Making Field-Scale Chemical Enhanced-Oil-Recovery Simulations a Practical Reality With Dynamic Gridding
Authors: Hoteit Hussein , Chawathé Adwait 
Published: June 2016

Summary
Many improved-oil-recovery (IOR)/enhanced-oil-recovery (EOR) processes such as chemical, miscible, and steamflooding are often associated with complex flow mechanisms that manifest at the displacement front. Viscous fingering, polymer/surfactant dilution, and mixing effects are some of these mechanisms. Accurate modeling of these phenomena requires simulations on high-resolution grids to properly capture the physics in the vicinity of the displacement front. Unfortunately, high grid resolutions incur longer simulation times. Thus, past efforts at running full-field gas or chemical EOR (CEOR) simulations were frequently deemed impractical.
The advancement in computational power from software, hardware, and parallelism has indeed pushed the limits toward higher-resolution simulations. However, this may not be practical in work flows that require simulations on many models to manage uncertainties. Dynamic gridding is one approach that attempts to adjust the grid resolution as needed during the run time. No a priori knowledge is assumed regarding the fluid-flow pathways. The simulator can track the location of the displacement front, refine the neighborhood cells, and later coarsen them back as the front progresses. The advantage is reducing the number of gridblocks and, therefore, the computational time, compared with the fully refined grid, while preserving the fluid-flow physics. Although this technology is not new in reservoir simulation, there are persisting challenges in the existing methods related to the computational overhead associated with cell remapping, transmissibility recalculation, and grid upscaling and downscaling.
A new dynamic-gridding functionality has successfully been implemented into our in-house simulator. The key achievements are: (1) eliminating grid remapping and transmissibility recalculation at the run time, (2) capturing heterogeneity associated with all levels of grid refinements, (3) modeling complex geology with nonuniform gridding, and (4) tracking multiple fronts associated with surfactant–polymer (SP) and chase-water slugs. We discuss how we overcame the bottlenecks to leverage this technology from prototypes to complex cases. We also demonstrate our method on prototypes and field cases under CEOR recovery processes.
Microfluidic PVT--Saturation Pressure and Phase-Volume Measurement of Black Oils
Authors: Molla Shahnawaz , Mostowfi Farshid 
Published: June 2016

Summary
In this work, we present a small-scale pressure/volume/temperature (PVT) cell that allows for the measurement of saturation pressure and phase-volume ratio by use of only a few microliters of black-oil samples. This novel PVT measurement technique has been successfully tested on live samples at elevated pressure (86 MPa) and temperature (150°C).
In the microfluidic PVT platform, the small microfluidic device performs the same function as the laboratory-scale pressurized visual PVT cell. At the heart of the microfluidic device, is a long and narrow capillary, densely packed in a serpentine shape, embedded on the device. The capillary is nearly 1 m long and has a total volume of 5 µL. The microfluidic device is fabricated with glass and silicon, which allow visual monitoring of a fluid sample at various pressures and temperatures. To acquire PVT data, the pressure in the capillary is systematically reduced to accurately detect the appearance of micron-sized gas bubbles in a sample at saturation pressure. Because of the small thermal mass of the device, the temperature of the sample can be changed rapidly, which enables the measurement of multiple saturation pressures in quick succession. Below the saturation pressure, the growing gas bubbles form a segmented gas/liquid distribution in the capillary. The lengths of the liquid and gas segments are measured in real-time with an automated image-capturing and analysis tool to determine the gas/liquid phase-volume ratio at a given pressure.
Validation tests have proved this technique to be repeatable and feasible for rapid PVT measurements of black oils [gas/oil ratio (GOR) ranging from 102 to 143 m3/m3]. The results presented in this study demonstrate that the microfluidic PVT system can measure saturation pressure and phase-volume with data quality comparable to that of the conventional PVT method, however, with significantly smaller sample volume and faster turnaround. The microfluidic PVT system is demonstrated to have the potential to become a reliable and portable measurement platform.
A Case Study on Miscible and Immiscible Gas-Injection Pilots in a Middle East Carbonate Reservoir in an Offshore Environment
Authors: Kumar Jitendra , Agrawal Pawan , Draoui Elyes 
Published: June 2016

Summary
Hydrocarbon-gas injection is one of the most widely applied processes in the oil industry and is a promising enhanced-oil-recovery (EOR) method for use in Middle East carbonate oil fields. Gas injection improves the microscopic-displacement efficiency and generally acts as pressure maintenance; however, unfavorable mobility ratio can negatively affect the ultimate recovery because of viscous fingering and gravity override.
This paper describes two gas-injection pilots that have been implemented in offshore Middle East carbonate reservoirs: a secondary and a tertiary gas injection through line drive to assess injectivity, productivity, macroscopic-sweep efficiency, flow assurance, and operational efficiency in a field that has a long water-injection history. A strong monitoring plan, including an observer well, was applied through time-lapse saturation logging, pressure measurements, production testing, and a tracer campaign to evaluate the pilot efficiency and address key uncertainties upfront before full-field application.
This paper describes the pilot performance in the context of full-field development, local- and macroscopic-displacement efficiency, flow-assurance issues, and operational learnings. The gas-injection performance is strongly affected by reservoir heterogeneity, gravity segregation, and the existing pressure gradient, and the history match performed indicates near-miscible or miscible behavior depending upon local pressure regimes, which thus govern the ultimate recovery. The history match also shows that for the same pilot, performance can be further improved through water-alternating-gas (WAG) injection, resulting in a viable development scheme for full-field implementation.

La calidad de vida y la adherencia al tratamiento poseen una gran relevancia en aquellos pacientes que presentan enfermedades crónicas. El objetivo de este trabajo es conocer y evaluar ambos parámetros, en una población de pacientes de enfermedad de Parkinson. Para ello, se ha realizado un estudio transversal, a través de los cuestionarios de PDQ-39 y de Morisky-Green, en 95 pacientes de la citada enfermedad pertenecientes a alguna de las asociaciones de pacientes y familias de la provincia de Albacete. Los datos muestran una puntuación media de 33,47% en el PDQ-39, siendo los dominios de peor puntuación los referidos a movilidad y malestar físico. Por otro lado, un 31,6% de los pacientes se clasificaron como adherentes al tratamiento. Respecto a este parámetro, constatamos que, el factor principal relacionado con una adecuada adherencia, fue la importancia dada a su medicación por el propio paciente. No se ha encontrado ninguna asociación entre adherencia y calidad de vida.

Los tumores odontogénicos forman un grupo de lesiones de los maxilares que se originan en alguna alteración del patrón normal de la odontogénesis. Dentro de ellos se tiene al ameloblastoma que es probablemente el de mayor controversia en cuanto a su manejo, dada su conducta local agresiva, su elevada tasa de recurrencia y su pequeña probabilidad de malignización. Las radiografías cumplen un papel importante en la evaluación de este tumor; pero su principal limitación es que son estudios por imágenes en dos dimensiones. La tomografía computarizada de haz cónico (cone beam) es una valiosa herramienta que permite una exhaustiva observación de las estructuras anatómicas, gracias a la posibilidad de efectuar cortes en diferentes planos del espacio; todo esto debido a las diferentes opciones de visualización que proporciona. Por consiguiente, la evaluación del ameloblastoma es mucho más completa y permite analizar los tejidos óseos sin distorsión ni magnificación.
