método e aparelho sem uso de fonte integrada para determinação de porosidade: porosidade acústica calibrada por nmr |
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. |
