AN INTERGRATED SOURCE-FREE METHOD AND APPARATUS FOR POROSITY DETERMINATION: NMR CALIBRATED ACOUSTIC POROSITY |
| 摘要 |
NMR porosity measurements made in a gas free-formation are used to calibrate acoustic measurements. The calibration parameters are then used in conjunction with estimates of shale content to provide improved estimates of formation porosity in shaly intervals which may include a gas. |
