Abstract: In a Digital Pressure Derivative Technique (DPDT) which uses convolution, an input signal including noise is convolved with a wavelet to produce an output signal which is a derivative of the input signal and which is substantially devoid of the noise. The DPDT can be used in many applications; however, in one such application, a pressure signal from a wellbore including noise is convolved with a special wavelet to produce an output signal which is the derivative of the input pressure signal, the output signal being substantially devoid of the noise. The wavelet is made from the unit sample response of a bandlimited, optimum linear phase Finite Impulse Response digital differentiator. The DPDT technique enables analysts to customize the differentiation based on the quality of the measured data without having to use traditional, subjective smoothing algorithms.

Abstract: A method is presented to estimate the productivity index, PI, and the well condition, s, of a pumping well utilizing the knowledge of pump runtime versus downtime. Runtime and downtime may be constantly and automatically recorded and transmitted to a central location. A model runtime is computed assuming the two unknowns, PI and s. The model is then compared with the actual runtime data. A nonlinear optimization technique is used to search for the unknown parameters such that the differences between the measured data and the numerically simulated data are minimized in a least-squares fashion. The proposed estimation procedure is an economical and accurate method for monitoring the behavior of a well resevoir system during runtime.
