NOVEL METHODOLOGY FOR AUTOMATION OF BAD WELL LOG DATA IDENTIFICATION AND REPAIR
Authors:   PetroRes Consulting, Banas Ryan , McDonald Andrew ,   Lloyd’s Register, Perkins Tegwyn ,   Lloyd’s Register
Published: August 2021

Subsurface analysis-driven field development requires quality data as input into analysis, modelling, and planning. In the case of many conventional reservoirs, pay intervals are often well consolidated and maintain integrity under drilling and geological stresses providing an ideal logging environment. Consequently, editing well logs is often overlooked or dismissed entirely. Petrophysical analysis however is not always constrained to conventional pay intervals. When developing an unconventional reservoir, pay sections may be comprised of shales. The requirement for edited and quality checked logs becomes crucial to accurately assess storage volumes in place. Edited curves can also serve as inputs to engineering studies, geological and geophysical models, reservoir evaluation, and many machine learning models employed today. As an example, hydraulic fracturing model inputs may span over adjacent shale beds around a target reservoir, which are frequently washed out. These washed out sections may seriously impact logging measurements of interest, such as bulk density and acoustic compressional slowness, which are used to generate elastic properties and compute geomechanical curves. Two classifications of machine learning algorithms for identifying outliers and poor-quality data due to bad hole conditions are discussed: supervised and unsupervised learning. The first allows the expert to train a model from existing and categorized data, whereas unsupervised learning algorithms learn from a collection of unlabeled data. Each classification type has distinct advantages and disadvantages. Identifying outliers and conditioning well logs prior to a petrophysical analysis or machine learning model can be a time-consuming and laborious process, especially when large multi-well datasets are considered. In this study, a new supervised learning algorithm is presented that utilizes multiple-linear regression analysis to repair well log data in an iterative and automated routine. This technique allows outliers to be identified and repaired whilst improving the efficiency of the log data editing process without compromising accuracy. The algorithm uses sophisticated logic and curve predictions derived via multiple linear regression in order to systematically repair various well logs. A clear improvement in efficiency is observed when the algorithm is compared to other currently used methods. These include manual processing by a petrophysicist and unsupervised outlier detection methods. The algorithm can also be leveraged over multiple wells to produce more generalized predictions. Through a platform created to quickly identify and repair invalid log data, the results are controlled through input and supervision by the user. This methodology is not a direct replacement of an expert interpreter, but complementary by allowing the petrophysicist to leverage computing power, improve consistency, reduce error and improve turnaround time.

Published: August 2021

The study aimed to determine the genotypic distribution of the c.328 G>A (rs110652478) polymorphism in the bovine fatty acid-binding protein 4 (FABP4) gene and to determine its effect on slaughter weight in Aberdeen Angus and Hereford bulls imported into Turkey. A total of randomly selected 95 bulls were used in this study. Bulls were housed for fattening in semi-open pens for approximately nine months with the same management procedures. Genotyping of the FABP4 c.328 G>A (rs110652478) polymorphism, located in exon 3, was performed by the PCR-RFLP method. Allele and genotype frequencies were calculated by the standard procedures and the Hardy-Weinberg equilibrium was tested by comparing expected and observed genotype frequencies using chi-square and Fisher’s exact tests. Indices of genetic diversity were calculated based on the allelic frequencies. The least-squares method as applied in a GLM procedure was used to test the association between FABP4 c.328 G>A and phenotypic traits including slaughter weight, hot and cold carcass weight, chilling loss, dressing percentage, and carcass pH. Results revealed that the most frequent genotype was GG (49.18% and 52.94% for Angus and Herefords, respectively) and the minor allele frequency (A allele) was 0.32 in the total population. The genotype distribution was in agreement with Hardy Weinberg equilibrium (P>0.05). The moderately low levels of genetic variability observed in this study may be caused as a result of eventual inbreeding. PIC levels suggest that FABP4 c.328 G>A can be a mildly informative genetic marker for the tested population. Association analysis indicated that the effect of the FABP4 on slaughter weight was statistically significant (PA may provide valuable, but limited, information on imported beef cattle raised in Turkey conditions.

The aim of the article is to identify the characteristics and creative potential of customization in modern design activities, through which the needs for individualization of clothing at the request of consumers are widely realized. The methodological basis of the study is an integrated approach. The method of analysis and synthesis allowed the consideration of customized production as the interaction of producer and consumer, which determines the demand and competitiveness of the design product, its artistic and aesthetic value. Methods of visual-analytical and functional analysis of customized design objects provided an opportunity to establish the potential and prospects of mass customization, to justify it in terms of individualization of things as a specific consumer choice, as well as the principle of designing design objects in the learning process. It is established that, according to most scientists, customization is, first of all, individualization of the producer's relationship with the consumer. Prerequisites for its active use in the fashion industry, in particular, in design activities, are long overdue. It was found that by satisfying individual customer requests, using flexible production systems, etc., mass customization allows companies in the fashion industry to get rid of excess stocks of finished products that become obsolete too quickly, and makes it possible to make products more attractive. It is shown that the concept of "smart (savings) consumption", for which the principles of customization are extremely promising, can be successfully implemented in the process of providing educational services. The article highlights the theoretical aspects of the essence of customization as a "mass individualization" of design products. The existing principles of clothing customization are analyzed. Possibilities and types of customization in the activity of modern designers against the background of real market conditions are characterized. The potential of customizing in design in general and in the educational process of training fashion designers in particular is shown. The obtained results provide an opportunity to systematize the types, principles and techniques of customization as an experience of practical implementation of the concepts of "smart consumption", individualization and personification in clothing design.

K-means a fairly simple and commonly used cluster of clusters to partition datasets into multiple clusters. Distance calculations are used to find similar data objects that lead to developing powerful algorithms for datamining such as classification and grouping. Some studies apply k-means algorithms using distance calculations such as Euclidean, Manhattan and Minkowski. The study used datasets from gynecological patients with a total of 401 patients examined and as many as 205 patients detected cervical cancer, while 196 other patients did not have cervical cancer. The results were shown with the help of confusion matrix and ROC curve, accuracy value obtained by 79.30% with ROC 79.17% on K-Means Euclidean Metric while K-Means Manhattan Metric by 67.83% with ROC 65.94%. Thus it can be concluded that the Euclidean method is the best method to be applied in the K-Means Clustering algorithm on cervical cancer datasets.

Lack of water can cause serious health problems.  In reality, some people do not know the amount of water they must drink daily.  It's hard to find out the daily water intake needs because it is affected by a lot of things and it will be better to involve a nutritionist or health expert to get the best amount, which may require extra cost. To overcome these problems, it is necessary to have a system that is incorporated in an integrated system with the ability to calculate the ideal level of water needs for the body according to factors that affect the level of water needs and able to remind users to keep their daily needs. IoT-based smart water dispensers that can be integrated with android applications and cloud servers into a single system can be used to help solve these problems. The system has a knowledge base obtained from professionals to determine user water consumption. The system calculates the water consumption using the GPPAQ questioner and Estimated Energy Requirement (EER) formula. The base knowledge is implemented on Android applications, and this application can track the amount of water that has been consumed by the user. The test results show that the system can calculate the amount of water demand based on some factors such as the level of physical activity, age, and body weight. The water dispenser system has an accuracy of recording the amount of air released by 92.6%, so there is a difference in the calculation in the Android application to the amount of air that the user takes from the water dispenser

Then an analysis of the results of decision support for obtaining a company official residence was carried out using the Analytical Hierarchy Process (Ahp) and Technique For Order Preference By Similarity To Ideal Solution (Topsis). The final results of the AHP method trial evaluation result in accurate data where there are 5 employees who are truly in the very feasible category to get an official residence. Whereas in the AHP method there are differences in the results found, where it is found that the number of employees is 1 person who should be in the feasible category but belongs to the very feasible category, so that the number generated from the TOPSIS method is 6 people. With these 2 methods, it can produce an accuracy value of around 60% by entering all the specified criteria.
