<p>The present invention relates to a pumping system and method for drawing or pumping subsurface fluid (e.g., gas, oil, water, etc.) from a well, particularly a gas well. The pumping system of the present invention includes a pump which displaces fluid in a well into a string of hollow sucker rods during the downward stoke of the pump. The string of hollow sucker rods extends generally to the surface so that the fluids can be directed to collection equipment on the surface.</p> |
