An Innovative Dielectric Constant Measurement Method to Determine the Ideal Surfactant Candidate to Enhance Heavy Oil Recovery
Authors: Alshaikh M. , Huff G. , Hascakir B. 
Published: February 2018

Abstract
Steam injection is widely used enhanced oil recovery technique for heavy oil extraction. However, environmental and economic drawbacks of steam generation make the chemical additive-steam injection processes more favorable than steam injection alone. In this study, the performance of surfactant-steam flood process were investigated for heavy oil recovery and a quick recipe was proposed for the right surfactant selection through dielectric constant measurements.
Experiments were conducted on two heavy oil samples with different API gravity (12.09° and 11.56°) and viscosity (10,100 cP and 208,500 cP). Three anionic surfactants with same polar head group (sodium sulfate) but with different nonpolar tail length [long (SDS), moderate (SDeS), and short (SOS)] were selected to be tested. The crude samples and their SARA (Saturate, Aromatic, Resins, and Asphaltenes) fractions were blended with surfactant solutions at their critical micelle concentration (CMC). Interaction of crude oils, crude oils' non-polar fractions (Saturates and Aromatics) and crude oils' polar fractions (Resins and Asphaltenes) with surfactant solutions were visualized under optical microscope. An innovative and quick method, dielectric constant measurements were used to quantify indirectly the polarity of the blends. These measurements were used to determine the best surfactant candidates to recover each oil samples and accuracy of this new method was validated through optical microscopy images.
Microscopic images revealed asphaltenes have the higher contribution in the formation of micro-emulsions. It is observed that the polar-polar interaction of asphaltenes with resins adversely affected the surfactant performance due to reduction in overall polarity. We found that as the dielectric constant increases, the polarity of the oil/surfactant blends (microemulsions) increases which indicates that polar-polar interaction between oil/surfactant is minimized and the effectiveness of surfactants is maximized. Microscopic images were used to confirm this finding and for the blends having higher dielectric constants, minimum interaction of resins with surfactants and lower asphaltene aggregation for the same crude oil-surfactant blends were observed.
Our results offer that dielectric constant measurements can be used as an innovative and easy surfactant screening method.

Abstract
Boscan is a giant multi-billion-barrels heavy oil (10.5° API gravity and asphaltic) field in Venezuela. Although, a large part of the field is on primary production with a low recovery factor (&lt;6%), water injection has been successfully implemented in portions of the field for over 15 years with improved recovery. High mobility ratio waterflood (HMRWF) behavior and associated key production mechanisms obtained from detailed field data analysis and dynamic modeling are presented. A novel and unique infill configuration is also proposed to further improve recovery in this high (or adverse) mobility ratio environment.
Water injection in such heavy oil (10.5° API) was considered not effective by the industry previously, due to adverse mobility ratio. However, water injection for pressure maintenance (WIPM) was successfully implemented using a pattern configuration, pseudo 1-3-1 inverted 7-spot (an additional row of producer between conventional pattern rows). Field data and reservoir simulation models show increased reservoir pressure up to the second row of producers from the injector. The pressure support is utilized to significantly improve recovery using the unique configuration at low water cut. WIPM has already resulted in significant reserves addition. Current production from water injection areas is ~40 MBOPD (or ~ 47% field production).
However, it is estimated that because of high oil viscosity, a significant amount of oil remains bypassed in the WIPM area. An infill opportunity was identified from an integrated reservoir management study that included detailed WIPM data analysis and dynamic (mechanistic and full field) modeling. A unique infill configuration is proposed that conceptually uses the current injectors with an additional row of producers between the existing first and second row of the producers. This configuration has the potential to economically unlock millions of barrels of bypassed oil and significantly increase recovery in this prolific heavy oil field.
This study provides insights into HMRWF behavior evaluating relative impact of displacement vs. pressure. The unique and novel infill configuration can be used to improve recovery, a step vital to monetize this large resource in the low-price environment.
A Benchmarking Study of a Novel Data Physics Technology for Steamflood and SAGD Modeling: Comparison to Conventional Reservoir Simulation
Authors: Zhao Yong , Sarma Pallav 
Published: February 2018

Abstract
A novel modeling technology termed "Data Physics" that combines reservoir physics with machine learning is validated against a conventional reservoir simulator for thermal recovery problems, i.e., steam flooding and steam assisted gravity drainage (SAGD). The novelty of the new model is its combination of speed of data integration (less than a week) and runtime (minutes) with long-term predictive accuracy (years or decades). This is due to the unique integration of reservoir physics with fast data-driven methods. For accurate benchmarking, major sources of modeling errors in the finite difference simulations are screened and controlled. Two cases are studied, the SPE4 steamflood model, and a single pad SAGD model. The results demonstrate that the Data Physics model is able to reproduce production profiles and key reservoir physics accurately when numerical errors in simulation are properly accounted for, while also being immune to numerical issues like grid orientation effects that can have significant impact on results of reservoir simulation.
REDUCED OUT-OF-POCKET COSTS AND MEDICATION ADHERENCE – A POPULATION-BASED STUDY
Authors: Yao Shenzhen , Lix Lisa , Shevchuk Yvonne , Teare Gary , Blackburn David F 
Published: February 2018

Background: In 2007, a drug benefit plan for Seniors (SDP) was launched in Saskatchewan, Canada. SDP capped out-of-pocket costs at $15 per prescription for individuals aged 65 and older.
Objectives: To quantify the impact of the SDP on chronic medication adherence.
Methods: A retrospective cohort study was conducted for participants aged 65 or older who were eligible to the SPD, controlled by a younger group aged 40 to 64 who were ineligible. Adherence was measured over 365 days using medication possession ratio (MPR). MPRs were compared between age groups, and between pre and post SDP-launch periods. The odds ratio of optimal adherence (i.e., MPR≥80%) was estimated using logistic regression models with generalized estimating equations (GEE).
Results: Between 2005 and 2009, 353,568 adherence observations were observed from 188,109 unique patients. Comparing the post-SDP period vs before, the increase in the odds of optimal medication adherence was significant (OR=1.08, 95% CI: 1.04 to 1.11) and was stronger after excluding patients already receiving medication benefits from other government programs (OR= 1.21, 95% CI: 1.16 to 1.26). The SDP was associated with improved adherence among the subgroup of prevalent medication users (OR=1.08, 95% CI: 1.04 to 1.12), but not incident users (OR=1.05, 95% CI: 0.98 to 1.13).
Conclusion: Reducing out-of-pocket medication costs for seniors was associated with small improvements in medication adherence across the population.

Published: February 2018

Distribution outlet (distro) merupakan salah satu jenis UMKM yang ada di Indonesia. Dalam pengelolaannya dari proses pengadaan bahan baku, produksi sampai transaksi penjualan umumnya masih menggunakan sistem konvensional. Sistem konvensional tersebut menyebabkan pengelola distro tidak dapat memonitor secara real time pergerakan omset penjualannya. Penelitian ini dimulai dengan pengumpulan data primer dan sekunder. Data yang telah dikumpulkan dianalisis, kemudian dilakukan implementasi menggunakan dua perangkat lunak. Perangkat lunak yang digunakan dalam implementasi adalah www.erzap.com (ERZAP) oleh Z4Comp.com dan www.tradegecko.com (TRADEGECKO) oleh TradeGecko Pte. Ltd. Dua perangkat lunak tersebut diuji dan dianalisis terkait ketersediaan fitur-fitur dasar dalam implementasi e-SCM. Hasil penelitian menunjukkan bahwa sistem konvensional yang berjalan saat ini pada usaha distro hanya cukup untuk menangani transaksi dalam skala regional saja. Dengan mengimplementasikan suatu sistem e-SCM diharapkan dapat meningkatkan efisiensi produksi dan mengefektifkan distribusi barangnya. E-SCM dapat mengintegrasikan keseluruhan data pengelolaan distro terkait dengan manajemen rantai pasokan mulai dari hulu sampai hilir. Terdapat beberapa elemen supply chain yang tidak dimiliki oleh kedua sistem. Seperti misalnya elemen planning yang tidak ada pada ERZAP dan elemen planning dan production tidak ada pada TRADEGECKO.

Sohrab Sepehriis concidered as one of the geniuses of Persian poetry by creating the artistic and mythical themes. The present study is a descriptive-analyticeone which data has been collected on the basis on “library method” and the word “Loneliness” has been accurately studied in Sohrab Sepehri complete poetical work with the psychological approach to language.In this research, Sohrab Sepehri`s complete poetical worka in the book named “hasht ketab” have been scrulinized according to Leech view (1969).The author seeks to answer these questions: what items has Sohrab Sepehri benefited from to present the element “loneliness”on the basis of psycholinguistics? And which of his books has presented the highest frequency of the element “loneliness”? This research illustrates the fact that Sohrab Sepehri has benefited from “Sense of Words” and due to the fact that he has also been a skillful painter besides being an out standing poet, it is speculated that he has also used the element “color of words”. The results indicate the element of loneliness has been found to be a very significant item in Sohrab Sepehri`s poetical works, but the frequency of presenting this element overweighs in one of his books named “Death of color”.
