Water injection is a conventional method which increases the recovery percentage by providing pressure support and displacing oil in the heterogeneous porous medium. In such a displacement process, (low) mobility ratio is important for a more efficient oil displacement by the injected fluid. As such, the mobility ratio can be reduced using the fluids involving gelling agents for increasing in the volumetric sweep. While polymers degrade and break up on experiencing sudden shear stresses and high temperatures, polymer macromolecules are forced to flow into narrow channels and pores where molecular scission processes can take place. Thus, it is of utmost importance to have a strong understanding of the use of the right type and amount of viscosity as a reduction agent. For polymer injection, a comparison of xanthan polymer and synthetic polymer mechanisms was conducted. A commercial full-physics reservoir simulator was coupled with a robust optimization and uncertainty tool to run the model, where a simplified gel kinetics was assumed to form a microgel with no redox catalyst. Water injection continues over all six layers for 450 days, followed by gel system injection for 150 days in the bottom two layers. Water injection was continued to four years. The top four layers have higher horizontal permeabilities, and a high permeability streak is at the bottom of the reservoir to reduce any helpful effects of gravity. Control and uncertainty variables were set to investigate the sensitivity of this process using the coupled optimization and uncertainty tool. Results demonstrate deep penetration of gel and blocking of the high permeability bottom layers. Sensitivity studies indicate the relative merits of biopolymer, xanthan polymer in terms of viscosity effects vs synthetic PAM in terms of resistance factor vs in-situ gelation treatments and their crossflow dependence. Adsorption and retention of polymer and gel are permeability dependent. Considering the potential for application of gel solutions in the U.S. and throughout the world, this study illustrates the relative advantages of different treatments in terms of viscosity reduction in the same model in a comparative way, while outlining the significance of each control and uncertainty variable for better management of reservoirs where displacement efficiency is highly critical.

The declining reservoir, oil production and pressure depletion with the well being produced, the results of the investment of the well will also decrease. For that there needs to be energy that can help to lift the fluid to the surface. One of the artificial lift methods that can be used is a gas lift. Gas lift is a method commonly used when there is a natural gas source as an injection gas supply. The selection of the artificial lift method is based on several considerations, namely the reservoir conditions, fluid conditions, well conditions, conditions on the surface, availability of electricity, availability of gas, and sand problem. The influential parameters in the selection of gas lifts include: Productivity Index (PI), Gas Liquid Ratio (GLR), depth of the well and driving mechanism from the reservoir. The Gas Lift that the production optimization wants to do is the injection system in a Continuous Gas Lift. Used in wells that have a high Productifity Index value. Where in the LB field to be analyzed, the Productifity Index value is 2.0 bpd / psi. This study intends to optimize a gaslift well performance as an effort to maximize the results of well production. Based on the research that has been done using Prosper Modeling on the “J” field, the following conclusions are obtained the effect of pressure and viscosity on the gas lift well flow rate in this condition can be said to be efficient, because the conditions / pressure given at temperatures below 300 F can reach the miscible condition and from the results of determining the optimal conditions to get the best well performance, obtain an optimal liquid rate of 1829.4 STB / D with an oil rate of 36.6 STB / D.   Keywords: Gas lift, Optimization, Immiscible Pressure, Viscosity

Waterflood introduces in the oil field a couple of years ago. Several waterflood schemes have been implemented in the fields to get the best incremental oil, such as peripheral injection, pattern waterflood, and etcetera. Many waterflood schemes are not working properly to boost the oil recovery due to unpredicted and unexpected water tide array. Then, the tracer practice started to be used for getting a better picture of the transmissibility reservoir as well as the direction of water pathway. This practice honors the parameters, such pressure, water cut, GOR, and rates. The streamline modeling is used to map the tracer, and it concludes that the selection of location of the injector should be based on the highest oil recovery achieved. Subsequently, the cyclic water injection method is one alternative. Apparently, this approach yields a quantify incremental recovery. This research utilizes the pressure different approach to figure out the route of water in the formation. The inter-well tracer technique in this modeling study is a tool to review communication between injectors and producers in the existing pattern. Many scenario should be tried to find the best options for the new pattern opportunities. In parallel, a innovative scheme of waterflood technique should be implemented too for escalating oil recovery. The stream pathway observes a new potential of the waterflood scheme. It is called "cyclic injection" scheme. The novelty of this approach is the ability to solve the poor sweep efficiency due to improper pathway of water influx in the oil bearing".

This study aims to determine the benefits of the interwell tracer test technique in improving the streamline simulation on the existing array's re-look. It also analyses the best scheme for the injection spot to enhance oil recovery. This study's subject parameters are limited to the tracer's breakthrough time, produced concentration, cumulative production, and pathline movement. The results showed that previous studies distinguished the correlation between injectors and producers with the development of a new pathline that conveys a scheme of water-flood for the application. Furthermore, several developments of water-flood schemes have been executed for better oil recovery in the mature fields worldwide. The vigorous simulation model is an effort to imitate the actual field capable of enhancing the character's understanding and helping the waterflood to rinse the oil trap or the unswept pocket. Unlike a Cartesian model, the streamline conveys an enhanced portrait of the transmissibility reservoir in terms of pressure-driven. The streamline model suggests the injector's preferred position to unlock any unswept oil in the formation and minimize the water path conflict, which leads to over injection in some regions. The expected outcome is the ultimate oil increment with the original technique associated with re-patterning the wells appropriately to gain residual oil saturation in the virgin alleyway.

The condition of a well if it is produced continuously will cause reservoir pressure to fall, and the flow rate will also go down, as a result the productivity of the well will also decrease. For this reason, there is a need for energy that can help lift fluid up to the surface. In the primary method there are 2 stages of production, namely natural flow where oil is raised directly through the tubing surface, and artificial lift is the method of obtaining oil by using the aid of additional tools. In the oil industry there are various types of artificial lifts, one of which is an electric submersible pump (ESP). Electric Submersible Pump is an electric pump that is immersed into a liquid. This pump is made on the basis of a multilevel centrifugal pump where each level has an impeller and iffuser which aims to push the fluid to the surface. ESP planning is strongly influenced by the roductivity of production wells. The rate of fluid production influences the selection of pump type and size. This is because each pump has its own production rate based on the type and size of each pump used. In the course of producing oil, there will certainly be a problem that will cause a decline in production, therefore it is necessary to evaluate and redesign the ESP pump, in an effort to optimize the production potential of these wells. In this study an evaluation of the performance of the electrical submersible pump will be carried out and a pump redesigned to optimize production using AutographPC software on the well X in the field Y Kondisi suatu sumur jika diproduksikan terus-menerus akan mengakibatkan tekananreservoir turun, dan laju alir akan turun pula, akibatnya produktivitas sumur akan turunjuga. Untuk itu perlu adanya tenaga yang dapat membantu mengangkat fluida sampaikepermukaan. Dalam metode primer terdapat 2 tahapan produksi yaitu natural flowdimana minyak terangkat kepermukaan langsung melalu tubing, dan artificial liftmerupakan metode perolehan minyak dengan menggunakan bantuan alat tambahan.Dalam dunia perminyakan ada berbagai macam jenis pengangkatan buatan salahsatunya adalah electric submersible pump (ESP). Electric Submersibel Pump merupakan pompa listrik yang dibenamkan kedalam cairan.Pompa ini dibuat atas dasar pompa sentrifugal bertingkat banyak dimana setiap tingkatmempunyai impeller dan diffuser yang bertujuan untuk mendorong fluida kepermukaan.Perencanaan ESP sangat dipengaruhi oleh produktivitas sumur produksi. Laju produksifluida berpengaruh terhadap pemilihan jenis dan ukuran pompa. Hal ini dikarenakantiap-tiap pompa memiliki laju produksi sendiri berdasarkan jenis dan ukuran tiap- tiappompa yang dipakai. Dalam kegiatan memproduksikan minyak tentu suatu saat akan terjadi permasalahanyang mengakibatkan menurunnya produksi, Oleh karena itu perlu dilaksanakan evaluasidan design ulang pompa ESP, sebagai upaya untuk mengoptimalkan potensi produksisumur-sumur tersebut. Pada penelitian ini akan dilakukan evaluasi kinerja electricalsubmersible pump dan melakukan desain ulang pompa untuk optimasi produksidengan menggunakan software AutographPC pada sumur X lapangan y Kata kunci: electric submersible pump, AutographPC, laju produksi

Indonesia has proven oil reserves of around 3.7 million barrels but production has been declining unwittingly over the last decade as companies rely solely on the Old Oil Field. PT. SPR Langgak is one of the companies that own the Old Oil Field so it is necessary to develop it to increase production in the Dandelion Field. One of them is the surfactant huff and puff method. However, because surfactants are expensive and this work depends on the economy and oil prices, there need to be more attractive investment options. There is a new investment option prepared by the Government, namely the Gross Split PSC cooperation contract based on Ministerial Regulation no. 52/2017. This study aims to analyze the economic feasibility of Huff and Puff Surfactant Injection using the gross split contract. From the calculation results, the Huff and Puff Surfactant Injection Project at the Dandelion Field is economically feasible to do because it has a large and positive NPV value (NPV = 7,862 M US$, an IRR value greater than the MARR 15% (IRR = 214% and POT value are less than the project life or faster (POT = 1.62 months). Based on the sensitivity analysis, the huff & puff surfactant injection job will be more profitable if the oil price and large oil production. On the other hand, the operating cost is better if the value is small. The lowest limit for oil prices is 28.1 US$/bbl.

Penggunaan hybrid-alkali mampu menangani masalah adsorpsi surfaktan pada formasi menjadi jauh lebih rendah, mengurangi biaya logistik, dan mampu meningkatkan perolehan minyak (Oil Recovery). Hybrid-alkali yang akan digunakan pada penelitian ini adalah Natrium Karbonat (Na2CO3) dan Amonium Hidroksida (NH4OH) yang mudah didapatkan dan lebih ekonomis dibandingkan alkali lainnya. Penelitian ini menggunakan simulator Computer Modeling Group (CMG) GEM 2020. Pemodelan menggunakan batuan karbonat yang dilakukan pada reservoir heterogen dengan distribusi permeabilitas memiliki nilai 100 mD hingga 300 mD. Pemodelan memiliki ukuran grid 5 x 1 x 10, dengan total volume pori 1,203 x 107 ft3. Reservoirnya terletak pada kedalaman 1900 ft sampai 2060 ft. Adapun komponen fl uida injeksi adalah alkali Na2CO3 dengan berat molekul 105,98 g/mol dan densitas 2,54 gr/cm3 sementara alkali NH4OH memiliki berat molekul 17,03 g/mol dan densitas 0,68 gr/cm3. Surfaktan Heavy Alkylbenzene Sulfonate (HABS) memiliki berat molekul 543 gr/mol dan densitas 3,79 gr/cm3, untuk polimer Hydrolyzed Polyacrylamide (HPAM) yaitu berat molekul 9000 gr/mol dan densitas 1,302 gr/cm3. Simulator CMG GEM 2020 pada penelitian ini digunakan untuk mensimulasikan dengan model Multi-Ion Exchange (MIE). Durasi data yang digunakan untuk pemodelan injeksi hybrid-alkali pada alkali-surfaktan-polimer (ASP) adalah dengan rentang waktu 2 tahun. Penelitian ini menerapkan investigasi pada hybrid-alkali untuk mengetahui pergerakan ion-ion yang mengikat minyak mentah. Berdasarkan hasil analisis secara kualitatif didapatkan bahwa fl uida mampu memenuhi seluruh grid sehingga dapat mengalir dari sumur injeksi hingga sumur produksi yaitu dengan cara mengoptimalkan tekanan injeksi. Hal itu terbukti dengan grafi k pergerakan ion Na+ dan NH4+ yang meningkat setelah diinjeksikannya hybrid-alkali. Berbeda dengan ion SO42- yang mengalami adsorpsi sehingga mengalami penurunan selama proses injeksi.

Saturasi minyak residual secara kuantitatif dapat ditentukan dengan metode logging dan coring akan tetapi metode tersebut mempunyai keterbatasan radius investigasi yang kecil. Oleh karena itu, metode Single Well Tracer Test (SWTT) menjadi alternatif yang lebih baik karena memiliki radius investigasi 10-30 ft dari lubang sumur. Namun pengukuran Sor dengan metode SWTT menjadi tidak efektif apabila parameter yang digunakan tidak optimal sehingga menimbulkan keliruan dalam interpretasi. Observasi parameter untuk mengetahui pengaruh hasil pengukuran hasil Sor terhadap konsetrasi chemical tracer pada SWTT perlu dilakukan. Konsentrasi MeOH pada overflush serta shut-in time digunakan sebagai acuan untuk mengetahui efektivitas injeksi surfaktan, yaitu perubahan Sor sebelum dan setelah injeksi surfaktan. Prinsip SWTT adalah menginjeksikan Ethyl Acetate (EtAc) ke dalam lubang sumur, kemudian berdasarkan reaksi hidrolisis antara EtAc dan H2O menghasilkan produk berupa Ethyl Alkohol (EtOH) sebagai secondary tracer. Reaksi ini terjadi hingga titik kesetimbangan. EtAc Yang tersisa akan larut di dalam minyak dan tidak dapat larut di dalam air sedangkan EtOH akan larut di dalam air. Akibatnya EtOH akan lebih mudah bergerak daripada EtAc sehingga kumulatif produksi EtAc dan EtOH pada peak concectration berbeda (retardation factor). Perbedaan ini menjadi indikator pengukuran Sor apabila +semakin besar retardation factor maka semakin besar pula Sor yang didapatkan. Begitupun sebaliknya, apabila retardation factor kecil maka Sor juga akan kecil. Simulator STARS merupakan produk yang dikeluarkan oleh Computer Modeling Group (CMG), pemodelan dapat mencakup multicomponent, multiphase, chemical flooding, chemical reaction model dan single well tracer test, simulator ini dapat mengetahui tingkah laku fluida reservoir pada media berpori yang homogen maupun heterogen. Setelah dilakukan analisis yang mengacu pada kurva permeabilitas relatif, maka skenario 1 case 10 merupakan skenario terbaik karena didapatkan kan Sor 0,4. Adapun parameter yang digunakan adalah konsentrasi EtAc , 0,0025 mole fraction, MeOH 0,011 mole fraction dan shut in time 2,5 hari. Setelah injeksi surfaktan diperoleh Sor 0,26. Ini berarti terjadi perubahan 14% Sor menurun setelah injeksi surfaktan yang membuktikan kesuksesan metode SWTT dalam memonitor efektivitas injeksi surfaktan. berdasarkan peak concentration EtAc diikuti oleh penurunan Sor. sebaliknya penurunan konsentrasi EtOH diikuti oleh kenaikan Sw.
