The Evolution of Giant Oil Field Production Behavior
Springer Science and Business Media LLC - Tập 18 - Trang 39-56 - 2009
Mikael Höök, Bengt Söderbergh, Kristofer Jakobsson, Kjell Aleklett
The giant oil fields of the world are only a small fraction of the total number of fields, but their importance is huge. Over 50% of the world’s oil production came from giants by 2005 and more than half of the world’s ultimate reserves are found in giants. Based on this, it is reasonable to assume that the future development of the giant oil fields will have a significant impact on the world oil ...... hiện toàn bộ
Storage Potential of Multi-State Fluids in Different Lithotypes of Lignite: An In Situ Water-Gas-Bearing Analysis Based on Nuclear Magnetic Resonance
Springer Science and Business Media LLC - Tập 32 - Trang 1199-1214 - 2023
Fudong Xin, Hao Xu, Dazhen Tang, Can Cao
The reservoir properties and gas-bearing characteristics of different lithotypes of lignite are different, resulting in complex migration and accumulation laws of methane in lignite. Following systematic collections of samples of different lithotypes from the Erlian Basin, occurrence modes and storage potential of methane in lignite were explored through a series of isothermal adsorption experimen...... hiện toàn bộ
Application of Land Magnetic and Geoelectrical Techniques for Delineating Groundwater Aquifer: Case Study in East Oweinat, Western Desert, Egypt
Springer Science and Business Media LLC - Tập 30 - Trang 4219-4233 - 2021
Sultan Awad Sultan Araffa, Sayed Bedair
Two geophysical tools were used to delineate the configuration of the Nubian sandstone aquifer in the study area. Three hundred magnetic points were measured and analyzed to evaluate the subsurface structural setting and to trace the basement relief, which control the aquifer’s geometry. The magnetic interpretations refer to dominant faults that strike in various directions, namely N–S, NE–SW, and...... hiện toàn bộ
Dynamics Behind Cycles and Co-movements in Metal Prices: An Empirical Study Using Band-Pass Filters
Springer Science and Business Media LLC - Tập 29 - Trang 1487-1519 - 2019
Matias Marañon, Mustafa Kumral
After living one of the most intense metal price cycles, several ongoing macroeconomic phenomena with the potential of structurally redefining the long-run supply and demand for metals, and raising divergency regarding where the metal prices are trending, it is suitable to evaluate the dynamics in the metal prices, especially focus on the long cyclical components. This article studies in detail th...... hiện toàn bộ

Computational Intelligence Model for Estimating Intensity of Blast-Induced Ground Vibration in a Mine Based on Imperialist Competitive and Extreme Gradient Boosting Algorithms
Springer Science and Business Media LLC - Tập 29 - Trang 751-769 - 2019
Ziwei Ding, Hoang Nguyen, Xuan-Nam Bui, Jian Zhou, Hossein Moayedi
In this paper, we developed a novel hybrid model ICA–XGBoost for estimating blast-produced ground vibration in a mine based on extreme gradient boosting (XGBoost) and imperialist competitive algorithm (ICA). For comparison, we used another hybrid model combining particle swarm optimization and XGBoost [i.e., particle swarm optimization (PSO)–XGBoost] as well as other models, namely classical XGBoo...... hiện toàn bộ
Evolution of County Socio–Ecological Systems in Nature Reserves in Western China Over the Past 30 Years
Springer Science and Business Media LLC - Tập 32 - Trang 1809-1822 - 2023
Qinhua Wang, Le Chen, Penglong Wang, Bao Wang, Taibao Yang
The evolution process of socio–ecological systems from 1990 to 2020 in the Tianzhu Tibetan Autonomous County, located in the National Key Ecological Function Area of western China, was analyzed quantitatively based on resilience theory and methodology combined with catastrophe theory and adaptive cycle theory, through field investigation, questionnaires and interviews, social data collection and r...... hiện toàn bộ
Evaluation of Source Rock Potentiality and Prediction of Total Organic Carbon Using Well Log Data and Integrated Methods of Multivariate Analysis, Machine Learning, and Geochemical Analysis
Springer Science and Business Media LLC - Tập 31 - Trang 619-641 - 2022
Edwin E. Nyakilla, Selemani N. Silingi, Chuanbo Shen, Gu Jun, Alvin K. Mulashani, Patrick E. Chibura
In this study, integrated approaches based on multivariate analysis (MVA), machine learning (ML), and geochemical analysis are proposed to investigate the potential of hydrocarbon reserves and total organic carbon (TOC) prediction. These approaches employed the MVA technique as a future selection method in source rock evaluation. We used geochemical data from 30 core samples taken equally from wel...... hiện toàn bộ
Analysis of Spatial–Temporal Evolution of Mining-Induced Fracture Field: A Case Study Using Image Processing in the Shaqu Coal Mine, China
Springer Science and Business Media LLC - Tập 29 Số 3 - Trang 1601-1615 - 2020
Zhiheng Cheng, Biao Liu, Quanle Zou, Xin Wang, Jianguo Feng, Zhenyu Zhao, Fulong Sun
A New Semi-greedy Approach to Enhance Drillhole Planning
Springer Science and Business Media LLC - - 2020
Raphaël Dutaut, Denis Marcotte
In advanced exploration projects or operating mines, the process of allocating capital for infill drilling programs is a significant and recurrent challenge. Within a large company, the different mine sites and projects compete for the available funds for drilling. To maximize a project’s value to its company, a drillhole location optimizer can be used as an objective tool to compare drilling camp...... hiện toàn bộ
