• Pressure Loss
• TPC
Diketahui Sumur “ TP-1 “
• Tekanan gradient = 0.465 Psi/ft
• Tekanan Reservoir = 2000 Psi
• Densitas minyak = 0.87 = 30 0 API
• Kedalaman sumur Perforasi = 1000 ft
Overview
Fenomena Natural Flow
Jawab :
• Tekanan kolom setinggi 1000 ft adalah :
Kesimpulan : Mengalirkan minyak secara “ Sembur Alam “ ( Natural Flow)
• Tekanan yang tersisa sampai “ Surface “ ( kedalaman 0 ft ) adalah :
= Tek. Reservoir – Tekanan kolom ( 1000 ft )
= 2000 Psi – 404.5 Psi → 1595.5 Psi
= P. Gradient Sea W xkedalaman x densitas oil
= 0.465 psi/ft x 1000 ft x 0.87 → 404.5 Psi
Diketahui Sumur “ TP-1 “
• Tekanan gradient air laut = 0.465 Psi/ft
• Tekanan Reservoir (turun s/d) = 400 Psi
• Densitas minyak = 0.87 = 30 0 API
• Kedalaman sumur Perforasi = 1000 ft

Jawab :
• Tekanan kolom setinggi 1000 ft adalah :

Gaslift
Hal-hal yang harus di perhatikan dalam perencanaan Gas Lift:
1. Kedalaman titik injeksi optimum 2. GLR injeksi optimum.
3. Tekanan gas injeksi yang diperlukan.
4. Pemilihan ukuran port valve yang tepat.
Persyaratan suatu sumur menggunakan Gas Lift antara lain :
1. Laju produksi yang tinggi 2. Produktivitas yang tinggi 3. Kelarutan gas yang tinggi
4. Bottom Hole Pressure (BHP) agak tinggi.
Overview
ESP (Electric Submersible Pump)
• ESP sering disebut sebagai Pompa REDA (Russian Electro Dynamo of Arutunoff)
• Pompa sentrifugal bertingkat banyak yang terdiri dari “Motor” (Impeller) dan Stator (Diffuser)
• Semakin banyak tingkatan stator-stator ,
maka semakin tinggi Head pompanya
dan semakin besar laju produksi yang di
peroleh.
Overview
Rod Pump (SRP & HPU)
Persyaratan suatu sumur menggunakan Rod Pump antara lain : 1. Kecepatan produksi rendah dan lemah.
2. PI yang rendah 3. BHP yang rendah 4. GOR yang rendah
