Application of the Random Forest classification method for facies zoning according to seismic data
Authors: Butorin Aleksander V. , Mokhov Grigory V.
Published: October 2021

Background. Facial zoning based on seismic data is an important task of dynamic analysis. There are numerous approaches of solving this problem using various algorithms. The most common method is clustering by reflection shape. This approach belongs to unsupervised learning algorithms, due to the mapping of seismic facies is based on the internal data structure and the key feature is the change in the wave packet within the target interval. The disadvantage of this method is requirement of further tying clustering results and geological information. Another way of directed solution of this problem is the use of supervised learning algorithms. This category includes various classification methods that relate to the category of machine learning. In comparison to traditional approaches of seismic facial analysis, this method accounts geological information at the computation stage. Aim. This paper considers the results of a research carried out with the study of the facies structure of the Tyumen formation at a group of fields in the Khanty-Mansiysk Autonomous Region. The Tyumen formation is characterized by the predominance of channel facies associated with the development of complex river systems, which are clearly observed in the dynamic characteristics of the wave field. A complicating factor in the study of these deposits is the rather low coverage of well data, which makes difficult the geological interpretation of the results obtained. Materials and methods. The authors used the Random Forest classification method to deal with the assigned task. The application of the method is considered on the cluster consisting of three seismic surveys obtained at different times. For training, expert marking by area was used based on the distribution of amplitudes along the reflecting horizon. Results. As a result of the research, a probabilistic assessment of the distribution of channel facies was obtained, that is related to the perspective of this type of deposits in the study area. Thus, the authors have developed a methodology that gives an opportunity to obtain an estimate of the probability of the presence of a certain facies using seismic data. Conclusions. The performed study shows the possibility of using the Random Forest classification method to solve the problem of facial zoning.
Optimization model of material balance for reservoir energy survey analysis and control
Authors: Sidelnikov Konstantin A. , Tsepelev Vyacheslav P. , Kolida Aleksandr Ya.
Published: October 2021

Introduction. When monitoring the development of hydrocarbon fields, the energy state of the reservoirs is monitored. An inaccurate understanding of the current distribution of reservoir pressure leads to the wrong strategy for the development of residual oil reserves. Isobar maps are constructed to assess reservoir pressure for productive formation. The simplest and most common method of map generation (by interpolating the values of the measurements) has a high sensitivity to the coverage of the well stock by well tests and does not take into account the dynamics and compensation of fluid withdrawals. To eliminate these shortcomings, it is proposed to use the method of multi-tank material balance. Objectives. The purpose of the work is to show the possibility of using the multi-tank material balance method (MMB) to reduce the risks related to low current reservoir pressure at the stage of well workover planning under conditions of limitations on the number and duration of well tests and taking into account the history of production / injection, as well as to predict the dynamics of reservoir pressure in the drainage area. Methods. In the MMB model, for each well, its own block (tank) is specified, for which the mathematical balance equation is drawn up, taking into account the crossflow between the blocks. The transmissibility values are obtained iteratively by numerically solving the problem of minimizing the loss function of the discrepancy between the calculated reservoir and bottom hole pressures and their actual values. Results. The paper provides examples of good convergence of the calculated pressures by the MMB method to the actual build-up test results at the wells of the Ural-Volga fields. The possibility of predictive calculations to optimize the reservoir pressure maintenance system is shown. The practical advantages of the method are: relative simplicity of model, automated adjustment of interblock transmissibility. Discussion. The field of application of the MMB method is determined by the tasks in which it is necessary to determine the reservoir pressure in conditions of a lack of fresh measurements. The MMB methodology is applicable to assess reservoir pressure in order to remove risks before well workovers, as well as to predict the optimization of the reservoir pressure maintenance system.
Measurement Report: Strong Valley Wind Events during the International Collaborative Experiment – PyeongChang 2018 Olympic and Paralympic Winter Games Project
Authors: Joe Paul , Lee Gyuwon , Kim Kwonil
Published: October 2021

Abstract. Strong gusty wind events were responsible for some of the poor performances of competitors and resulted in schedule changes during the PyeongChang 2018 Olympic and Paralympic Winter Games. Three events at two venues were investigated to document and articulate the wind forecasting and nowcasting challenges. Upper air analysis showed that the Games were dominated by northwesterly synoptic flow. Froude and Reynolds number analyses indicated that vortex shedding or wake turbulence were the dominant mechanisms in the lee of the mountains where the free-style competitions were conducted. Three types of wind data (10 and 1 min averages plus 1 minute maximums) from automatic weather stations that were reported every minute were analyzed using advanced techniques (Hovmueller, wavelet and eigen analysis frequency estimation). For the two days of Event 1, the conditions were well mixed throughout the day and night. For the other events, diurnal variations were observed with a stable atmosphere at night, well mixed in the afternoon and with 2–4 hour transition periods in the morning and evenings. Turbulence was best portrayed using wavelet analysis and vortex shedding was best portrayed using the eigen analysis frequency estimation method. The latter revealed dominant frequencies, presumably associated with vortex shedding with periodicities of 20 to 90 minutes. Nowcast implications are discussed.
Assessing vehicle fuel efficiency using a dense network of CO2 observations

Published: October 2021

Abstract. Transportation represents the largest sector of anthropogenic CO2 emissions in urban areas. Timely reductions in urban transportation emissions are critical to reaching climate goals set by international treaties, national policies, and local governments. Transportation emissions also remain one of the largest contributors to both poor air quality (AQ) and to inequities in AQ exposure. As municipal and regional governments create policy targeted at reducing transportation emissions, the ability to evaluate the efficacy of such emission reduction strategies at the spatial and temporal scales of neighborhoods is increasingly important. However, the current state of the art in emissions monitoring does not provide the temporal, sectoral, or spatial resolution necessary to track changes in emissions and provide feedback on the efficacy of such policies at a neighborhood scale. The BErkeley Air Quality and CO2 Network (BEACO2N) has previously been shown to provide constraints on emissions from the vehicle sector in aggregate over a ~1300 km2 multi-city spatial domain. Here, we focus on a 5 km, high volume, stretch of highway in the SF Bay area. We show that inversion of the BEACO2N measurements can be used to understand two factors that affect fuel efficiency: vehicle speed and fleet composition. The CO2 emission rate of the average vehicle (g/vkm) are shown to vary by as much as 27 % at different times of a typical weekday because of changes in vehicle speed and fleet composition. The BEACO2N-derived emissions estimates are consistent to within ~3 % of estimates derived from publicly available measures of vehicle type, number, and speed, providing direct observational support for the accuracy of the Emissions FACtor model (EMFAC) of vehicle fuel efficiency.
Surface deposition of marine fog and its treatment in the Weather Research and Forecasting (WRF) model

Published: October 2021

Abstract. There have been many studies of marine fog, some using Weather Research and Forecasting (WRF) and other models. Several model studies report overpredictions of near-surface liquid water content (Qc), leading to visibility estimates that are too low. This study has found the same. One possible cause of this overestimation could be the treatment of a surface deposition rate of fog droplets at the underlying water surface. Most models, including the Advanced Research Weather Research and Forecasting (WRF-ARW) Model, available from the National Center for Atmospheric Research (NCAR), take account of gravitational settling of cloud droplets throughout the domain and at the surface. However, there should be an additional deposition as turbulence causes fog droplets to collide and coalesce with the water surface. A water surface, or any wet surface, can then be an effective sink for fog water droplets. This process can be parameterized as an additional deposition velocity with a model that could be based on a roughness length for water droplets, z0c, that may be significantly larger than the roughness length for water vapour, z0q. This can be implemented in WRF either as a variant of the Katata scheme for deposition to vegetation or via direct modifications in boundary-layer modules.
Co-observation of strongly convective precipitation using VHF atmospheric radar and dual-polarized microwave radiometer during a typhoon passage
Authors: Tsai Shih-Chiao , Chu Yen-Hsyang , Chen Jenn-Shyong
Published: October 2021

Abstract. The Chung-Li very-high-frequency (VHF at 52 MHz) atmospheric radar and a dual-polarized microwave radiometer were operated collaboratively to investigate strongly convective precipitation while the typhoon Trami just passed through the Taiwan in Aug, 2013. First, respective Doppler velocities of clear-air and precipitation echoes were identified automatically by the VHF radar as clearly as possible. Two approaches were designed for this purpose: contour-based and peak-finding processes. The two approaches initially determined some major spectral centers or peaks, which were usually redundant, and then proper sifting and clustering were performed for the redundant spectral centers or peaks to yield several mean locations of Doppler velocities for profiling. The outcomes of the two approaches were consistent in general. With the estimated Doppler velocities, a tracing process was developed for Doppler profiling, in which Doppler velocity shear was one of the significant criteria in the tracing process. The radar echoes collected by the VHF radar during rainy and strongly convective atmosphere have been investigated to validate the two approaches and the tracing process. About 98 % of the tracings could identify the Doppler profiles of clear air and precipitation, even the atmosphere was disturbed severely. The radar spectral parameters, Doppler profiles, and the information from a dual-polarized microwave radiometer as well as the simulation of weather model, were examined jointly. It signified that strong updraft and turbulent atmosphere could bring the liquid water to the height above the melting layer, and then the Bergeron effect and coalescence process on formation of ice crystal and graupel above the height of the melting layer occurred accordingly.
Bacteriohopanetetrol-x: constraining its application as a lipid biomarker for marine anammox using the water column oxygen gradient of the Benguela upwelling system
Authors: van Kemenade Zoë Rebecca , Villanueva Laura , Hopmans Ellen C. , Kraal Peter , Witte Harry J. , Sinninghe Damsté Jaap S. , Rush Darci
Published: October 2021

Abstract. Interpreting lipid biomarkers in the sediment archive requires a good understanding of their application and limitations in modern systems. Recently it was discovered that marine bacteria performing anaerobic ammonium oxidation (anammox), belonging to the genus Ca. Scalindua, uniquely synthesize a stereoisomer of bacteriohopanetetrol (‘BHT-x’). The ratio of BHT-x over total bacteriohopanetetrol (BHT; ubiquitously synthesized by diverse bacteria) has been suggested as a proxy for water column anoxia. As BHT has been found in sediments over 50 Myr old, BHT-x has the potential to complement and extend the sedimentary biomarker record of marine anammox, conventionally constructed using ladderane lipids. Yet, little is known about the distribution of BHT-x in relation to the distribution of ladderanes and to the genetic evidence of Ca. Scalindua in modern marine systems. Here, we investigate the distribution of BHT-x and the application of the BHT-x ratio in relation to distributions of intact polar (IPL) ladderane lipids, ladderane fatty acids (FAs) and Ca. Scalindua 16S rRNA genes in suspended particulate matter (SPM) from the water column, sampled across a large oxygen gradient in the Benguela upwelling system (BUS). In BUS SPM, high BHT-x abundances were constrained to the oxygen deficient zone on the continental shelf (at [O2] < 45 µmol L−1, in all but one case). High BHT-x abundances co-occurred with high abundances of the Ca. Scalindua 16S rRNA gene (relative to the total number of bacterial 16S rRNA genes) and ladderane IPLs. At shelf stations with [O2] > 50 µmol L−1, the BHT-x ratio was < 0.04 (in all but one case). In apparent contradiction, ladderane FAs and low abundances of BHT and BHT-x (resulting in BHT-x ratio’s > 0.04) were also detected in oxygenated offshore waters ([O2] up to 180 µmol L−1), whereas ladderane IPLs were undetected. NL5-derived temperatures suggested that ladderane FAs in the offshore waters were not synthesized in situ but derived from warmer shelf waters. Thus, in sedimentary archives of systems with known lateral organic matter transport, such as the BUS, relative BHT and BHT-x abundances should be carefully considered. In such systems, a higher BHT-x ratio may act as a safer threshold for deoxygenation and/or Ca. Scalindua presence: in the BUS, at [O2] > 50 µmol L−1, the BHT-x ratio was < 0.18 at both off -and onshore sites (in all but one case) and a ratio > 0.18 corresponded in all cases (except one) with the presence of Ca. Scalindua 16S rRNA genes. Lastly, when investigating in situ anammox, we highlight the importance of using ladderane IPLs over BHT-x and/or ladderane FAs; these latter compounds are more recalcitrant and may derive from transported fossil anammox bacteria remnants.
Hyperspectral reflectance spectra of floating matters derived from HICO observations
Authors: Hu Chuanmin
Published: October 2021

Abstract. Using data collected by the Hyperspectral Imager for the Coastal Ocean (HICO) on the International Space Station between 2010–2014, hyperspectral reflectance of various floating matters in global oceans and lakes are derived for the spectral range of 400–800 nm. Specifically, the entire HICO archive of 9,411 scenes is first visually inspected to identify suspicious image slicks. Then, a nearest-neighboring atmospheric correction is used to derive surface reflectance of slick pixels. Finally, a spectral unmixing scheme is used to derive the reflectance spectra of floating matters. Analysis of the spectral shapes of these various floating matters (macroalgae, microalgae, organic particles, whitecaps) through the use of a Spectral Angle Mapper (SAM) index indicates that they can mostly be distinguished from each other without the need of ancillary information. Such reflectance spectra from the consistent 90-m resolution HICO observations are expected to provide spectral endmembers to differentiate and quantify the various floating matters from existing multi-band satellite sensors and future hyperspectral satellite missions such as NASA’s Plankton, Aerosol, Cloud, and ocean Ecosystem (PACE) mission and Surface Biology and Geology (SBG) mission.

Abstract. Wintertime convection in the North Atlantic Ocean is a key component of the global climate as it produces dense waters at high latitudes that flow
equatorward as part of the Atlantic Meridional Overturning Circulation (AMOC). Recent work has highlighted the dominant role of the Irminger and
Iceland basins in the production of North Atlantic Deep Water. Dense water formation in these basins is mainly explained by buoyancy forcing that
transforms surface waters to the deep waters of the AMOC lower limb. Air–sea fluxes and the ocean surface density field are both key determinants of the buoyancy-driven transformation. We analyze these contributions to the transformation in order to better understand the connection between atmospheric forcing and the densification of surface water. More precisely, we study the impact of air–sea fluxes and the ocean surface density field on the transformation of subpolar mode water (SPMW) in the Iceland Basin, a water mass that “pre-conditions” dense water formation downstream. Analyses using 40 years of observations (1980–2019) reveal that the variance in SPMW transformation is mainly influenced by the
variance in density at the ocean surface. This surface density is set by a combination of advection, wind-driven upwelling and surface fluxes. Our
study shows that the latter explains ∼ 30 % of the variance in outcrop area as expressed by the surface area between the outcropped SPMW
isopycnals. The key role of the surface density in SPMW transformation partly explains the unusually large SPMW transformation in winter 2014–2015 over the Iceland Basin.
Az élelmiszeripari nanotechnológia fogyasztói elfogadása
Authors: Farkas Noémi Dóra , Kiss Marietta

Napjainkban az élelmiszeripari fejlesztéseket jellemzően két megatrend irányítja: a globális felmelegedés és a táplálkozással szorosan összefüggő hátrányos egészségügyi következmények (civilizációs betegségek, túlsúly, éhezés, elöregedő társadalom) kiküszöbölésének igénye. Ennek következtében a fogyasztói preferenciák is módosultak, hiszen az olyan „mindennapos” igények, mint az élelmiszerek elfogadható ára, kellemes íze és biztonságos fogyaszthatósága, továbbá az, hogy egy élelmiszer pusztán fiziológiai szükségleteket elégítsen ki, napjainkra alapvető követelménnyé változtak, és nem jelentenek kimutatható piaci előnyt. Egy termék piaci szereplése várhatóan akkor lesz sikeres, ha a fentieken túl összetevői és élettani hatásai a fogyasztó közérzetét, egészségi állapotát, fizikai teljesítőképességét bizonyíthatóan növelik. Az egyik legnagyobb iramban fejlődő tudományterület ma a nanotechnológia, amelynek számos alkalmazása létezik az élelmiszeriparban. Annak ellenére, hogy ez a technológia eddig nem tapasztalt előnyökhöz juttatja a fogyasztókat és számos globális problémára jelenthet megoldást, a nanoélelmiszerek számos kockázatot és veszélyt is hordoznak magukban. Habár a nanotechnológia még sokak számára ismeretlen, a megkérdezettek körében a vásárlási hajlandóság igen magas, ha a technológia révén az élelmiszer valamely tulajdonsága javul. A fogyasztókat attitűdjük alapján két jól elkülöníthető csoportra lehet osztani: azokra, akik a lehetséges előnyöket és hátrányokat egymástól gyökeresen különböző módon látják.
