Authors: Ayosanmi Oluwasola Stephen , Oden Lorette , Ayosanmi Titilope , Alli Babatunde , Wen Mei , Johnson Jamie 
Published: March 2020

Objectives:
We sought to determine how the Health Belief Model (HBM) constructs relate to Human Immunodeficiency Virus (HIV) screening decisions among international students and which of the HBM constructs was most relevant in those screening decisions.

Methods:
We conducted a cross-sectional pilot study using an online survey of international students at Western Illinois University in the United States. Participants signed electronic informed consent. The online survey comprised of questions that assessed their sociodemographic characteristics, acceptance of HIV screening, and perceived knowledge of HIV. The survey also determined the role of perceived benefits, perceived threat, and cues to action in making HIV screening decisions among the study population.

Results:
Four hundred and ninety students were invited to participate in the survey out of which 185 responses were obtained. In all, 107(57.8%) were males, and 78(42.8%) were females. Most of the respondents were from Asia (64.9%) and Africa (24.9%). The prevalence of acceptance of HIV screening among international students was found to be 73.5%. About 90% of the participants perceived HIV screening to be beneficial to their health, and 76% of them would accept the screening because they were offered. The majority (83%) of participants who said that they would not accept HIV screening, were also not sexually active, and they did not think they could be susceptible to HIV

Conclusion and Implications for Translation:
Perceived benefits and cues to action were found to be the significant factors that informed the decision of people who accepted to be screened for HIV Perceived susceptibility informed the decision of those that rejected the screening. Caution is warranted in generalizing the findings from this study because of the limited sample size; however, we are confident that our findings are reproducible in a larger population context.

Published: March 2020

Abstract
The demand for well plug and abandonment (P&A) operations in Brazil has increased significantly during the last 3 years, resulting in a steep learning curve that can lead to development of state-of-the-art methodologies that save time, reduce operational risks, and provide reliable cost-effective solutions.
This paper presents a comprehensive analysis of recent well abandonment operations in a mature field in Brazil, which included wells that were depleted or no longer economically viable. A methodology is discussed and highlights the use of a casing collar locator (CCL) to perform depth correlation before setting packers and placing cement plugs, real-time pressure signals to monitor packer setting, and coiled tubing (CT) internal and external pressure management to help ensure that all cement is pumped out of the CT.
Using Simultaneous Services to Provide Operational Efficiency Gains and Reduce Operational Costs for Coiled Tubing/ Fiber Diagnostic Services
Authors: Butz Stephen , Williams Troy , McCarthy Caitlin 
Published: March 2020

Abstract
A case study is presented on increasing operational efficiencies using fiber optic-equipped coiled tubing to perform distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) in conjunction with millout operations. In unconventionals with plug-and-perf or sliding-sleeve completions, hydraulic workover or coiled tubing is deployed to millout and clean the wellbore to total depth (TD) before the well can be put on production. Traditionally, the millout and cleanout process is a standalone operation. In the event a diagnostic service is performed on the well, a workover rig, coiled tubing unit, or wireline would be deployed in a second intervention after the initial millout is performed. This method presents a challenge to operators who want to bring wells online in a timely and economical manner.
By combining the millout and diagnostic cababilities into a single operation, operational efficiencies were significantly increased for the operator. Operators were able to minimize exposure to in-well operations and reduce the number of interventions necessary to bring a single well online. This resulted in a reduction of well shut-in time and faster data turnaround time on diagnostic evaluation. Simultaneous milling and diagnostic services were completed on 31 wells throughout 2018. Plug/Sleeve/Sand millouts were performed to well TD with a fiber-optic capable coil-tubing unit. Then the same work string was used to gather diagnostic data on the entire completion interval during the same run. These diagnostic data were collected and provided to the operator in an effort to better understand the completion design and hydraulic fracture placement. The operational efficiency gained by deploying diagnostic services in conjunction with the millout services lowered the operator's operation costs by USD 100,000 and operations time by 36 hr on average.

Abstract
Increasing water cut and well integrity are currently major concerns, particularly in mature fields. Excessive water production can detrimentally affect the profitability of hydrocarbon-producing wells if not controlled properly. This paper describes a successful zonal isolation case study in a dual-string completion well with well integrity challenges and variable permeability intervals using a modified organically crosslinked polymer (m-OCP) and coiled tubing (CT)-assisted real-time temperature sensing for effective placement and post-operation evaluation.
The m-OCP system is a combination of a thermally activated, organically crosslinked polymer and particulate material for leakoff control to help ensure shallow matrix penetration. It is acid resistant, H2S tolerant, has controlled penetration, and is easy to clean up using a rotating wash nozzle. The setting time can be accurately predicted with simple laboratory tests. These characteristics make this system the preferred choice compared to the traditional cement squeeze method that is both time consuming and exorbitant. Diagnostic services delivered by CT-conveyed fiber-optic distributed temperature sensing (DTS) that add real-time capabilities to monitor well integrity assess reservoir performance and visualize treatment efficiency. Using real-time diagnostic services, tubing integrity was confirmed, and the treatment was placed in the same run, helping eliminate the possibility of an undesired leakoff. After allowing the setting time, a successful pressure test or post-cleanout DTS (in case pressure test is not feasible) was used to establish the reliability of this method.
The first attempt was made on Well A of the field; however, isolation was successful using m-OCP and conventional CT. Operation execution and production recovery took more time than planned because of the uncertainty concerning well integrity in the dual-string completion and lost circulation in the depleted reservoir, which affected the economic deliverability of the operation. The major challenges with Well B of the same type in the same field remain the same. Thus, as part of lessons learned from the previous intervention, diagnostic services were chosen for a real-time evaluation of the completion to review well integrity and accurately place the optimized treatment, thereby helping improve overall results in the most time-saving and lucrative manner.
The successful isolation of the water-producing zone/perforations in the southeast Kuwait field using m-OCP and CT-assisted real-time DTS to review well integrity can be considered a best practice for addressing similar challenges globally.
Be Dynamic! Job Planning for Coiled Tubing Conveyed Extended Reach Pulsation Tools
Authors: Newman Ken , Kelleher Patrick 
Published: March 2020

Abstract
In recent years there have been a significant number of coiled tubing (CT) failures during frac-plug drill-out operations. These failures occur most often when an axial vibration/pulsation extended reach tool (ERT) is included in the bottom hole assembly (BHA). There are significant efforts in the industry to first understand and then mitigate these failures. This paper examines the dynamic axial vibrations caused by these tools, and how these vibrations are amplified in the wellbore, possibly causing the material damage that later causes the failures. In some cases, these amplified vibrations have damaged surface equipment.
Foam Stability - Does Well Inclination Matter?

Abstract
To minimize fluid loss and the associated formation damage, underbalanced coiled tubing (CT) is one of the preferred methods to perform cleanout operations and re-establish communication with an open completion interval. Because of their high viscosity and structure, stable foams are suitable cleanout fluid when underbalanced CT operations are applied. However, unstable foams do not possess high viscosity and as a result, they are poor in cleanout operations, especially in inclined wellbores. This study is aimed to investigate the effects of wellbore inclination on the stability of foams.
In this study, foam drainage experiments were carried out using a flow loop that has foam drainage measurement section and pipe viscometers. To verify proper foam generation and validate the accuracy of measurements, foam rheology was measured using pipe viscometers. Drainage experiments were performed with aqueous, polymer-based, and oil-based foams in concentric annulus and pipe under pressurized conditions. Tests were also conducted at an inclined orientation to examine the effect of wellbore inclination on the stability of foams. The foam bubble structure was examined and monitored in real-time using a microscopic camera to study bubble coarsening. The foam quality (i.e. gas volume fraction) was varied from 40 to 80%.
The drainage rate was slightly higher in the pipe section than in the annulus. More importantly, the drainage rate of foam in an inclined configuration was significantly higher than that observed in a vertical orientation. The inclination exacerbated foam drainage and instability substantially. The mechanisms of foam drainage are different in inclined configuration. In inclined wellbores, drainage occurs not only axially but also laterally. As a result, the drained liquid quickly reaches a wellbore wall before reaching the bottom of the hole. Then, a layer of liquid forms on the low-side of the wellbore. The liquid layer flows downward due to gravity and reaches the bottom of the hole without facing major hydraulic resistance of the foam network. This phenomenon enhances the drainage process considerably.
Although foam drainage experiments are reported in published literature, there is limited information on the effects of geometry and inclination on foam drainage and stability. The information provided in this article helps to account for the impact of inclination on foam stability to improve its CT cleanout performance in directional wells.

Abstract
The Aguada Pichana Gas field is located in the center of the prolific Neuquén Basin, in Argentina. It produces gas and condensate through monobore completions. Since 2006, an increase in liquid loading has become an issue in current wells conditions, resulting in the need of reducing production tubing size to enable stable gas production for continuous liquid removal. Following analysis, the appropriate solution resulted in running a velocity string (VS) as an effective means for liquid removal at current and future production conditions. The challenge was to find a hanger system, which would allow, without killing the well, to hang a 2.0-in[CSH1] CT VS. Additionally, the hanger should facilitate unloading the well by circulating nitrogen and restore the production rate without the need to recover the VS.
After a field trial, the first phase of the campaign has been completed with the introducion of a special designed fluted seal and retrievable CT VS hanger system (quantity: 20 jobs), and second phase of campaign (quantity: 60 jobs) with a low cost and locally manufactured reliable system. The paper describes the operational planning, different hanger systems, deployment methods and lessons learned after more than 80 jobs.

Published: March 2020

Abstract
The initial proposal for abandoning a subsea field in the North Sea was to carry out the pre-abandonment work from the Light Well Intervention Vessel (LWIV) followed by the complete Plug and Abandon (P&A) operation conducted by a Mobile Offshore Drilling Unit (MODU). During the detailed design of the workscope, the four wells in the field were identified as through-tubing abandonment (TTA) candidates. To maximise the use of the LWIV and optimise the MODU sequence these TTA operations were planned to be executed from the LWIV. The TTA cement plug is installed by circulating cement down the production tubing and taking returns from the annulus to place the cement plug above the production packer and deep-set plug. An agitator tool is installed in the production tubing to improve the cement coverage in the annulus. As the LWIV does not have a permanently installed cementing system, a temporary system was fitted on the vessel which proved to be challenging given the deck limitations of the installation. Two of the four TTA candidate wells included a downhole gauge cable in the completion design across the zone that was required to be cemented. To ensure the long-term integrity of the TTA cement plug with the gauge cable, an expanding self-healing cement was utilised.

Published: March 2020

Abstract
Background : The Ethiopian health system has been facing challenge to meet the growing desire for family planning service. Shortage of trained service providers at a primary care setting is one of the reasons for unmet need to access Long-Acting Reversible Contraceptives (LARCs). To investigate feasibility of task shifting of providing LARCs, community health extension workers (CHEWs) were trained in four Regions of Ethiopia on how to insert and remove contraceptive of implant and Intrauterine Contraceptive Device (IUCD). Therefore, this study is aimed at assessing the knowledge, attitude and skill of the trained health extension workers to provide LARC. Methods : A cross sectional study was employed from April to May 2017 in four feasibility study regions of Ethiopia, namely; Amhara, Oromia, Tigray, and Southern Nation, Nationalities and Peoples Region (SNNPR). Data were collected from 66 health extensions who give the service of 402 IUCD and 793 implants. The collected quantitative data were analyzed using statistical package for social science (SPSS) version 25.0 for window. Results : Nearly two-third (62.7%) of L4HEWs had good level of knowledge of counseling for LARC. Using anatomical model L4HEWs completely performed all steps for around 58.5% Implanon, 30.6% Jadelle and 22% IUCD insertions. Conclusions : With adequate training and supportive supervision, L4HEWs can provide high-quality implant insertions. The IUCD insertion and removal needs careful consideration. Despite the possibility of improving uptake of LARC services by training more L4HEWs, there is a need to improve the skill of IUCD insertion and removal before scale up the intended task sharing.

Abstract
Background

A high rate of metal-on-metal total hip arthroplasty (MoM-THA) has been well-known. The aim of this study was to compare the long-term outcomes of patients who had undergone uncemented or cemented THA(UTHA or CTHA) following initial MoM-THA failure.

Methods

Data from 234 patients (234 hips) who were treated with UTHA or CTHA following initial MoM-THA failure during 2007 - 2018 were retrospectively compared. Follow-up occurred 3 months, 6 months, 1 year, 2 years, and then every 1 year after conversion. The mean follow-up was 84.15 months (67 - 101 months). The primary endpoint was the Harris Hip Scores (HHS); secondary endpoint was the incidence of major orthopaedic complications.

Results

The HHS demonstrated statistically greater differences in Group CTHA than in Group UTHA 12 months after conversion. From the 12th month after conversion to the final follow-up, CTHA yielded superior functional outcomes than UTHA. Between-group noteworthy differences were observed regarding the rates of re-revision, aseptic loosening, and periprosthetic fracture (10.3% for UTHA vs 2.5% for CTHA, p = 0.015; 16.3% for UTHA vs 5.9% for CTHA, p = 0.011; and 12.0% for UTHA vs 4.2% for CTHA, p = 0.045, respectively).

Conclusion

In the setting of revision following initial MoM-THA failure, we found definite evidence of the superiority of CTHA over UTHA in regard to improving functional outcomes and decreasing the incidence of major orthopaedic complications.

Published: March 2020

Abstract
Cognitive radio is an essential technology to overcome fixed spectrum allocation problems and improve its use through dynamic spectrum access techniques. Spectral decision-making is a function of the cognitive cycle that aims to choose the best spectral alternative among a set of finite possibilities. An inadequate process of decision-making can significantly affect the network parameters. Therefore, it is important to determine the best strategy and if this decision making should be collaborative. The present research analyzes the performance of failed handoff rate according to the amount of information shared between secondary users. The aforementioned information corresponds to the spectral occupancy for the GSM frequency band, that is characterized by a set of users and five levels of collaboration, 10%, 20%, 50%, 80% and 100%, where each level represents the percentage of users are part of the training model implemented. The decision-making process is carried out by using two multi-criteria techniques: Feedback Fuzzy Analytical Hierarchical Process (FFAHP) and Simple Additive Weighting (SAW). Based on the obtained percentage ratios and the information shared, it is determined that for the given number of failed handoffs, the level of collaboration that leads to efficient results is between 20% and 50%.
