Foaming Behavior of CO2-Soluble, Viscoelastic Surfactant in Homogenous Porous Media
Authors: Ramadhan Galang , Hirasaki George , Nguyen Quoc P.
Published: March 2018

Aqueous foam has been demonstrated through laboratory and field experiments to be a promising conformance control technique. This study explores the foaming behavior of a CO2-soluble, cationic, amine-based surfactant. A distinguishing feature of this surfactant is its ability to dissolve in supercritical CO2 and to form Wormlike Micelles (WLM) at elevated salinity. Presence of WLM led to an increase in viscosity of the aqueous surfactant solution. Our study investigates how the presence of WLM structures affect transient foam behavior in a homogenous porous media (sand pack).

Sand pack foam flooding experiments were performed with two aqueous phase salinities: low salinity (15 wt. % NaCl) associated with spherical-shaped micelle and high salinity (20 wt. % NaCl) associated with WLM. We compared the onset of strong foam propagation and foam apparent viscosity buildup rate between the two salinity cases. The effect of WLM presence in transient foam behavior was investigated for co-injection and water-alternating-gas (WAG) injection strategies. In all foam flooding experiments, the surfactant was delivered in the CO2 phase.

Strong foam was generated in all foam flooding experiments, with an apparent foam viscosity of at least 600 cp for co-injection and 200 cp for WAG floods after five total injected pore volumes. The observed strong foam indicated that the delivery of surfactant in the CO2 phase was successful and that the surfactant molecules partition to the water phase in the sand pack. In comparison to the low salinity cases, the high salinity foam floods associated with the presence of WLM led to better foam performance. We observed an earlier onset of strong foam propagation as well as a higher apparent viscosity buildup rate. Better foam performance at higher salinity may be attributed in large part to the presence of WLM structures in the foam liquid phase. Entanglement of these WLM structures may have led to in-situ viscosification of the foam liquid phase and an increase in disjoining pressure between foam films. Both phenomena may have reduced the rate of foam film coalescence.

WLM structures behave similarly to polymer molecules. Our study may offer evidence that WLM is a valid alternative to polymer as an additive to enhance foam conformance control performance. Some potential advantages of WLM over polymer include: Delivery of surfactant in the gas phase (to alleviate the injectivity issue typically associated with high viscosity polymer-surfactant solution), resistance to extreme temperature and salinity, and reversible shear degradation.
An Update on Full Field Implementation of Chemical Flooding in Daqing Oilfield, China, and Its Future
Authors: Yin Shize , Pu Hui , Zhou Shide
Published: March 2018

The implementation of chemical fooding such as polymer flooding and alkaline/surfactant/polymer (ASP) flooding in Daqing oilfield is presented in this paper. The annual crude oil production rate by chemical EOR in Daqing oilfield has been kept over 73.3 million barrels per year for 15 consecutive years. According to the actual field production data, the incremental oil recoveries by polymer flooding is over 10% OOIP and incremental oil recovery by ASP flooding is more than 20% OOIP over that of waterflooding. This paper discusses the progresses made in Daqing over the last 30 years, including crucial application strategies, optimized design of surface facilities, field results, methods to solve technical challenges of chemical flooding, strategies to reduce cost for commercial-scale chemical EOR, and future development direction, especially future development plan for ASP. Four major lesssons are obtained for the best quality reservoirs defined as First Class oil layers in Daqing oilfield, in which polymer flooding has been completed. The existing problems are described for the medium and poor quality reservoirs defined as Second or Third Class, in which polymer flooding or ASP flooding is in progress, and the strategies are proposed, such as injection mode optimization, optimization of injection parameters, optimization of adjustment measures, optimization of well spacing, subdivision of pay zones, separate layer injection, optimization of slug combination, etc. This paper also proposes policy guidance for chemical flooding adjustment in Daqing oilfield in the coming years and provides references for chemical flooding production in other oilfields.
The Onset of Spontaneous Imbibition: How Irregular Fronts Influence Imbibition Rate and Scaling Groups
Authors: Føyen T. L. , Fernø M. A. , Brattekås B.
Published: March 2018

Spontaneous imbibition is a capillary dominated displacement process where a non-wetting fluid is displaced from a porous medium by the inflow of a more-wetting fluid. Spontaneous imbibition strongly impacts waterflood oil recovery in fractured reservoirs and is therefore widely studied, often using core scale experiments for predictions. Decades of core scale experiments have concluded that spontaneous imbibition occurs by a uniformly shaped saturation front and that the rate of imbibition scales with square root of time. We use emerging imaging techniques to study local flow patterns and present new experimental results where spontaneous imbibition deviates from this behavior.

The imbibition rate during early stages of spontaneous imbibition (the onset period) was sometimes observed to deviate from the square root of time behavior. The impact of the onset period on the imbibition process is, however, not well understood. In this work, the development of displacement fronts were visualized during the onset period, using twodimensional paperboard models and core plugs imaged using Positron Emission Tomography (PET-CT). The new experimental results provided insight on the dynamics during the initial spontaneous imbibition period. Controlled two-dimensional paperboard experiments demonstrated that restricted wetting phase flow through the surface exposed to water caused irregular saturation fronts and deviation from the square root of time behavior during the onset period. Local restriction of the wetting phase flow was observed during spontaneous imbibition in sandstone core plugs as a result of non-uniform wetting preference. The presence of nonuniform wetting resulted in unpredictable spontaneous imbibition behavior, with induction time (delayed imbibition start) and highly irregular fronts. Without imaging, the development of irregular saturation fronts cannot be observed locally; hence the effect cannot be accounted for, and the development of spontaneous imbibition in the core erroneously interpreted as a corescale wettability effect. This underlines the undeniable need for a homogenous wettability preference through the porous medium when performing laboratory spontaneous imbibition measurements. Our observations of non-uniform wetting preference will affect Darcy-scale wettability measurements, scaling and modeling. We argue that great care must be taken when preparing core plugs for spontaneous imbibition, to avoid experimental artifacts.

Published: March 2018

This paper summarizes the overall response from the CO2-foam injection in the Salt Creek field, Natrona County, Wyoming. Conformance control of CO2 by creating foam between supercritical CO2 and brine to improve the sweep efficiency is documented in this paper. The foam was implemented in an inverted fivespot pattern in the Salt Creek field where the second Wall Creek (WC2) sandstone formation is the primary producing interval, with a net thickness of about 80 ft and at a depth of approximately 2,200 ft. The initial phase of the foam pilot design involving identifying the pilot area, performing coreflood experiments, performaing dynamic reservoir simulation for history match, and forecasting with foam have been documented in the literature. As a part of the foam pilot monitoring, a gas tracer study was performed before and after the injection of foam in the reservoir. The initial planning, monitoring, and part of foam response is covered in earlier publications. The last surfactant injection in the field was in June 2016. This paper provides the complete analysis of the results from the foam pilot. The foam pilot was successful in demonstrating the deeper conformance control and improvement in sweep efficiency, which resulted in 25,000 bbl of incremental oil. Also overall, a 22% decrease in CO2 injection amount is realized due to better utilization of CO2 compared to the baseline.
Use of Cross-Linked Polymer Systems to Improve Volumetric Sweep Efficiency and Alternative Full Field Development Strategy for a Mature Waterflooding Optimization Processes - Dina Cretaceous Field Case
Authors: Leon J. M , Izadi M. , Castillo A. , Zapata J. F. , Chaparro C. , Jimenez J. , Vicente S. E. , Castro R.
Published: March 2018

The Dina Cretaceous field, operated by Ecopetrol S.A., is located in the Upper Magdalena Valley (UMV) Basin in Colombia. The field discovered in 1969, reaching maximum primary oil rate of 6,500 BOPD in May 1980. Secondary recovery mainly by peripheral water injection started in 1986, achieving a maximum production of 9,850 BOPD in January 1988. Subsequently, water production has increased rapidly accompanied by declining oil production, due primarily to reservoir heterogeneity and an unfavorable mobility ratio. The oil recovery factor as of October 2017, as a percentage of OOIP, is estimated to be approximately 33% at a current water cut of about 97%.

Ecopetrol S.A in 2009, began to look for new development strategies that would allow optimizing the oil recovery for this asset. Several IOR/EOR technologies were screened to reduce water production and increase sweep efficiency. Polymer gels ("Conformance treatments"), polymer flooding and cross-linked polymer also known as Colloidal Dispersion Gels (CDG) are some of the technologies most commonly used during the last few decades for this purpos. Based on screening study, detailed production and injection data analysis, water channeling, reservoir heterogeneity, adverse mobility ratio, laboratory evaluation and simulation results, the cross-linked polymer systems (CDG) were implemented in four patterns between 2011 and 2015. This would allow to increase the volumetric sweeping efficiency both for mobility control, in-depth conformance control and leading to viable project both technically and economically.

This paper presents the implementation and results of the injection of cross-linked polymer systems in the Dina Cretaceous field. A summary of the maturation process is presented, from conceptual design, experimental evaluation, engineering analysis, numerical simulation, pilot execution, process monitoring and field expansion strategy, as well as the results obtained in the pilot.

The results of the pilot were satisfactory both technically and economically and lead to a new development plan for the field. This new plant is focused on the optimization of the waterflood, pattern reconfiguration, infill drilling, selective injection, and improving the sweep efficiency through the injection of cross-linked polymer across the field in 11 more patterns.
Application of Surfactants in Shale Chemical EOR at High Temperatures
Authors: Zeng Tongzhou , S. Miller Chammi , Mohanty Kishore
Published: March 2018

The goal of this work is to develop surfactant systems that can improve oil flow from shale wells after fracturing or re-fracturing. Surfactants can reduce oil-water interfacial tension and wettability of the shale, which in turn can improve water imbibition, increase oil relative permeability and reduce water blockage at the matrix-fracture interface. Temperature in typical shale reservoirs are high and the surfactants need to be aqueous stable to be effective in these treatments. Mixing two surfactants often gives higher aqueous stability than those of the single surfactants. A large number of surfactants (anionic, non-ionic and cationic) and their blends were studied for aqueous stability, contact angle and spontaneous imbibition. Seven single surfactants and nine surfactant blends were found to be stable in both high and low salinity brines at 125 °C. All aqueous stable blends changed wettability of oil-wet shale to preferentially water-wet in both high and low salinity brines. Seven single surfactants and five surfactant blends were tested for imbibition. Surfactant solutions improved water imbibition to the extent of 20% PV. Surfactant blends improved imbibition more than the single surfactants. Imbibition in cores reached a plateau in about 3 days. Surfactant blends have the potential to be used in low salinity fracturing or refracturing fluids to stimulate shale wells.
A New Mathematical Model of Solvent - SAGD Process - Importance of Heat and Mass Transfer
Authors: Zargar Zeinab , Ali S. M.
Published: March 2018

The current in situ exploitation of oil sands in Alberta employs steam-based recovery methods, which are energy-intensive. A few companies are adding solvent to steam aiming to reduce steam requirements. The mechanism of oil recovery by steam with added solvent is not clear. Over the years, on several occasions- as at the present time- the oil industry has resorted to the use of solvents with steam in thermal recovery operations. The past trials with solvent were short-lived in view of the cost of solvents as well as the lack of success. Given the controversy regarding the use of solvents with steam, this work is intended to explain whether solvent injection with steam increases oil recovery or not.

In this work, a new analytical model is developed for describing the solvent-SAGD performance based on the combination of an overall solvent mass balance, heat balance and volumetric oil displacement and Darcy's oil rate using a mixture viscosity model as a function of temperature and solvent concentration ahead of front which satisfy the equilibrium in the system.

The objectives of this work are to predict: vapour-steam chamber growth, oil production rate, solvent production rate, solvent loss (or solvent retention) rate, and the effect of solvent type and concentration on the solvent-SAGD process. The results show that the rate of solvent retention increases over time, while the production rates of solvent and bitumen decrease.

The efficiency of this process is evaluated using Cumulative Steam-Oil Ratio (CSOR) and cumulative solvent-oil ratio, which permits a comparison of the efficiency of SAGD and solvent-SAGD processes for different solvents. On the whole, the results of this approach give a better understanding of the mechanism of oil production during the solvent-SAGD process by interconnecting vapour chamber conditions and the conditions of heated and diluted oil ahead of the interface.

latent classes was found to fit the data best. According to this model, when
the difficulties and discrimination averages of the items are taken into
account, it can be expressed that items are moderately difficult and discriminative for students in latent
class-1; the items are considerably easy and able to slightly distinguish the students in  latent class-2; the items are difficult to
the students in the third latent class and they can slightly distinguish the
students in this group.
Introducing Global Issues in A Language Classroom: Knowing Other Cultures by Analysing Multimodal Texts from NGOs
Authors: Martínez Lirola María
Published: March 2018

This article shows the importance of teaching with texts from Non-Governmental Organizations (NGOs) in which women from other cultures are represented in order to bring global issues in a language classroom and to deepen in the visual representation of women from other cultures so that students develop their gender perspective. Our main objectives with the research presented in this paper are to introduce students to visual grammar and to work with texts that allow students at tertiary level develop critical thinking and respect for cultural diversity, which will contribute to the introduction of global issues into the classroom. Kress and van Leewen (2006) model of visual grammar was introduced in an English language course at University level so that students could read and analyse multimodal texts. Having done this, students were asked to analyse the texts in groups in order to observe the importance of visuals in the construction of meaning and the way in which the women represented appeared portrayed. The analysis using visual grammar shows that the texts under analysis portray a positive image of African women, which breaks the traditional stereotypes of these women being weak, dependent and marginalised. In addition, this research will show that teaching global issues using multimodal texts from the NGO Intermón Oxfam will help students understand how the discourse used by NGOs creates meaning through different visual and linguistic choices.

The bacterial resistance to antibiotics constitutes more than ever a severe public health problem.
The enzymes involved in bacterial peptidoglycan biosynthesis are pertinent targets for developing
new antibiotics, notably the MraY transferase that is not targeted by any marketed drug. Many research
groups are currently working on the study or the inhibition of this enzyme. After a concise overview of
the role, mechanism and inhibition of MraY, the structure–activity relationships of 5’-triazole-containing
aminoribosyluridine inhibitors, we previously synthetized, will be presented. The recently published
MraY X-ray structures allowed us to achieve a molecular virtual high-throughput screening of commercial
databases and our in-house library resulting in the identification of promising compounds for the further
development of new antibiotics.
Potential Pharmacokinetic Herb-Drug Interactions: Have we Overlooked the Importance of Human Carboxylesterases 1 and 2?
Authors: Xu Jing , Qiu Jin-Chun , Ji Xing , Guo Hong-Li , Wang Xuan , Zhang Bo , Wang Tengfei , Chen Feng
Published: March 2018

Background:

Herbal products have grown steadily across the globe and have increasingly been incorporated
into western medicine for healthcare aims, thereby causing potential pharmacokinetic Herb-drug Interactions
(HDIs) through the inhibition or induction of drug-metabolizing enzymes and transporters. Human Carboxylesterases
1 (CES1) and 2 (CES2) metabolize endogenous and exogenous chemicals including many important therapeutic
medications. The growing number of CES substrate drugs also underscores the importance of the enzymes. Herein,
we summarized those potential inhibitors and inducers coming from herbal constituents toward CES1 and CES2. We
also reviewed the reported HDI studies focusing on herbal products and therapeutic agents metabolized by CES1 or
CES2.

Methods:

We searched in PubMed for manuscript published in English after Jan 1, 2000 combining terms “carboxylesterase
1”, “carboxylesterase 2”, “inhibitor”, “inducer”, “herb-drug interaction”, “inhibitory”, and “herbal supplement”.
We also searched specific websites including FDA and EMA. The data of screened papers were analyzed and
summarized.

Results:

The results showed that more than 50 natural inhibitors of CES1 or CES2, including phenolic chemicals,
triterpenoids, and tanshinones were found from herbs, whereas only few inducers of CES1 and CES2 were reported.
Systemic exposure to some commonly used drugs including oseltamivir, irinotecan, and clopidogrel were changed
when they were co-administered with herb products such as goldenseal, black cohosh, ginger, St. John’s Wort, curcumin,
and some Chinese compound formula in animals.

Conclusion:

Nonclinical and clinical studies on HDIs are warranted in the future to provide safety information toward
better clinical outcomes for the combination of herbal products and conventional drugs.
Network Pharmacology: Exploring the Resources and Methodologies

Published: March 2018

Multi-target and combinatorial therapies have been focused for the past several decades.
These approaches achieved considerable therapeutic efficacy by modulating the activities of the targets
in complex diseases such as HIV-1 infection, cancer and diabetes disease. Most of the diseases cannot
be treated efficiently in terms of single gene target, because it involves the cessation of the coordinated
function of distinct gene groups. Most of the cellular components work efficiently by interacting with
other cellular components and all these interactions together represent interactome. This interconnectivity
shows that a defect in a single gene may not be restricted to the gene product itself, but may spread
along the network. So, drug development must be based on the network-based perspective of disease
mechanisms. Many systematic diseases like neurodegenerative disorders, cancer and cardiovascular
cannot be treated efficiently by the single gene target strategy because these diseases involve the complex
biological machinery. In clinical trials, many mono-therapies have been found to be less effective.
In mono-therapies, the long term treatment, for the systematic diseases make the diseases able to acquired
resistance because of the disease nature of the natural evolution of feedback loop and pathway
redundancy. Multi-target drugs might be more efficient. Multi-target therapeutics might be less vulnerable
because of the inability of the biological system to resist multiple actions. In this study, we will
overview the recent advances in the development of methodologies for the identification of drug target
interaction and its application in the poly-pharmacology profile of the drug.
Brain Responses Underlying Anthropomorphism, Agency, and Social Attribution in Autism Spectrum Disorder
Authors: Ammons Carla J. , Doss Constance F. , Bala David , Kana Rajesh K.
Published: March 2018

Background:

Theory of Mind (ToM), the ability to attribute mental states to oneself and others, is frequently impaired in Autism Spectrum Disorder (ASD) and may result from altered activation of social brain regions. Conversely, Typically Developing (TD) individuals overextend ToM and show a strong tendency to anthropomorphize and interpret biological motion in the environment. Less is known about how the degree of anthropomorphism influences intentional attribution and engagement of the social brain in ASD.

Objective:

This fMRI study examines the extent of anthropomorphism, its role in social attribution, and the underlying neural responses in ASD and TD using a series of human stick figures and geometrical shapes.

Methods:

14 ASD and 14 TD adults watched videos of stick figures and triangles interacting in random or socially meaningful ways while in an fMRI scanner. In addition, they completed out-of-scanner measures of ToM skill and real-world social deficits. Whole brain statistical analysis was performed for regression and within and between group comparisons of all conditions using SPM12’s implementation of the general linear model.

Results:

ToM network regions were activated in response to social movement and human-like characters in ASD and TD. In addition, greater ToM ability was associated with increased TPJ and MPFC activity while watching stick figures; whereas more severe social symptoms were associated with reduced right TPJ activation in response to social movement.

Conclusion:

These results suggest that degree of anthropomorphism does not differentially affect social attribution in ASD and highlights the importance of TPJ in ToM and social attribution.

Authors: Darwesh Ali K. , Rasmussen Thorkild M. , Al-Ansari Nadhir
Published: March 2018

Background:

This paper discusses the wiper trip effects on well instability in shale formations.

Objectives:

Problematic shale interval sections have been studied for the time spent on the wiper trip operations. Lifting efficiency and well wall instability change with the time analyzed. Detailed drilling operation, formation heterogeneity, rheological and filtration characteristics of polymer water-based mud are discussed. Physical and chemical properties of the drilled formation and drilling fluid are also studied.

Materials and Methods:

Wiper trips are analyzed using a typical drawing program to find the relations between the most controllable parameters. For that, two calculation models have been implemented to find the net rising cutting particles velocity in the annular. The relation between the net rising velocity and wiper trips is analyzed. Laboratory works have been done to support the findings of field work.

Results:

Strong relations have been found between the wiper trip impacts and lithology types of the penetrated shale.

Conclusion:

A modified drilling program is proposed in relation to changes in casing setting depth and drilling fluid properties that make the operations more efficient in cost and time.
Recent Trends of Marriage in Iran
Authors: Aghajanian Akbar , Vaezzade Sajede , Kohan Javad Afshar , Thompson Vaida
Published: March 2018

Background:

In Iran, historically, establishing, maintaining, and continuing family units have been perpetuated through the development of strong ideals about marriage and reproduction that are integrated with Islamic values. Despite the long tradition of marriage as the foundation of both family and society, the data show there are declines in both the rate and the number of marriages. The popular belief among both laymen and social scientists is that, while there has been a decline in permanent marriages, there has been an increase in the number of what can be called temporary marriages. There are no data demonstrating trends in these marriages.

Methods:

In this paper, we present data on the declining trend in marriage and review the literature on factors considered as a barrier toward marriage. In addition, we examine data from a snowball sample of couples involved in temporary marriages orSighe.

Results:

Our analysis suggests that those in such marriages may generally ignore or defy cultural prescriptions and proscriptions about marriage, seemingly reflecting a more modernistic view.

Conclusion:

From this perspective, we suggest that both recorded and non-recorded temporary marriages may reflect changing attitudes that stress individualism, autonomy, and secularism and, particularly for the young who are engaged inSighe, the postponing of parenthood and, indeed, of adulthood.

Published: March 2018

The built environment affects thermal conditions in an urban space, thereby affecting the visitors’ thermal comfort. The objective of the study is to determine the effects of landscape attributes on microclimatic conditions and public thermal perceptions at an urban square in temperate and dry region. Simultaneous measurement and questionnaire surveys were conducted in winter and summer in Isfahan, Iran. Thermal stress was found to be higher in summer than in winter. Evaporative cooling by water and providing more air velocities were two useful ameliorating strategies. The visitors were most sensitive to changes of air temperature (Ta) rather than other parameters.Keywords: Thermal comfort; built environment; urban square; microclimates eISSN 2398-4295 © 2018.

BACKGROUND

End-stage renal disease (ESRD) is the last stage of chronic kidney disease, mainly caused by type 2 diabetes mellitus and characterized by an increased mortality risk related to cardiovascular disease. Low-dose aspirin (acetylsalicylic acid or ASA) seems to effectively prevent cardiovascular events in patients with ESRD. However, the number of interventional studies in this population remains limited and the mechanisms of aspirin-related bleeding remain poorly understood. Aspirin’s efficacy and safety may be modified by the presence of type 2 diabetes mellitus or platelet hyperreactivity.

OBJECTIVE

The overall objective of this protocol is to (1) evaluate aspirin’s safety and efficacy in reducing the risk of thrombotic events in patients with ESRD on hemodialysis and (2) examine whether aspirin’s efficacy is modified by the presence of type 2 diabetes mellitus or platelet hyperreactivity. Specifically, the primary objective is to compare the 12-month rate of any thrombotic event (cardiac death, nonfatal myocardial infarction, nonfatal stroke, arteriovenous fistula thrombosis) and Thrombolysis in Myocardial Infarction (TIMI) major bleeding in patients treated with aspirin compared to those on placebo. Secondary objectives are to test for effect modification of treatment by the presence of type 2 diabetes mellitus or platelet hyperreactivity and compare the rate of TIMI minor bleeding between treatment groups.

METHODS

We developed a protocol for a phase 2 randomized, single-center, placebo-controlled, triple-blind, superiority clinical trial to assess the prophylactic efficacy and safety of aspirin in patients with ESRD and on hemodialysis. It follows the ethical principles of the Declaration of Helsinki of the World Medical Association. A total of 342 participants would be enrolled over 12 months at a large dialysis center. Patients will be randomized in a 1:1 ratio and stratified by presence of type 2 diabetes mellitus and platelet hyperreactivity to receive either oral aspirin (100 mg/d) or placebo for a treatment period of 12 months. An intention-to-treat statistical analysis will be performed.

RESULTS

PLEASE WRITE RESULTS.

CONCLUSIONS

We provide a protocol for a randomized controlled trial to evaluate the safety and efficacy of treatment with aspirin to reduce the risk of thrombotic events. In addition, such a study would further our understanding of the mechanism of aspirin-related bleeding and help identify subgroups of best-responders and patients with a higher risk of adverse events.
