Embodiment Construction

[0050] Specific embodiments of the present invention may be described below with reference to block diagrams and operational illustrations of methods. It will be understood that each block of the block diagrams and their operational illustrations, and combinations of blocks of the block diagrams and their operational illustrations, can be implemented by both analog and digital hardware and computer program instructions. Such computer program instructions can be provided to processors of general purpose computers, special purpose computers, ASICs and other programmable data processing systems. The instructions executed create the structures and functions for implementing the actions specified in the block diagrams and operational illustrations. In some alternative implementations, the functions / acts / structure noted in the figures may occur out of the order noted in the block diagrams and operational illustrations. For example, two operations shown as occurring in succession ...

Abstract

A method for determining a pump card for a well. The method comprising: obtaining a first set of data points, wherein the first set of data points comprise a first set of polished rod position data points of the well and a first set of polished rod load data points of the well; and calculating a first data point of a pump position and a pump load using the first set of data points. The calculating occurs before the well moves through a first complete stroke cycle.

[0003] Statement on Federal Funding for Research and Development [0004] Not applicable. [0005] Appendix Reference [0006] Not applicable. technical field [0007] FIELD OF THE INVENTION The invention disclosed and taught herein relates generally to pump diagnostic methods, and more particularly to real-time and near-term diagnostics for use with rod pumps and similar well pumping systems. Real-time pump diagnostic techniques and approaches. Background technique [0008] Modern pump diagnostic techniques for straight wells originated with Gibbs in 1966 [Gibbs S. G et al., Journal of Petroleum Technology, Vol. 18(1), pp. 91-98 (1966)]. Gibbs used a separation of variables approach to generate an explici...
