Near-Wellbore and Reservoir Effects in In-Situ Combustion
Authors: Chavez Mario-Luis Rodriguez , Glatz Guenther , Clemens Torsten , Kovscek Anthony 
Published: September 2016

Summary
To operate fields under in-situ combustion (ISC), the near-wellbore dynamics and far-field conditions have to be considered. In the near-wellbore region of vertical injection wells, the flow advancement of the combustion front is characterized by high velocities. Farther away from the injection wells, the advancement rate of the combustion front is much smaller. For a line-drive configuration, the advancement of the front slows down from several meters per day near the wellbore to several centimeters per day in the far-field region.
To investigate the effects in the near-wellbore region and far-field conditions, laboratory experiments and simulations were performed and compared with the behavior of a Central European field produced by using ISC.
The laboratory experiments covered the kinetics in the near-wellbore region as well as the far-field region by applying various heating rates and by preheating a kinetic cell before injecting air. The dynamic effects were investigated with a combustion tube. Mechanistic numerical simulation was based on the kinetics derived from the kinetic-cell experiments and applied to the combustion tube. The same set of conditions was then used to simulate the near-wellbore conditions in the Central European field and far-field conditions.
The results show that, in the near-wellbore region, the advancement of the combustion front is fast compared with heat conduction ahead of the front. Hence, low-temperature-oxidation (LTO) reactions and high-temperature-oxidation (HTO) reactions, as derived from the kinetic-cell experiments, are occurring in different distances from the injection well. In the far field, heat conduction ahead of the front and the flow of hot combustion gases preheat the reservoir before oxygen arriving at the combustion front. For these conditions, LTO and HTO reactions are occurring at the same location.
In the Central European field produced with ISC, the various operating conditions are shown at an example well. Four different phases of production can be seen: (1) oil production with cyclic steam stimulation (CSS), (2) shut-in of the well to stabilize the combustion front that is approaching, (3) oil-production response of the combustion front, and (4) conversion of the well for air injection. The air-injection rate is slowly increased to avoid too-high temperatures in the early-injection phase (faster advancement of the heat front than heat conduction). The distance of the wells is approximately 70 m to allow sufficient oil recovery per well and speed of the combustion front.
Transient Response in Arbitrary-Shaped Composite Reservoirs
Authors: Idorenyin Etim H. , Shirif Ezeddin E. 
Published: September 2016

Summary
Use of regular-shaped analytical models to history match geometrically complex reservoirs may provide misleading results, especially in situations where the transients are in the transition regime. In this regime, the transients are somewhere between infinite-acting and fully boundary-dominated flows. This means that some, but not all, of the reservoir boundaries influence flow dynamics. As a result, analytical models are unable to accurately capture the effects of the geometrically complex reservoir boundaries; the more irregular the reservoir or drainage area geometry is, the greater its influence on well performance, and, therefore, the greater the deviation of analytical models from field behavior. The boundary element method (BEM) has been used to model arbitrary-shaped reservoirs; its input data requirement is similar to that of analytical models. In this paper, we present the Laplace-transform BEM formulation within a framework that lends itself to developing the solution for arbitrary-shaped and/or composite reservoirs of increased complexity than is currently available in literature, thus eliminating the need for first-principle derivations. The focus here is on two-dimensional flow of a slightly compressible fluid. Our formulation is not only useful for investigating the influence of complex reservoir geometries on well performance, but also for history matching and forecasting multiwell performance, for studying the effect of large-scale reservoir heterogeneities, and for simulating mixed reservoir boundary conditions (including no-flow and constant-pressure boundaries). It permits modeling different well completion types, including hydraulically fractured vertical wells and multiply-fractured horizontal wells. In addition to modeling the response of rate-controlled wells, we also provide solution for pressure-controlled wells.
A Practical Methodology For Integration of 4D Seismic in Steam-Assisted-Gravity-Drainage Reservoir Characterization
Authors: Hadavand Mostafa , Deutsch Clayton V. 
Published: September 2016

Summary
4D seismic is a dynamic source of data that provides information about changes in reservoir-rock and -fluid properties over time. Seismic attributes are sensitive to variations in the fluid content, temperature, and pressure distribution; therefore, 4D-seismic images contain information on the nature of fluid flow within the reservoir. Perhaps the most-reliable and -important information that can be learned from 4D-seismic images is related to anomalies in fluid flow within the reservoir. During steam-assisted gravity drainage (SAGD), the steam-chamber propagation is fairly clear from 4D-seismic images, mainly because of higher gas saturation in the chamber. Therefore, anomalies are revealed by the absence or unexpected location of the steam chamber. In this paper, a practical methodology is proposed for consideration of anomalies identified from 4D-seismic images in geostatistical reservoir models. The geostatistical realizations are updated to enforce missing anomalies and improve reservoir characterization. The updated models are suitable for reservoir decision making and management.

Published: September 2016

Background:
Severe hip osteoarthritis is known to lead to secondary osteoarthritis of the knee joint. It is not clear whether contracture or a leg length discrepancy is more important in determining the knee alignment.

Methods:
In this study, 48 hips in 48 patients with a unilateral completely dislocated hip (Crowe IV) were recruited. The patients were divided into two groups (Crowe IVa and IVb). The Crowe IVa group had completely dislocation with psudo-articulation, and the Crowe IVb group had completely dislocation without psudo-articulation. The lower limb alignment was divided into three patterns according to the femorotibial angle; varus (≥176 degrees), neutral(170 to 175 degrees) and valgus(≤169 degrees).

Results:
The combination of valgus alignment on the affected side and varus alignment on the unaffected side, so-called “windswept deformity” was observed in 12.5% of the patients; this included 18.2% and 7.7%, in the Crowe IVa and Crowe IVb groups, respectively. The valgus alignment on the unaffected side, namely “long leg arthropathy,” was found to have occurred in 6.3% of the patients, including 13.6% of the patients in the Crowe IVa group; there were no cases of long “leg arthropathy” in the Crowe IVb group.

Conclusion:
The lower limb alignment on the unaffected side had a tendency to be varus in the Crowe IV patients. The “windswept deformity” was observed in each of the groups; however, “long leg arthropathy” was only found in the Crowe IVa group.

Published: September 2016

Objective:To estimate the extent to which psychophysical quantitative sensory test (QST) and patient factors (gender, age and comorbidity) predict pain, function and health status in people with shoulder disorders. To determine if there are gender differences for QST measures in current perception threshold (CPT), vibration threshold (VT) and pressure pain (PP) threshold and tolerance.Design:A cross-sectional study design.Setting:MacHAND Clinical Research Lab at McMaster University.Subjects:34 surgical and 10 nonsurgical participants with shoulder pain were recruited.Method:Participants completed the following patient reported outcomes: pain (Numeric Pain Rating, Pain Catastrophizing Scale, Shoulder Pain and Disability Index) and health status (Short Form-12). Participants completed QST at 4 standardized locations and then an upper extremity performance-based endurance test (FIT-HaNSA). Pearson r’s were computed to determine the relationships between QST variables and patient factors with either pain, function or health status. Eight regression models were built to analysis QST’s and patient factors separately as predictors of either pain, function or health status. An independent sample t-test was done to evaluate the gender effect on QST.Results:Greater PP threshold and PP tolerance was significantly correlated with higher shoulder functional performance on the FIT-HANSA (r =0.31-0.44) and lower self-reported shoulder disability (r = -0.32 to -0.36). Higher comorbidity was consistently correlated (r =0.31-0.46) with more pain, and less function and health status. Older age was correlated to more pain intensity and less function (r =0.31-0.57). In multivariate models, patient factors contributed significantly to pain, function or health status models (r2=0.19-0.36); whereas QST did not. QST was significantly different between males and females [in PP threshold (3.9vs. 6.2, p < .001) and PP tolerance (7.6vs. 2.6, p < .001) and CPT (1.6vs. 2.3, p =.02)].Conclusion:Psychophysical dimensions and patient factors (gender, age and comorbidity) affect self-reported and performance-based outcome measures in people with shoulder disorders.

Authors: Argumedos Cesar , Pérez Diego , Romero Acosta Kelly 
Published: September 2016

La alta prevalencia de trastornos mentales en Colombia, sumada a la situación de violencia por la que atraviesa el país, son factores de riesgo incidentes para el desarrollo de algunas psicopatologías, como la ansiedad y la depresión. Este estudio tiene como objetivo conocer el estado de los trabajos de investigación realizados en Colombia desde el año 2000 hasta 2014, teniendo en cuenta las variables “trastornos emocionales” (ansiedad/depresión) e “infancia”. Para tal fin, se realizó una búsqueda bibliográfica exhaustiva en diferentes bases de datos y en revistas científicas indexadas a nivel nacional. Los resultados revelan una tendencia en el estudio de la depresión infantil en comparación con la ansiedad, sobre todo desde los años 2006 hasta 2009. La mayor parte de investigaciones encontradas utilizaron instrumentos de auto-informe para evaluar la sintomatología. En el presente trabajo se reflexionará acerca de los hallazgos encontrados y además se platearán futuras directrices de investigación sobre los trastornos emocionales en la infancia colombiana.
