A new method has been proposed to determine the just drawdown speed based on the rotating impeller domain in the CFD simulations.
The assumption that the liquid production is not affected by the higher wellbore pressure or smaller drawdown is based on the close analysis of the daily production data of the well.
An American drawdown must be based on a buildup of capable Afghan forces.
"Any further drawdown will be based on conditions on the ground and the recommendations of our commanders," he said, "and they must not jeopardize the hard-fought gains our troops and civilians have made over the past year".
A comprehensive model, coupling the fluid flow in the reservoir and the wellbore pressure drawdown, was developed based on potential functions and solved using the numerical discrete method.
But he noted, "I do not advocate ending our involvement immediately and any drawdown should be based on conditions on the ground".
The WFT data analysis can also be used to assess mobility values from the drawdown, the buildup or both, based on analytical solutions of the diffusivity equation initially developed for the well test analysis.
While the number of troops fluctuates based on the drawdown in Iraq and the troop increase in Afghanistan, as of June 2010 there were approximately 88,000 troops in Iraq and DOD estimates that the number of troops in Afghanistan will increase to 98,000 by the end of fiscal year 2010.
Any further drawdown of U.S. troops will be based on conditions in Iraq and the recommendations of our commanders.
This new model is used to estimate four aquifer parameters including the magnitude and directions of major and minor principal transmissivities and storativity based on the observed drawdown-time curves within a minimum of three non-collinear observation wells.
The study of Christensen [Christensen, S., 2000. On the estimation of stream flow depletion parameters by drawdown analysis. Ground Water 38 (5), 726 734], based on the solution of Hunt [Hunt, B., 1999. Unsteady stream depletion from groundwater pumping. Ground Water 37 (1), 98 102], analyzed three streamflow depletion parameters T, S, and λ of a simplified stream-aquifer system.
