Can changes in hoof wall temperature and digital pulse pressure be used to predict laminitis onset?
Authors: Brown Honoria 
Published: October 2019

PICO question
In horses and ponies at risk of laminitis, does the use of hoof wall temperature and digital pulse pressure as diagnostic techniques for acute laminitis provide a method of detecting acute laminitis in the prodromal stage?
Clinical bottom line

A palpable bilateral increase in forelimb hoof temperature maintained for longer than half a day may indicate that the horse is 18–­24 hours from acute laminitis onset.
A period of increased digital pulse may also be expected up to 11 hours prior to onset.
Further studies using larger and more representative cohorts are required to confirm the accuracy of the times at which such changes can be expected.

In modern food industry in the innovative technologies development are frequently used physical methods for processing raw materials and food products. However, an analysis of the literature has shown that the mechanisms of the microwave and infrared (IR) energy influence on the nutritional value of raw materials and food products are not understood in full. At the same time, the processing of vegetable raw materials should be carried out using technologies are provided the maximum possible extraction from it of valuable nutrients, which are contained in it in optimal ratios and easily digestible form. A feature of the developed technology of carrot powder is the using of microwave heating for pretreatment of refuse to increase the antioxidant value on account of increasing in the content of free water-soluble antioxidants as a result of an increasing of cellular permeability and the effect of plasmolysis. For carrots refuse was determined a rational microwave treatment regime, which provides a maximum increasing of total content of antioxidants (38.0 mg/100 g or 191.0 mg/100 g solid): power – 800 W, time – 180 s, specific work – 720 W/ g?s, the heating temperature of refuse is 95 ?. Infrared drying used for intensification of refuse drying at a temperature of 60–65 ? for 220 minutes to a moisture content of 7.5–8%. As a result of infrared drying, the preservation of antioxidants are increases by an average of 12.5% compared with the convective drying method, which may be due to a decrease of drying time by an average of 1.7 times. Carrot powder made by the new technology with using of microwave accorded to the safety requirements, which indicates the possibility of its using in the production of food for various purposes. Thus, the developed technology allows to obtain additional products from the secondary raw materials of juice production such as powder with high antioxidant value.

The unstable development of the economy of the vast majority of Russian regions and unstable indicators in modern conditions require the establishment and determination of the causes of the observed negative events. This situation is relevant at the regional level, where, in addition to the devastating consequences, the inconsistency of state policy in the field of institutional Economics has created a General lag in the pace of socio-economic development. Based on this, the timeliness and relevance of the consideration of improving the instrumental forms of ensuring the spatially-uniform development of the regions is that the current stage of development of the regional economic level is identified by us with the increasing center-periphery differentiation. The processes of its growth, which are formed under the influence of evolutionary-acquired and inertial-hereditary factors, negatively affect the pace of socio-economic development of peripheral and semi-peripheral territories, do not allow to develop the real sector of the territorial economy, to improve the level and quality of life of the population of localities. In this regard, it seems that the solution of scientific problems of finding new and improving existing instrumental forms of spatially-uniform regional development is relevant in theoretical, methodological and applied aspects of the element of scientific support for the development of the regional economy, its subsystems and components, and the study is desirable to focus on the growth of methodological principles of spatial development of most regions operating in the conditions of center-periphery stratification, as well as the argument of practical recommendations for their depolarization on the principles of improving the organizational and economic tools, as well as methods of analysis and evaluation of the spatial development of the region.

Velocity Building Strategy for Imaging Deep Low Relief Structure in Tarim Basin
Authors: Zhao Mingqiu , Yuan Liao , Li Qing 
Published: October 2019

Abstract
The gas reservoirs in the northern Tarim basin in the western China are situated in the deep (4-5km) low relief structure. The complex near surface geology, e.g. rugged terrain, meandering rivers, channels and alluvial fans, results in a very complex near surface velocity structure, which has been a huge challenge for advanced anisotropic migration algorithms. The local but frequent variation due to heterogeneity or faulting in the thick overburden also has a significant impact on the structural shape and the depth accuracy of the deep reservoir. Recent drilling results show multiple cases of seismic-well depth reversal in the Hongqi gas field in Tarim basin. We explored the fundamental issues behind the reversed seismic-well depth relationship and concluded that conventional velocity building procedure could not capture the local but quick change in the overburden. We employed different velocity building and imaging strategies: (1) true ground surface or optimized ground surface using small grid smoothing as the top of velocity model and migration datum, (2) velocity for different depth levels from the near surface (0-300m), to the shallow depth (~300-~3000m), and to further deep intervals (&gt;3000m) using different techniques and constraints, and (3) anisotropic parameters are updated during grid reflection tomography for the specific media in this field so as to enable an anisotropic PSDM. The resulting composite velocities successfully solved the seismic-well depth reversal in the Hongqi gas field.

Published: October 2019

Abstract
Pulsed neutron log provides a valuable method of evaluating cased hole formations. It is commonly used to monitor reservoir performance and depletion over a long period of time. The tool can be used to monitor sweep efficiency during waterflooding and enhanced oil recovery stages. It can provide valuable data that can be used to fine-tune the simulation model predictions.
Pulsed neutron tools are commonly run, in either capture or inelastic modes, to estimate time-lapse fluid saturation changes behind the casing they consist of one neutron generator and a number of gamma ray detectors at different distances from the neutron generator. The tools are run in different modes to investigate front movement and 2-phase/3-phase saturation profile under challenging borehole conditions.
The older generation 2-detectors tool is highly affected by the borehole environment, and therefore saturation. The two new generation 3-detectors and 4-detectors tools seem better in detecting and quantifying the fluid saturation. Subsequently, the 3-detectors tool is seemingly the best in terms of delivering robust answers in complex and unknown borehole conditions.
The log results from the new generation tools were useful for tracking the 2-phase/3-phase fluid front movement, identifying swept intervals. This paper compare the design and implementation of the different pulsed neutron tools generations, limitations and operational issues, and log results interpretation
An Artificial Intelligence Approach to Predict Molar Compositions of Reservoir Fluid Components
Authors: AlMatouq Hana , Alabbad Mohammed , Anifowose Fatai 
Published: October 2019

Abstract
Reservoir fluid composition is an essential element in the planning and development of petroleum fields. Experimental analysis and computational modeling are performed on reservoir fluid samples to find molar compositions and to understand fluid behavior throughout the life cycle of the reservoir. There are various computational practices to simulate reservoir fluids behavior applying equation of states and other approaches. However, with the aid of the 4th industrial revolution, and with many successful applications of artificial intelligence in the oil and gas industry, an artificial neural network model was built to predict molar compositions for different reservoir fluids.
The expert system described in this work is a tool which can be used to predict molar compositions of reservoir fluids. One of the main challenges in predicting fluid compositions is its complexity and its wide differences. There are huge composition variations between different formations and sometimes within the same formation due to possible existing compartments in the reservoir. Moreover, the compositions vary with several factors such as location, reservoir conditions, and time. Therefore, the inputs to the ANN model should include well location 3D coordinates, reservoir conditions, API gravity, gas specific gravity, average molecular weight, sampling date, as well as reservoir and field information.
The ANN model was trained based on historical experimental data of fluids from different fields and formations. Different cases and error analysis were performed to optimize the prediction accuracy of the developed tool. A feedforward back-propagation algorithm was applied in building the model. Results indicated that a more accurate model could be obtained without grouping any hydrocarbon components. A successful prediction of molar composition was achieved using the built ANN model. This method can add a great value to the reservoir characterization process as the fluid molar composition can now be predicted using simple measurements of fluid properties and other reservoir data that can be easily obtained.
Introducing this ANN model into the process of fluid compositional analysis will optimize the operational process by reducing the time and cost associated with the experimental analysis.
Macroscopic Scale Interactions of Smartwater with Alkaline Chemicals for Enhanced Oil Recovery in Carbonates

Abstract
SmartWater flooding through tuning of injection water salinity and ionic composition is recently gaining good attention for enhanced oil recovery (EOR) in carbonates. The development of new hybrid recovery methods by capitalizing on the synergy with SmartWater can provide one potential optimization route for achieving more economic and effective EOR applications in the field.
In this experimental investigation, we evaluated the synergy of alkali with SmartWater through interfacial tension and contact angle measurements. These measurements were performed at reservoir conditions (2,500 psi and 70°C) using the crude oil and rock substrates from a carbonate reservoir. The high pH common alkali (NaOH) was used at dilute concentrations of 0.1 wt% in two different SmartWater recipes at a fixed low salinity (5,760 ppm TDS). The SmartWater recipes chosen include; 10-times reduced salinity seawater and low salinity water enriched with sulfates and without the divalent cations together with the seawater as baseline.
The contact angle results with high salinity seawater showed the strongly oil-wet behavior (140°) for a carbonate surface, which was favorably altered toward an intermediate-wet state (90°) with SmartWater recipes. The addition of alkali to 10-times reduced salinity seawater increased the contact angle to 152° due to alkali precipitate (formed by the reaction with divalent cations) preventing the interaction of key ions in the SmartWater with carbonate rock surface. A significant shift in the wettability toward a water - wet state (70°) was obtained by the addition of alkali to the SmartWater-enriched with sulfates to confirm the major role of pH on wettability alteration. In addition a reduction in the interfacial tension from 16.6 mN/m to about 7.2 mN/m was achieved by the addition of alkali to the SmartWater-enriched with sulfates in comparison to seawater, as a result of favorable alkali interactions with carboxylic acid groups present in the crude oil. The compounding of these beneficial wettability alteration and interfacial tension reduction effects observed with alkaline chemicals would further reduce capillary forces to mobilize relatively higher amounts of waterflood residual oil in carbonates.
This study is of practical significance as it successfully demonstrates the positive impact of combining SmartWater with alkaline chemicals for both wettability alteration and IFT reduction in carbonates at reservoir conditions. It also opens up a new avenue to exploit the use of synergistic alkaline based hybrid recovery processes for efficient and economical EOR applications in carbonate reservoirs.
The Future of Nonmetallic Composite Materials in Upstream Applications

Published: October 2019

AbstractCorrosion in oil and gas operations is generally caused by water, carbon dioxide (CO2) and hydrogen sulfide (H2S), and can be aggravated in downhole applications where high temperatures combination with H2S introduce other challenges related to corrosion and iron sulfide (FeS) scale formation. The repair costs from corrosion attacks are very high and associated failures have effects on plant production rates and process integrity. To overcome this existing problem in upstream, nonmetallic composite materials were introduced for drilling, tubular and completions in high risk, corrosive environments. The goal being to increase the well life cycle and minimize the effect of corrosion, scale and friction in carbon steel tubulars. The new proposed materials have light weight, high strength, and superior fatigue resistance in addition to an outstanding corrosion resistance that is able to surpass many metallic materials.The economic analysis shows that utilization of nonmetallic tubulars and internal linings will yield substantial life cycle cost saving per well mainly due to the elimination of workover operations. However, with these advantages, composite materials pose several challenges such as single source provision, high initial cost of raw materials, the manufacturing process and the limitation of standards. As results, the polymer and composite solutions for upstream oil and gas are still very limited even in targeting low risk applications such as low temperature and pressure scenarios. Therefore, research & development (R&D) efforts are ongoing to increase the operation envelope and introduce cost effective raw materials for high-pressure, high temperature (HPHT) subsurface applications.The present paper highlights practical examples of nonmetallic materials selection and qualification for upstream water injection/producer and hydrocarbon wells. Several future NM applications in upstream will be summarized. Challenges and R&D forward strategies are presented in order to expand the operation envelope of current materials and increase NM deployment to more complex wells, i.e., extended reach drilling (ERD).

Abstract
Drilling to the targeted depth of a well can be a challenge, considering the problems that may arise in the form of wellbore instability, mud losses, and/or differential sticking. The objective was to successfully drill a first-time implementation of an Oil-Based Mud (OBM) system with 60:40 Oil-Water Ratio (OWR).
The OBM system was maintained within the specified parameters in terms of mud weight, viscosity, and fluid loss. The addition of primary and secondary emulsifiers in the system enhanced electric stability (ES). Moreover, solid control equipment will be monitored continuously for immediate action if necessary. Contingency plan and a surplus of chemicals will be provided to ensure a smooth drilling and a swift movement of operations.
A fluid system was designed after extensive laboratory tests to analyze the optimal approach to drill using the first-time application of 60:40 OWR mud. It reduces the use of Diesel consumption by 26% in total OBM formulation, lowers the percentage of Low Gravity Solids (LGS) compared to the 80:20 OWR mud, and decreases the impact on the environment. Furthermore, the OBM was then reused in consequent wells with the addition of emulsifiers to reduce the cost.
This paper presents successful first-time applications of the 60:40 OWR fluid till the targeted lower Burgan formation, interbedded sandstone and shale formation. A complete laboratory analysis comparison between previous wells drilled and the current application indicates no difficulties were faced.
