBON

DENGAN DECLINE CURVE

A. Teori Dasar

Decline curve adalah suatu metoda untuk mengetahui potensi hidrokarbon yang terkandung didalam suatu reservoir (lapangan) hanya berdasarkan data produksi yang terdiri atas : laju produksi, kumulatip produksi dan waktu produksi. Dengan demikian metoda decline curve ini akan dapat diterapkan apabila suatu lapangan telah cukup lama diproduksikan.

Keunggulan metoda decline curve ini dibandingkan dengan metoda volumetric adalah juga dapat menentukan umur produksi dan prediksi laju produksi untuk masa yang akan datang. Konsep dasar dari metoda decline curve ini untuk tujuan yang tersebut diatas adalah melalui analisis penurunan produksi terhadap waktu. Dengan demikian metoda ini akan sangat akurat apabila lapangan tersebut telah selesai dilakukan proses pengembangan sumur (tidak ada penambahan sumur), sehingga produksi menurun semata-mata terjadi hanya diakibatkan oleh semakin kecil hidrokarbon yang terkandung didalam reservoir di lapangan tersebut.

Konsep metoda decline curve ini pertama kali diterapkan oleh J.J. Arp dimana penurunan laju produksi terhadap waktu dinyatakan dalam bentuk persamaan :

Np =

Dimana :

Qo = laju produksi

t = waktu produksi

Np = kumulatip produksi

a = konstanta

b = konstanta loss ratio

Untuk mengkaji tujuan yang akan dicapai dengan metoda decline curve ini J.J. Arp membagi kurva penurunan produksi dalam 4 (empat) bagian yaitu : straight decline, exponential decline, harmonic decline dan hyperbolic decline. Pembagian keempat jenis kurva ini adalah berdasarkan nilai konstanta loss-ratio.

Melalui penjabaran konsep persamaan penurunan laju produksi terhadap waktu dan system pembagian loss-ratio, selanjutnya J.J. Arp mendapatkan criteria-kriteria persyaratan untuk keempat jenis kurva penurunan produksi.

2. In Q0 vs In Np1. Garis lurus

2. LnQo = aLnNp + b

Langkah kerja untuk menerapkan metoda decline curve ini adalah sebagai berikut : 1. Siapkan data laju produksi (Qo), kumulatip produksi (Np) dan waktu produksi (T).

2. Buat plot laju produksi dan waktu produksi dalam skala semilog

3. Tentukan jumlah data (N) yang memenuhi persamaan garis lurus dari hasil langkah ke-2 secara trial & error hingga didapatkan nilai koefisien korelasi diatas 0,85 ( R 0,85).

4. Tentukan persamaan garis lurus untuk keempat jenis kurva berikut koefisien korelasi (R), koefisien determinasi (R2) dan standar deviasi (SD) dengan menggunakan data hasil langkah ke-3.5. Tentukan jenis kurva decline curve yang paling sesuai untuk diterapkan berdasarkan criteria nilai SD yang terkecil.

6. Tentukan jumlah cadangan (Np), umur produksi (T) dan produksi masa yang akan datang berdasarkan bentuk persamaan yang sesuai dengan jenis decline yang telah diperoleh. B. Tujuan Praktikum

1. Menentukan jenis kurva decline curve dan persamaan garis lurusnya

2. Menentukan jumlah cadangan hidrokarbon di insitu dan sisa cadangan

3. Menentukan umur produksi lapangan
