Approval proposal for TAC prolongation will be signed in 2017

Current condition of oil production facilities in Gelam Field are still unadjusted with standard roles of SKPP Migas*) .pdf

Factual on field :o ex-used tubing are applied for flow line SG 16/18 to the manifold lineo non standard API pumps are still applied on the operation

To meet SKPP Certification oil facility in Gelam Field must be propered In other hand, we have to evaluate effectiveness and feasibility of oil facility

for Gelam continuous operation

ATTACHMENTS

LOGOPROBLEMS

1. How to select the proper oil surface production facility o applied tubing for flow line to the manifold lineso applied pipeline from manifold to the separator o pump line sizing and recommended pump to drive oil to the

storage tank then purpose it to the Kenali Asam (PertaminaOil Station)

2. How to spare effectiveness Gelam Oil Plant for initial design and current operating condition nowday

3. How to make an analysis based on the sparing result

LOGOCONSTRAINS

Well data analysis is based on Gelam Oil Production in Jan-Aug 2011

Analysis is focused to proper select flowline, pipeline, and oil pump There are four well which will be calculated for their flow line

analysis Flowline is consider to the two phase flow analysis (liquid & gas) Flowline and pipeline analysis is based on proper criteria of

dimension, pressure drop, and highway road crossing Scope of pipeline analysis is for manifold lines and pump line Pump selection is based on proper criteria NPSHa, type, head, and

its power Pump line modification is only for line of oil shipping pump II Only flowline from dual completion SG 16/18 which applied ex-used

tubing to the manifold. Heat transfer in control volume analysis is negligible

LOGO

Solusi : Jika kecepatan aliran gas tetap dijaga cukup tinggi, slug tidak akan

terbentuk karena gas mengangkut liquid keluar menuju outlet begitu cepat sehingga fraksi liquid akan tetap rendah di sepanjang pipa.

Terkadang hal ini memungkinkan untuk diambil keuntungan dalam segi operasional atau mampu memberikan rekomendasi operasional yang mendefinisikan bagaimana saluran pipa harus dioperasikan, dengan mendefinisikan tingkat minimum laju alir gasagar terbebas dari mekanisme terbentuknya slug.

LOGOTUBE and PIPE DIFFRERENCE

TUBE Kelebihan tubing :

1. dinding lebih tebal2. stress value lebih tinggi sehingga memiliki mechanical strength-nya lebih baik

Kekurangan tubing :instalasi pemasangan lebih mahal sebab metode penyambungannya menggunakan collar yang harus dilas pada kedua bagian sisinya (kurang simple dibanding pipa)

Tube size berdasarkan outside diameter dengan ketebalan dinding tube ditulis sesuai dengan angka exactnya.

PIPE Pipe size diidentifikasikan dengan ukuran nominal, ketebalan dinding pipa dengan angka

schedule

Contoh :Pipa = Seamless pipes DN100 sch 40 Mild SteelTube = Cu Tube OD 20mm thickness 2mm

LOGO CENTRIFUGAL PUMPS ( CONSIDERATION )

Berikut ini adalah beberapa keuntungan pompa sentrifugal dibandingkan jenis pompaperpindahan positif ( Lazarkiewics, 1965 ) :

o Gerakan impeler yang kontinyu menyebabkan aliran tunak dan tidak berpulsao Keandalan operasi tinggi disebabkan gerakan elemen yang sederhana dan tidak

adanya katup-katupo Kemampuan untuk beroperasi pada putaran tinggi, yang dapat dikopel dengan

motor listrik, motor bakar atau turbin uapo Ukuran kecil sehingga hanya membutuhkan ruang yang kecil, lebih ringan dan

biaya instalasi ringano Harga murah dan biaya perawatan murah


LOGO ANSI PUMP and API PUMP DIFFERENCE


Pada dasarnya pemilihan dari apakah kita akanmenggunakan pompa API atau non-API adalahtergantung dari keputusan kita sendiri atauperusahaan yang akan menggunakan pompatersebut.

Biasanya sebuah perusahaan/pabrik telahmemiliki standar tentang pemilihan pompaapakah akan menggunakan pompa API ataunon-API.

Jika kita menginginkan pompa yang benar-benarbagus untuk memompa fluida dengantemperature yang tinggi, maka yang paling amanadalah menggunakan pompa API,

namun bila keuangan menjadi kendala, kita bisamemilih pompa non-API dengan kualifikasi yang di syaratkan oleh pompa API tapi denganmodifikasi sehingga tidak semahal pompa API.

• The viscosity of fluids pumped influences the pump's performance and efficiency.

• Viscosity influences the friction loss of all the components of the system and the heat transfer rate of the system
