Abstract Cementing in wellbores with low fracture gradients can be challenging due to the risk of formation breakdowns when exceeding maximum allowable equivalent circulation densities (ECDs). Consequences include severe losses and formation damage, and insufficient placement of the cement slurry that necessitates time-consuming and costly remedial cementing to ensure zonal isolation. In recent cementing operations in Spain, the formation integrity test (FIT) of the open hole section indicated that the formation would have been broken down and losses occurred based on calculated equivalent circulating densities (ECDs) if the cement slurry had been pumped in a single-stage to achieve the operator's top-of-cement goal. As a solution to this problem, cementing was performed in stages, using specialty tools. However, during these operations, the stage tool did not work properly, wasting rig time and resulting in unsuccessful cement placement. To overcome this issue, the operator decided to cement the section in a single stage, preceded by a novel aqueous spacer system that aids in strengthening weak formations and controlling circulation losses. Before the operation, laboratory testing was conducted to ensure the spacer system's performance in weak, porous formations and better understand its mechanism. This paper will outline the laboratory testing, modeling and engineering design that preceded this successful single stage cementing job in a horizontal wellbore, with a final ECD calculated to be 0.12 g/cm3 (1.00 lb/gal) higher than the FIT-estimated figure.

Pure Tone Audiogram

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.

Ultimate Purpose

Purpose The purpose of this article is to present a client-centered model of counseling that integrates information and personal adjustment counseling. Research has indicated that audiologists are more comfortable with counseling that is information based than with personal adjustment counseling. The prevailing model of diagnosis appears to be the medical model in which, first, a case history is taken, then testing and, finally, counseling. This model lends itself to audiologist as expert and the counseling as a separate entity based on information and advice. Further research has indicated parents retain little of the information provided in the initial examination because of their heightened emotions. This article presents a client-centered model of diagnosis in which information is provided within an emotionally safe context, enabling the parents to express their feelings and have the ability to control the flow of information. The ultimate purpose of a client-centered model is to empower parents by making them active participants in the diagnostic process rather than passive recipients. Conclusion The client-centered model has wide implications for the diagnostic process as well as for the training of students.

Purpose The purpose of this study was to ascertain the extent to which school-based speech-language pathologists' (SLPs) assessment practices with individual English learners (ELs) align with federal legislation and professional practice guidelines. Specifically, we were interested in examining SLPs' use of multiple tools during individual EL assessments, as well as relationships between practices and number of types of training experiences. Method School-based SLPs in a Midwestern state were recruited in person or via e-mail to complete an online survey pertaining to assessment. Of the 562 respondents who completed the survey, 222 (39.5%) indicated past or present experience with ELs, and thus, their data were included in the analyses. The questionnaire solicited information about respondent's demographics, caseload composition, perceived knowledge and skills and training experiences pertaining to working with ELs (e.g., graduate school, self-teaching, professional conferences), and assessment practices used in schools. Results The majority of respondents reported using multiple tools rather than a single tool with each EL they assess. Case history and observation were tools used often or always by the largest number of participants. SLPs who used multiple tools reported using both direct (e.g., standardized tests, dynamic assessment) and indirect tools (e.g., case history, interviews). Analyses revealed low to moderate positive associations between tools, as well as the use of speech-language samples and number of types of training experiences. Conclusions School-based SLPs in the current study reported using EL assessment practices that comply with federal legislation and professional practice guidelines for EL assessment. These results enhance our understanding of school-based SLPs' assessment practices with ELs and may be indicative of a positive shift toward evidence-based practice.

Holistic Assessment

Purpose Children with a cleft palate (± cleft lip; CP±L) can have difficulties communicating and participating in daily life, yet speech-language pathologists typically focus on speech production during routine assessments. The International Classification of Functioning, Disability and Health: Children and Youth Version (ICF-CY; World Health Organization, 2007 ) provides a framework for holistic assessment. This tutorial describes holistic assessment of children with CP±L illustrated by data collected from a nonclinical sample of seven 2- to 3-year-old children, 13 parents, and 12 significant others (e.g., educators and grandparents). Method Data were collected during visits to participants' homes and early childhood education and care centers. Assessment tools applicable to domains of the ICF-CY were used to collect and analyze data. Child participants' Body Functions including speech, language, and cognitive development were assessed using screening and standardized assessments. Participants' Body Structures were assessed via oral motor examination, case history questionnaires, and observation. Participants' Activities and Participation as well as Environmental and Personal Factors were examined through case history questionnaires, interviews with significant others, parent report measures, and observations. Results Valuable insights can be gained from undertaking holistic speech-language pathology assessments with children with CP±L. Using multiple tools allowed for triangulation of data and privileging different viewpoints, to better understand the children and their contexts. Several children demonstrated speech error patterns outside of what are considered cleft speech characteristics, which underscores the importance of a broader assessment. Conclusion Speech-language pathologists can consider incorporating evaluation of all components and contextual factors of the ICF-CY when assessing and working with young children with CP±L to inform intervention and management practices.
