Abstract: A computer system presents information related to drilling operations using a computer display, the method comprising: for each of a plurality of drilling sites, obtaining chemical composition data of hydraulic fluids used in the drilling site, wherein the chemical composition data is obtained from a first data source, for each of the plurality of drilling sites, obtaining well yield data for the drilling site, wherein the well yield data is obtained from a second data source distinct from the first data source, matching the chemical composition data and the well yield data by drilling site, and displaying, on the computer display, a combination of chemical composition and well yield for the plurality of drilling sites. The matching might be based on drill site parameters, such as geographic location and/or geologic characteristics.

Abstract: An adaptive interference canceller for canceling an interfering signal corresponding to a delayed, frequency translated, amplitude and phase offset version of a transmitted signal contained in a composite received signal relayed through a relay system such as a satellite transponder. The canceller digitally downconverts the received signal and a local replica of the transmitted signal from IF to baseband, applies a variable delay and frequency compensation to the replica as a coarse delay and frequency correction, and tracks fine delay, amplitude and phase differences using an adaptive finite impulse response filter to generate a cancellation signal corresponding to the delayed and frequency shifted version. A minimum output power process produces an error signal that drives the variable delay and adaptive filter to minimize the power in the signal of interest to maximize cancellation of the interfering signal.
