Perkembangan penelitian mengenai polyamine sangat pesat diberbagai belahan dunia dewasa ini. Salah satunya disebabkan karena pemakaian KCl memberikan efek negatif di lingkungan sekitarnya. Penelitian kali ini menyajikan perbandingan unjuk kerja antara Polyamine dan KCl berdasarkan observasi laboratorium. Parameter yang digunakan dalam pengujian ini meliputi swelling clay dan rheology (Gel Strength). Hasil dari penelitian ini menunjukkan bahwa unjuk kerja dari 2% Polyamine setara dengan 7% KCl polymer.

Corrosion is a problem that occurs in the production system of industrial oil and gas. Control corrosion in tubing production is necessary for maintaining production and well direct as tubing production is the first contact with corrosion fluid and material agent. Corrosion is caused by a chemical reaction between a material and corrosion fluid. A corrosion rate prediction model can be used to predict its rate such as NORSOK and de Waard models. Both methods are used in Olga Simulator software by Schlumberger company that will be used in this paper. Some of the parameters and scenarios that influence corrosion are tested. Evaluation of reservoir pressure 40 bar, 45 bar, 50 bar, temperature 100℃, 125℃, 150℃, mono-ethylene glycol 0%, 20%, and 80% with 66,7%IE and 79,7%IE were used as corrosion inhibitors for looking at the best scenario.

Loss circulation is a major problem and known as the biggest challenge during drilling and well construction.This can leadsto various consequences,such as stuck pipe, loss of material and time to combat the losses, and even losing the well itself. Severe loss circulation conditions are often met while drilling geothermal wells in Indonesia. Partial to total losses have start experienced since drilling the surface section. Cement plugs is one of the conventional methods to cure losses. Number of cement plugs differ from one well to another well. Even in some wells, number of cement plugs performed for loss circulation plug can be over 30 times with total of more than 4,000 barrels of cement slurry pumped. Solution other than basic loss circulation material and cement plug must be developed to optimize curing loss time. Engineered fiber base concentration which is include; Base Fluid, LCM and Solid Package was obtained from simulation, then trial and error in laboratory was conducted. Based on the final recipe, the control pill was able to hold pressure and not leaking, even when using 5 mm grid clearance. Additional combined stiff fiber and flexible fiber with concentration of 6 lbs/bbl sufficient to hold exessive loss circulation.

Aiming for productive fault in Suban Agung Rim, Field X Cluster Y Bengkulu Province, Indonesia, PT Pertamina Geothermal Energy (PGE) drilled some wells to discover the potential awaited. However there are challenge awaits each meter ahead especially in reservoir sections where loss circulation is expected. Knowing the risk, PGE decided to drill the well utilizing aerated drilling. The method has known for decades to be the most effective approach in dealing loss circulation. The method applies certain value of compressed air to be injected in fluid stream, so bubbling process can be achieved in order to reduce the mud weight. The method has benefit to maintain ROP and minimize the risk for pipe get stuck due to poor hole cleaning in fractured formation. There are three wells drilled in Field X Cluster Y which has the same problem in 9-7/8” section; all experienced stuck pipe while drilling. During the process aerated drilling was utilized, however it was not sufficient. This paper will discuss and explain on how the occurrence happened and what to do next in similar condition to avoid the problems.

Simulation Study of Hot Waterflood and WASP Injection Post Mature Steamflood Ludovika Jannoke; Iwan Setya Budi; Astra Agus Pramana

Steamflood is the most successful thermal EOR applied throughout the world and have produced the biggest portion of oil from EOR methods. As high intensity energy and associated cost are put to produce oil, optimization in any level can have tremendous impacts. Optimization in steamflood operation can be achieved by optimizing steam injection (rate, time), especially in mature pattern/ field or nearing the end of field life/ abandonment. This objective can be done thru utilization of retained heat in the reservoir and overburden/ underburden as they are not instantaneously produced with fluids. By using reservoir simulation, it can be shown that injection is not necessary to be continue until abandonment but can be stopped at a much earlier time hence a much profitable steamflood operation can be achieved.

Penggunaan busa CO2 untuk metode injeksi cenderung tidak stabil dalam pembentukan stabilitas dari busa. Karena hal itu, dibutuhkan penguat untuk menambahkan stabilitas busa yang terbentuk. Pada penelitian ini, menggunakan nano abu batubara dan nano silika serta polimer berupa xanthan gum sebagai penguat busa. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dengan penambahan nano dan polimer pada stabilitas busa, perbandingan penggunaan nano abu batubara dan silika dalam uji stabilitas busa serta penelitian ini juga bertujuan untuk mengetahui penguat apa yang dapat meningkatkan stabilitas busa secara signifikan. Metode yang digunakan pada penelitian ini menggunakan metode uji laboratorium yang dimulai dari proses milling sampel, karakterisasi sampel, hingga pengujian stabilitas busa. Pengujian stabilitas busa menggunakan metode yang menghitung waktu halftime. Hasil dari pengujian stabilitas busa ini didapatkan bahwa penambahan nano silika dan nano abu batubara memiliki peningkatan waktu halftime sebesar 10.23% dan 2.96% dibandingkan tidak menggunakan nanopartikel. Campuran dari nanopartikel dan polymer berupa xanthan gum dapat meningkatkan waktu halftime 12.65% untuk nano silika dan 6.33% untuk nano abu batubara. Sedangkan campuran nanopartikel, polimer, dan minyak mengalami penurunan 10.9% untuk nano silika dan 16.29% untuk nano abu batubara. Berdasarkan hasil analisis data percobaan yang sudah dilakukan, penambahan nano silika memiliki nilai stabilitas busa yang lebih tinggi dibandingkan nano abu batubara serta penambahan nano silika dan polimer merupakan penguat yang paling baik dalam menjaga stabilitas dari busa yang dihasilkan.
