oil-exporting economies largely dependent on oil revenues and oil income fluctuation are one of the most important factors that influence sectors of the economy specially the stock market. this paper investigate the relationship between oil markets and stock return volatility and transmission in a selection of opec countries, using a multivariate garch models (full-vech) over the period may 201...

This article examines the real convergence hypothesis in OPEC countries (Algeria, Angola, Ecuador, Gabon, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates and Venezuela) using time series techniques and allowing for structural breaks. The main results show lack of support for income convergence in OPEC countries. We only find evidence of catch-up with the...

This paper studies how changes in oil supply expectations affect the price and macroeconomy. Using a novel identification design, exploiting institutional features of OPEC high-frequency data, I identify an news shock. These shocks have statistically economically significant effects. Negative leads to immediate increase prices, gradual fall production, inventories. has consequences for US econo...

the organization of the petroleum exporting countries (opec) has a key role in making universal political and economic decisions regarding petroleum. therefore, it seems highly important to assess the opec member’s degree of concentration and its monopoly.  this research, aims to assess and classify the concentration of petroleum export in the opec countries during the 1997-2011 period by the h...

In the global economy, crude oil is among the most important strategic goods that affects the performance of local and international markets. Prediction of the oil price has always been an important challenging topic in the global economy and producers and consumers have constantly been trying to improve their roll in the oil price changes and for many years OPEC has been one of the key players...

Oil sector is the most effective sector in these countries. Oil is the most important product that world industries use as the cheapest energy. The price of oil depends on the world’s supply and demand and many economic, political and geographical variables. This is the reason why the price of oil has fluctuations. The fluctuations in oil price lead to fluctuate in the oil revenues of the membe...

This paper proposes an optimization strategy which is based on neural networks and genetic algorithms to calculate the optimal values of gas injection rate and oil rate for oil production system. Two cases are analyzed: a) A single well production system and b) A production system composed by two gaslifted wells. For both cases an objective function is maximized to reduce production cost. The p...

In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...
