Nonparametric-copula-entropy and network deconvolution method for causal discovery in complex manufacturing systems

To clarify the causality among process parameters is a core issue of data-driven production performance analysis and product quality optimization. The difficulty lies in accurately measuring and distinguishing direct and indirect associations of complex manufacturing systems. In this work, the nonparametric-copula-entropy and network deconvolution method is proposed for causal discovery in complex manufacturing systems. Firstly, based on copula theory and kernel density estimation method, the nonparametric-copula-entropy is introduced to improve the accuracy of association measurement between parameters, and its superiority is verified by comparing with the results of different association measurement methods. Then, the global association matrix is constructed by the nonparametric-copula-entropy, and network deconvolution method is employed to extract the direct information from the global association matrix. The proposed method is tested by using an open gene expression dataset. Finally, as an experimental application, the causal analysis for a diesel engine production line is carried out by the proposed method. The results show that the proposed method can reveal causal relationship between process parameters and quality parameters in the diesel engine production line well, which provide theoretical guidance and implementation approach for the optimal control of complex manufacturing system.

Research on Von Bertalanffy model and its application for predicting recoverable reserves and production of oilfield

Water drive type curves are simple, convenient and practical in reservoir engineering, which is widely used in reservoir production performance analysis. However, the commonly used water drive type curve can only draw one curve between water cut and recoverable reserves recovery degree, which greatly limits the application range of water drive curve. At the same time, the fitting of straight line section of water drive type curve is often affected by artificial selection, and the error is large. In order to better describe and reflect the rising law of water cut in different type reservoirs, the new water drive type curve is established, and the relationships between water cut and cumulative production, water cut and recovery degree of recoverable reserves are derived. Through MATLAB software programming and multi parameter fitting method, the parameters in the new water drive type curve can be easily calculated. The f w-R * curve shape of the new model includes convex curve, concave curve and S-shape curve. The new water drive type curve is applied to two actual reservoirs. The new curve fits well with the low water cut stage of the Baolang oilfield, and the error is small, which can be used to predict the future production performance of the oilfield. At the same time, the new water drive type curve is consistent with the change trend of the whole production stage of the Saertu oilfield, and the error is small, too. which can be used for the prediction of the whole production period and high water cut stage of the reservoir. The new model expands the application range of water drive type curve and provides reference for production performance prediction of other similar oilfields.

Twelve years of unconventional oil and gas development: production performance and economic analysis

Unconventional formations have been actively developed in the US since 2008. However, it is challenging to quantify the impact of technological advancement and geology on production. In addition, the economics of unconventionals is not well-understood. In this paper, we studied five major unconventional formations in the US: the Bakken, Eagleford, Haynesville, Marcellus, and Wolfcamp formations. We used historical data to quantify the impact of technological and geological variations on production. To accomplish this, we identified four phases of unconventional development over the past 12 years during which drilling and completion technology, initial investment, and commodity prices were similar: Phases 1–4. Using statistical analysis, we compared well performance of each phase. Then, we generated type curves for each phase for economic studies. Initial analysis shows that between January 2008 and December 2019, 60,611 horizontal wells were completed in these formations, producing about 8.185 billion barrels of oil, 90 trillion cubic feet of gas, and generating an estimated $816 billion in gross revenue. For the statistical analysis, the level of uncertainty ( $${P}_{10}/{P}_{90}$$ ratio) reduced from Phase 1 to Phase 4 across all formations, suggesting consistent improvements in well productivity over time while county-level analysis shows spatial disparity in well performance. We infer that technology drives temporal changes while geology drives spatial differences in well performance. From economic analysis, Phase 4 type wells had the best production performance, partly, due to improved drilling and completion efficiency. It was also because operators targeted their best acreage to maximize their asset’s potential.

Recycled construction and demolition waste material: a cost–benefit analysis under uncertainty

PurposeConstruction and demolition waste (CDW) continuously causes environmental and social problems. These formidable challenges lead to sustainable issues and are an increasingly urgent issue worldwide. Prior studies have neglected to link the triple bottom line (TBL) to a reliable estimation or empirical model for estimating CDW production performance and lack empirical sensitivity analysis in profit maximization. This study proposes an attribute analysis to build a cost–benefit analysis (CBA) to obtain profit maximization.Design/methodology/approachThis study uses fuzzy set theory to develop a cost and benefit analysis (CBA) model to assess the sensitivity analysis in terms of its performance on addressing the environmental, economic and social aspects. The model is used to weigh the sum of benefits such as financial gain and total costs of actions taken to mitigate the negative impacts.FindingsBased on the sensitivity analysis conducted, the environmental, economic and social mean scales were significantly changed, i.e. increased, and profits increased drastically. The results provide an insight into environmental legislation compliance, environmental investment and environmental impact as the cause attributes for the CDW recycling profit increase. The results prove that sensitivity analysis is viable to infer that a sustainable production performance can achieve more revenue and profit through an adequate selection of attributes regarding the TBL aspects to address the firm's uncertainty problem in multiple criteria analysis.Originality/valueThis study builds a CBA model to maximize profits for recycled CDW material by linking of environmental, economic and societal aspects for recycled CDW assessments. It considers a sustainability structure with criteria based on TBL aspects to assess production performance to realize the Sustainable Development Goals and presents fuzzy set theory and sensitivity analysis to solve the uncertainty problem in the construction industry.

Potency of probiotic on broiler growth performance and economics analysis

The study was undertaken to know the economic analysis in broilers fed probiotic containing Lactobacillus casei and Lactobacillus rhamnosus supplementation in lieu of antibiotic growth promoters (AGP) to feed conversion ratio (FCR) and body weight (BW). The treatments were T0: control, T1: 0.01 g AGP/kg feed, T2: 0.05 g/ kg feed, T3: 0.1 g/ kg feed, T4: 0.025 g probiotic/litre drinking water; T5: 0.05 g probiotic/liter drinking water. Data analysis was carried out using the Analysis of Variance (ANOVA) method, business analysis was held out by XLSTAT then analyzing descriptively. The results indicated that there was a significant difference among the treatments. Probiotic administration of T2, T3, T4 and T5 could increase broiler's body weight and improve feed conversion ratio. The higher production performance and most profitable economic analysis was obtained with the addition of 0.025 g probiotic/litre (T4), which had the best results in a Break Even Point and Return Cost Ratio. It could be concluded that supplementation of 0.025 g probiotic/litre drinking water indicates the improve growth performance and profits in broiler.

A novel model for predicting water cut based on trigonometric function growth curve

Water cut prediction is one of the most important contents of reservoir production performance analysis. Accurate prediction of water cut is crucial to formulate reasonable development plan and adjustment measures. However, the traditional method cannot predict the relationship between water cut and time, and the solution of parameters is also complicated. Based on the similar change rules of water cut and cumulative oil production, six new trigonometric function growth curves are established to predict the water cut of an oilfield. The results show that the new models based on the trigonometric function growth curve are simple and easy to solve. The prediction results of six water cut models are close to each other. Anyone model can be selected in water cut calculation, which saves a lot of calculation time and work. Compared with the Logistic model and Usher model, the prediction error of the new trigonometric function growth curve model is smaller. The model prediction results are in line with the actual development of the oilfield, and have certain practicability and reliability.

Main flow channel index in porous sand reservoirs and its application

Abstract Based on well test interpretation, production performance analysis, overburden permeability and porosity test, gas-water core flooding test and high-pressure mercury injection, a quantitative correlation has been built of in-situ effective permeability with routine permeability and water saturation, and the ranges of Main Flow Channel Index (MFCI) are determined for different permeability levels in porous sand gas reservoirs. A new method to evaluate the in-situ effective permeability of porous sand reservoir and a correlation chart of reserves producing degree and main flow channel index are established. The results reveal that the main flow channel index of porous sand gas reservoirs has close correlation with routine matrix permeability and water saturation. The lower the routine matrix permeability and the higher the water saturation, the lower the MFCI is. If the routine matrix permeability is greater than 5.0×10–3, the MFCI is generally greater than 0.5. When the routine matrix permeability is from 1.0×10–3 to 5.0×10–3, the MFCI is mainly between 0.2 and 0.5. When the routine matrix permeability is less than 1.0×10–3, the MFCI is less than 0.2. The evaluation method of in-situ effective permeability can be used to evaluate newly discovered or not tested porous sand gas reservoirs quickly and identify whether there is tight sand gas. The correlation chart of reserves producing degree and main flow channel index can provide basis for recoverable reserves evaluation and well infilling, and provide technical support for formulation of reasonable technical policy of gas reservoir.

Social Life Cycle Assessment of Product Value Chains Under a Circular Economy Approach: A Case Study in the Plastic Packaging Sector

Environmental and economic impact assessment of products have a long record, while social performance analysis of products have less references in the scientific literature due its particularities and the adaptations needed for the features of the studied subject. In addition, there is a lack of a methodological framework of its application in the analysis of value chains, with the aim of estimating the impacts of technical innovations from the social point of view. This paper describes the theoretical framework and impact assessment approach for the Social Life Cycle Assessment of product value chains under a circular economy approach by applying a scoring system in different subcategories and indicators, considering the plastic packaging sector as a case study. Twelve subcategories have been chosen, because of their relevance to the case study, related to the impacts on the labor conditions, consumers’ well-being, end-of-life of the product, local community conditions, technology and suppliers, among others. The validation of the methodology in the plastic packaging sector is done by considering the main stakeholders involved in the value chain and the particularities of the sector.

Anaerobic co-digestion of waste activated sludge and fish waste: Methane production performance and mechanism analysis

The performances of anaerobic co-digestion (AcD) of waste activated sludge (WAS) and fish waste (FW) were studied through mesophilic biochemical methane potential test. Mixtures of various compositions (0, 1.5, 3, 6 and 10% of FW on the volume basis) were tested as the AcD substrates. Experimental results showed that 1.5% and 3% of FW addition could enhance the cumulative methane production remarkably, increasing from 212.3 mL CH4/g VSfed (100% WAS) to 410.1 mL CH4/g VSfed and 683.8 mL CH4/g VSfed, respectively. However, methane producing was inhibited severely with more than 6% of FW addition, whose cumulative methane production dramatically decreased to approximately 51 mL CH4/g VSfed. Mechanism analysis showed that large amounts of fatty acids accumulation occurred during the AcD with FW addition above 6%, leading to methanogenesis process failure. Microbial community analysis showed that methane producing during AcD was dominated by hydrogenotrophic and methylotrophic methanogenesis pathways led by Methanobacterium and Methanomassiliicoccus.

Comparative analysis of production performance in integrated aquaculture system and single system of production of fish, rice, poultry and pig

As the population of Nigeria continue to increase rapidly, there is corresponding increase in demand for food. In order to secure food security of the growing human population, it is imperative that a suitable agricultural production system that will meet the increasing demand for food be embraced. An important way of increasing agricultural production is through Integrated Aquaculture (IA). IA is known to diversify production thereby ensuring increase productivity and profitability in an ecofriendly manner. This project assesses the productivity of IA as a method of increasing food production. Two integrated combinations, Fish, Rice cum Poultry (FRPo) and Fish, Rice cum Pig (FRPi) were studied for production performance for period of one year. Comparison between productivity of (FRPo), (FRPi) and single system of production of fish, rice, poultry and pig were carried out. Seventeen farms (five fish farms, five poultry farms, five pig production farms and two rice plantations) were selected for the comparison based on their close proximity with the research site so as to reduce spatial error and error due to the influence of climate and weather. Production performance data were monitored daily in the IA systems and in-depth interview was used to collect information on single system of production of rice, fish, poultry and pig. The data collected were subjected to descriptive statistics such as mean, median, and frequency using SPSS version 22. The result of production performance showed that the average weight of fish under FRPo at 12 weeks was 309.9±1.78g; the feed conversion ratio and percentage survivability of the fish under this system were 1.39 and 72.6 respectively; while twenty five kilogram of rice was harvested per 50m². Also, the average weight of fish under FRPi at 12 weeks was 179±1.3g; the feed conversion ratio and percentage survivability of the fish under this system were 1.25 and 50 respectively; twenty eight kilogram of rice was harvested per 50m² under FRPi. The average feed conversion ratio and percentage survivability of fish under the single system of production studied were 1.1 and 78.99 respectively and average weight of rice harvested per 50m² was 11.3kg. Integrated fish farming was more productive and profitable than unitary system of farming as it ensured a spread of financial risk because of its varied and diversified nature in rearing of fish, animals and crops. The research studied also shows that IA offers cost saving strategy of operation in the manner that conserve the ecosystem by converting wastes to resources. IA therefore is a more productive system than the unitary system of production.

The impact of soil and water resource conservation on agricultural production- an analysis of the agricultural production performance in Zhejiang, China

Water and soil resource are fundamental natural resources and one of the determinant factors of the ecological environment. Soil erosion not only affects economic development, but also triggers the occurrence of natural disasters that threaten people's property and lives. Therefore, it is necessary to take various and effective measures and technologies to protect water and soil resources, to promote rapid and stable economic development, and to protect people's livelihood. This paper explores the impact of related policies on soil and water conservation in China in recent years on domestic agricultural development, and analyzes the effects of investment in soil and water conservation and construction on agricultural production in 11 cities in Zhejiang Province, from 2007 to 2016. The empirical results show that the performance of soil and water conservation construction in Zhejiang over the years fell in the range between 0.4 and 0.6, and the overall efficiency value and productivity changes began to decline after the year of 2015. Secondly, mixed cross-sectional data analysis and panel data analysis showed that the performance of soil and water conservation construction had a significantly positive impact on the agricultural outputs (log (Output1)) in each city.

Analysis of growth and production performance was also carried out on paddy in the soil from swampy land, it appeared positive only on the parameters of grain dry weight, plant dry weight (without roots, panicles, and grain).

Simulation Study to Evaluate the Impact of Fracture Parameters on Shale Gas Productivity

The production from shale gas reservoirs has significantly increased due to technological advancements. The shale gas reservoirs are very heterogeneous and the heterogeneity has a significant effect on the quality and productivity of reservoirs. Hence, it is essential to study the behavior of such reservoirs for accurate modelling and performance prediction. To evaluate the impact of fracture parameters on shale gas reservoir productivity using CMG (Computer Modelling Group) stars simulation software was the main objective of this study. In this paper, a comprehensive analysis considering an example shale gas reservoir was conducted for production performance analysis considering uniform and non-uniform fractures configurations. Several simulations were performed by considering the multi-stage hydraulically fractured reservoir. The sensitivities conducted includes the different cases of moderate and severe heterogeneity along with variable fractures half-length, effect of changing fracture spacing, variable fracture conductivities. The simulation results showed that by increasing conductivity of fracture increases the gas production rate significantly. Moreover, cases of reservoir permeability heterogeneity were analyzed which show the significant effect on gas rate and on cumulative gas production. The results of this study can be used to improve the effectiveness in designing and developing of shale gas reservoirs and also to improve the accuracy of analyzing heterogeneous shale gas reservoir performance.

Production Performance Analysis for Multi-Branched Horizontal Wells in Composite Coal Bed Methane Reservoir Considering Stress Sensitivity

Abstract Coal bed methane (CBM) significantly contributes to unconventional energy resources. With the development of the drilling technology, multi-branched horizontal wells (MBHWs) have been put into the exploitation of CBM. In this paper, a semi-analytical mathematical model is introduced to study the production characteristics of MBHWs in the composite CBM reservoir. Stress sensitivity, composite reservoir, and complex seepage mechanisms (desorption, diffusion, and Darcy flow) are taken into consideration. Through Pedrosa transformation, Perturbation transformation, Laplace transformation, Finite cosine transformation, element discretization, superposition principle, and Stehfest numerical inversion, pseudo-pressure dynamic curves and production decline curves are plotted and 13 flow regimes are divided. Then, the sensitivity analysis of related parameters is conducted to study the influences of these parameters based on these two type curves. Model verification and field application are introduced which shows that the model is reliable. The model proposed in this paper and relevant results analysis can provide some significant guidance for a better understanding of the production behavior of MBHWs in the composite CBM reservoir.

MARKETING OF INVESTMENT OPPORTUNITIES OF UKRAINIAN DIVERSIFIED ENTERPRISES

Introduction. Marketing of investment opportunities is one of the fundamentals of the enterprise, obtaining financing and a tool to respond to changes in the market of goods, services and finance. In addition, the study allows to identify existing trends in the development of diversified enterprises in production, organization and financial areas. There is also feedback, because the analysis of production and financial performance of the enterprise will allow you to more effectively plan and adjust the policy to attract investment for future periods. The purpose of the study is to substantiate the effectiveness of the use of financial indicators of a diversified enterprise from the standpoint of their importance as a factor in attracting investors within the organization of marketing investment policy. Results. In the course of the work the key indicators of the financial activity of the diversified company were analyzed. A comparative analysis of similar financial indicators of several years was conducted to identify possible trends in the financial development of the enterprise at different time intervals. The analysis also revealed the relationships between the analyzed indicators, which were used to predict the direction of possible changes in these financial indicators for several future years. In this situation, the main thing is the fact that the decline to such indicators was planned and clearly predicted, as well as the growth of the corresponding indicator in the period 2016-2017. It should be noted that the growth and decline of this indicator during the study period occurred at the same rate. Predicting the future dynamics of this indicator, we can confidently say about its further growth at a similar pace. Conclusions. The situation with the development of the analyzed indicators during this period cannot be called standard. It is worth talking about the negative phenomena in the whole sphere of activity of this enterprise. Despite this, only such events can show all the importance of the enterprise, the balance and security of its systems. The analysis showed that the company has steadily and predictably overcome these negative phenomena and reached new significant volumes of production and development in general. This fact is one of the most important in assessing competitiveness, namely as the ability to respond quickly and efficiently to changes in the economic macroenvironment of the industry. Keywords: diversification, investment marketing, enterprises, financial indicators

A Standard Method for Performance Detection of Fluorescence Imaging System

Fluorescence imaging now becomes an intraoperative navigation technique that gaining popularity in surgery and clinical research. However, at present, there is no mature and reliable method or other related guidance documents for the detection of fluorescence imaging performance. The performance analysis and quality supervision of products on the market could not be performed, which affects their clinical use and image quality. In this paper, a standard method of fluorescence imaging performance testing for fluorescence imaging system is proposed. Several kinds of fluorescence imaging performance parameters affecting fluorescence images are defined strictly. We also recommend scientific and feasible methods for their detections and analyses, which are verified by practical examples. This paper aims to provide a feasible reference standard for fluorescence performance evaluation.

Study Assesses Incentives, Development Strategies for Peruvian Mature Heavy Oil

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 196217, “Assessment of Government Incentives and Development Strategies To Revitalize Mature Heavy-Oil Fields in the Peruvian Jungle,” by Nosser A. Jurado, SPE, National Bank Financial, and Victor A. Huerta, SPE, Universidad Nacional de IngenerÍ​​​​​​​a, prepared for the 2019 SPE Annual Technical Conference and Exhibition, Calgary, 30 September–2 October. The paper has not been peer reviewed. Mature heavy-oil fields in the northern Peruvian jungle have produced oil for more than 40 years under primary recovery mechanisms (cold methods). The complete paper explores technical and economic development options to produce heavy-oil resources at commercial rates and showcases three optimization scenarios of higher recovery efficiency aimed at increasing net present value at the basin level. Introduction The constant decline of medium- and light-oil production in most Peruvian fields in recent years, along with the increase in domestic demand, indicates that innovative redevelopment strategies should be implemented for recent large heavy-oil discoveries in the Marañon Basin. The Norperuano pipeline in its current condition and egress capacity allows exploitation of proved developed producing volumes of Blocks 64, 192, 8, and 95 but constrains the commerciality and development possibilities for Block 67 (Piraña, Dorado, and Paiche fields) and Block 64 (Situche field), which jointly could pro-duce up to 70,000 B/D between 2027 and 2029. The main issue is the present constraint for transportation and blending of heavy oil and diluents. Therefore, an infrastructure revamp is necessary. The authors believe that capital expenditure (CAPEX) to carry out these improvements and expansions is necessary and must be addressed between the operators in the area and the Peruvian government while considering all social and current environmental issues. Analysis of Production Performance and Recovery Most Peruvian heavy-oil fields have been discovered in the Marañon Basin. Production history indicates a strong water-drive mechanism by which oil production declines as water rate increases, while reservoir pressure is sustained with a less than 20% pressure decrease. Generally speaking, Marañon wells have been drilled following slant trajectories and are only completed with slotted liners without a selective completion. Consequently, no method exists to isolate water zones or encroachment, and oil productivity and relative permeability to oil decrease rapidly as water cut increases. Horizontal wells have been proposed for the Bretaña heavy-oil field in Block 95. This field is similar to the Jibaro and Jibarito fields in Block 192, with completions featuring autonomous inflow-control devices (AICDs) to delay water breakthrough while improving production performance and increasing oil recovery. Another alternative suggested to increase recovery factor and prevent water breakthrough is dual completion with electrical submersible pumps (ESPs). This completion type has been envisioned for Block 192. On a well-by-well basis, increasing the recovery factor by implementing new technologies is possible. On a transportation-and-gathering basis, however, issues remain in the basin. A production deferment of at least 7% has been the result of several factors, including a lack of appropriate well-service programs to replace ESPs and clean boreholes, inadequate infrastructure, deteriorating roads accessing the fields, the lack of a supply-change-management program, and a lack of appropriate management of social and environmental issues. CAPEX allocations to the Norperuano pipeline would minimize this problem at the basin level and might solve delay issues at the field level for all blocks.

Performance Analysis of Colored PLA Products with a Fused Filament Fabrication Process.

The objective of the present work is to study the influence of color additives used for the polylactic acid (PLA) filament on the final quality of fused filament fabrication (FFF) parts. The main processing parameters of FFF parts were evaluated, identifying the significant correlations between PLA properties and part performance, using a commercial FFF machine. The quality of the products was evaluated in terms of thermo-mechanical properties such as mechanical strength, principal material temperatures, and viscosity. These last properties were characterized using differential scanning calorimetry (DSC) for the thermal measurements and a rotational rheometry (RHEO) for viscosity measurements. Cylindrical specimens were then produced for the compression test. The experimental activity and related testing of products are fully described, pointing out a significant difference in performance between parts made of different colored filaments.

Application of binary compound water control technology in the development of horizontal wells in offshore oil fields

Offshore A oil field is a typical bottom water reservoir with thin thickness of oil layer and large thickness ratio of water layer and oil layer. Due to its strong bottom water energy, serious non-homogenous and the impact of the bottom ridge, most of the horizontal well production segment is seriously water out.Based on interaction relationship between horizontal segment trajectory and oil and-water interface, the distribution and contrast of permeability along horizontal segment and the comprehensive analysis of production performance, this paper combines the characteristics of the residual oil distribution of typical wells and the mechanism of dual compound oil addition, and from the perspective of combining theory with the field creatively put forward the dual composite water control mode of first injecting gel segment plug and then injecting foam. then completed the design of dual compound water control mode and dosage of the typical well. After processing water control measures, the production data shows that the water content decreased significantly after opening the well, from 95.1% before water control to 80%, which was 15% lower. Also the oil production rate has a significant increase from 2.3t/d before water control to maximum to 9t/d after implementing control measures and cumulative oil increase is 550t with effective period of 135 days. The effect of oil and precipitation is obvious.
