Integration of Dynamic Microseismic Data With a True 3D Modeling of Hydraulic-Fracture Propagation in the Vaca Muerta Shale
Authors: Haddad Mahdi , Du Jing , Vidal-Gilbert Sandrine 
Published: August 2017

SummaryMicroseismic mapping during the hydraulic-fracturing processes in the Vaca Muerta (VM) Shale in Argentina shows a group of microseismic events occurring at shallower depth and at later injection time, and they clearly deviate from the growing planar hydraulic fracture. This spatial and temporal behavior of these shallow microseismic events incurs some questions regarding the nature of these events and their connectivity to the hydraulic fracture. To answer these questions, in this article, we investigate these phenomena by use of a true 3D fracture-propagation-modeling tool along with statistical analysis on the properties of microseismic events.First, we propose a novel technique in Abaqus incorporating fracture intersections in true 3D hydraulic-fracture-propagation simulations by use of a pore-pressure cohesive zone model (CZM), which is validated by comparing our numerical results with the Khristianovic-Geertsma-de Klerk (KGD) solution (Khristianovic and Zheltov 1955; Geertsma and de Klerk 1969). The simulations fully couple slot flow in the fracture with poroelasticity in the matrix and continuum-based leakoff on the fracture walls, and honor the fracture-tip effects in quasibrittle shales. By use of this model, we quantify vertical-natural-fracture activation and fluid infiltration depending on reservoir depth, fracturing-fluid viscosity, mechanical properties of the natural-fracture cohesive layer, natural-fracture conductivity, and horizontal stress contrast. The modeling results demonstrate this natural-fracture activation in coincidence with the hydraulic-fracture-growth complexities at the intersection, such as height throttling, sharp aperture reduction after the intersection, and multibranching at various heights and directions.Finally, we investigate the hydraulic-fracture intersection with a natural fracture in the multilayer VM Shale. We infer the natural-fracture location and orientation from the microseismic-events map and formation microimager log in a nearby vertical well, respectively. We integrate the other field information such as mechanical, geological, and operational data to provide a realistic hydraulic-fracturing simulation in the presence of a natural fracture. Our 3D fracturing simulations equipped with the new fracture-intersection model rigorously simulate the growth of a realistic hydraulic-connection path toward the natural fracture at shallower depths, which was in agreement with our microseismic observations.
Experimental Investigation of the Effect of Polymers on Residual Oil Saturation
Authors: Koh Heesong , Lee Vincent B. , Pope Gary A. 
Published: August 2017

Summary
Polymer flooding is a widely used commercial process with a low cost per barrel of produced oil, and hydrolyzed polyacrylamide (HPAM) polymers are the most widely used type of polymer. The objective of this research was to better understand and predict the behavior of HPAM polymers and their effect on residual oil saturation (ROS), to improve the capability of optimizing field design and performance. The corefloods were performed under typical field conditions of low pressure gradients and low capillary numbers. The polymer floods of the viscous oils recovered much more oil than the waterfloods, with up to 24% lower oil saturation after the polymer flood than after the waterflood. The experimental data are in good agreement with the fractional-flow analysis by use of the assumptions that the true ROSs and endpoint relative permeabilities are the same for both water and polymer. This suggests that, for more-viscous oils, the oil saturation at the end of a waterflood (i.e., at greater than 99% water cut) is better described as “remaining” oil saturation rather than the true “residual” oil saturation. This was true for all the corefloods, regardless of the core permeability and without the need for assuming a permeability-reduction factor in the fractional-flow analysis.
Equation of State for Relative Permeability, Including Hysteresis and Wettability Alteration
Authors: Khorsandi Saeid , Li Liwei , Johns Russell T. 
Published: August 2017

SummaryCommercial compositional simulators commonly apply correlations or empirical relations that are based on fitting experimental data to calculate phase relative permeabilities. These relations cannot adequately capture the effects of hysteresis, fluid compositional variations, and rock-wettability alteration. Furthermore, these relations require phases to be labeled, which is not accurate for complex miscible or near-miscible displacements with multiple hydrocarbon phases. Therefore, these relations can be discontinuous for compositional processes, causing inaccuracies and numerical problems in simulation.This paper develops for the first time an equation-of-state (EOS) to model robustly and continuously the relative permeability as a function of phase saturations and distributions, fluid compositions, rock-surface properties, and rock structure. Phases are not labeled; instead, the phases in each gridblock are ordered on the basis of their compositional similarity. Phase compositions and rock-surface properties are used to calculate wettability and contact angles. The model is tuned to measured two-phase relative permeability curves with very few tuning parameters and then is used to predict relative permeability away from the measured experimental data. The model is applicable to all flow in porous-media processes, but is especially important for low-salinity polymer, surfactant, miscible gas, and water-alternating-gas (WAG) flooding. The results show excellent ability to match measured data, and to predict observed trends in hysteresis and oil-saturation trapping, including those from Land's model and for a wide range in wettability. The results also show that relative permeabilities are continuous at critical points and yield a physically correct numerical solution when incorporated within a compositional simulator (PennSim 2013). The model has very few tuning parameters, and the parameters are directly related to physical properties of rock and fluid, which can be measured. The new model also offers the potential for incorporating results from computed-tomography (CT) scans and pore-network models to determine some input parameters for the new EOS.
Modeling and Analysis on the Effect of Two-Phase Flow on Wormhole Propagation in Carbonate Acidizing
Authors: Wei W.. , Varavei A.. , Sepehrnoori K.. 
Published: August 2017

Summary
Matrix acidizing is a stimulation technique aiming at improving formation permeability or bypassing damaged zones. In this process, acid is injected through the well into the wellbore vicinity to dissolve the rock. For either production or injection wells, the formation may contain multiple phases (oil and water) near the wellbore region when acid treatment begins. In this paper, a two-phase two-scale continuum model is developed to simulate wormhole propagation under radial coordinates. The model describes the mechanisms of convection, dispersion, and reaction in two-phase flow during matrix acidizing. We have validated the simulation model with two methods: one is to compare with the previous simulation results; the other is to compare with the analytical solution. We have investigated conditions that will affect the wormhole-propagation process, including rock wettability, oil viscosity, and initial oil saturation. It is found that the water/oil mobility ratio is a key factor that affects acidizing efficiency. In addition, we have proposed a new criterion for acid breakthrough because the pressure response is affected not only by reaction, but also by overall mobility change in the formation. The traditional criterion for the single-phase model is no longer applicable to the current two-phase model. The results show that adverse water/oil mobility ratio leads to a higher efficiency for wormhole breakthrough. In carbonate reservoirs with heterogeneity, water/oil displacement and wormhole propagation contribute to narrower, less-branched channels. For the first time, it is possible to simulate formations with multiple phases during carbonate acidizing. The presented model improves our understanding in the optimization of carbonate acidizing.
A Proposed Systematic Approach for Experimental Asphaltene Investigation: An Oil-Reservoir Case Study
Authors: Bagherzadeh Hadi , Golghanddashti Hassan , Shahrabadi Abbas 
Published: August 2017

Summary
Asphaltene precipitation and deposition are major flow-assurance issues that can reduce or completely stop the production of oil wells. To evaluate the severity of asphaltene problems in an oil reservoir, various laboratory tests should be planned. In this paper, a stepwise experimental approach is proposed to assess the asphaltene issue in oil reservoirs. Taking representative oil samples downhole is the first step to accurate experimental investigations. In case the sample does not represent the reservoir status correctly, all the laboratory data—even with accurate measurement—could be misleading. Then, reservoir-fluid characterization and saturate/aromatic/resin/asphaltene (SARA) analysis should be performed for primary evaluations and asphaltene-stability screening. Asphaltene-onset-pressure (AOP) measurement indicates the point at which asphaltene comes out of the solution. After that, assessment of asphaltene-precipitation potential depending on production scenarios (e.g., depletion or gas injection) at reservoir conditions should be performed. Finally, the effect of deposited asphaltene should be characterized in the presence of porous media in terms of deposition amount and its consequent permeability impairment. Eventually, this approach is used for an Iranian oil reservoir.
This experimental approach, along with modeling and simulation of asphaltene precipitation and deposition, can be used as the best practice for assessing the asphaltene issue in oil reservoirs.

Published: August 2017

Abstract
In order to optimize the operating conditions for a combined polyaluminum chloride (PACl) coagulation/flocculation and ultrafiltration process for treating potable water, the main, second order and interaction effects of PACl dose and flocculation retention time (FRT) on permeate turbidity, UV254 and membrane permeability were investigated using a 100 kDa hollow fiber membrane operated in the dead-end mode. A multilevel factorial design was used to determine the relevant ranges of the two factors for optimization. A 22 central composite design (CCD) was then used to develop mathematical correlation models for the optimum operating conditions. The main effect of PACl dose was the most significant factor on all the responses. For permeability, both the main effect of FRT and FRT–PACl dose interactions were found to be insignificant. The optimum PACl dose and FRT for the feed water were 20 mg/L and 14 min, respectively. Corresponding permeate turbidity, UV254 and permeability were 0.15 ± 0.01 NTU, 0.003 ± 0.001 cm−1 and 62.0 ± 9.52 Lm−2 h−1 bar−1, respectively. Experimental validation runs confirmed the reliability of the predicted optimal conditions thus implying that CCD models can be used to predict/optimize the quality and quantity of permeate from hybrid coagulation–ultrafiltration systems for potable water treatment.
The Role of Oxidative Stress Modulators in Breast Cancer
Authors: Gurer-Orhan Hande , Ince Elif , Konyar Dilan , Saso Luciano , Suzen Sibel 
Published: August 2017

Background:
Latest data from International Agency for Cancer Research shows that
breast cancer is the leading cancer site in women and is the leading cause of death among female
cancers. Induction of reactive oxygen species (ROS) and oxidative stress as a consequence of impaired
balance between prooxidants and antioxidants are suggested to be involved in induction and
progression of breast cancer. Cancer cells are found to exhibit higher levels of ROS compared to
normal cells. However increased antioxidant defence which balances the oxidative status within the
cancer cells suggests that high ROS levels may prevent tumorigenesis via various mechanisms.
These contradictory roles of ROS and oxidative stress in breast cancer let scientists investigate potential
oxidative stress modulators as anticancer strategies.

Conclusions:
In the present review we address the mechanisms of ROS production in breast cancer
cells, the role of impaired oxidative status as well as the benefits of introducing oxidative stress
modulators in therapeutic strategies in breast cancer. This review is focusing more on melatonin
which we have been working on during the last decade. Our data, in accordance with the literature,
suggest an important role for melatonin in breast cancer prevention and adjuvant therapy.
Cataract Surgery in Patients with Keratoconus: Pearls and Pitfalls
Authors: Aiello F. , Nasser QJ , Nucci C. , Angunawela R.I. , Gatzioufas Z. , Maurino V. 
Published: August 2017

Background:
Keratoconus (KC) is a common ectatic disorder resulting in progressive corneal thinning and irregular astigmatism. It has been observed that patients affected by KC are more likely to develop lens opacities earlier compared to non-keratoconic patients.

Objective:
Intraocular lens (IOL) selection and refractive outcome prediction are among a number of factors that can make cataract surgery in keratoconic patients challenging. Accurate biometry is often difficult to obtain due to unreliable K measurements and lack of dedicated biometric formulae. The use of toric IOLs has also been investigated.

Conclusions:
Determining the stage of KC, pre-operative patient counselling and the preferred method of refractive correction are all crucial to obtain successful postoperative outcomes and good patient satisfaction. The use of toric IOLs can achieve good results only in selected low-grade keratoconic eyes.
