Forecasting the production of Distillate Fuel Oil Refinery and Propane Blender net production by using Time Series Algorithms [PDF]

open access: yesarXiv, 2022
Oil production forecasting is an important step in controlling the cost-effect and monitoring the functioning of petroleum reservoirs. As a result, oil production forecasting makes it easier for reservoir engineers to develop feasible projects, which helps to avoid risky investments and achieve long-term growth.

Influence of petroleum and gas trade on EU economies from the reduced Google matrix analysis of UN COMTRADE data [PDF]

open access: yesEur. Phys. J. B (2019) 92: 171, 2019
Using the United Nations COMTRADE database we apply the reduced Google matrix (REGOMAX) algorithm to analyze the multiproduct world trade in years 2004-2016. Our approach allows to determine the trade balance sensitivity of a group of countries to a specific product price increase from a specific exporting country taking into account all direct and ...

A Critical Discourse Analysis of Newspaper Texts on the Science of Crude Oil Refining in Nigeria

open access: yesJournalism and Media, 2022
As a country with a remarkable crude oil deposit, it is a dark irony that Nigeria depends on importation for its petroleum product needs. The devastating impact on Nigeria’s economy of this dependence continues to provoke polemics. Recently, the polemics

Real-Time Event Detection with Random Forests and Temporal Convolutional Networks for More Sustainable Petroleum Industry [PDF]

open access: yesarXiv, 2023
The petroleum industry is crucial for modern society, but the production process is complex and risky. During the production, accidents or failures, resulting from undesired production events, can cause severe environmental and economic damage. Previous studies have investigated machine learning (ML) methods for undesired event detection.
