Abstract
A compression scheme for reducing the amount of data that must be transmitted uplink from a formation test while drilling apparatus. Periodic samples are taken within the formation test apparatus and prior to transmitting data uplink, the samples are analyzed to generate curve fit parameters that define a curve that most closely fits the sampled data. A minimal set a data points, time variables, and curve fit parameters are transmitted to the surface where the transmitted data is used to reconstruct the formation pressure test curve. A quality of fit value is also transmitted with the minimal data set as an indication of the quality of the fit between the reconstructed data and the actually sampled data points.
