Problem-Based Learning: An Experiential Strategy for English Language Teacher Education in Chile
Authors: Muñoz Campos Diego
Published: January 2017

The Chilean education system requires English language teachers to be equipped with non-conventional teaching strategies that can foster meaningful learning and assure successful learners’ performances in diverse and complex settings. This exploratory, descriptive, research study aimed at discovering the perceptions of 54 pre-service teachers about the impact of a problem-based learning activity in the development of key competencies, including higher order thinking skills and reflective, research, knowledge transfer/integration, social, and self-management skills. Groups of participants chose a made-up, ill-structured problem which combined language teaching and socio-cultural issues, and devised holistic solutions. Findings suggest a comprehensive impact on the first four skills, but a limited impact on social and self-management skills.
Comparing the Internet Usage of Pre-service Language Teachers With Teachers of Other Subjects: Distance Learning vs. On-Campus Learning
Authors: Firat Mehmet , Serpil Harun
Published: January 2017

Teachers play a crucial role in helping individuals gain adequate Internet competency, which requires teachers themselves to be Internet-literate. The purpose of this study is to investigate the Internet use of the distance and on-campus pre-service teachers of language and other disciplines by multiple parameters. A total of 789 teacher candidates participated in this survey. The findings show that the candidate teachers in on-campus and distance-learning programs have an average level of Internet usage adequacy and that the younger candidate teachers and those in higher classes use the Internet more frequently. Pre-service foreign language teachers have been found to have a moderate level of Internet usage frequency, adequacy and technology ownership in comparison with the other preservice teacher groups.
A Learning Experience of the Gender Perspective in English Teaching Contexts
Authors: Mojica Claudia Patricia , Castañeda-Peña Harold
Published: January 2017

Eighteen Colombian English teachers participated in a course with an emphasis on gender and foreign language teaching in a Master’s program in Bogotá. This text describes the design, implementation, and the learning in this educational experience. The analysis of the course was based on a view of learning as a process of participation rooted in the praxis of English teachers’ classrooms. This experience reveals that gender is a relevant category in the frame of English language teacher education as it provides teachers with tools from a broader social and educational perspective. This reflection also leads to implications for teachers’ practices with a gender perspective.

To start, the exercise of writing is a difficult task. Nothing more challenging than the whiteness of an empty page. Whether the writing outcome is a personal product or a piece to be socialized in the academic world, the writing task demands a lot from the ones that succumb by pleasure or obligation to the writing assignment. Apart from the skill of writing, authors of articles published in academic journals are obliged to stick to the specific publication’s parameters. Strict datelines, number of words and specific sections to be included will shape the writer’s production. The resulting texts in most of the circumstances will fit the publications’ guidelines but may, in turn, restrict the writer’s flow and line of thought. Authors may be restricted by limitations but if they want to publish they should stick to the parameters of the target publication. In other words, stick and publish or ignore and be ignored.

Authors: Park Jong-Il , Kang aNam-Jung , Lee Sang-Min , Kim Sehun , Oh S. J. , Ri H. C. , Cheon Jinwoo
Published: January 2017

Synthesis of ‘solid solution’ and ‘core-shell’ types of well defined Co-Pt based nanoalloys smaller than 10nm have been achieved by redox transmetalation reactions. This redox transmetalation are selectively observed only if the redox potential between two metals is favorable. The composition of the magnetic alloys can also be tuned by adjusting the ratio of reactants. Annealed core-shell nanoparticles transformed into mixed nanoalloys with face centered tetragonal (fct) structures, which show large coercivity and ferromagnetism at room temperature. These nanoparticles can potentially be used as an independent single magnetic bit of tera-bit information storage. Also, this kind of redox transmetalation reaction can be utilized as a general process to synthesize various types of nanoalloys with controlled composition in a selective fashion.
Texture of Polycrystalline MoSxThin Films Magnetron Sputtered from a Metallic Target in Ar-H2S Atmospheres
Authors: Weiß Volkmar , Mientus Rainald , Ellmer Klaus
Published: January 2017

The textured film growth of polycrystalline MoSxfilms on Si substrates deposited by reactive magnetron sputtering with H2S from a molybdenum target has been investigated. Over a wide range of gas flow ratios FH2S/(FH2S+FAr) from 1% to 75% only x-ray diffraction patterns of randomly stacked S-Mo-S layers of the MoS2phase were detected which indicates turbostratic growth of the van-der-Waals layers comparable to the growth of graphite at low temperatures. The extended distance of the c-lattice planes depends on the sputtering conditions and can also be explained by the turbostratic model. Low deposition rates and high substrate temperatures improved the quality of the films towards the requested (001) texture and low c-lattice strain. The results from the in situ-energy dispersive x-ray diffraction (EDXRD) technique using synchrotron radiation allowed kinetic calculations of the time dependent behaviour of the peak area of the (0 0 21) Bragg reflection signals according to the Johnson-Mehl-Avrami model. They revealed that the grain growth is restricted in dimensions if a completed nucleation is assumed.
Who CARES? Interprofessional Competencies for Meeting the Complex Needs of Culturally and Linguistically Diverse Foster Youth With Disabilities
Authors: Green Tonika Duren , Mathiesen Sally G.
Published: January 2017

This paper highlights effective interprofessional competencies for school professionals who are interested in improving the educational path of culturally diverse foster youth who are at risk of a disability or who have a disability. The interprofessional competencies were developed based on the lessons learned in the first three years of a federally funded grant. We propose cost-effective ways to address shortages of highly qualified school personnel to work with diverse foster youth with disabilities. Recommendations to improve practice with diverse foster youth with disabilities include increasing the number of Culturally Affirming and Responsive Education Specialists (CARES; school social workers, school counselors, and school psychologists) who are trained to respond to the educational and mental health needs of diverse foster youth with disabilities, who are culturally competent, who are advocates in schools, and who are skilled at interdisciplinary service delivery.
Preparing MSW Students to Provide Integrated Behavioral Health Services in Rural Communities: The Importance of Relationships in Knowledge-Building and Practice
Authors: Rishel Carrie W. , Hartnett Helen P. , Davis Brandi L.
Published: January 2017

The provision of behavioral health care services is dramatically changing. Specific components of the Affordable Care Act (ACA) encourage states to develop integrated models of service delivery that emphasize preventative services. This shift prompts the need for providers who understand the interrelationship among physical and behavioral health and who are prepared to practice in an interprofessional and team-based approach. This article presents preliminary evaluation results from the initial implementation of the Integrated Mental and Behavioral Health Training Program (IMBTP) within an MSW program which emphasizes rural practice. The IMBTP is funded through federal grants aimed at increasing the number of behavioral health providers nationwide. Results suggest that an intentional focus on relationships enhances the knowledge-building and skill development that are inherently emphasized in most training programs. Including opportunities for relationship-building both among trainees and with program faculty, clinical supervisors, and interprofessional colleagues may improve learning outcomes in behavioral health training programs.
Teaching Macro Social Work through Experiential Learning: Student Reflections on Lessons Learned in Building School-Community Partnerships
Authors: Blitz Lisa V. , Yull Denise , Solá Martha G. , Jones John E.
Published: January 2017

A faculty-led experiential learning project was implemented with Master of Social Work students at their field placement sites to teach macro practice skills and research methods. As part of a grant-funded school-university partnership, MSW students were placed in school social work field placements, where their practice focused on individual and small group interventions with youth. Ten MSW students participated in asset-based collective family engagement in diverse, low-income communities, using community organizing skills and community-based participatory research methods. To examine student learning, a pilot study gathered narrative data from seven of the students and three supervisors. MSW students’ learning from the project is discussed in the context of CSWE’s 2015 EPAS competencies. Participation in the experiential/service-learning project supported the ability of the MSW students to build a sense of themselves as professionals bringing value to the community, enhanced their understanding of cultural diversity and family engagement, and provided context for vulnerable students’ struggles in school and the families’ difficulties with school engagement. This project illustrates the potential of school-university partnerships involving MSW field students to help bridge the gaps in school-family partnerships, particularly in diverse and low-income communities, and highlights areas where different teaching methods can be used to reinforce competencies learned.
Finding “Health” and “Meaning” in Texas-Sized Turnover: Application of Seminal Management Principles for Administration and Research in U.S. Public Child Welfare Agencies
Authors: Willis Nicole , Chavkin Nancy , Leung Patrick
Published: January 2017

Public child welfare agencies in the United States have struggled with high turnover rates, especially among caseworkers. Research has explored turnover in terms of negative organizational outcomes, and efforts have been developed to reduce overall turnover rates. However, there has been little change in turnover rates in the last 30 years. The public child welfare system is inclined to higher turnover due to the unique nature of the work. Efforts to reduce the overall turnover rate fail to recognize the heterogeneity and healthy aspects of turnover unique to public child welfare organizations, which present challenges for both practice and research. By critically questioning how turnover is socially constructed, measured, and addressed, and integrating seminal management principles, a more meaningful metric can be developed. These challenges are explored, and recommendations are proposed for administration and research that include reconstructing and applying a new perspective on turnover to inform and evaluate initiatives that can reduce the impact of dysfunctional turnover within public child welfare organizations.
Influence of Victim and Perpetrators’ Alcohol Use on Social Work Student’s Levels of Rape Myth Acceptance
Authors: Baldwin-White Adrienne , Elias-Lambert Nada
Published: January 2017

Rape myths are stereotyped, false cultural values that serve to justify sexual assault against women. This study examined the perceptions of alcohol use on levels of rape myth acceptance among social work students. One hundred and ninety-five bachelor's and master's students were randomly assigned to read a vignette developed by researchers depicting a date rape with the victim, perpetrator, both, or neither consuming alcohol. Results of a descriptive analysis showed that students are willing to accept certain rape-supportive beliefs, but not others. Participant responses to rape myths differed based on the particular vignette the respondent was assigned to read. Further research is needed to examine the particular myths social work students endorse and the situational factors that influence those endorsements. Social work students must be educated about how endorsements of rape myths can affect their interaction with survivors and perpetrators.
Organizational Identification: Perspectives of Dispersed Social Workers
Authors: Allen Milton Sharlene A. , Sinclair Michael M. , Vakalahi Halaevalu Ofahengaue
Published: January 2017

Human service organizations are often challenged to become more efficient while maintaining the quality of their services. As a result, more organizations have restructured, adopting the practice of dispersed work, which allows employees more freedom and flexibility to meet organizational goals outside of the traditional workplace. While dispersed work allows social workers to engage in work activities beyond the traditional office environment, it may also impact their sense of belonging to the organization. Eleven dispersed social workers were interviewed to understand how interaction via new communication technology impacts organizational identification. Overall themes gleaned from this study suggest that although dispersed social workers perceive themselves as having more autonomy and flexibility, they also can feel socially isolated and disconnected from their peers and supervisors, which may negatively impact organizational identification. Despite the enhanced efficiency that technology can bring, human service organizations must strive to understand the unintended consequences of a dispersed workforce.
Understanding Everyday Relationship Work: The Development of a Relationship Maintenance Scale
Authors: Chonody Jill M. , Killian Mike , Gabb Jacqui , Dunk-West Priscilla
Published: January 2017

Relationship maintenance behaviors contribute to the longevity of intimate relationships, yet existing scales are limited. Available measurement tools are primarily constrained to the Relationship Maintenance Strategy Measure (RMSM) and its further revisions. Covering a number of domains, conceptual overlap with other aspects of an intimate relationship (e.g., household division of labor) may exist. Our cross-sectional exploratory study included participants from 60 countries (n=8,162) who completed an online survey. Participants were diverse in their relationship status, age, sexual orientation, and race/ethnicity. From their responses, we developed a parsimonious and brief measure of relationship maintenance (8 items) through exploratory and then confirmatory factor analyses. Results indicated that the Relationship Maintenance Scale (RMS) shows initial evidence of reliability and validity. The RMS may have utility in working with couples and families. Future research should seek to re-test its use with varied samples, such as couples seeking relationship support.
Graduating MSW Students’ Recommended Interventions for Teen Dating Violence: A Descriptive Analysis
Authors: Rueda Heidi Adams , Hawley Alicia , Black Beverly M. , Ombayo Bernadette
Published: January 2017

Teen dating violence (TDV) is a widespread issue that social workers are likely to encounter in their practice with youth, yet little research exists concerning their preparedness to do so. This study assessed the proposed interventions of graduating MSW students (n=73) from two accredited universities in response to two scenarios of TDV. Each scenario reflected various forms of relational violence. Nearly one-third of students’ proposed interventions focused on the need to deliver some form of education, healthy relationships being the most prevalent theme. Other interventions included teaching about appropriate boundaries, issues of control and anger, self-esteem-building, and communication skills. The second most common set of responses pertained to individual assessment, and the third to individual and couple’s counseling. Few comments identified specific TDV interventions, such as safety planning or evidence-based prevention programs. Students’ recommendations for education and counseling rather than safety planning or multi-level interventions indicate that social work programs need to provide specific content in MSW curricula related to TDV and evidence-based interventions.

Authors: Nigeen Waseeqa , Farooq Mariya , Afzal Asima , Ashraf Sameena , Bhat Abdus Sami
Published: January 2017

Background: Postpartum haemorrhage (PPH) is a very common complication that follows delivery. It is one of the leading causes of maternal mortality both in developing and developed countries. Primary PPH has been studied a lot, but data regarding secondary PPH is sparse. Our objective was to study the clinical characteristics and outcome of patients presenting with secondary PPHMethods: A retrospective descriptive study done at Lalla Ded hospital Srinagar, a tertiary care hospital of North India, between June 2015 and December 2015.Results: Fifty patients with secondary PPH were studied out of whom 36 were delivered outside this hospital and referred. Fourteen patients who delivered in this hospital developed secondary PPH. Mean age of patients was 35±3 years. Retained products of contraception (RPOCs) was the leading cause in 36 (72%) of patients followed by endometritis in ten (20%). Mean hemoglobin concentration was 8.7±1.9grams ranging from 4.4 grams to 12.9 grams. Mean hospital stay was 6.3±1.5 days ranging from 1 day to 20 days. Curettage was done in 40 (80%) of patients including 36 having RPOC s and check curettage in four patients. Fourteen (28%) patients required blood transfusion. One patient required hysterectomy. None of the patients died.Conclusions: Secondary PPH has been studied very little. Our results show retained products of contraception as a leading cause of secondary PPH which is probably related to poor management of third stage of labour. There is crucial role of active management of third stage of labour in preventing secondary PPH. Majority of secondary PPH patients require dilatation and curettage with other supportive measures only. Surgical intervention is rarely required. Blood loss is usually mild to moderate. Prognosis is good if medical intervention is sought early.

Authors: Srivastava Shubha , Chandra Madhuri
Published: January 2017

Background: The doctors of The Obstetric and Gynecological Society of Bhopal and the department of Obstetrics and Gynecology, Gandhi Medical College, Bhopal have been imparting Family Life Education to school girls and aganwadis as part of their school health program. This project was designed to evaluate the effect of school health programs and to gain an insight into the perceptions of the school girls regarding menstruation, hygiene, nutrition, marriage and the program.Methods: The study was conducted in five schools in which 537 girls participated. A questionnaire was provided to the school girls to know their knowledge and perception regarding menstruation, reproduction, nutrition and their views on the quality and usefulness of the Family life skills sessions.Results: The study showed that most of the girls gained information about menstruation from their mothers. Menstruation is still considered as something shameful and young girls face many restrictions. Knowledge regarding menstruation, reproduction, contraception and diet is still lacking among the school girls. Family life skill sessions address these issues very effectively. Most of the girls enjoyed the sessions and were ready for more.Conclusions: The Family Life sessions provide age appropriate, uniform skilled advice on nutrition, prevention of anemia, hygiene (menstrual), problems of growing years, career counseling, safe sex, contraception, teenage pregnancy and exclusive breastfeeding. Imparting family life skills to school girls provides a welcome platform for them to interact with doctors and counsellors, increasing their knowledge on health issues like menstruation, hygiene and nutrition.

Authors: Agarwal Mukta , Samanta Sutapan , Bhusan Divendu , Anant Monika
Published: January 2017

Background: Unregulated fertility not only disrupts the health of women and child but also disrupts the economy of society and nation. To gain the knowledge about awareness and contraceptive practices in women living in semi-urban area, a cross-sectional study was conducted over one year to evaluate the awareness, acceptance and prevalence of contraceptive methods and various factors affecting the contraceptive usage.Methods: It was a cross sectional study conducted in outpatient department of obstetrics and gynaecology, in a tertiary medical college hospital. The study constituted 300 subjects. It was an interview based study. Data were collected on age, parity, literacy level, residence, knowledge about various contraception, women practicing contraception and reasons for non-use of contraceptives.Results: A total of 300 women in the age group between 18-45 years were studied. It was observed that most of the women belong to the age group of 25 to 34 years (45.33%). 70% belong to rural population. only 20% were para 2 or less.35.33% of the study population were illiterate and 21.67% had education above secondary level. 290 (96.67%) women were aware of one or multiple methods of contraception however, 126 (42%) women accepted the contraceptive practices. Of 300 women, 94 (31.33%) followed permanent methods of contraception. 66% of the study population had experienced unwanted pregnancy and among them 44% pregnancies were aborted. Number of women practicing contraception was very low, i.e. 42% and the main reason of nonpractice of contraception was family pressure mainly in laws, husband gender bias, physical abuse, etc.Conclusions: It was noted that though knowledge of at least one method of contraception was wide among the women but still actual practice was very low. More programs are required to combat the influence of various factors on contraception usage, and emphasizing on the positive effects of the use of contraception.
Endometriosis: an enigmatic disease with many faces

Published: January 2017

Endometriosis is a benign disease defined by the presence of the endometrial glands and stroma outside of the uterus, both at pelvic and extra pelvic sites. We are reporting 4 unusual cases of endometriosis that are unique on their own due to site of endometriosis, presenting symptoms, complications and treatment. Endometriosis was present at post caesarean scar site in one case, at vault site in another case, in bladder in third case and in the last case it caused frozen pelvis with hydroureter, hydronephrosis and possibly infertility. All four patients have been treated laparoscopically and have been following up with no recurrence of its symptoms. The purpose of this article is to create awareness among Doctors about endometriosis, which is more common than previously thought as. Endometriosis has been rightly summed up in the phrase “The clock is definitely ticking, as we know millions of women still live lives awash in anguish, just as they did thousands of years ago and just as they will centuries from now unless we steer ourselves faster toward the long-elusive cure. Four thousand years is long enough; the time has come to end the empire of endometriosis”.

Published: January 2017

Spontaneous adrenal hemorrhage of pregnancy is an acute hemorrhage into the adrenal gland in pregnancy in the absence of trauma, tumor or decoagulant therapy. This can have catastrophic consequences on the mother and the baby and if the hemorrhage involves both the adrenal glands the risk is aggravated because of the high incidence of resulting adrenal insufficiency. We report a case of spontaneous bilateral adrenal hemorrhage in pregnancy resulting in adrenal crisis. A 26 year old primigravida presented at 32 weeks of gestation initially with right sided infrascapular pain and one month later with similar pain in the left side associated with high blood pressure. Imaging with ultrasound and MRI was suggestive of bilateral adrenal mass probably hemorrhage; 2 days following the second episode of pain she developed drowsiness and hypotension and a diagnosis of primary adrenal insufficiency was confirmed by a low serum cortisol and high ACTH. She stabilized with hydrocortisone therapy and the fetus was closely monitored. At 37 weeks she had a normal vaginal delivery under steroid cover. Repeat MRI abdomen 3 months after delivery showed resolution of the hemorrhage but biochemically she continued to be cortisol insufficient at 1 year of follow up. Prompt diagnosis of adrenal hemorrhage in pregnancy and treatment of adrenal insufficiency along with close fetal monitoring usually results in good perinatal outcome in spontaneous adrenal hemorrhage of pregnancy.

Defining Procedural Distress in the NICU and What Can Be Done About It
Authors: Schiavenato Martin , Holsti Liisa
Published: January 2017

Abstract

Procedural distress is a common occurrence in the NICU and is tied to attempts to support the life and development of vulnerable premature infants. We discuss the epidemiology of procedural distress and the potential negative consequences on infant neurodevelopment. We define procedural distress in the NICU and outline three approaches to limit or to reduce its detrimental effects including minimizing the number of procedures, instituting measures for developmentally supportive care, and using preemptively pharmacologic and nonpharmacologic analgesia. Despite the pervasiveness of procedural distress in the NICU, clinical and administrative measures are available to ameliorate possible harmful outcomes.
An Acceptance and Commitment Therapy Approach for Partner Aggression
Authors: Zarling Amie , Berta Meg
Published: January 2017

Partner aggression is a major public health concern. Batterers’ intervention programs (BIPs) are commonly used as an alternative to incarceration for offenders who have been arrested for domestic assault. Historically, BIPs have shown little effectiveness in reducing partner aggression. This article presents a new BIP based on acceptance and commitment therapy (ACT; Hayes, Strosahl, & Wilson, 1999). ACT is a third-wave therapy that builds on the cognitive-behavioral tradition, focusing on increasing psychological flexibility by promoting acceptance and mindfulness processes. Several lines of evidence support the use of ACT in the treatment of partner aggression. Achieving Change Through Values-Based Behavior (ACTV; Lawrence, Langer Zarling, & Orengo-Aguayo, 2014) was developed based on ACT principles with a specific focus on feasibility and transferability to the community correctional setting and court-adjudicated treatment. ACTV incorporates experiential skills training and uses innovative methods to engage participants and teach the ACT processes. This article details the components of ACTV, including a case study to illustrate one participant’s journey through the program. We also present preliminary pilot data, which look promising with respect to reductions in domestic assault and violent recidivism.

Published: January 2017

The principal purpose of this investigation is to study the effect of robotic cooperative learning methodologies on middle school students’ critical thinking, and STEM interest. The semi-experimental inquiry consisted of ninety four six-grade students (forty nine students in the experimental group, forty five students in the control group), chosen by their principals. A critical thinking test was administered to evaluate the cognitive skills and STEM interest of the students. Instruction was implemented in two formats: cooperative learning and problem-based learning. The experimental group utilized robotic cooperative learning while the control group utilized problem-based learning.  After four sessions of both instruction types with both groups the findings reveal that critical thinking of students is enhanced significantly by robotic cooperative learning (P<0.01).

Electromagnetic Imaging

A series of images that look like yellow lumps on a line are the first-ever images of the area around the wellbore where fractures have been propped open using specially coated proppant stimulated by electromagnetic (EM) energy.

The images created by Carbo Ceramics could represent a milestone on the journey to find an answer to a critical question facing unconventional producers— how much rock is being stimulated and propped with grains of sand or ceramic for maximum production?

“People see the value in this area; they are starved for this,” said Terry Palisch, global engineering adviser for Carbo, who described what is seen in the images as the propped reservoir volume.

Four groups of researchers are seeking a direct way to visualize what is left behind after fracturing. Three of the projects involve getting images by using proppant specially treated to be visible when stimulated by EM energy.

Microseismic images currently used in the industry to show fracturing results are based on the popping sounds of rocks rubbing against each other, like fingers snapping, but not the quiet, productive work of opening fractures and pumping in proppant to ensure they stay open.

“Microseismic doesn’t really tell us where the proppant has gone. It shows where failure events are occurring,” said Mukul Sharma, a petroleum engineering professor at the University of Texas (UT) at Austin. He heads the Hydraulic Fracturing and Sand Control Joint Industry Project (UT Fracturing JIP) at UT, which is leading one of the projects mentioned earlier. “What matters is where the proppant is. In many rocks, the propped part of the fracture is the primary contributor to well productivity. That is the main advantage of electromagnetic (visualization) over microseismic.”

Imaging the area that has propped fractures is a starting point for multiple investigations into how to efficiently extract more than 10% of the oil in unconventional plays. It can define the length and height of propped fractures, offer more accurate measures of the productive rock for modeling, and tell engineers how to space wells to effectively stimulate the reservoir without hitting nearby wells.
Pressure Changes While Fracturing Add to Marcellus Well Production

Marcellus Well Production

When it comes to hydraulic fracturing, steadiness may not be a virtue. That was the conclusion of a test to see if rapid pump rate variations would lead to greater production than conventionally fractured stages when the pressure was held steady.

The stages in which rapid pump variations were used to create pressure pulses produced an average of 18% more gas than the ones with steady pumping pressure, said Jordan Ciezobka, manager of research and development for the Gas Technology Institute (GTI), which did the test in the Marcellus with WPX Energy. The project was funded by the Research Partnership to Secure Energy for America (RPSEA).

Based on early results, this simple method may “increase production with no change in the water or sand pumped,” he said during a presentation at the recent SPE Hydraulic Fracturing Technology Conference.

Since then, a version of the method with “more aggressive rate changes engineered specifically to accommodate the completion design in the Permian Basin” has been tested at a site where it was monitored using microseismic, production logging, and radioactive tracers. Ciezobka said results from that test are expected soon.

The idea grew out of previous well monitoring research work in which microseismic testing detected a surge in seismic activity—an indication of more fracturing—whenever the pump speed had to be adjusted for operational reasons.

Where that happened during fracturing, the well’s output was greater, Ciezobka said. So the thinking was, “Why not redesign the frac pump rate to get higher microseismic activity and get more production?,” he said.

To test the theory, GTI set up a test where it used a variable pumping rate on 14 odd-numbered stages, and a steady rate on 13 even ones. The pump rate variations were done during the pad period, prior to pumping proppant. In a future test they plan to also vary the pressure while pumping proppant.

Other than the rapid pump rate changes, which required some practice by the crew to get it right, the odd- and even-numbered stages showed no differences.

But on average, the stages where the pumping rate varied produced 65.4 Mscf/D of gas, compared with 55.5 Mscf/D when the rate was constant, the paper said. The six highest production rates resulted from stages in which the pressure was varied.

When production from the test well was compared to a nearby well that had been conventionally fractured with 50% more proppant, the variable rate well’s production had declined at a lesser rate.

Another difference was surface treating pressure, which is an indication of the force required to pump fluid into the formation, which was lower when the pump pressure was varied. Analysis of the pressure decline rate after the pumps were shut down (water hammer diagnostic) indicated variable rate stages created, broader, more complex fractures, he said. JPT
EOR-For-Shale Ideas to Boost Output Gain Traction

Low oil prices may not be the biggest threat to the long-term sustainability of the North American shale business.

Some are more concerned about the low recovery rates of horizontal shale wells, estimated to be about 7% on average— far short of the 40% achieved through primary and secondary (waterflooding) production in conventional reservoirs.

Refracturing has been touted as the next big thing to improve ultimate recovery, but such operations remain relatively expensive and may only temporarily reset production to initial rates once or twice in a well’s life.

To see long-term results and a doubling or tripling of current recovery rates, a number of experts say enhanced oil recovery (EOR) technologies must be developed to work in tight shale reservoirs. And due to persistently low natural gas prices, current efforts appear to be exclusively focused on oil and condensate producing wells.

It is early days for this area of EOR research. There is no consensus on which approaches will work best, how much they may cost, what the most pressing challenges are, or exactly when an EOR operation should begin.

“Our understanding is really small,” said Todd Hoffman, an assistant professor of petroleum engineering at Montana Tech University. “We’re coming from the conventional world where ‘this’ is how we did EOR and we may just have to throw all that out.”

Hoffman is one of several researchers trying to figure out how EOR methodologies can be adapted or reinvented for the oil-rich shale fields of North Dakota, Texas, and Canada.

One of the most popular ideas being studied is a huff-and-puff approach that uses a single horizontal well to alternate between producing oil and injecting natural gas or CO2 to re-pressurize the reservoir and displace oil.

Another idea is to apply continuous injections into one well and use an offset well as the producer. Others are looking into flooding the wells with surfactants and possibly acid to stimulate production.

In May, EOG Resources laid claim to the first economic demonstration of an injection-based EOR technology for tight oil in the US. The company said the development may have long-term production benefits and is competitive with drilling new wells.

But other than making it clear that the process has been successful and uses dry gas produced in the same field, EOG is withholding key operational details such as whether it involves the huff-and-puff technique or continuous injections.

A number of other innovative shale producers including Statoil, Nexen Energy, Continental Resources, and Marathon Oil have also either funded research or are known to be running pilots, but have not made their results public.

As most shale producers remain silent about their EOR efforts, there are a growing number of technical papers being published by university petroleum departments and reservoir engineering consultants. They are using computer models and corefloods to test their theories and have produced promising numbers that suggest there may be several practical ways to implement EOR strategies for shale.
