An improved plunger mechanism apparatus to increase well flow production levels in sand based wells. The apparatus includes a first sensor, a second sensor, and a computer, preferably a programmed logic controller. By varying the flow rates of the two solutions, the concentration of the soluble compound can be varied as a function of the length of the channel. After the nonoriginal coating is applied onto the component, the cooling holes that meet a predetermined inspection criteria are reworked to remove the excess nonoriginal coating deposited in the outer shaped portion of the cooling holes. The technique includes monitoring a parameter affected by the operation of the seismic vibrator during the frequency sweep and based at least in part on the monitored parameter, determining a maximum driving force profile for the seismic vibrator. Each regional computer is associated with a predefined number of affiliated casino properties in a particular geographical region.
