Forecasting Crude Oil Prices Using Reservoir Computing Models [PDF]
arXiv, 2023 Accurate crude oil price prediction is crucial for financial decision-making. We propose a novel reservoir computing model for forecasting crude oil prices. It outperforms popular deep learning methods in most scenarios, as demonstrated through rigorous evaluation using daily closing price data from major stock market indices.

A hidden Markov model for statistical arbitrage in international crude oil futures markets [PDF]
arXiv, 2023 In this work, we study statistical arbitrage strategies in international crude oil futures markets. We analyse strategies that extend classical pairs trading strategies, considering the two benchmark crude oil futures (Brent and WTI) together with the newly introduced Shanghai crude oil futures.

The short-term effect of COVID-19 pandemic on China's crude oil futures market: A study based on multifractal analysis [PDF]
, 2022 The ongoing COVID-19 shocked financial markets globally, including China's crude oil future market, which is the third most traded crude oil futures after WTI and Brent. As China's first crude oil futures accessible to foreign investors, the Shanghai crude oil futures (SC) have attracted significant interest since launch at the Shanghai International ...

Influence of Sequential Changes in the Crude Oil-Water Interfacial Tension on Spontaneous Imbibition in Oil-Wet Sandstone [PDF]
, 2021 Crude oil-water interfacial tension in petroleum reservoir is reduced or increased due to surfactant injection or surfactant retention, respectively. Changes in the interfacial tension crucially attribute to a governing capillary pressure and hence an oil displacement in spontaneous imbibition process.
