Abstract
Borehole image data is compressed and transmitted to the surface one pixilated trace at a time. The compression methodology typically includes transform, quantization, and entropy encoding steps. The invention advantageously provides for sufficient data compression to enable conventional telemetry techniques (e.g., mud pulse telemetry) to be utilized for transmitting borehole images to the surface. By compressing and transmitting sensor data trace by trace the invention also tends to significantly reduce latency.
