Abstract

Mengestimasikan cadangan minyak dan gas termasuk dalam kegiatan yang utama dalam merencanakan pengembangan lapangan migas. Data yang tersedia atau parameter adalah hal penting untuk memperkirakan besarnya cadangan. Pada kegiatan eksplorasi, informasi data yang ada bisa dibilang sangat sedikit atau terbatas menyebabkan keakuratan dari data yang didapatkan umumnya tidak pasti. Pendekatan secara probabilistik dapat membantu mengurangi faktor ketidakpastian. Simulasi Monte Carlo menggunakan metode dimana perhitungannya dilakukan berdasarkan ketersediaan data lapangan yang masih belum lengkap pada variabel input dan dinyatakan dengan distribusi probabilitas, agar mendapatkan hasil yang tepat dalam bentuk distribusi probabilitas. Perhitungan cadangan hidrokarbon pada lapangan “AT” menggunakan dua distribusi probabilitas yaitu distribusi konstan dan distribusi segitiga. Dengan menggunakan metode Monte Carlo, perkiraan .cadangan minyak di lapangan “AT” menghasilkan rata-rata sebesar 55,95 MMSTB dan gas 27976 MMSCF. Besarnya Most Probable pada minyak didapatkan dengan nilai 42,75 MMSTB dan Gas 21394 MMSCF, Cadangan minimum minyak yaitu 7,131 MMSTB dan gas 3565,67 MMSCF, nilai cadangan maximum minyak yaitu 135,50 MMSTB dan gas 67747,81 MMSCF.

Abstract

Proses pemboran minyak menghadapi risiko kick—masuknya fluida formasi ke kolom bor—yang berpotensi memicu blowout. Sistem Blowout Preventer (BOP) mengandalkan adaptor flange 13- 5/8” berkapasitas 5.000 psi dan 10.000 psi sebagai antarmuka penahan tekanan. Penelitian ini menganalisis desain flange melalui evaluasi ketebalan minimum, area kritis, dan validasi material. Metode analitis berbasis standar American Petroleum Institute (API) menghitung tekanan desain (67.500 psi) dan kekuatan material (84.324 psi), menghasilkan margin keamanan 25%. Simulasi ketebalan minimum flange 13-5/8” menunjukkan ketebalan desain teoritis 0.529” (dipengaruhi tekanan internal dan tegangan izin material), sedangkan ketebalan aktual 0.419” tetap memenuhi safety factor. Analisis area kritis pada flange 5.000 psi mengidentifikasi konsentrasi tegangan di dua lokasi: 2.58” (daerah transisi geometri) dan 1.20” (sekitar bolt hole), yang direkomendasikan untuk dioptimalkan melalui fillet radius. Studi membuktikan desain flange memenuhi integritas struktural untuk kedua level tekanan, dengan ketebalan aktual lebih rendah akibat pendekatan konservatif persamaan Barlow. Hasil ini memvalidasi efisiensi material dan geometri komponen tekanan tinggi, mengurangi risiko kegagalan katastropik selama operasi pemboran. Implikasi praktisnya mencakup penguatan desain berbasis simulasi tegangan dan optimasi lokal pada area rentan, menjamin keandalan sistem BOP dalam skenario tekanan ekstrem.

Abstract

The Bintuni Basin is one of the largest hydrocarbon-bearing basins in Eastern Indonesia, although only a limited number of oil and gas fields are currently. Consequently, further investigation into its petroleum system, particularly the potential of its source rocks. In hydrocarbon exploration, characterizing source rock is critical to evaluating the presence of organic-rich strata capable of generating hydrocarbons. Geochemical analysis is a widely used method for assessing source rock potential, utilizing total organic carbon (TOC), rock-eval pyrolysis, and vitrinite reflectance data. In this study, geochemical data were obtained from one well and two outcrop samples to evaluate the quantity, quality, and thermal maturity of organic matter. The geochemical assessment of rock samples from four stratigraphic formations indicates that the Permian Ainim Formation exhibits the highest source rock potential. TOC values range from 1% to 80% with hydrogen index (HI) values range between 13 and 431 mg HC/g TOC classifying the formation as a good to excellent potential. The dominant organic matter consists of kerogen type II/III suggesting the potential for both oil and gas generation. Thermal maturity analysis indicates that the Ainim formation has reached the oil and gas generation window at depths of 8,075–8,420 feet. These findings demonstrate that the Ainim Formation represents a significant source rock within the Bintuni Basin, contributing valuable insights into the region's petroleum system and hydrocarbon prospectivity.

Abstract

The length of time to produce reservoir fluid will definitely experience a decrease in the production rate. The decrease in production rate can be caused by inappropriate tubing sizes and Damage to formations that impede fluid flow.To overcome the decline in production rates, it is necessary to choose the appropriate tubing size and carry out acidizing activities. Appropriate tubing size can avoid pressure drop and extend the life of the well. Acidizing is the injection of acid to eliminate the effect of decreasing permeability. The tubing size of 2 7/8 inches is not suitable for the “REDD-24” well because the target Qopt value of 130.997 bfpd was not achieved and there was an indication of calcium carbonate scale in the formation. This study discusses production optimization by re-designing tubing id after acidizing. Calculating the inflow performance relationship (IPR) using the Wiggin's method and obtaining Qtmax results of 163.74583 bpd, calculating theProductivity Index (PI) of 0.0870911 psi which according to Kermit E. Brown, the PI value is classified as low, calculates the skin value and obtains the results (+) 37.35 which indicates that the formation of the "REDD-24" well has suffered formation Damage. Selection of tubing with Hagedorn & Browns's correlation, analyzing Qopt tubing sizes of 3 1/2 inches, 2 inches, 1 2/3 inches, and 1 1/3 inches. Choose tubing with a size of 1 1/3 inches. matrix acidizing planning by knowing the value of formation fracture pressure (Pf) of 4857 psi, maximum  injection rate (Imax) of 2.829 bbl/min, maximum injection pressure (Pmax) of 1318.24, injected acid volume of 42.13561 bbl, and knowing success rate.

Abstract

Acid Mine Drainage (AMD) represents a critical environmental challenge in coal-mining regions, particularly due to its long-term impacts on surface water quality and surrounding ecosystems. This study investigates the lithological controls on AMD formation in the Sungai Seluang area, East Kalimantan, Indonesia, through an integrated rock characterization approach. The novelty of this research lies in linking detailed lithological attributes and pyrite micro-morphology with AMD generation potential and its implications for riverine water systems. Macroscopic lithological observations were combined with standardized pH testing (SNI 6989.11:2019) and Scanning Electron Microscopy (SEM) to evaluate the acid-generation characteristics of representative rock units. The results indicate that 92% of the analyzed samples are classified as Potentially Acid Forming (PAF), while only 8% are Non-Acid Forming (NAF). The study area is lithologically dominated by claystone (42%), sandstone (31%), and shale (27%), all of which commonly exhibit intense oxidative staining, pervasive fracturing, and weathering features that significantly enhance sulfide exposure to oxygen and water. SEM analyses reveal the presence of both euhedral and framboidal pyrite, with framboidal pyrite identified as particularly reactive and influential in accelerating acid production. Measured pH values are predominantly acidic (<6), indicating a high AMD potential that poses a serious threat to the Sungai Seluang system through acidification and metal mobilization. These findings demonstrate that lithology and micro-scale mineralogical characteristics play a decisive role in controlling AMD formation and its environmental consequences. The integrated approach adopted in this study provides a robust framework for early AMD source identification and supports the development of more effective geochemical management strategies aimed at protecting water quality and minimizing long-term environmental degradation in coal-mining areas.
