Determining Net Lift And Bottom-Hole Pressure With A Dynamometer

In determining the net lift and bottom-hole pressure in a pumping well, the first thought that comes to mind is, "What equipment is necessary?" The dynamometer and its related equipment are the only tools required. The dynamometer test data necessary are the traveling valve check and the standing valve check. Although this sounds simple enough, it should be pointed out that there are several precautions which should be observed in taking these valve checks.
