<![CDATA[Penelitian ini bertujuan untuk mengevaluasi litologi di dalam sumur menggunakan metode overlay log densitas dan log neutron. Metode overlay log menggabungkan data dari kedua jenis log sumur untuk mendapatkan pemahaman yang lebih komprehensif tentang litologi. Dalam penelitian ini, data densitas dan log neutron digunakan untuk mengidentifikasi jenis litologi dalam formasi geologi yang diteliti. Metode overlay log digunakan untuk membandingkan dan menganalisis pola serta distribusi litologi yang dihasilkan dari kedua log tersebut. Penelitian ini memberikan pemahaman yang lebih baik tentang karakteristik litologi di dalam sumur dan informasi penting untuk kegiatan eksplorasi dan eksploitasi sumber daya alam di dalam formasi tersebut. Hasil penelitian ini meningkatkan pemahaman tentang kompleksitas litologi di daerah yang diteliti dan berpotensi menjadi dasar pengambilan keputusan yang lebih baik dalam aktivitas geologi dan industri perminyakan. Metode overlay yang melibatkan log densitas dan log neutron dalam skala logaritmik, serta penggunaan skala yang sesuai dengan jenis batuan seperti sandstone, limestone, dan dolomite, digunakan untuk mengidentifikasi jenis litologi batuan. Jika terjadi pertemuan antara kurva densitas dan neutron pada bagian formasi yang bersih dan kedua kurva tersebut berhimpit dengan skala yang cocok dengan jenis batuan, maka jenis litologi sebenarnya dapat ditunjukkan. Hasil penelitian pada sumur DJ-1 dan DJ-2 menunjukkan adanya jenis litologi sandstone.]]>

<![CDATA[Dalam memproduksikan gas bumi tentunya terdapat hal yang perlu diperhatikan, salah satunya fenonema liquid loading. Liquid loading terjadi karena sejumlah liquid yang terakumulasi dalam sumur gas yang diakibatkan kecepatan gas yang mengalami penurunan sehingga fasa gas tidak mampu mengangkat liquid ke permukaan. Dalam penelitian ini dilakukan analisis perkiraan liquid loading pada 3 sumur kandidat di Lapangan MLT dengan menggunakan persamaan Turner untuk menghitung laju alir kritis (Qcrit) pada setiap sumur. Apabila Qg < Qcrit, maka diindikasikan terjadi liquid loading pada sumur tersebut. Hasil analisis perkiraan liquid loading pada 3 sumur kandidat menunjukkan bahwa Sumur MT-04 terindikasi mengalami liquid loading dimana Qg berada dibawah Qcrit dengan laju alir kritis gas (Qg) masing – masing sumur diperoleh hasil sebesar 22,331 MMscf/d untuk Sumur MT-04, 21,962 MMscf/d untuk Sumur MT-05, dan 21,702 MMscf/d untuk Sumur MT-06. Liquid loading pada 3 kandidat sumur di Lapangan MLT diperkirakan terjadi saat tekanan reservoir mengalami penurunan seiring sumur diproduksikan dengan laju alir gas menurun dan tidak mampu mengangkat liquid ke permukaan]]>

<![CDATA[Tujuan : Dalam penelitian ini membahas mengenai variasi salinitas dan konsentrasi yang memiliki nilai optimal menggunakan metode phase behavior. Metodelogi : Pada penelitian kali ini menggunakan variasi salinitas yang beragam, yaitu 5000ppm,8000ppm,11000ppm,15000ppm dan 20000ppm. Sementara penggunaan konsentrasi sebesar 0,5%,1%,1,5% dan 2%. Langkah awal penelitian dengan membuat larutan salinitas brine dengan mencampur NaCl dengan aquadest, kemudian melakukan pembuatan konsentrasi surfaktan dengan mencampur surfaktan dengan salinitas brine. Untuk pengujian berikutnya adalah uji densitas brine dan surfaktan. Tahap berikutnya adalah pengujian aqueus stability untuk mengetahui apakah sampel surfaktan bisa masuk ketahap berikutnya dengan melihat jernih atau tidaknya. Phase behavior dapat dilakukan setelah pengujian aqueus stability. Hasil dan Pembahsan : Hasil dari aqueus stability mendapatkan hasil jernih pada semua salinitas dan konsentrasi, untuk tahap phase behavior pada salinitas 8000ppm dengan konsentrasi 2% memiliki nilai emulsi yang lebih besar dibandingan dengan sampel surfaktan yang lain. Kesimpulan : Adanya emulsi yang terjadi pada salinitas 8000ppm dengan konsentrasi surfaktan 2% membuktian bahwa semakin besar salinitas tidak menjamin emulsi akan semakin besar.]]>

<![CDATA[This research is a continuation of several previous studies that have been published, in general studying fluid flow in reservoirs. There are 2 fluid flows in reservoirs, namely linear and radial, while there are 3 types of fluids, namely incompressible, slightly compressible and compressible. In this study, the pressure and pressure drop of incompressible fluids at a certain distance from the well to the reservoir are calculated. The equation used to calculate fluid pressure is derived from the Darcy Equation. To obtain accurate data, the calculations are carried out repeatedly with 1 ft intervals, namely to get an overview of changes in pressure. The initial calculations were done manually but because the calculations were quite difficult and repetitive, the Fortran software was used to calculate them. Numerical calculations were carried out with some rock permeability data. The calculated results obtained pressure characteristics from a certain radius to the well with several values of rock permeability and these results are expressed by a graph between pressure and radius.]]>

<![CDATA[Large amounts of oil are still trapped in the microscopic pore spaces of the rock during the primary and secondary recovery processes as a result of competition between the viscous forces and the capillary forces that arise from the interfacial tension (IFT) between the oil and water phases which causes the injected water to pass through the residual oils. To recover the remaining oils, the capillary pressure between the fluids must be significantly lowered by reducing the IFTs with surfactant. The selection of the best surfactant that is suitable for reservoir fluids and rocks in harsh reservoir conditions through laboratory studies is critical before conducting a field surfactant injection. Compatibility of surfactant with reservoir conditions such as reservoir temperature, high formation water salinity and rock absorption of surfactant molecules is a major challenge in the field surfactant injection. The best surfactant should be compatible with reservoir fluids and rocks and capable of increasing the efficiency of microscopic displacement and oil recovery factor. This investigation was aimed to provide valuable information about the recovery processes of oil stripping in microscopic pore spaces of core samples by spontaneous imbibition of surfactant molecules under high reservoir temperature conditions. The spontaneous imbibition processes were conducted in Amott imbibition cells. The process of the fluids interactions and oil recovery was observed and also recorded for further analysis and calculations. The results showed that non-ionic surfactants were more stable and performed better capability in stripping and recovering oil from core samples at high reservoir temperature.]]>

<![CDATA[Indonesia is located below the equator and has high exposure to sunlight throughout the year, providing great potential for generating electrical energy from solar sources. The demand for electrical energy in Indonesia continues to increase every year, so that it is very important to take advantage of the abundant potential of solar energy to become a source of renewable energy for power generation. This study focuses on analyzing the potential and effectiveness of using solar power and the challenges in its use, especially in the Makassar area. Solar power can generate up to 112,000 GWp of electricity or the equivalent of 89,600,000 MW. One of the challenges faced in using solar panels is the high material and installation costs, as well as people's dependence on conventional electricity. The Indonesian government has set a target to obtain 23% of the total electricity capacity from renewable energy sources by 2025. One solution is to use a rooftop solar system which can directly convert solar radiation into electrical energy. The energy generated from the Rooftop PLTS system can be stored in a battery that is controlled by a regulator and used at night. The use of on-grid PLTS or Rooftop PLTS can provide the advantage of saving PLN's electricity by 39.9% to 110.5%. It can be concluded that using energy from solar panels in a month can produce carbon gas emissions by 3.3% or carbon gas emissions are reduced by up to 96.7%.]]>

<![CDATA[The inability of a reservoir to pass large amounts of fluid can be caused by very low permeability. Objective: This research aims to increase well productivity in wells that have low permeability. Based on reservoir data, the permeability in the IQ well is tight permeability, namely 0.153 mD, so that fluid in the reservoir cannot flow into the well due to the low permeability of the formation. The low permeability of the formation resulted in a low production rate of 39 BLPD. Methodology and results: in this research a stimulation acidizing method was used but this method was less than optimal (seen from the absence of a pressure drop after acid was injected at a high flow rate), so a hydraulic fracturing method was carried out on the IQ well to increase well productivity. The results of this research use the PKN (Perkins, Kern & Nordgren) fracturing model to obtain a fracture length greater than the fracture height. The fracturing fluid used as pad and slurry is YF120.HTD and the flush fracturing fluid used is 4% KCL Water. The proppant used is Carbolite 20/40. The resulting fracture geometry was 111 ft, fracture height 55 ft and fracture width 0.375 in. The conductivity value of the fracture formed was 18.1 mD with a fracture permeability of 320,177.383 mD/ft. The productivity index increased by 2,945 with a production rate of 440.14 BFPD. The total cash flow obtained was $4,858,624.11 and NVP $2,413,572.70. The capital issued will be returned within 21 days. Conclusion: based on the results above, the IQ well is suitable for hydraulic fracturing]]>

<![CDATA[Mirabelle 01 M01 well is a developed-stage well which has undergone drilling since February 2020 until May 3th 2020. It has 13000 ft depth and dominated with sandstone layers and some shaly inserts. This well is a high temperature (300 F), low permeability (0.5-5 mD) and porosity well which casues hydraulic fracturing should be done in this well. Aim: to carry out fluid fracturing design analysis by considering additional materials and economics. The perforation in this well divided into 2 perforations, first perforation has been 297 ft long and located at 12143 ft-12440 ft of well depth. The second perforation has been 45 ft in length and is located at 12,730 ft-12,685 ft of well depth. Payzone of this well is dominated by sandstone which is determined from the low gamma ray data. This Mirabelle 01 M01 well has high resistivity due to the resistivity log. Water mix used for the formation is a neutral water mix but still has several negative ions with corrosive properties such as SO42- and Cl-. Acid inhibitors are needed to remove these ions and prevent corrosive to be happened. Scale inhibitors are also needed to be added to prevent scale formation caused by Mg2+ ions which are contained in the mix water. From the average pressure calculation, the closure pressure was found about 7914.67 psi. The young modulus found from 8-10 Mpsi which indicates that the formation has high stiffness. The base of the fracturing fluid used is low price water-base fluid with guar gum polymer which can produce hydroxypropilguar (HPG) that don't ruin the formation even if the formation is in the high temperature. Borate ions are used to be crosslinker agents that binds metal ions with polymers. To split polymers molecules, sodium salt from the peroxydisulphate is used to be the gel breaker.]]>
