Abstract

Enhancing the cement strength through attaching chemical additive has been popular to meet the required condition for a particular well-cementing job. However, due to a low oil-price phenomenon, pouring and additive should be reconsidered because it can raise the cost and make the project become uneconomic. Another additive material in nanocomposite form will be introduced through this experimental study. The nanocomposite material consist of silica nanoparticle, known as “Nanosilica” and a palm-shell-waste, which is abundant in Indonesia. Before making a nanocomposite, the palm-shell should be burned to obtain a charcoal form, ground and sieved to attain a uniform size.   The study focuses on the two parameters, compressive strength and shear bond strength, which can reflect the strength of the cement. These values are obtained by performing a biaxial loading test to the cement sample. Various samples with different concentration of nanocomposite should be prepared and following the mixing, drying, and hardening process before the loading test is carried out. The result from the test shows a positive indication for compressive strength and shear bond strength values, according to the representative well cementing standards. Increasing the nanocomposite concentration on the cement will increase these values. Furthermore, an investigation on the temperature effect confirms that the sample with 700oC burning temperature have highest compressive-strength and shear-bond-strength values. This is a potential opportunity utilizing a waste-based material to produce another product with higher economic value.

Abstract

Salah satu parameter penting dalam pengembangan lapangan panas bumi disektor listrik adalah besarnya potensi listrik di reservoir. Potensi listrik ini dijadikan sebagai panduan awal dalam rencana kapasitas pembangkit yang akan dibangun. Penentuan potensi listrik ini akan menjadi sulit jika data luas reservoir belum ada. Studi ini menggunakan data pengukuran tekanan dan temperature di sumur-sumur eksplorasi pada lapangan X. Dari data temperature dibuat menjadi peta iso temperature. Berdasarkan peta iso temperature, luas reservoir Lapangan X diperkirakan 20 km2. Hasil kalkulasi potensi listrik menunjukkan Lapangan X mempunyai potensi listrik 40 MWe selama 30 tahun. Ini berarti kapasitas pembangkit maksimum di lapangan X adalah 40 MWe.

Abstract

Injeksi polimer merupakan injeksi air yang disempurnakan. Penambahan polimer ke dalam air injeksi bertujuan untuk memperbaiki sifat fluida pendesak untuk meningkatkan perolehan minyak. Akan tetapi mekanisme pendesakannya sangat kompleks. Salah satu kendalanya adalah terjadi pengurangan permeabilitas. Pengurangan permeabilitas sebenarnya merupakan dampak yang ditimbulkan pada aliran fluida dalam media berpori. Penelitian ini  akan membahas mengenai efek pengurangan permeabilitas terhadap laju injeksi polimer dengan berbagai kenaikan viskositas. Hasil penelitian memperlihatkan efek pengurangan permeabilitas akan berdampak pada penurunan laju injeksi polimer. Selain itu, dengan meningkatnya viskositas, Juga berdampak pada penurunan laju injeksi polimer.

Abstract

Designing a slurry with adequate strength resistance is a major objective in oil and gas completion job. Various studies and research confirms that Compressive Strength (CS) and Shear Bond Strength (SBS) are two parameter which is imperative in describing cement strength in well cementing job. This experimental study introduces a Rice Husk Ash (RHA), an alternative cement additive derived from organic waste. RHA rich in silicon oxide (SiO2) and has a pozzolanic reaction, which is correlated in enhancing cement strength. Serial cement samples with various concentration of RHA were prepared to investigate the effect of RHA concentration to CS and SBS. All samples were then Dried for 24 hours in room condition after completing mixing and molding process. A Biaxial Loading test was then performed to all samples to determine the CS and SBS values by using hydraulic press apparatus. Results from the loading test generally indicate an enhancement of CS and SBS for samples with 31%, 32%, 33%, and 34% RHA. An indication of higher CS and SBS is not found for sample with 35% RHA, comparing with 34% RHA. Thus, 34% RHA is the optimum concentration for theses study, which yield 1312. psi of CS and 158.16 psi of SBS.  Through this study, there is an opportunity for transforming waste material into alternative additive with higher economic value.

Abstract

Lumpur pemboran merupakan salah satu faktor yang paling penting dalam suatu operasi pemboran..Permasalahan yang sering muncul dalam sirkulasi lumpur pemboran salah satunya berupa lost circulation. Untuk menanggulangi permasalahan lost circulation maka perlu ditambahkan LCM..Penelitian ini menggunakan ampas tebu sebagai bahan LCM. Ampas tebu memiliki kandungan karbon yang tinggi berupa selulosa sebesar 26-43% dan hemiselulosa sebesar 17- 23%. Penambahan ampas tebu kedalam lumpur standar dengan massa additive 1, 1,5 , 2 dan 2,5 gr kemudian di mixer selanjutnya lumpur tesebut dipanaskan dengan temperatur 80oF dan 140oF. Berdasarkan hasil penelitian penambahan ampas tebu pada lumpur pemboran yang digunakan sebagai loss circulation material (LCM) dengan konsentrasi dan temperatur tertentu dikatakan efektif untuk mencegah terjadinya permasalahan loss circulation. Dari hasil pengujian rheology lumpur pemboran yaitu densitas, viskositas, plastic viscosity, yield point, dan gel strength dengan penambahan massa additive ampas tebu dapat meningkatkan nilai rheology lumpur pemboran, namun seiring dengan kenaikan temperatur hingga 140oF mengakibatkan penurunan nilai rheology lumpur. Hasil pengujian filtration loss semakin banyak penambahan massa additive dan semakin tinggi temperatur maka nilai filtration loss akan menurun sedangkan pada pengujian mud cake dengan penambahan massa additive dan kenaikan temperatur mengakibatkan nilai mud cake semakin bertambah

Abstract

The increasing volume of produced water from oil and gas production requires effective handling before reinjection or disposal. Produced water contains minerals, oil, and other contaminants, making separation processes at refineries insufficient. This study investigates the use of reverse demulsifiers, specifically surfactants (Alkyl Phenol Ethoxylate – APEOs and Natrium Lignosulfonate – NLS), to separate emulsions in produced water. Surfactants reduce surface tension between oil and water, facilitating contaminant removal. Using a jar test apparatus, experiments varied surfactant dosage, stirring speed, and stirring time to determine optimal conditions for achieving water quality standards. Results indicate differences between APEOs and NLS in removing contaminants. APEOs, at 5 ppm, 130 rpm, and 5 minutes, achieved a COD concentration of 80.33 mg/L, while NLS, at 5 ppm, 220 rpm, and 10 minutes, yielded 77.48 mg/L. Both are well below the quality standard of 200 mg/L, proving the effectiveness of this approach. This study highlights the potential of APEOs and NLS as reverse demulsifiers for produced water treatment. Proper application could enable safe reuse or environmentally sound disposal, providing an effective solution to managing produced water in the oil and gas industry.
