A new formulation to easy simulation and optimization of gas and oil production systems is presented in this work. The problem of interest corresponds to the typical daily gas and oil production calculation, i.e. a one-day time period planning. The simulation problem considers determination of oil and gas production for the current topology. The optimization problem is established by considerin...

This paper presents an oil price cartel model. The aggregate reaction functions for non-cartel producers and for substitute suppliers are included. The former group acts as a price-taker, while the latter expects oil prices in production of its non-oil energy resources. This expectation about prices affects a cartel’s oil demand and, thus, gives intertemporal price elasticities It turns out tha...

abstract i n this paper, we investigate the existence and the nature of real exchange rate misalignment in organization of the petroleum exporting countries (opec). to do this we estimated a cross country basic real exchange rate determination model for 1990-2012 and extracted historic trend of misalignment. the results imply that all opec countries have had misalignment -of different kinds tho...

A number of oil market experts argue that OPEC members substantially overreport their reserves. The potential damage for the world economy calls for an analysis of the motives and the preconditions for successful misreporting of natural resource reserves. Based on a signalling game within an international trade model, this article develops a framework for such an analysis. Exporting countries w...

We consider whether a newspaper article count index related to the organization of petroleum exporting countries (OPEC), which rises in response important OPEC meetings and events connected with production levels, contains predictive power for foreign exchange rates G10 countries. The applied Bayesian inference methodology synthesizes wide array established approaches modelling rate dynamics, w...

Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a eld with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil wells of the eld such that the total production of oil from the eld is maximized. This paper describes a non-linear optimization problem with constra...
