A New Method for Real-Time LWD Data Compression

Free registration required

Executive Summary

Logging While Drilling (LWD) is an advanced drilling technology in oil/gas exploration and development, which was developed to increase drilling efficiency and decrease drilling cost. The real-time logging data transmission by the limited transmission bandwidth is a key technology in LWD. Compressing logging data by some algorithm is an evident method to enhance data transmission. This paper introduces a novel LWD data compression method on the basis of Differential Pulse Code Modulation (DPCM).
