A high log demand that often exceeds its supply capability should be overcome by using appropriate logging  tools. Numerous  kinds and types of logging  tools require  a well planning in their utilization. Number of tools which are greater or fewer than what is actually needed can be disadvantageous  for a company. In relevant to these aspects, a study was carried out at a timber estate in Central Kalimantan  in 2007. The aim of the study was to find out an efficient number  of tools used for logging  in a timber  estate. The analysis was based on t

Summary This paper describes the hardware and operation of a new generation of nuclear magnetic resonance (NMR) logging tools. In the past, NMR required the logging engineer to consider the T1 relaxation times of the reservoir fluids likely to be encountered. Actual, or simply assumed, long T1's translated into slow logging speeds. The new tool generation overcomes this limitation. The key feature is that nine sensitive volumes are polarized in parallel and are read out in rapid sequence. A new sonde design speeds up the polarization process by a factor of 2. Each volume contributes equally to

The prediction of dispersion curves is an essential part of understanding borehole acoustic modes. Traditional dispersion curve calculation requires finding zeros of the determinant of the characteristic matrix of a borehole system. This approach is subject to interpretational ambiguity because the determinant can be scaled arbitrarily. We have developed an alternative approach based on the reciprocal condition number (RCN) of the characteristic matrix. The RCN quantifies the singularity of a matrix on a fixed scale between zero and unity; thus, it represents wave modal strengths. We find that

The invasion effect can be so strong that the conductivity derived using the 1D model can be substantially affected. We have developed an efficient forward-modeling app

Cognitive load theory has been gaining increasing levels of importance within usability evaluations for mobile applications and the user interface. The PACMAD model has proven that cognitive workload (CL) can be seen as being a primary usability evaluation attribute in relation to mobile applications. Once the tasks that have been assigned to users within the environment of the mobile application have been performed by the evaluator, he/she subjectively measures the CL. Typically, s

Geophysical research methods are actively used in the exploration of hydrocarbon deposits, the peculiarity of which is the remoteness of the studied objects from the observer's point. The main purpose of geophysical research is to obtain, transmit, and process information about the topography, soil composition, and quantity and location of groundwater. Such studies are carried out at the end of drilling the well of the exact cut interval using devices lowered into the well on a special geophysical cable. Currently, equipment is being actively developed that helps geophysicists determine the pa

Abstract The research is aimed at expanding the applicability of the logging tool with toroidal coils from vertical to highly deviated wells. Its electromagnetic signals are computed with a three-dimensional finite-difference simulation algorithm on the computing resources of the Siberian Supercomputer Center of SB RAS, which is accompanied by a multi-aspect numerical analysis of the signals. We consider a wide range of geoelectric models with various resistivity contrasts: those of oil-, gas- and water-saturated reservoirs having a different number of horizontal boundaries and varying thickne

Abstract With the increasing complexity of oil and gas reservoirs, the identification of reservoirs and fluid properties has become more and more difficult, which brings more challenges to hydrocarbon discovery and interpretation, economic capacity assessment, and development program formulation, and at the same time, the process of decision-making in efficient exploration and development is particularly important, which puts higher requirements on the real-time and accuracy of interpretation while drilling. At present, the recording and analysis tools are constantly enriched, showing obvious

Bio-logging is a common method to collect ecological data on wild animals, but might also induce stress, reduce body condition, and alter behavior. Eurasian beavers (Castor fiber) are a semi-aquatic and nocturnal species that are challenging to observe in the wild. Bio-loggers are hence useful tools to study their behaviour and movements, but this raises concerns of potential negative impacts of tagging. To investigate the potential negative impacts of glue-on tags, we compared body weight change for tagged and untagged Eurasian beavers. We hypothesized that tagged beavers would gain less body

The COVID-19 outbreak has forced businesses to shift to an unprecedented “work from home” company environment. While this provides advantages for employees and businesses, it also leads to a multitude of shortcomings, most prevalent of which is the emergence of additional security risks. Previous to the outbreak, company computer networks were mainly confined within its facilities. The pandemic has now caused this network to “spread thin,” as the majority of employees work remotely. This has opened up a variety of new vulnerabilities, as workers’ cyber protection is not the same at home as it

Deforestation is currently among the most critical ecological issues, which need to be addressed urgently. Hence, identification of effective environmental monitoring methods is of top priority, especially in locations where no precise ground-based data are available. Constant development of remote sensing technology provides an increasing number of tools needed for that purpose, based on extraction of information about Earth’s surface. One of the most advanced Earth Observation (EO) programs is Copernicus, established by European Space Agency (ESA). It incorporates a constellation of Sentinel

The goal of this study was to develop a GIS-based Decision Support Model for selecting the best timber harvesting systems on steep terrain. The model combines multiple layers, each representing an important factor in mechanized logging. These layers are used to create a final map that functions as a spatially explicit Decision Support Model that helps decide which machines are best suited for different forest areas. A key idea of this study is to consider not only operational criteria (slope, ruggedness, wetness, and road accessibility), but also a fundamental silvicultural aspect, i.e., the a

Summary A review of the use of measurement while drilling (MWD), logging while drilling (LWD), and directional drilling (DD) tools mobilized to offshore drilling units in the North Sea highlighted an opportunity to lower operational cost for the operator and reduce capital used for the oilfield services company. An objective was set to develop a risk-based probability model that would assess the positive and negative financial impacts of reducing, or perhaps entirely removing, backup tools in this historically risk-averse basin. The scope of the initial analysis was a drilling campaign on a si

The total area of the forest fund of Ukraine is 10400000 hectares, of which 9600000 hectares are covered with forest vegetation. In total, 15.9 % of the country's area is covered by forests. This figure is growing: in 50 years the area of forests increased by 21 %, almost three times increased stock of wood – it is estimated within 2102 million cubic meters. But this is not enough. Today there are a number of problems connected with forestry, for example: mass destruction of forests, lack of forest development strategy, low level of forest resources use, lack of reliable information about the

AbstractThe Golden Langur Conservation Project in Assam, India, was initiated to involve local NGOs and communities in protecting the Endangered golden langur Trachypithecus geei and its habitat on a regional basis within a complex political situation. Since langurs are leaf eaters they are dependent on forests. The Project area, once dominated by militant action and ethnic violence, is in a densely populated area and formerly suffered much illegal deforestation and accompanying reduction in the golden langur population. The Project began with two NGOs and evolved into the formation of a forum
