Background SARS-CoV-2 infection has caused variable clinical outcomes including hospitalization and death. We analyzed state-level data from the North Carolina COVID-19 Surveillance System (NC COVID) to describe demographics of those infected with SARS-CoV-2 and to describe factors associated with infection-fatality in North Carolina. Methods This was a retrospective cohort study using surveillance data on positive SARS-CoV-2-infected individuals (N = 214,179) identified between March 1, 2020, and September 30, 2020. We present descriptive statistics and associations among demographics, medical comorbidities, and SARS-CoV-2 infection-fatality. Results Median age for residents with reported SARS-CoV-2 was 38 (IQR 23–54). Age was strongly correlated with SARS-CoV-2 infection-fatality. Greater infection-fatality was noted among those who identified as Black across all comorbidities. Coexisting chronic disease was associated with greater infection-fatality, with kidney disease demonstrating the strongest association. Limitations A high percentage of missing data for race/ethnicity and comorbidities limits the interpretation of our findings. Data were not available for socioeconomic measures that could aid in better understanding inequities associated with SARS-CoV-2 infection-fatality. Conclusions Among North Carolinians identified with SARS-CoV-2 via surveillance efforts, age, race, and comorbidities were associated with infection-fatality; these findings are similar to those of studies using different source populations in the United States. In addition to age and other nonmodifiable variables, systematic differences in social conditions and opportunity may increase the risk of SARS-CoV-2 infection-fatality among Black Americans compared to other races/ethnicities.

Less than 2% of all hematogenous osteomyelitis occurs in the pubic symphysis, making it a very uncommon condition. 10-15% of all instances of extra-pulmonary tuberculosis are caused by skeletal TB. We describe a rare instance of pubic osteomyelitis caused by tuberculosis in a 58-year-old woman who initially complained of discharge in the suprapubic region for 8 months. Patient was admitted due to suspected pubic symphysis osteomyelitis caused by TB. Based on preoperative studies, surgery was planned. Due to a suspicion of tuberculosis, debridement was performed and stimulan antibiotic beads were inserted. CB-NAAT and histopathology samples were sent. When CB-NAAT tested positive for multidrug-resistant tuberculosis (MDR-TB) and started on antitubercular therapy (ATT), HPR indicated granulomatous inflammation. After receiving MDR-TB treatment, there was no discharge from the location. Following surgery, there was a year of follow-up. Patient made a full recovery without any site discharge. This example serves to illustrate our approach to treating pubic symphysis osteomyelitis caused by TB. Osteomyelitis of the pubic symphysis, stimulating antibiotic cement beads, CB-NAAT, MDRTB, ATT.

Background: Family's socio-economic status may significantly influence parenting style. Therefore, this study aims to investigate the relationship between attachment styles of 7 to 12-year-old children, parenting styles, and the socio-economic status of parents.
Methods: This was a cross-sectional and correlational study. The study population included 7 to 12 children who studied in elementary schools of Tehran in 2021. A sample of 95 individuals were selected by random sampling method and evaluated by questionares regarding Socio-Economic status (SE) (Ghodratnama, 2013), Parenting Style (PS) (Baumrind, 1973), Kinship Center Attachment (KCA) (Halpern and Kappenberg, 2006). The information obtained from the samples was analysed by Pearson correlation coefficient through SPSS 22 software. The level of significance was considered 5%.
Results: The sample group consisted of 100 parents of 7- to 12-year-old children in Tehran city. The results showed a significant correlation between the attachment styles of the children and parenting styles and the socio-economic (r= -.284, p<0.01) status of parents. In parenting styles there was a significant relationship between authoritive parenting style and positive adjustment (p<0.05), emotional reactivity (p<0.05), negative behaviour (p<0.01) and distancing from caregiver support (p<0.01). There was also a significant relationship between authoritarian and positive adjustment (p<0.01), negative behaviour (p<0.01), distancing from caregiver support (p<0.01). A significant relationship was observed between permissive and negative behavior (p<0.05).
Conclusion: Both authoritative and permissive parenting styles seem to be dysfunctional. They cause different behavioural and emotional issues in children due to their attachment styles.

Complex Operation to Insert Coiled Tubing Through Parted Production Tubing and Regain Pressure Integrity for Plugging and Abandonment
Authors: Rondon Fajardo Sergio A , Adams Edward 
Published: March 2023

Abstract
At the end of 2020, complex well anomalies were identified in the previously shut-in, highly deviated well A in deepwater Gulf of Mexico. Closely monitored wellbore pressures indicated A/B annulus communication, and remedial slickline diagnostics discovered the tubing was parted between ~4,250 and 4,270 ft measured depth.
The abnormal well conditions and the presence of a single barrier on both the A-annulus and B-annulus triggered the well anomaly process, and action was taken to mitigate the risk profile by commencing abandonment operations prior to the start of the hurricane season.
The well anomaly risk assessment indicated the highest risk was the single barrier on the B-annulus as it had a history of failures and repairs. The outcome was to attempt to further mitigate the risk profile by commencing zonal isolation operations. To achieve a safe operation, a real-time coiled tubing (CT) downhole measurement system and dynamic interpretation software were used to mitigate the risks involved in accessing the lower section of the parted production tubing, pressure testing the completion, perforating the tubing, confirming the firing of the tubing-conveyed perforating guns, and pumping a balanced cement plug in the tubing and annulus after setting the cement retainer.
This study proposes an innovative approach to integrating CT, telemetry, and mechanical wellbore isolation tools to increase operational efficiency. Real-time bottomhole pressure, temperature, and casing collar locator (CCL) measurements proved invaluable by providing the necessary guidance to successfully set the inflatable packer and fire the perforating guns. They also provided pressure confirmation that tubing integrity issues did not allow cement in the A-annulus to escape into the production tubing on to the backside of the CT.

Abstract
Sand production remains one of the major challenges in managing mature fields in Malaysia. Wells that experience severe sand production due to primary sand control failure require remedial solutions to continue producing without jeopardizing asset integrity. In these cases, operators rely heavily on through-tubing metallic sandscreen (TTSS), however, the applications remain limited due to the short TTSS lifespan, especially in wells in a high erosive environment. With increased intervention risk, frequent replacement is both economically and operationally unfeasible. Therefore, most high gas-oil ratio (HGOR) wells remain closed-in today, in need of a durable sand screen that can withstand high erosional velocity. Various types of erosion resistant through-tubing sand screens (ER-TTSS) have been implemented to test their sustainability and longevity in highly erosive environments. Additional challenges can be associated with the actual deployment of these remedial solutions into mature wells.
This paper will discuss the performance of Malaysia's first installation of bonded bead sandscreen in HGOR well, Well #1 at offshore East Malaysia. Instead of using conventional mesh or wire wrapped type as filtration media, bonded bead sandscreen incorporates tightly bonded beads to filter sand and is expected to have superior performance over conventional metallic TTSS. Prior to installation, computational fluid dynamic (CFD) simulation and sand retention test (SRT) were conducted to determine sand erosion risk and optimize the screen design for Well #1. The information gathered from the CFD was then utilized to optimize the tubular components and minimize the effect of erosion on the complete bottom hole assembly (BHA). Additionally, well #1 was on an unmanned production platform; therefore, the deployment options for this intervention had to be considered during the early planning phase of the operation. A combination of slickline unit with suitable pressure control equipment was selected to minimize personnel on board and match deck load limitations while ensuring proper service delivery.
The outcome of pilot testing of bonded bead sandscreen in Well #1 will be discussed. Recommendations for future optimization will also be included to ensure that bonded bead sandscreen remains one of the competent through-tubing sand solutions, especially for HGOR wells. Furthermore, the operational techniques that were utilized to reduce the operational risk and costs will be discussed in order to demonstrate how such wells can be intervened in a cost-effective manner to extend the asset's life.

Abstract
One of O&G operator in Indonesia is scheduled to have a re-entry and drilling campaign at their deepwater field. The re-entry program objectives were to cut 5-1/2", 17#, 13Cr-L80 tubing and POOH existing upper completion prior P&A operation. Due to the well condition the chosen cut depth was at high inclination and multiple control lines need to be severed. A cutter with new design machining arm shaped like tiger claw was chosen to perform the cut. This operation was an outstanding achievement and the first time for deepwater in the region.
A conventional way of tubing cut is putting the tubing in tension to prevent cutting blades got pinched and increase the chance of successful cut. However, the challenge for tubing cutting at this well was not only to cut the multiple control lines but also tubing hanger was not preferred to be unlatched prior tubing cut. The mechanical cutter should be able to cut under compression and also reach control lines with total OD of 6.916". Mechanical cutter with new design tiger claw blade was chosen due to its ability to cut the tubing under compression and also the blade arms could expand increases the cutting range to 7.2" guaranteeing continuation cutting beyond tubular OD through the multiple control lines.
As this will be the first time in Indonesia, a SIT was performed in two conditions, under compression and neutral, with results confirming the cutter was able to cut tubing and multiple control lines. The cutter was deployed using e-line with tractor conveyance due to high degree inclination and positioned 1m below the tubing coupling to ensure the control lines were still in tension as it was close to the cable clamp.
The new machining arm technology produces a grinding effect to cut through the tubing and as it expanded reaching the control lines, the blades keep grinding the tubing body and scored the control lines. After 129mins effective cutting time and confirmed with the circulation from annulus to tubing, it was decided to stop and POOH the cutter. When the cutter at the surface, it was measured that the blade had expanded, and operation continued to unlatch tubing hanger and POOH upper completion. The tubing was cut with a clean and smooth surface with control lines sheared at cutting depth.
With the newly designed cutting elements, enabling a safe and efficient cutting operation. This solution eliminates the risks of unlatching the TH and put tubing in tension, the cost of rig time and ensuring no interruption to the well program. Operational details, including job planning and lessons learned will be discussed in the paper
A Cost-Effective Approach to Enhance Coiled Tubing Accessibility in Extended Reach Wells with the Use of a Special Lubricant: A Case History
Authors: Chishti Sadaf Shoukatali , Sima Li , Bukhari Mohamed Abd-Elrahman 
Published: March 2023

Abstract
As more and more longer extended reach (ER) wells are being drilled in the middle east, coiled tubing (CT) interventions are becoming a predominant challenge in terms of reaching total depth (TD). A major requirement for the operators is that CT reaches TD cost effectively to perform stimulation or any mechanical intervention. This paper discusses case histories for two extended reach wells where a 2-inch CT achieved 100% accessibility with the use of special CT lubricant.
There are many methods to enhance CT reach, but the simplest and most cost-effective method is the use of metal friction reducing lubricants. The methodology of using the lubricant is either based on filling the entire well with the lubricant solution during run-in hole or selective placement in specific intervals. Selective placement of lubricant is further cost efficient but can be compromising if the target depth is not reached during the actual job. However, by performing pre-job tubing force analysis and modelling various scenarios, it is possible to optimize the volume of lubricants required with minimized risk on the outcome.
In the first case history, full use of lubricant was applied from the beginning of CT run to successfully access TD in one of the longest well of the field with a TD in excess of 24,000 ft. and lateral length 14,000 ft. Pre-job modelling performed with offset data in similar completions predicted an early friction lock. After the first run, lubricant solution placement was optimized by conducting a thorough tubing force analysis (TFA) that helped understand friction profiles and helical pitch development determining the optimum intervals for pumping lubricants. Post job force match showed that the lubricant reduced the effective coefficient of friction (COF) by more than 30%. In the second case history, CT was able to reach TD of around 27,100 ft after lubricant placement was optimized and it reduced the COF by up to 50% from assumed base case.
The case histories presented in this paper demonstrate the benefits of using the special CT lubricant in reducing CoF and enhancing accessibility for CT in ER wells. It also discusses a methodology to optimize lubricant placement in ER wells with help of pre-job modelling on a proprietary CT simulator.

AbstractFollowing the rig-based well testing stage, completion programs of high-pressure wells in North Kuwait call for well killing with heavy oil-based mud (OBM). The workover rig is then demobilized, and production flowlines are installed. Well activation plans are carried out riglessly, and coiled tubing (CT) is instrumental to bringing the wells back to sustainable production. One of the major drawbacks from this practice is the formation damage generated by the OBM, which often requires additional interventions for remediation.To address this limitation, a new approach leveraging instrumented CT for temporary well suspension was recently implemented. Real-time downhole telemetry is enabled by an optical line installed in the CT pipe and used to accurately set a through-tubing inflatable packer (TTIP). Once the latter is anchored at the planned depth, above the interval open to the formation, CT is disconnected from the packer assembly, and the fishing neck is protected with a sand plug. CT is then retrieved to surface, and a slickline dump bailer is run to spot cement on top of the sand plug. Once the cement has set, CT is run to displace the wellbore to kill fluid.Two pilot wells were selected to implement this new approach for temporary well suspension. Both wells had a maximum potential wellhead pressure in the order of 7,400 psi, and 15.0-ppg OBM was originally planned for well suspension purposes. Upon completion of the zonal testing program - which included initial stimulation, well activation, and flowback - instrumented CT was run with high- pressure rotary jetting to condition the TTIP setting depth and displace the wellbore with brine, after which, a shut-in wellhead pressure near 2,000 psi was observed. In the next CT run, TTIP was set close to the end of the production tubing, and critical stages, such as depth correlation, packer inflation, and packer anchoring testing were closely controlled via real-time downhole measurements. Additional verification of the TTIP effective seal was carried out before the CT was disconnected from the packer assembly through an inflow test relying on live downhole pressure monitoring. Once the TTIP released, the temporary suspension was completed following the methodology described above. Finally, the wells were observed at surface with zero pressure for more than 24 hours, receiving acceptance from the operator.This alternative approach for temporary well suspension represents an innovative solution to bring wells back into production without additional restimulation or well activation. This methodology greatly relies on CT real-time downhole telemetry, and operators from the Middle East can benefit from the experience gained in this project.

Abstract
A workover campaign in low bottomhole pressure gas wells in China South Sea was planned, where a through tubing retrievable inflatable bridge plug (TTIRBP) was chosen to provide zonal isolation.
Challenging circumstances include zero fluid contamination allowed, small through tubing restriction as opposed to large setting ID, shallow working depth and tight working schedule to complete the workover activity during the typhoon season. To mitigate the fluid contamination challenge, Nitrogen-driven setting of TTIRBP was selected.
Through Tubing Intervention (TTI) services were safely and successfully completed by nitrogen-driven in all six wells via coiled tubing deployment and met the customer workover schedule deadline. After that, these gas wells were recovered to the same initial production rate quickly and efficiently.
This paper will provide operational details for the 6 wells in this campaign. These methods are described in detail to share the valuable experience for readers’ similar application.
