CA 2582123
A method for compressing borehole image data is disclosed. In one exemplary embodiment, the method includes acquiring image data downhole, selecting a block of the image data to compress, applying at least one filter to the block, selecting a subset of pixels from the block, and quantizing each of the subset of pixels. Exemplary methods in accordance with this invention may advantageously provide for sufficient data compression to enable conventional telemetry techniques to be utilized for transmitting borehole images to the surface in substantially real time. Moreover, exemplary methods in accordance with this invention reduce data latency and the susceptibility to telemetry errors as compared to the prior art.
