SpecialReport: Well Stimulation & Completion Technology field test was remarkably successful. High current was transmitted into the bottom of the well while conducting the plugand-perf fracturing treatment, and all operations were carried out in a safe and environmentally sound manner. Measurement A provided several positive results and observations. A cursory look at the signals being received by the receiver arrays indicated an e-field signal was being carried to surface, and the waveform was very similar to the input transmission. In addition, while the EM signals were extremely small, they matched the forward modeling expectations very well. The final step was removing the noise, differencing the data, and inverting the results for visualization. While noise suppression processing continues to be worked, several preliminary inversions have been performed on the data from each receiver using basic filter techniques. Most of the preliminary analysis and inversion work has been completed on the "C-minus-B" differenced data, representing the two measurements taken immediately before and after placing de- tectable proppant in stage 16. This inversion shows promising results. Using a cut-off representing the distinct change from background response to relatively high signal strength shows a symmetrical length, height and width of propped rock.
