METHOD FOR GAS ZONE DETECTION USING SONIC WAVE ATTRIBUTES |
| 摘要 |
A method for determining on a real time logging while drilling (LWD) basis gas within earth formations traversed by a borehole. Continuous LWD acoustic measurements are recorded and processed including coherent energy and attenuation attributes to detect downhole gas zones and kick during drilling operations. |
