IMAGE ENHANCEMENT FOR RESISTIVITY FEATURES IN OIL-BASED MUD IMAGE |
摘要 |
Resistivity images obtained by an imaging device in a borehole having oil- based mud may be of poor quality due to standoff variations, leakage currents and random noise. By processing the data using steps including median filtering, entropy equalization and bandpass filtering, the image quality can be considerably improved. |
