Abstract

ST-X crude oil exhibits waxy characteristics with an initial pour point of 22°C, which is very close to the field fluid temperature of 21.1°C, potentially causing flow disturbances and paraffin crystal formation. This study aims to evaluate the effect of varying concentrations of Pour Point Depressant (PPD) on pour point reduction through laboratory testing. A 1-Liter crude oil sample was divided into five portions (0.2 L each) and injected with PPD at concentrations of 5, 10, 15, 20, and 25 ppm, followed by cooling bath testing to determine the pour point values. The results indicate that increasing PPD concentration progressively reduced the pour point, reaching 13°C at 25 ppm. From technical and economic perspectives, 10 ppm is recommended as the optimum dosage, as it effectively maintains oil flowability under field operating conditions.

Abstract

The problem of air emulsion in crude oil is a significant challenge in the oil and gas industry because it reduces product quality and process efficiency. This study examined the effectiveness of demulsifiers on different types of crude oil by centrifugation and bottle test methods to separate water-oil emulsions. In Hassi Berkine crude oil, the REB09305 OS deemulsifier is effective at a low dose of 20 ppm with a 100% air discount at room temperature and centrifugation at 1200 rpm for 45 minutes. At the Main Oil Station (MOS) Menggung, the optimal dose of 200 ppm provided the lowest BS&W value of 1.6% using a combination of bottle test and centrifuge methods. In Bentayan oil, the B demulsifier with -OH group showed the best performance at a dose of 30 ppm and a temperature of 60°C with a BS&W of 0.1%. The use of a demulsifier according to specific doses and optimal conditions has been shown to improve the efficiency of emulsion indicators, reduce BS&W and salt content, and reduce the risk of corrosion.

Abstract

Drilling mud plays an important role in oil and gas drilling operations as it functions to transport cuttings, maintain wellbore stability, and control formation pressure. The performance of drilling mud may deteriorate due to contamination, one of which is seawater contamination that can affect the pH value and rheological properties of the drilling mud. This study aims to analyze the effect of seawater contamination on the pH and rheological properties of drilling mud used in Well "IM" of the "ME" Field. This research employed a quantitative method with an experimental approach conducted at the Drilling Laboratory of Sekolah Tinggi Teknologi Migas Balikpapan using seawater contamination levels of 1%, 3%, 5%, 7%, and 9%. The parameters evaluated were pH, Plastic Viscosity (PV), Yield Point (YP), and Gel Strength at 10 seconds and 10 minutes. The results showed that increasing seawater contamination reduced the quality of the drilling mud. The pH value decreased from 8.61 to 5.80, while Plastic Viscosity (PV) decreased from 12 cP to 6 cP, Yield Point (YP) from 31 lb/100 ft² to 21 lb/100 ft², Gel Strength at 10 seconds from 13 lb/100 ft² to 8 lb/100 ft², and Gel Strength at 10 minutes from 15 lb/100 ft² to 10 lb/100 ft².

Abstract

Lumpur pemboran berbasis air (Water-Based Mud/WBM) menawarkan alternatif yang lebih ekonomis dan ramah lingkungan dibanding lumpur berbasis minyak (Oil-Based Mud/OBM) dalam operasi pengeboran minyak dan gas. Namun, tantangan teknis seperti stabilitas formasi, kehilangan sirkulasi, serta dampak lingkungan dari aditif kimia masih menjadi kendala utama. Penelitian ini mengkaji efektivitas formulasi WBM melalui tinjauan sistematis terhadap tiga studi utama: perencanaan WBM dengan barit dan CaCO? untuk formasi bertekanan tinggi (Junianto dkk., 2017), analisis toksisitas WBM dengan barit dan KCl (Miranti dkk., 2014), serta studi penggunaan CaCO? dari cangkang telur sebagai aditif alami (Rante dkk., 2024). Hasil kajian menunjukkan bahwa formulasi WBM dengan barit dan CaCO? efektif dalam mencegah kick dan lost circulation pada pengeboran formasi bertekanan tinggi. Namun, uji toksisitas mengungkap bahwa beberapa formulasi WBM melebihi batas aman kandungan logam berat, khususnya Cu dan Pb, yang berpotensi mencemari lingkungan. Di sisi lain, penggunaan CaCO? dari cangkang telur sebagai aditif alami terbukti mampu meningkatkan plastic viscosity dan yield point secara signifikan, sekaligus mengurangi filtrate loss, dengan dampak lingkungan yang lebih rendah. WBM memiliki potensi besar sebagai lumpur pemboran yang efisien dan berkelanjutan, dengan catatan bahwa formulasi aditif harus dioptimalkan baik dari aspek teknis maupun lingkungan. Penggunaan bahan alami seperti CaCO? dari cangkang telur dapat menjadi solusi inovatif untuk meningkatkan performa reologi sekaligus mengurangi dampak negatif terhadap lingkungan. Rekomendasi pengujian toksisitas dan regulasi yang ketat terhadap kandungan aditif kimia diperlukan untuk memastikan keberlanjutan penggunaan WBM dalam industri pengeboran.
