If one tries to correlate the core and log data for the entire reservoir, the correlation coefficient is usually not very high. For example, consider the dataset in Fig. The correlation coefficient between core permeability at net overburden pressure is only 0.

However, if the cores containing visible natural or coring induced fractures are removed and only cores from clean, fluvial-deltaic channel sands are correlated, the correlation coefficient between permeability and porosity increases to 0.

In their paper, Amaefule et al. Using these two parameter groups, Gas prices thesis developed a scheme to correlate formation permeability with effective porosity as a function of the FZI. For natural gas, the distribution is log-normal.

As the value of reservoir permeability decreases, the value of OGIP increases exponentially. There is obviously a difference between OGIP and reserves.

Why Ethanol Free Gas is More Popular than E85

The OGIP represents all the gas in the rocks that comprise the reservoir layers. Reserves represent the amount of gas that can be produced economically. The value of reserves is a function of gas prices, costs, and the level of technology used to develop the resource.

In high permeability reservoirs, using such cutoffs may be appropriate, especially if the reservoir produces water above a certain water saturation cutoff and the OGIP estimates are not very sensitive to the cutoff values chosen. However, in most tight gas reservoirs, only dry gas and small volumes of water that condense in the wellbore are produced.

Very seldom are large volumes of water produced in tight gas reservoirs. The first step is to compute the value of porosity after making clay correlations with Eqs. The porosity can then be used to compute the water saturation, normally using the dual-water saturation model.

In the tight gas sands research project sponsored by the Gas Research Inst.

Tight gas reservoirs generate many difficult problems for geologists, engineers, and managers. Cumulative gas recovery (thus income) per well is limited because of low gas flow rates and low recovery efficiencies when compared to most high permeability wells.

To illustrate this concept, four data sets obtained from public records are presented for discussion. The data in Fig. These reservoirs are in different basins but, remarkably, have very similar log-normal permeability distributions. More information concerning the permeability distribution for these four data sets is presented in Table 1.

The median permeability for all four formations ranges from 0. Table 1—Arithmetic Means and Medians for Field Cases When the permeability is distributed log-normally, the median value rather than the arithmetic mean should be used to determine the average value of permeability for the formation.

There is a positive correlation between porosity and permeability, as illustrated in Fig. As porosity increases, the permeability increases. There is a negative correlation between net gas pay and permeability, as illustrated in Fig.Login to access the Oil & Gas Journal Subscriber Premium features.

Kinder Morgan (NYSE:KMI) is well-positioned to benefit from the long-term natural gas consumption megatrend. Topic Sentence and Thesis Statement: The Keystones of Organized Writing. You are here A thesis is not a title however, the Ph.D. pumping gas at the corner service station might disagree.

In a real gas turbine, mechanical energy is changed irreversibly (due to internal friction and turbulence) into pressure and thermal energy when the gas is compressed (in either a centrifugal or axial compressor).Heat is added in the combustion chamber and the specific volume of the gas increases, accompanied by a slight loss in pressure.
