Multi-component Seismic Data Gas producers across the Gulf of Mexico are targeting deeper and deeper drilling objectives. Most operators in the Gulf consider 30,000ft to be the deepest target depth that will be drilled for the next few years. To image geology at those depths, seismic reflection data must be acquired with offsets of at least 30,000ft. TECHNOLOGY DEVELOPMENTS IN NATURAL GAS EXPLO...

In this article, the U.S. and southern Canadian natural gas supply market is considered. An important model for oil and natural gas supply is the Hubbert curve. Not all regions of the world are producing oil or natural gas following a Hubbert curve, even when price and market conditions are accounted for. One reason is that institutions are affecting supply. We investigate the possible effects ...

The system of gas-dynamic equations, corresponding to the first order of approximation in the successive approximations method of solution of kinetic Boltzmann equation for multi-component mixture of gases, is derived. Interpretation of turbulent flows of gases is proposed within frames of multi-component gas dynamics, as stratified on components flows of gases. PACS numbers: 02.30.Mv, 05.20.Dd...

in this paper, a model based on gmdh type neural network, is used to predict gas price in the spot market while using oil spot market price, gas spot market price, gas future market price, oil future market price and average temperature of the weather. the results suggest that gmdh neural network model, according to the root mean squared error (rmse) and direction statistics (dstat) statistics ...

Genetic algorithms (GAs) are a class of stochastic optimization methods inspired by the principles of natural evolution. Adaptation of strategy parameters and genetic operators has become an important and promising research area in GAs. Many researchers are applying adaptive techniques to guide the search of GAs toward optimum solutions. Mutation is a key component of GAs. It is a variation ope...

In our previous work [Sens. Actuator B: Chem. 203 1-8 (2014)], a ultrasonic sensor has been proposed to detect gas compositions by the acoustic spectral peak location. However, the effective relaxation area constructed by existing theoretical model cannot match the detection method when there are more than one strong relaxational components in gas mixture. A method that calculates the relaxatio...
