Self-Excited Codirectionally Magnetically Compensated Rotating Ranging Method

Figure 6

Attenuation of the peak-to-peak value in accordance with well spacing. (a) shows the attenuation process of magnetic field peak-to-peak value along with well spacing from 0.5 m to 20 m; (b) shows the magnification of magnetic field peak-to-peak value attenuation during the 5-20 m well spacing variation in (a).
