Abstract
Objectives
Socio-economic status (SES) is a well-established predictor of health outcomes; however, there is a dearth of evidence on the relationship between SES and off-road vehicle (ORV) injuries. In Ontario, all-terrain vehicles (ATVs) and snowmobiles present a serious risk for preventable injury. This study assessed the association between area-level material deprivation and the risk of ATV- and snowmobile-related injuries in Ontario, as well as the impact of sex and age.

Methods
A population-based, repeat cross-sectional study was conducted using administrative data of ATV- and snowmobile-related emergency room visits from 2003 to 2018. Material deprivation was measured using the Ontario Marginalization Index, which assigned a score and quintile of deprivation to each dissemination area in Ontario. Age-standardized incidence rates and relative index of inequality values were calculated, stratified by quintile of deprivation, sex, age group, vehicle type, and health region.

Results
We found a significant, positive relationship between ORV-related injuries and quintile of material deprivation (RII = 1.28, 95% CI: 1.01–1.63). Rates of ATV- and snowmobile-related injuries remained stable over time. Across all age groups, sex, and rural categories, we found an inverse u-shaped relationship between rates of injuries and quintile material deprivation. Males, individuals living in rural areas, and adolescents and young adults experienced the highest rates of injuries.

Conclusion
Despite the positive relationship between ORV-related injuries and quintiles of deprivation, the inverse u-shaped relationship suggests that this increased risk of injury is likely related to exposure to ORVs. These results contribute to an understanding of the prevalence of the injury problem at a local level in Ontario. Stable rates of injury over time suggest that current public health programs are not sufficient in reducing these injuries, and further research should determine which factors amenable to intervention are contributing to increased risk of injury.

Published: October 2020

Aim: to assess the efficacy and safety of non-ablative radiofrequency treatment in the postpartum period in patients with vaginal relaxation syndrome and other initial manifestations of pelvic floor dysfunction (PFD).Materials and Methods. 44 patients with complaints of the initial manifestations of PFD were enrolled into prospective randomized comparative study: 30 women in the main group and 14 in the control group. Diagnostic methods included medical history collection, objective examination, assessing condition of the perineum by visual inspection; standard clinical and laboratory studies; using the questionnaire for calculating the Female Sexual Function Index (FSFI-19). Staging of pelvic organ prolapse was performed according to the POP-Q classification (Pelvic Organ Prolapse Quantification system). Measurement of the pelvic floor muscle contraction strength was performed by using a perineometer. A course of 3 procedures of radiofrequency non-ablative exposure of the vulvovaginal tissues in patients from the main group was performed 2 months after delivery, with 7-day interval. Assessment of the collagenogenesis and neoangiogenesis was carried out base on measuring expression level of the mRNA specific to proteins of the vaginal connective tissue by using real-time polymerase chain reaction.Results. Our study allowed to find that anatomical and functional state of the vulvovaginal area and perineum were significantly improved as well as relief of PFD symptoms. The level of expression of decorin mRNA in patients from the main group before and after treatment were 0.1 ± 0.035 and 0.047 ± 0.002, respectively (p = 0.02, Wilcoxon t-test). The median values of mRNA expression of matrix metalloproteinase type 2 before and after treatment were 0.0177 and 0.013, respectively (p = 0.03). The expression of type III collagen mRNA before and after treatment was 0.0675 and 0.0109, respectively (p = 0.03).Conclusion. The data obtained by us demonstrate positive effects after using monopolar radiofrequency therapy on the tissues in the vulva, vagina and perineum of patients in the postpartum period. However, clinical improvement in patients with PFD represents a cumulative result of morphological and functional changes in the tissues of the perineum as well as vulvovaginal region. We believe it is irrational to associate such positive effects solely with altered magnitude of the metabolism of collagen and other extracellular matrix proteins, due to dynamic balance and genetic determinism of decay and production of connective tissue proteins. The safety and role of radiofrequency therapeutic procedures in prevention and treatment of PFD require further investigation by assessing new markers and research methods, by extending observation period as well as increasing amount and quality of clinical observations.

Published: October 2020

Aim: to assess changes in parameters of vascular stiffness, central aortic pressure (CAP) as well as reflected pulse wave in women in different phases of the climacteric period.Materials and Methods. An open non-randomized single-center comparative study was conducted with 384 menopausal women subdivided into: Group 1 – 168 women at menopausal transition, Group 2 – 216 women at early postmenopause. A 24-hour blood pressure (BP) monitoring was performed with assessing daily dynamics of parameters of arterial stiffness, CAP and reflected pulse wave. The aortic pulse wave velocity and local aortic stiffness were estimated.Results. It was found that women in early postmenopausal period vs. menopausal transition showed significantly higher values of daily central BP combined with more prominent changes in vascular stiffness. Menopausal women were characterized by lowered difference between nocturnal central and peripheral BP level (less amplified nocturnal vs. diurnal peripheral BP magnitude), which is associated with a greater augmented CAP at this time point. Such pattern was more pronounced in women at postmenopausal period.Conclusion. Women in climacteric period were found to have increased vascular stiffness combined with elevated CAP, decreased amplification of pulse pressure and increased amplitude of the reflected pulse wave may be associated with increased risk of cardiovascular complications. Much more prominent changes were noted in women in early postmenopausal period.

Introduction.Preeclampsia (PE) is a specific complication of pregnancy holding a lead place in maternal and perinatal morbidity and mortality worldwide. The development of PE in the maternal body is accompanied by severe hypercoagulation, disturbed anticoagulation and fibrinolytic systems. As a result, vascular microthrombosis in diverse organs with developing endothelial dysfunction, impaired utero-placental blood circulation emerge that leads to adverse perinatal outcomes.Aim:to study status of coagulation arm in pregnant women with moderate and severe PE, after delivery by cesarean section, to optimize management of the postoperative period.Materials and Methods.There were enrolled 50 pregnant women with PE: 16 with moderate and 34 with severe PE after surgical delivery. A status of coagulation arm was examined by evaluating major parameters in coagulogram (fibrinogen, activated partial thromboplastin time, prothrombin, international normalized ratio) as well as assay for early diagnostics of blood clotting disorders to reveal bleeding and thrombosis risks.Results.It was found that prior to surgery patients with severe PE had significantly increased clot growth rate (V) by 1.09-fold (p = 0.001), relative clot density (D) by 1.15-fold (p = 0.001), and time of spontaneous clot appearance (Tsp) was accelerated by 2-fold (p = 0.001) compared to moderate PE. After surgical delivery, patients from both groups had changes evidencing about activated coagulation system: increased V, D, as well as the Tsp. Upon that, all such parameters in patients with severe PE were significantly elevated: the V – by 1.25-fold (p = 0.005); the D – by 1.1-fold (p = 0.02); the Tsp was accelerated by 2-fold (p = 0.03) compared to patients with moderate PE. All parameters in both groups tended to normalize on day 5 after surgical delivery, but patients with severe PE were shown to have significantly increased the V – by 1.5-fold (p = 0.001); the D – by 1.14-fold (p = 0.001); the clot size – by 1.14-fold (p = 0.001); the Tsp – accelerated by 41 % (p = 0.001) compared to patients with moderate PE.Conclusion.Thus, patients with moderate and severe PE after surgical delivery by cesarean section were featured with markedly activated coagulation hemostasis, which may justify a prolonged use of low-molecular-weight heparins in the postoperative period, especially in patients with PE.

Abstract
Waterflood conformance is a significant problem in the West Sak field of Alaska. Re-assembling Pre-Formed Particle Gels (RPPG) have been used to treat Void Space Conduits (VSC) and repair the "short-circuited" waterflood. These VSC’s are typically formed by sand producing wormholes. Several dozen VSC solutions have been implemented since 2006, including molten wax, cement blends, and pre-formed particle gels. To date, all the solutions have been faced with various limitations due to the low reservoir temperature and poor sand consolidation.
A good percentage of the pre-formed particle gel (PPG) solutions have been successful in sealing off VSCs, but often show limited longevity that can range from as little as several weeks to several years. An effort was undertaken to develop a product that would provide enhanced stability in the VSC and extend solution life beyond the current range. A cost-effective conformance solution was developed with increased mechanical strength through a re-crosslinking process known as RPPG. The goal of the RPPG solution is to provide a longer-term repair to a VSC and restore the primary water flood characteristics.
This paper will present the results of the seventeen RPPG solutions that have been pumped between 2017 and 2019 in the West Sak field on the North Slope of Alaska. RPPG treatments have shown a 23% improvement over traditional PPG treatments at the economic payout during the field trial. There have been some significant learnings through this time period. The focus of this paper will be to review the VSC problem understanding and the reason for the RPPG product development, detail the evolution of RPPG job design over time and provide results and operational knowledge from the field trial efforts.
The latest advancements in conformance engineering will be of interest to Reservoir and Production Engineers who are focused on supporting and optimizing conventional waterflooded assets, particularly when faced with conformance issues in an unconsolidated reservoir. In addition, the field results will be useful to those seeking to implement RPPG solutions in their area of operation.
A New Machine Learning Procedure to Generate Highly Accurate Synthetic Shear Sonic Logs in Unconventional Reservoirs
Authors: Chaikine Ilia Alexandrovich , Gates Ian Donald 
Published: October 2020

Abstract
Shear sonic travel time (DTS), along with compressional sonic travel time and bulk density are required in order to estimate rock mechanical properties which play an important role in fracture propagation and the success of hydraulic fracture treatments in horizontal wells. DTS logs are often missing from the log suite due to their costs and time to process. The following study presents a machine learning procedure capable of generating highly accurate synthetic DTS curves. A hybrid convolutional-recurrent neural network (c-RNN) was chosen in the development of this procedure as it can learn sequential data which a traditional neural network (ANN) cannot. The accuracy of the c-RNN was superior when compared to that of the ANN, simple baselines and empirical correlations. This procedure is a cost effective and fast alternative to running DTS logs and with further development, has the potential to be used for predicting production performance from unconventional reservoirs.

Abstract
Affinity law teaches that when the rotating speed of the electric submersible pump (ESP) pump is tripled, the flow rate triples and the head increases to nine times the original pump. Thus, a high-speed ESP has the potential of delivering increased production at deeper setting depths and opportunity for shorter equipment allowing operators to land the equipment in shorter tangent sections. Operation at high-speed also presents additional challenges with one of the most significant being increased potential for abrasive and erosive wear. This study compares pump performance from slurry testing to help evaluate the potential trade-offs system performance versus wear when operating at higher speeds.
When deploying ESPs in sandy applications, sand particles can enter the seal clearance between impeller and diffuser creating 3-body abrasion wear. Meanwhile, the 2-body erosion wear in stage flow path reshapes the hydraulic geometry and causes additional losses. Both abrasion and erosion cause pump head reduction, efficiency deterioration, and thrust increase. Data was collected during slurry testing for comparison of performance over the test period. The in situ head change and thrust change were monitored during the slurry test. Pre and posttest stage dimensional data were gathered for comparison. Sand samples were gathered and analyzed to ensure similar slurry conditions applied to all the tested pumps.
Slurry testing and analysis for the evaluation of ESP pump stage performance deterioration for a stage operated at 10,000 RPM as compared to a stage operated at 3,500 RPM will be provided. The pump performance degradation and dimensional wear were compared. This demonstrates higher speed ESP pump components can be created that show similar abrasive wear performance to current ESP pump.
A 10,000 rpm ESP pump completed slurry testing while measuring pressure, temperature, flow and thrust. The results provide pump performance deterioration trend in a sand application and helps to understand physics of stage wear mechanism. This is the first of this type of testing apparatus to authors’ knowledge. It also serves as a backbone in high-speed pump validation program.
A Quick and Rigorous Approach for Estimating Reservoir Permeability from DFITs
Authors: Cai Yuzhe , Dahi Taleghani Arash , Hawkes Robert 
Published: October 2020

Abstract
Diagnostic fracture injection tests (DFITs) have been widely studied and implemented in unconventional reservoirs to derive properties such as closure stress, pore pressure, and permeability. During a DFIT, a small volume of water is pumped into a formation to create a small-sized crack. Formation permeability is typically obtained by means of modeling fluid leakoff during the shut-in period. Early studies have assumed a constant fluid pressure boundary condition on the fracture walls or a constant leakoff rate into the formation. However, the results deduced based on these assumptions may introduce significant errors because the fluid pressure inside a fracture dissipates quickly as the fluid leaks off into the formation. In this study, we propose a material balance approach to obtain formation permeability using DFIT data. The proposed analysis takes into account fluid leakoff during both fracture propagation and well shut-in periods. To model fluid leakoff during fracture propagation, we adopt the superposition principle to decompose the problem into two separate problems; we then obtain the analytical solution. Two synthetic cases are presented to validate the proposed analysis. The results suggest that the proposed approach provides a good estimation of formation permeability. This approach has broad field application potential, as it can be used even when pressure data contains significant levels of noise. In addition, the solution is more accurate than those provided in available studies of formation permeability estimation using DFITs data, especially when formation permeability is not extremely tight.
Stranger Things: Pairing Cementing Fluid Technologies to Overcome Challenging Isolation Requirements
Authors: Shine Joseph , Qasmi Urooj 
Published: October 2020

Abstract
Exploration wells tend to produce challenging cement placement conditions with varying design elements to achieve the isolation requirements such as avoiding lost circulation and exhibiting high mud removal efficiencies. To satisfy both of these design elements, development of a cementing fluid (spacer) has paired multiple technologies helping overcome these requirements. The cementing fluid combines a lost circulation spacer, shown to be a cement placement aid, and a scrubbing or scouring additive, demonstrating support for high mud removal efficiencies. Thorough function-based assurance testing helped mitigate the identified deployment risks, due to their plugging natures, in combining these technologies.
The paper will document applications where the cementing fluid helped achieve the isolation requirements when faced with wellbore instability during placement as well as the associated mud removal challenges from these limitations. The use of the cementing fluid may help others achieve success when faced with similar challenges.
