METHOD AND SYSTEM FOR DETERMINING FORMATION POROSITY |
| 摘要 |
<p>METHOD AND SYSTEM FOR DETERMINING FORMATION POROSITY (D#73,935-F) A method and/or system for measuring formation porosity from drilling response. It involves measuring a number of drilling parameters and includes determination of tooth dullness as well as determining a reference torque empirically. One of the drilling parameters is the torque applied to the drill string. I</p> |
