<![CDATA[Meningkatnya water cut pada sumur MY05 menyebabkan terjadinya penurunan produksi minyak. Untuk mengatasi masalah tersebut, perlu dilakukan pekerjaan squeeze off pada zona perforasi yang mempunyai kontribusi produksi minyak yang rendah dan potensi produksi air yang tinggi. Setelah pekerjaan squeeze off selesai, selanjut dapat dilakukan pekerjaan shot top perforation (STP) untuk membuka zona produksi supaya produksi minyak dapat produksi. Pemilihan lapisan sand 1440’ sebagai target perkerjaan squeeze off dan STP berdasarkan jumlah cadangan minyak yang tersisa (remaining oil reserve). Selain itu studi keekonomian juga dilakukan untuk mengetahui tingkat kelayakan proyek. Hasil kedua pekerjaan tersebut mengindikasikan adanya peningkatan produksi minyak sebesar 405 BOPD dan berkurang nya nilai water cut menjadi 76%. Hasil analisa keekonomian menunjukkan bahwa pekerjaan tersebut sangat ekonomis untuk dilakukan.]]>

<![CDATA[Pemanfaatan minyak bumi yang tidak memperhatikan kelestarian lingkungan akan merugikan manusia dan mengakibatkan pencemaran lingkungan, sehingga perlu dilakukan penanggulangan melalui pengelolaan dan pemanfaatan limbah dengan cara bioremediasi. Bioremediasi merupakan suatu proses pemulihan lahan yang tercemar dengan mengeksploitasi kemampuan mikroorganisme untuk mendegradasi senyawa-senyawa organik. Pemilihan mikroorganisme bioremediasi sangat berpengaruh terhadap proses degradasi minyak bumi. Hal tersebut dikarenakan setiap spesies mikroorganisme membutuhkan substrat yang spesifik untuk mendegradasi keseluruhan komponen penyusun minyak bumi. Perlu pendekatan lebih lanjut untuk mengetahui efektifitas metode bioremediasi dan mikroorganisme yang digunakan baik mikroorganisme yang diperoleh dari luar (nonindigenous) atau mikroorganisme lokal (indigenous) yang digunakan para peneliti dalam mendegradasi minyak bumi. Namun, tidak semua rangkuman jurnal yang ada menunjukkan informasi yang detail mengenai metode dan efektifitas mikroorganisme dalam bioremediasi. Dalam paper ini, akan dikaji beberapa metode dan mikroorganisme yang digunakan dalam bioremediasi, diantaranya biopile, bulking agent,ex-situ, konsorsium bakteri dan teknik land treatment sehingga dapat disimpulkan metode paling efektif dalam bioremediasi minyak bumi.]]>

<![CDATA[Area X merupakan bagian dari lapangan Y saat ini mengalami dalam kurun waktu 16 tahun terakhir penurunan laju alir produksi sebesar 64.4%. Diperlukan upaya untuk meningkat laju alir produksi minyak dan recovery factor dari area tersebut, upaya yang akan dilakukan adalah injeksi air atau waterflood dengan mengubah salah satu sumur produksi menjadi sumur injeksi (convert to injection). Penentuan kandidat sumur convert to injection (CTI) berdasarkan kondisi laju alir produksi, jarak antara sumur kandidat dan sumur produksi, serta korelasi antar sumur. Untuk memperoleh hasil yang optimal akan dibuat beberapa skenario yang akan disimulasikan dengan parameter rate injeksi dan penambahan perforasi. Penentuan rate injeksi dilakukan dengan uji sensitivitas terlebih dahulu dan memperhatikan tekanan fracture dari tiap lapisan. Penambahan perforasi dengan melihat korelasi dari data log yang ada sehingga sumur CTI dapat memberikan peningkatan terhadap sumur produksi. Hasil simulasi yang paling optimal dari skenario yang direncanakan diperoleh penambahan produksi sebesar 800 MSTB dan recovery factor sebesar 12.9%.]]>

<![CDATA[Water content in natural gas poses threat to process facilities such as column distillation. Natural gas from reservoirs usually contains water vapor, the presence of water vapor in gas processing causes bad impact to process facilities. Dry Gas composition data was taken from Salamander Energy. Optimization of natural gas dehydration using Tri Ethylene Glycol was carried out using Aspen HYSYS V8.6 with Peng-Robinson fluid package. The natural gas dehydrating plant was designed with operating conditions of 394 bar and 460C and 10 MMSCFD and 6.8 MMSCFD gas flow rate were inputted. Results obtained from HYSYS simulation shows. Three different TEG flowrates were used for this simulation. Results obtained from simulation that . For the purpose of running the plant economically, the minimum flow rate of TEG which will reduce the water content to within the limit of pipeline specification, is very important and the result obtained showed that a minimum of 3 m3/h of TEG is required to reduce the water content of a gas stream of 10MMSCFD to 6.8lb/MMSCFD, which is within the limit of 6-7lb/MMSCFD, this value when compare to gas plant which uses 15m3/h for the gas stream of 10MMSCFD to achieve the same water content specification is far lower. Values below this flow rate (3.5m3/h) may not reduce the water content to the specified limit.]]>

<![CDATA[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.]]>

<![CDATA[Field SS is a Heavy Oil field which means high viscosity oil making it difficult to flow. Therefore, artificial lift was used in this field to help lifting the high viscosity fluid, i.e. sucker rod pump (SRP). In the last several years, problem of the damage to the rod string was frequently occur. Rod string damage is usually indicated by the occurrence of broken or detached components. In order to overcome the damage of rod string components on the sucker rod pump, several parameters that causes rod string damage in 41 well samples in the field SS were analyzed and then recommendations were made as an alternative to minimize the occurrence of rod string damage. After analyzing the parameters that can cause rod string damage on 41 well samples in SS field, the cause of the breakdown of rod string is fluid pounding for 37 samples well, while the causes for 4 samples of other wells is not detected. After that, recommendation efforts is done, like size down pump speed and stroke length for 9 samples of wells, size down pump size and pump speed for 6 samples of wells and size down pump speed for 22 samples well. As for the undetected cause 4 samples of wells, is recommended to do proactive well service.]]>

<![CDATA[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.

<![CDATA[Characterizing heptanes plus fraction in PVT analysis has been a complex problem since its first inception. In this publication, the author is reviewing available mathematical functions employed for this task, whilst pointing out advantages and weaknesses for each of them and proposing a new method that is capable of complex characterization.
This publication addresses a new method that is capable of accurately characterize heptane plus fraction especially in discontinued areas where errors could leap up to 40%. The author modifies natural logarithmic function to be used as an accommodation to discontinuities. The modified distribution provides better accuracy in modeling the discontinuities as a straight-line function, making them ideal for real gas condensate composition characterization. The new method is tested against several test data used by previous researchers, and applied to 3 sets of field data. The results have shown that this new method is capable of lowering CPU requirement whilst making better accuracy for all test data.]]>

<![CDATA[Low salinity waterflooding (LSW) is categorized as one of emerging EOR technologies. It is done by injecting water with different salt composition and/or concentration. The research has been carried out for both sandstone and carbonate with the results looks promising. However, most of this research still concentrated in the north sea, middle east and North America region. This article discusses the applicability of low salinity waterflooding methodology in Indonesia. Spontaneous imbibition test is carried out to observe the recovery gain from a various combination of concentration and composition of the injected brine. The change of pH of the brine is also examined in order to confirm the pH effect mechanism. Three different concentration of brine (500 ppm, 5.000 ppm, and 10.000 ppm), three different brine composition (NaCl, CaCl2, and MgCl2) and high paraffinic crude oil are used as the fluid sample. It is found that the increased oil recovery is significant at a salinity of 10,000 ppm for MgCl2 and 5,000 ppm for NaCl ions. While the lowest recovery was shown by the test at a salinity of 500 ppm]]>

<![CDATA[In oil and gas drilling activities, drilling mud is one of the most important commodities. The main mineral used as a reactive solid that works to suck fresh water and form drilling mud is bentonite. Bentonite which is used as a drilling mud in the market is mostly imported from the United States. In Indonesia there are several areas that have enough potential for bentonite minerals, namely Java, Sumatra, parts of Kalimantan and Sulawesi with reserves estimated to be more than 380 million tons. (Riyanto A, 1994). This study uses bentonite in Kulim area, Tenayan Raya City, Pekanbaru, in hopes of providing useful information input, especially in the use of bentonite minerals in drilling mud. Using local bentonite the price is cheaper and more efficient.
The object observed was the effect and number of bentonite mixed with fresh water so that the rheological properties of drilling mud such as viscosity, gel strength, mud cake and filtration loss were obtained and would be in accordance with API specification 13A standards. Whereas to find out the composition and structure of local mineral clay, SEM and EDX analyzes were performed to determine the characteristics and composition of these minerals. From these tests add additives NaCO3 and NaOH as ion exchangers and add the element Na to the sludge.
From SEM and EDX analysis, two samples taken in central Sumatra Sumatra can be categorized as clay Illite fe-rich and Clay Illite Platty. Rheological testing of drilling mud and chemical composition analysis of clay Illite fe-rich minerals and Clay Illite Platty in Riau, Central Sumatra and with the addition of additives NaCO3 and NaOH to local Clay, Rheology in mud based on Clay Illite Platty is obtained with Bentonite. commonly used as a basic material for the manufacture of oil and gas drilling mud with API Spec13 A.]]>
