A companion paper is being made to show the graphical analyses for the wells that Sandia measured surface and downhole loads at various depths with a special downhole load cell.
This paper will provide an analysis of the operating conditions that were occurring that resulted in these downhole dynagraphs. Additionally, these operating conditions will then be entered in three available industry rod string design programs that include: QRod, SRod and RodStar to see how accurately these design programs predicted the actual, measured loads.
