Aplikasi Tryout Ujian Online untuk SMA/SMK Sederajat
Authors: Kumalasari Ellisia , Erika E , Mustikasari Dyah
Published: March 2018

Ujian merupakan salah satu bentuk evaluasi yang diadakan setelah proses belajar mengajar berlangsung. Banyaknya kelulusan dari suatu sekolah, mencerminkan kemajuan serta keberhasilan di sekolah tersebut. Data kelulusan di kabupaten Ponorogo tahun ajaran 2015/2016 untuk SMK adalah 5.033 untuk siswa laki – laki dan 1.989 untuk siswa perempuan. Pada saat itu Ujian Nasional sudah mulai berbasis computer,  sedangkan sekolah yang melaksanakan ujian nasional berbasis komputer hanya 8 sekolah dari 38 SMK dan 4 dari 28 SMA yang ada. Data tersebut menunjukkan bahwa masih diperlukan adanya perbaikan untuk meningkatkan kualitas pendidikan. Pada awalnya, ketika siswa melaksanakan ujian nasional menggunakan naskah tertulis, siswa masih merasakan kesulitan. Mulai dari saat menjawab soal, melingkari jawaban pada lembar jawab yang apabila salah melingkari dapat berakibat fatal pada hasil ujian yang diperoleh. Sehingga diberlakukan suatu program tryout yang digunakan sebagai sarana latihan siswa dalam menghadapi ujian nasional. Selain itu, ujian yang dilaksanakan secara tertulis dapat menimbulkan kerawanan kebocoran soal. Berdasarkan permasalahan di atas, maka pemerintah mencanangkan penggunaan Ujian Nasional Berbasis Komputer (UNBK).Pemerintah memberlakukan UNBK sejak tahun 2014, namun untuk wilayah Ponorogo UNBK baru terlaksana pada tahun ajaran 2015/2016, dan hanya 8 sekolah dari 38 SMK yang menggunaan ujian nasional berbasis komputer. Dalam rangka persiapan menghadapi sistem ujian yang dilaksanakan secara online, maka diperlukan program tryout ujian secara online agar siswa tidak kesulitan dan kebingungan dalam menghadapi ujian nasional yang dilaksanakan dengan sistem online mendatang. Kegiatan pengabdian ini bertujuan untuk memudahkan siswa dalam berlatih dalam mengerjakan soal ujian berbasis komputer. Berdasarkan hal tersebut maka SMKN 1 Slahung nantinya akan dijadikan sebagai percontohan dalam  program ini. Meskipun SMKN 1 Badegan telah melaksanakan ujian nasional berbasis komputer, namun belum sepenuhnya berjalan sesuai dengan harapan karena masih kurangnya persiapan untuk melakasanakan UNBK. Metode pelaksanaan kegiatan pengabdian aplikasi tryout ujian online untuk SMA/SMK sederajat meliputi 5 tahap yaitu Analysis (analisis), Design (perencanaan), Development (produksi), Implementation (implementasi), Evaluation (evaluasi). Hasil kegiatan pengabdian IbM ini berupa (1) Aplikasi Tryout ujian online (2) Manual book untuk ditujukan untuk semua pengguna aplikasi, baik guru, siswa, maupun admin aplikasi.

A tudatos fogyasztás megjelenési formái
Authors: Csapóné Riskó Tünde , Péntek Ádám
Published: March 2018

A globalizációval és hatásaival gyakorlatilag nap, mint nap találkozhatunk. Egyik eredményeképpen olyan termékeket is vásárolhatunk, amelyek tőlünk sok ezer kilométer távolságra kerülnek előállításra. Nem mindig egyértelmű a fogyasztók számára, hogy hol, hogyan, ki által kerülnek egyes termékek előállításra. A tudatos, felelős fogyasztók számára nagy segítséget jelentenek a termékek csomagolásán elhelyezett információk, címkék, védjegyek, piktogramok a rendelkezésre álló termékek végtelen sokaságában való eligazodásban. Természetesen még számtalan egyéb módja is van a tájékozódásnak. A fogyasztóknak fontos szempont a termék származási helye, a gyártó, a gyártási folyamat, az összetevők, a gyártási folyamat társadalmi, környezeti hatásai, valamint annak etikai vonatkozásai is. A tudatos, felelős fogyasztók száma országonként különböző mértékben és arányban, de folyamatosan növekszik. A gyártók is kezdenek egyre jobban odafigyelni rájuk, próbálnak megfelelni a részükről megjelenő és erősödő elvárásoknak. Számos kutató foglalkozik a tudatos, felelős fogyasztás megnyilvánulási módjaival, hátterével, szempontjaival és motivációival. Szekunder források elemzése után primer kutatásunkkal összefüggéseket kerestünk egyes vásárlási döntéseket befolyásoló szempontok és demográfiai változók között. Az életkorra vonatkozóan egyik vizsgált korcsoportnál sem találtunk szignifikáns eltérést a vizsgált szempontok vonatkozásában. Iskolai végzettségre vonatkozóan találtunk szignifikáns eltérést az ár, gyártó, az előállítás helye, a termék összetétele és megjelenése szerint is. A családi állapottal kapcsolatban sokkal kevesebb megállapítás szűrhető le. A vizsgált tíz szempont közül a termék előállítási helyére és a lejárati időre vonatkozóan találtunk csak szignifikáns eltérést. A válaszadók jogi helyzetének elemzésekor a termék árával, megjelenésével, és ár-érték aránnyal összefüggésben találtunk szignifikáns eltérést. Utolsó vizsgált feltételünk a család jövedelmi helyzetével volt kapcsolatos. Egyértelműen kimutatható, hogy a jövedelmi helyzet romlásával egyre fontosabb szempont a termék ára.
A reklámok hatása a gyermekek vásárlási szokásaira
Authors: Gál Tímea , Hankó Fruzsina
Published: March 2018

Összefoglalva megállapítható, hogy a reklám részese az életünknek, a mindennapjainknak, ha akarjuk, ha nem, szinte lehetetlen elkerülni. A reklámoknak a gyermekek vannak a leginkább kitéve, minél kisebbek, annál inkább célpontjaivá válnak. A reklámoknak számos káros hatása lehet a szellemi és a fizikai fejlődésükre egyaránt, emellett a vásárlási szokásaikat is nagymértékben befolyásolja, ezért nagyon fontos, hogy a szülők odafigyeljenek arra, hogyan töltik szabadidejüket és a tévézés minőségi időtöltéssé váljon számukra. A legjobb az lenne, ha minden szülő részt venne gyermeke szabadidejének megszervezésében, hogy azt hasznos programokkal, játékokkal, sporttal töltse. Ez persze nem egyenlő azzal, hogy a gyermek nem nézhet televíziót, hiszen ez elkerülhetetlen, csupán csökkenteni kell azt az időt, amit a tévé előtt tölt, s lehetőleg megválogatni a műsorokat, amelyeket néz. Ugyanis kis mennyiségben a televízió és reklámok is akár hasznosnak is lehetnek számukra, ha megértik és tudatosan nézik.
A cukrászipari termékek fogyasztási szokásainak főbb jellemzői Magyarországon
Authors: Ladányi Krisztina , Szőllősi László
Published: March 2018

A tanulmány középpontjában a kézműves cukrászipari termékek fogyasztási és vásárlási szokásai állnak. A téma aktualitását adja, hogy a hazai kézműves cukrásziparban az elmúlt évtizedekben számos változás ment végbe, az ágazat belső problémákkal küzd, továbbá a megváltozott fogyasztói szokásokra is próbál reagálni, valamint a különleges magyar cukrász ágazatot – a rendelkezésre álló szakirodalmak szerint – még nem vizsgálták korábban. Célkitűzésünk megvizsgálni a megváltozott fogyasztói szokásokat és azt befolyásoló tényezőket Magyarországon. Primer kutatási módszerként a megkérdezés személyes és online formáját alkalmaztuk. Előbbi jelenleg is folyamatban van, ezért ebben a tanulmányban csak az internetes kérdőívek (n=468) eredményeit értékeltük ki. Vizsgálataink alapján kijelenthetjük, hogy a megkérdezettek többsége fogyaszt és vásárol is cukrászipari termékeket. Legtöbben a minőségi termékeket keresik és ennek érdekében akár több pénzt is hajlandóak áldozni. A fogyasztók leginkább cukrászdákban szerzik be a termékeket és a kikapcsolódás, feltöltődés, valamint a magasabb minőségű termékek beszerzése érdekében látogatják ezeket az üzleteket. A megváltozott fogyasztási szokásoknak köszönhetően a könnyedebb, természetes alapanyagú termékek a leggyakrabban keresettek.
Az étkezési tojás fogyasztási szokásainak főbb jellemzői Magyarországon
Authors: Kertész-Molnár Szilvia , Szőllősi László
Published: March 2018

Hazánkban az elmúlt években számos változás ment végbe a tojáságazatban, a vertikum szereplőinek számos kihívással kell szembenéznie napjainkban is. Magyarországon jelentősen visszaesett a tojás termelése és annak fogyasztása. A tanulmány célja megvizsgálni, hogy mely tényezők mennyire fontosak a hazai fogyasztók számára az étkezési tojás vásárlása és fogyasztása során, illetve hogy mennyire informáltak a fogyasztók a tojással kapcsolatban. Ennek felméréséhez egy online megkérdezést végeztünk, melynek során 729 értékelhető kérdőívet gyűjtöttünk be. A válaszadók 99%-a alkalmanként vagy rendszeren fogyaszt tojást, míg 79,1%-a meg is vásárolja azt. Az eredmények alapján megállapítható, hogy a hazai fogyasztók a tojás frissességét és annak sérülésmentességét tartják a legfontosabbnak, míg az olyan tényezők, mint a védjegy, a kilogrammonkénti ár vagy a tojás színe kevésbé befolyásolják a választásukat. Jelen tanulmányban csak a vásárlás és a fogyasztás során befolyásoló tényezők fontossága, valamint az ezekkel kapcsolatos vélemények kerültek bemutatásra. A rendelkezésünkre álló adatbázis alapján a hazai étkezési tojás fogyasztással és vásárlással kapcsolatos összefüggések alaposabb feltárására további vizsgálatok szükségesek.
Az ételfogyasztás megatrend kapcsolódásai
Authors: Törőcsik Mária
Published: March 2018

Jelen munka az ételek, az ételkészítés hívószavait, a velük összefüggésben lévő megatrendek bemutatását célozta meg. Tágabb perspektívában tekintette át, hogy mi minden mozog együtt a food-ról hozott döntéseink esetén.Az étel és az étkezés alapvető szükséglet az emberek számára. Tudjuk, hogy ez még ma sem mindenhol és mindenki számára biztosított. Azzal is tisztában vagyunk, hogy nálunk is sok embernek küzdelem a napi szükséges ételhez való hozzájutás. A választási lehetőséggel rendelkezők előtt viszont új perspektíva nyílt, mivel egyre szélesedő, mélyülő kínálat áll a rendelkezésükre. Különféle koncepciók vállalásával és megmutatásával hozhatják meg az ételválasztási döntéseiket. Az ételfogyasztás vizsgálata során növekvő jelentőséget tulajdoníthatunk a szimbolikus tartalmaknak. Kiderült, hogy az emberek megváltozott életritmusa, élet- és munkakörülményei, elvárásai és életstílusa eredményeképpen változatos food-trendek alakultak ki, és egyre újabbak várhatóak. Ezekre eltérően reagálnak az emberek, különbözőképpen fogadják el az újdonságokat, vagy utasítanak el fejlesztéseket, így karakteres fogyasztói csoportok alakulnak ki. Az étel egyre szélesebb körben alkalmas az életstílus és az értékek kifejezésére.

Active Return-to-Center Control Based on Torque and Angle Sensors for Electric Power Steering Systems
Authors: Du Pan-Pan , Su Hao , Tang Gong-You
Published: March 2018

This paper presents a complete control strategy of the active return-to-center (RTC) control for electric power steering (EPS) systems. We first establish the mathematical model of the EPS system and analyze the source and influence of the self-aligning torque (SAT). Second, based on the feedback signals of steering column torque and steering wheel angle, we give the trigger conditions of a state switch between the steering assist state and the RTC state. In order to avoid the sudden change of the output torque for the driving motor when the state switches frequently between the steering assist state and the RTC state, we design an undisturbed state switching logic algorithm. This state switching logic algorithm ensures that the output value of the RTC controller is set to an initial value and increases in given steps up to a maximum value after entering the RTC state, and the output value of the RTC controller will reduce in given steps down to zero when exiting the RTC state. This therefore ensures smooth switch control between the two states and improves the driver’s steering feeling. Third, we design the RTC controller, which depends upon the feedback signals of the steering wheel angle and the angular velocity. In addition, the controller increases the auxiliary control function of the RTC torque based on vehicle speed. The experimental results show that the active RTC control method does not affect the basic assist characteristics, which effectively reduces the residual angle of the steering wheel at low vehicle speed and improves the RTC performance of the vehicle.
Downhole Wettability: The Potential of NMR
Authors: Valori Andrea , Ali Farhan , Abdallah Wael
Published: March 2018

A review of several nuclear magnetic resonance (NMR) based techniques published in the literature to extract wettability information that have the potential to be applicable in downhole formation. The techniques include T2 shift, T2 vs saturation, NMR T1 dispersion, T1/T2 ratio, and restricted diffusion. The theoretical basis and the advantages and disadvantages of each have implications for downhole applications. Due to the flexibility of NMR, adjusting the experiment for the specific application is very common, and this shows the strength and flexibility of NMR. Numerous references provide detailed readings for each discussed technique.
Upscaling for Polymer Flooding
Authors: Al-Dhuwaihi Abdulaziz , King Peter , Muggeridge Ann
Published: March 2018

Polymer flooding is a proven EOR/IOR process for viscous and light oil reservoirs alike. However, it results in the formation of two shocks front that require simulation models with fine grid blocks to represent field scale fluid movement. Therefore, upscaling is required to transfer such fluid behavior to coarser models. However, most upscaling methods are designed for waterflood only, while upscaling techniques for polymer flood are rarely discussed in the literature.

In this paper, A new upscaling methodology specifically designed for polymer flooding is presented to address such impracticality. The methodology allows the average flow behavior to be captured, including the effects of small scale heterogeneity whilst compensating for the impact of increased numerical diffusion present in coarse grid models.

The method is based on the pore volume weighted method for relative permeability pseudoization first derived by Emanuel and Cook (1974) for waterflooding but extends its implementation to model polymer specific parameters such as adsorption isotherm and viscosity-concentration function. The method is demonstrated on a series of simple reservoir models for a range of different aggregation ratios, showing overall improvement in the prediction of oil recovery, water cut, produced polymer concentration with time, and pressure response in the coarse grid models. This is demonstrated by comparing the predictions from the coarse grid, upscaled models with those from fine grid simulations and coarse grid simulations of the same model reservoir without the new upscaling methodology.
Research and Application on Efficient Development Technology for Complex Heavy Oil Reservoir
Authors: LIN CUI
Published: March 2018

Accompanied with further development, fault blocks of multilayer complex heavy oil reservoirs will gradually face problems of great difficulty in stable production during late phase of CSS, low recovery efficiency of certain blocks and poor production of remaining oil between wells due to complicated geological conditions, deep buried oil reservoirs, high viscosity of heavy oil and other factors. Hence the way to effectively develop complex oil reservoirs and guarantee oil production is of great significance to realize the stable production of heavy oil reservoirs.

Based on different geologic characteristics and development statuses of complex oil and gas reservoirs, this project has carried out research and application through integrated utilization of various technologies and combination of innovations in development methods. In case of blocks with complicated structures, diversified depositional modes and substantial reservoir types, stratigraphic correlation based on logging and seismic data has been conducted, region-wide unified hierarchical model has been built to know the structure of entire region and build detailed 3-D geological models. Detailed profiling of structural characteristics and ‘four characters’ of reservoirs have been carried out, new standards for favorable oil reservoirs have been developed, and logging and seismic data have been combined to track favorable individual reservoirs. As for reservoirs with thin layers and microstructures, seismic inversion has been conducted for accurate identification, horizontal well techniques for thin layers have been used for overall development, optimal deployment of guide holes has been carried out, and steam flooding pilot test for extra heavy oil horizontal well in thin layers has been done to enhance recovery efficiency. In terms of problems of great difficulty in stable production of vertical well network during late phase of CSS and low recovery efficiency of certain blocks due to poor physical property and high viscosity, Technologies of overlapping horizontal well and multilateral horizontal well have been used in addition of accurate identification of oil-water relation for development, and the innovative development method of Gravity Drainage Assisted Steam Flooding has been created, which brought new ideas to viscous oil development.

It has been experimentally observed that Low-Tension-Gas (LTG) flooding can be a suitable enhanced oil recovery (EOR) method for low-permeability carbonate reservoirs with high salinity and hard formation brine. LTG flooding improves oil recovery by combining two effects: a reduction of the interfacial tension (IFT) between oil and water and mobility control through the formation of in-situ foam with an injected gas. However, the high cost of chemicals and/or the limited supply of gas can make this process economically challenging. In order to optimize the LTG process, an injection strategy has been designed such that the oil recovery can be maximized, using a minimum amount of the injected gas and the surfactant, thereby ensuring a more economically-viable recovery process. A low-permeable (<10 md) Middle Eastern limestone reservoir with a high formation brine salinity (~200,000 ppm and hardness 19,000 ppm) is the target reservoir of this study. Surfactant injection strategy was optimized by varying the concentration and pore volumes of the surfactant slug injected. Nitrogen gas was co-injected during select time periods throughout the entire chemical injection in order to identify the significance of mobility control during the crucial phases of the LTG flooding. The coreflood results emphasized the significance of the injection of gas, even at lower foam quality, for the maintenance of mobility control. Ultimate oil recovery of over 60% (residual oil post waterflood) was achieved, even after reducing the surfactant concentration by 75% and inducing a different in-situ salinity profile as compared to earlier studies. An innovative method for measuring surfactant adsorption using Liquid Chromatography and Mass Spectrometry (LC-MS) was developed, which could provide individual dynamic adsorption data for each of the three classes of surfactants used.

Kuwait Oil Company (KOC) has undertaken implementation of an Alkali-Surfactant-Polymer EOR pilot in probably the world's first carbonate reservoir in Sabiriyah Mauddud reservoir with billions of barrels in oil-in-place. This project in the North Kuwait area is being pursued with the help of industry experts in chemical EOR who are involved in conceptualization, pre-planning, pilot design and execution. A normal 5-spot, 5.5-acre pilot is presently operational since June 2017 with water injection in progress.

Encouraged by the excellent results of a series of Single Well Chemical Tracer Tests and of course and of course not unmindful of the risks, the company looks at this pilot as a ‘game changer’ with huge potential to enhance and sustain the North Kuwait oil production and reserve growth. It follows a path where an early lead could not only give it a distinct advantage in terms of achieving its goals but also create favorable conditions for commercial potential of this new technology. The decision to go ahead with this project is certainly backed an ambitious leadership with an appetite for entrepreneurial risk-taking and determination to succeed.

Commercial excellence in frontier technologies such as this would be determined after full evaluation of the ongoing or more pilots as necessary since there are no preexisting benchmarks for comparison.

The project continues to test and challenge the capabilities of individuals and the organizations alikeresearch financing, customization of chemical recipe for the reservoir, project logistics and economics being so demanding.

KOC views EOR as an opportunity to achieve its strategic medium and long-term objectives. The plan is to acquire and direct the cutting-edge technology of ASP flooding for unleashing the full production potential of its reservoirs to meet its 2040 strategy objectives.

In water injection operations, oil is displaced from the heterogeneous porous media that increases recovery factors while providing pressure support. The most important parameter to be considered in such water flooding operations is the mobility ratio. For increasing the mobility ratio to maximize volumetric sweep of injectants, gelling agents (polymers) are added to the injected water. Extreme temperature and shear stresses can result in the degradation of these polymers, i.e., long chain macromolecules of the polymer are split into smaller chains. Therefore, it is of utmost importance to select the right type and amount of these viscosity reducing agents for each reservoir.

In this paper, synthetic polymer mechanisms have been compared to a natural polymer (Xanthan), using a commercial full physics reservoir simulator. The assumption made in the simulation is simplified gel kinetics that forms a microgel without redox catalysis. The injection schedule is as follows; Continuous water injection over all 6 layers for first 450 days, gel system injection in the bottom two layers for the next 150 days and water injection is continued for 4 years. Reservoir model consists of a high permeability streak at the bottom of the reservoir while the top 4 layers have high horizontal permeabilities. The simulator is also coupled to an optimizer and an uncertainty analysis tool in which control and uncertainty variables are set to investigate the sensitivity under this process.

Simulated model results show that the gel penetrates deep within the reservoir model and the high permeability bottom layers are blocked. The relative merits of synthentic ploymers to natural polymers are obtained from the sensitivity studies. These suggest that Biopolymers and xanthan polymers have better performance in terms of viscosity effects whereas resistance factor and in-situ gelation treatments are highlighted for synthetic PAM. Adsorption and retention of polymer and gel are permeability dependent.

Given the potential for the application of polymers in reservoirs worldwide, this study compares and highlights the relative advantages of different treatments in terms of different parameters for the same model while showing the significance of each control and uncertainty variable. The economics of injecting different conformance enhancers have been analyzed as well in this study.

In present paper we ereport the evaluation and the application of Alkaline-Biosurfactant-Biopolymer (ABsBp) applications for enhancing oil recovery. Generally Alkaline-Surfactant-Polymer (ASP) studies have been carried out using chemical surfactants and polymers. This experimental investigation was performed to evaluate the possibility of using a biosurfactant and a biopolymer with sodium carbonate as an alkali for ASP flooding for the oil field. The candidate example reservoir was selected having favorable properties such as high permeability (500-1000 mD), low oil viscosity (20-25 cp), favorable total acid number (0.1 mg KOH/g oil) and high residual saturation (>20%). The current study was done to design an optimum composition of Alkali/Biosurfactant/Biopolymer (AbSbP) slug and apply it for enhancing oil recovery in both native reservoir cores and Berea sandstone core plugs. The interfacial tension (IFT) between various solutions containing alkali, biosurfactant and biopolymer was measured. Interfacial tension values in the range of 0.02-0.1mN/m were achieved at low biosurfactant and alkali concentrations. The interaction of the biopolymer with the brine, biosurfactant and alkali was investigated in terms of their effect on its viscosity at the reservoir temperature of 50°C. An AbSbP slug containing 1.1 wt.% sodium carbonate, 20 v/v% biosurfactant broth and 20 v/v% biopolymer broth was recommended for the final core flooding experiment. Core flooding experiments were conducted using reservoir cores and Berea cores by injecting the formulated AbS and AbSbP slugs after brine flooding. Maximum additional oil recovery obtained was 14% and 32% of oil initially in place (OIIP) from the reservoir cores and Berea cores respectively. Such difference in additional recovery was mainly due to the vast difference in the mineralogical composition of two rock types. This is the first report of application of Alkali-Biosurfactant-Biopolymer from Oman, showing additional oil from both native cores (from the Omani oil field) and Berea sandstone cores.

This study is about scale squeeze application for ASP pilot that was carried at Marmul field. This is first kind of scale squeeze treatment for ASP application. High pH associated with the ASP slug injection and production (pH>10.5) provides a rich environment for scale precipitation of metal ions when mixed with injection water. (1) Multiple activities associated with the scale squeeze treatment (evaluation, screening, modeling and application) were carried out from 2008 – 2016 in-house as well as with different vendors. It was quite challenging to find suitable scale inhibitor which is capable for scale inhibition at elevated pH and has longer squeeze life time.

The squeeze application was designed to start with a pre-flush stage to displace tubing fluids, acts as a spacer, condition the formation near the well bore and prevent water blocks/emulsions, followed by a main flush stage that has the highest concentration of SI in the mixed brine. Later on, a post flush stage was injected to displace the main flush further into the reservoir and increase adsorption. Finally, tubing displacement is injected which was about 5 m3 for each well.

The scale squeeze treatment for the four MM ASP production wells was completed prior to the ASP slug injection. A shut-in period for each well was applied to ensure adsorption of the chemical to the reservoir rock. Monitoring of the scale inhibitor return profile after the squeeze treatment for each well was carried out to determine the flow back characteristics and to evaluate the efficiency of the treatment. The monitoring evaluation has indicated that the scale squeeze treatment was successful in inhibiting the formation of scale in all of the four production wells and the concentration of the scale inhibitor was above MIC of 10 ppm. The scale inhibitor return profile concentration was also found to be in a very good alignment with the theoretical model and the treatment efficiency is passing the six months treatment life time period. This was successful implementation and proved the concept of appropriate propagation of SI from the formation to production system.
Investigating the Effect of Employing Inflow Control Devices on the Injection Well on the SAGD Process Efficiency Using an Integrated Production Modeling

Hot steam preparation for so long as of in the Steam Assisted Gravity Drainage (SAGD) process has proved very costly. The "Fort McMurray" reservoir in Alberta, as a large Canadian heavy oil resource, has undergone SAGD, to reach acceptable production rates. The published data was used to investigate new methods, such as that introduced in this paper, for further enhancing this popular heavy oil recovery method.

Lack of a uniform steam distribution along the horizontal injection well has demonstrated itself as a major challenge since a considerable portion of hot steam enters the reservoir through perforations near the heel. Thus, regions connected to the toe section of the well do not receive the heat required for equally reducing the heavy oil viscosity. On the other hands, Inflow Control Devices (ICDs) have been used successfully to create a uniform pressure distribution along horizontal wells by providing an extra pressure against the fluid flow near the wellbore.

This paper is aimed at conducting the simulation of injection/production systems in the SAGD process on the "Fort McMurray" reservoir. Three scenarios were defined to accurately investigate the effect of employing ICDs on the cumulative oil production as the objective function. The first scenario was designed and run with only one production well to highlight reservoir's poor ability in naturally delivering the oil to the surface. In the second scenario, an injection well was introduced through which hot steam was to be injected, to simulate the SAGD process and in the final case; this injection well was equipped with ICDs. Finally, results indicated a dramatic rise from 3.96 to 6.39 MMSTB in the cumulative oil production as a consequence of implementing ICDs in the injection well in the end of the injection/production period. Moreover, the recovery factor, initially was equal to 40.5%, was improved to 65.2%. Toe temperature, as another parameter to be monitored, experienced an increase of almost 75 °F and reached 400 °F following the use of these devices.

In this study, ICDs that had been mostly used in production wells, were utilized to make a smart injection well in the SAGD process which according to simulation results, were successful. Moreover, an integrated production modeling approach saw the reservoir, wells and surface facilities taken into account simultaneously to monitor the effect of interaction of different parts of the production system on eachother.
