Abstract:
A method of enhancing fluid production from a well is provided. A downhole plunger having the maximum permissible outer diameter for the well is installed in the well. Methods and apparatus for determining the maximum permissible outer diameter for a downhole plunger for use in the well are provided.

Claim (Index 8):
A method of determining the maximum permissible diameter for a downhole plunger that can be used in a well, the method comprising the steps of:\n evaluating a plurality of different plunger outer diameters to determine whether plungers having at least two of the plurality of different plunger outer diameters can travel freely in a tubing of the well by repeating, for the plurality of different plunger outer diameters, the steps of\n (i) selecting a first one of the plurality of different plunger outer diameters for analysis; \n (ii) dropping a drive plunger and a first measuring sleeve within the tubing of the well, the first measuring sleeve having the first one of the plurality of different plunger outer diameters, and the drive plunger having a diameter that is smaller than the first one of the plurality of different plunger outer diameters and being positioned below the first measuring sleeve in the tubing; \n (iii) if the first measuring sleeve becomes lodged in the tubing, concluding that a downhole plunger having the first one of the plurality of different plunger outer diameters cannot travel freely within the tubing of the well and using the drive plunger to dislodge and surface the first measuring sleeve; or \n (iv) if the first measuring sleeve does not become lodged in the tubing, concluding that a downhole plunger having the first one of the plurality of different plunger outer diameters can travel freely within the tubing of the well; and \n concluding that the maximum permissible diameter for a downhole plunger that can be used in the well is equal to the largest one of the plurality of different plunger outer diameters that will still allow a plunger to travel freely in the well.
