Abstract

Foam injection is a variance of gas flood as tertiary recovery method designed to mitigate low sweep efficiency normally found in gas flood due to inheritance of density difference between injected gas and oil which often severed by presence of reservoir heterogeneity (permeability contrast in this case). Foam EOR has two goals: (1) improve oil recovery by promoting better sweep efficiency, and (2) reduce carbon emission related to global warming issue provided that the injectant gas used is CO2, hydrocarbon gas or flue gas.. Reservoir simulation performed is able to show recovery improvement of foam compared to continuous gas injection.

Abstract

Calculation of hydrocarbon flow in the form of oil or gas in Petroleum Engineering is used the Darcy equation. Deriving the Navier Stokes equation produces a general equation that cannot be used for special conditions, for example linear or radial flow because the formulation is different. In this paper, the Darcy equation obtained through experimental evidence is derived from the Navier Stokes equation with several assumptions and simplifications . The calculation in this paper uses a numerical solution, which uses Fortran language, as one approach. Then by using field data, the Darcy equation is used in calculating the flow rate and the velocity of linear fluid in the reservoir. And also the calculation of the pressure from the well to the outermost point of the reservoir with radial fluid flow, so that the pressure gradient data can be obtained from the well to the outermost point of the reservoir.

Abstract

Increasing the level of an extract into a marketable and valuable mineral or beneficiation process can be carried out in various ways, one of which is a table technique ("Wilfley table"). Beneficiation begins with knowing the character of ore through XRD characterization, mineragraphy, SEM-EDS and Fire Assy, Then, the ore is smoothed to a range of ~ 200 mesh and concentrated with rocking table gravity by varying the size of rock fraction, table slope and water discharge. Based on the comparison of XRD characters, mineragraphy, SEM-EDS and fire Assy from the initial seeds and recovery, the results obtained is found to be within the optimum conditions at fraction ~200 mesh size, 3o  elongation table, and water discharge of 14 liters / minute and with gold recovery of 84.48% or increase gold content from 1.32 g / ton to 18.75 g / ton. Based on the optimization, the finer the size of the particles , the higher the level of gold recovery. Nevertheless, the increase in the slope of the table and water discharge can reduce the recovery of gold.

Abstract

The oil potential from low quality reservoir of Field “X” is big and current recovery is not optimum yet.  The typical low quality reservoir with low permeability characteristic is commonly not optimum if it is developed using common vertical well and horizontal well. These methods give low fluid rate deliverables that impact on low recovery and also operational challenges on artificial lift performance since not working on optimum range condition. To improve production performance and recovery, it is required the advanced method such as horizontal drilling using hydraulic multi step  fracturing.  However horizontal drilling using hydraulic multi step  fracturing method need higher capital expenditure and more complex operational aspect during execution. On the current oil price condition, it is required comprehensive investment analysis for decision analysis consideration by performing oil price and investment cost sensitivity analysis, development scenario whether it is delay option, call option or put option.  This research performs economic analysis using both Cost recovery PSC system and  Gross Split PSC system. For economic analysis method, it use conventional Discounted Cash Flow (DCF) and Real Option to understand the value of flexibility that important for decision consideration.The economic analysis of  low permeability reservoir development for 6 wells indicate that this project need 17.6 MM US$ capital expenditure, and will recover oil volume  around 1.89 MMBO. Economic evaluation using DCF method with discount rate 10.8% indicate the  economic indices for PSC Cost recovery (NPV = 6.08  MM US$, IRR= 28.9%, POT=  0.997 years, PI= 1.28 and Value Creation (VC) 10.65 MM US$) and for PSC Gross Split  (NPV = 10.64  MM $US, IRR= 29.0%, POT=  1.517 years, PI= 1.49 and value creation (VC) 1.94 MM US$). Economic analysis using  Real Option method with Black Scholes Merton  (BSM) indicate that this project will  deliver call option value around  9.8 MM US$ with value of flexibility around 3.7 MM US$ for PSC cost recovery. Meanwhile Real Option analysis for PSC gross split gives call option value around 10.7 MM US$ and value of flexibility around 4.1 MM US$.  The 2 (two) methods recommend that this project economically feasible and  suggest to execute the project as planned schedule (call to expand). According to the operational and economic assumption, it is suggested that Gross Split PSC system is potentially better on economic outcome than PSC cost recovery for the contractor (KKKS).

Abstract

Drilling operations always require fluid in their activities. Because to penetrate the soil and rocks will be very easy with the use of fluid.  The fluid will help soften the soil and rocks making it easier for the drill bit to penetrate it. Drilling fluid is also needed to attach the casing to the drill wall. So that the wall does not collapse, as media logging and so on. Of course, each drilling zone (surface zone, intermediate zone, and production zone) has different characteristics and different additive substances are needed. This study wants to find out the function of the use of calcium chloride additives on the nature of cement hardness and choking time. This research is important because it will be known this addictive nature as a retarder or accelerator. By knowing the nature of this additive so that it can be used in the right zone. Testing on Calcium Chloride additive for the value of compressive strength is very effective at a concentration of 8%, 24-hour immersion time and a temperature of 150 ° F with a test result of 4483 psi. Whereas, at temperatures of 80 ° F and 100 ° F, the maximum value of compressive strength for Calcium Chloride additive occurs at a concentration of 10% with a test result of 2393 psi and 2888 psi. Based on the data presented, temperature plays an important role in testing the thickening time of a cement sample. The addition of calcium chloride additive functions as an accelerator.

Abstract

Fisika adalah suatu ilmu yang mempelajari tentang alam semesta, baik mempelajari partikel yang berukuran kecil sampai dengan planet yang berukuran makro. Bidang kajiannyapun beragam dari mempelajari struktur bumi sampai dengan sistem tata surya. Salah satu penerapan ilmu fisika adalah di bidang industri perminyakan. Perkembangan teknologi perminyakan dewasa ini sangat pesat sekali, salah satunya adalah dalam pengeboran atau drilling. Operasi pemboran tidak pernah lepas atau mengabaikan penggunaan fluida pemboran. Fluida pemboran terdiri dari dua pekerjaan yakni rekayasa lumpur pemboran dan penyemenan.Penyemenan diperlukan supaya dapat mengurangi permasalahan sewaktu melakukan pemboran pada trayek selanjutnya. Tingkat keberhasilan penyemenan ditentukan oleh 2 hal yakni kualitas bahan penyemenan yang terdiri dari bahan dasar semen serta aditif dan teknik pelaksanaan penyemenan. Pada penambahan Sodium Lignosulfonate terjadi penurunan nilai compressive strength  dan menaikan nilai thickening time pada konsentrasi 1% adalah 255 menit dengan temperatur 80°F karena pada dasarnya additive ini bersifat retarder. Pengujian additive Calcium Chloride untuk nilai compressive strength sangat efektif pada konsentrasi 7% dengan hasil test 4483 psi pada temperatur 150°F, sedangkan pada temperatur 80°F dan 100°F hasil test yang didapat sebesar 2393 psi dan 2888 psi, sedangkan nilai thickening time menurun dikarenakan sifat additive ini sebagai accelerator.

Abstract

Thin Bed Identification is still a difficult task even with the advanced technology of seismic acquisition. Certain high frequency component is necessary and could be obtained through resolution enhancement. Short – Time Fourier Transform Half Cepstrum (STFTHC) is performed to enhance seismic resolution thus a better separation of thin bed could be improved. Basic principal of STFTHC is to replace the frequency spectrum by its logarithm while phase spectrum remains the same. Synthetic seismic was built based on Ricker and Rayleigh criterion. They were used to test the program yielding a better separation of two interfaces under tuning thickness without creating new artifacts. The algorithm was applied to seismic data from TG field. Using post-STFTHC seismic data as input of acoustic impedance inversion, well tie correlation increases by 10% and decreases inversion analysis error by 17,5%. Several thin bed -which once could not- could be identified on acoustic impedance result.

Abstract

Salah satu problema dalam kegiatan produksi sumur minyak adalah ikut terproduksinya air formasi bersama-sama dengan minyak. Sumur J-001 yang diteliti dalam makalah ini mulai berproduksi sejak Maret 2015 dengan produksi awal 1144 bfpd/1138/bopd/WC 0.52%. Produksi minyak terus mengalami penurunan seiring dengan peningkatan water cut yang mencapai hingga 98%. Untuk mendiagnostik permasalahan yang terjadi dilakukan plot diagnostik Chan. Plot diagnostik Chan merupakan plot Water Oil Ratio dan Water Oil Ratio derivatif terhadap waktu untuk mengetahui adanya peningkatan produksi air yang tidak normal. Berdasarkan plot Chan terdapat indikasi bahwa sumur ini mengalami water channeling berupa near borehole channeling, dan berdasarkan data log petrofisika dan log CBL diputuskan untuk melakukan remedial cementing pada interval zona target dan di antara zona target dan zona air. Berdasarkan indikator nilai amplitudo, variable density log, dan transit time, remedial cementing pada Sumur J-001 berhasil memperbaiki ikatan semen baik di zona target maupun di zona sekat air. Grafik kinerja produksi setelah remedial cementing menunjukkan adanya penurunan water cut dari 98% menjadi 87-90%. Produksi minyak mengalami kenaikan dari 3 bopd menjadi rata-rata 144 bopd. Plot diagnostik Chan Sumur J-001 setelah remedial menunjukkan nilai WOR dan WOR’ yang stabil sehingga dapat disimpulkan bahwa near borehole channeling yang terjadi pada Sumur J-001 dapat tertangani dengan baik.
