Authors: Attigeri Savitha
Published: March 2018

Handwritten character recognition has been one of the active and challenging research areas in the field of image processing and pattern recognition. It has numerous applications which include, reading aid for blind, bank cheques and conversion of any hand written document into structural text form. In this paper an attempt is made to recognize handwritten characters for English alphabets without feature extraction using multilayer Feed Forward neural network. Each character data set contains 26 alphabets. Fifty different character data sets are used for training the neural network. The trained network is used for classification and recognition. In the proposed system, each character is resized into 30x20 pixels, which is directly subjected to training. That is, each resized character has 600 pixels and these pixels are taken as features for training the neural network. The results show that the proposed system yields good recognition rates which are comparable to that of feature extraction based schemes for handwritten character recognition

Published: March 2018

Objetivo. Analizar la situación actual de la atención de la salud mental a partir de un análisis socioecológico, sustentado en las percepciones del personal y usuarios de centros de salud (CS) de la Ciudad de México (CDMX). Material y métodos. Estudio exploratorio descriptivo de métodos mixtos (CUALI → CUAN). En la fase cualitativa, se entrevistó al personal de 19 centros ubicados en tres delegaciones de la CDMX y, en la fase cuantitativa, se aplicó un cuestionario a pacientes. Resultados. Se identificó la influencia e interde­pendencia de diferentes factores que impactan la atención de la salud mental (SM). El personal de salud y pacientes recono­cen escases de recursos que impactan la calidad del servicio, políticas públicas en SM que no siempre se concretan en la práctica y un modelo de atención que no permite ahondar en problemas emocionales. Conclusiones. Mejorar la atención de la SM en el primer nivel requiere de un trabajo reflexivo desde diversas ópticas.

Rock Typing in Eagle Ford, Barnett, and Woodford Formations
Authors: Gupta Ishank , Rai Chandra , Sondergeld Carl , Devegowda Deepak
Published: March 2018

Shales are the most commonly found sedimentary rocks on Earth. Most US shale plays are massive, with different maturity regions and varying prospects. There has been a paradigm shift in the understanding of shale anisotropy and microstructures in the last decade, with a high focus on the identification of sweet spots and optimal reservoir-quality zones. Rock typing is one of the sought-after techniques to achieve this objective, and it has become an integrated part of the unconventional-characterization work flow.

In this work, rock typing was performed with an integrated work flow using laboratory petrophysical measurements. The rock types were derived with machine-learning clustering algorithms—namely, K-means and self-organizing maps (SOM). The integrated work flow was applied in three different shale plays: Eagle Ford, Barnett, and Woodford.

Three different rock types were identified. In general, Rock Type 1 had the highest porosity and total organic carbon (TOC), indicative of highest storage and source-rock potential, respectively. Rock Type 1 was also the key rock type controlling the production. Rock Type 2 had intermediate porosity and TOC, whereas Rock Type 3 had the lowest porosity and TOC.

Next, core-derived rock types had to be scaled up to logs. Support vector machines (SVM), a classification algorithm, was used for scaling up. It was trained with a data set consisting of depths at which both core and log data were available. Different logs such as gamma ray, resistivity, neutron, and density were used for scaling up. Finally, a rock-type ratio (RTR) was defined from rock-type logs based on fraction of Rock Type 1 over gross thickness. The ratio thus developed was found to have a strong correlation with normalized oil-equivalent production rate.

In total, 22 wells with core data were considered for rock typing in the three shale plays. The rock types were scaled up to 95 wells at a cumulative over a 20,000-ft depth interval. The work flow shown in this paper can easily be extended to other data sets in other plays. The manual approach, on the other hand, can be prohibitively time-consuming.
Extension of Dykstra-Parsons Model of Stratified-Reservoir Waterflood To Include Advanced Well Completions
Authors: Muradov K.. , Prakasa B.. , Davies D..
Published: March 2018

Large volumes of oil are being produced by waterflooding heterogeneous reservoirs. Careful flood-pattern design, well placement, and control are required to maximize oil recovery by delaying water breakthrough and optimizing sweep efficiency. Models that analyze the waterflood's performance and predict the production forecast, such as the Dykstra-Parsons (DP) method, are routinely used for this purpose.

The DP method estimates the vertical-flooding efficiency between conventional wells producing from noncommunicating layers. This method and its various modifications have had a significant impact on the development of the theoretical description of the waterflooding process. The DP method is still routinely used for waterflood-performance prediction and analysis, flood-pattern selection, and recovery-factor calculation.

Advanced well completions (AWCs) control the fluid flow at the reservoir sandface. They have become a proven, widely used technology (particularly in waterflooded reservoirs) for modifying a production or injection well's inflow/outflow rate profile along the well. In addition to this, new AWC designs that react to water breakthrough have recently become available. Incorporating a description of the AWC performance into the waterflood-analysis models will allow fast forecasting of the production profile and oil recovery, as well as help in optimizing the AWC configuration and control at the well-design stage.

This work extends the DP method for rapid prediction of the waterflood's performance to AWC wells. It provides a simple means of estimating the additional, long-term value derived by controlling zonal flow rate using AWCs or any other means (e.g., well workover). The accuracy of the extended DP method's prediction has been verified by comparison against the results from a numerical reservoir simulator. Several examples illustrate the extended DP model's performance and value. The method's limitations and possible future extensions are also discussed.

The presented model is a simple, transparent approach to evaluating the impact on the waterflood's oil recovery efficiency (RE) of various well-completion and control options. It can be implemented as an analytical model or as a fast simulator. This model is also the missing link between the various AWC design methods available today and the AWCs' long-term value evaluation.
