Ideally when controlling a rod pumped well, is it important to have often and accurate fluid levels. However in the absence of the availability of these measurements, fluid levels must be calculated using fluid properties and pressure gradients. An important part of those calculations is being able to correctly approximate the fluid load. The fluid load is the difference between the upstroke fluid load and the downstoke fluid load. in this paper the accuracy and validity of a methodology for computing fluid load lines and therefore fluid level is verified through the application of the fluid load line calculation to a set of field data, for which a fluid level is available for each stroke analyzed.
