| titleOfInvention | MEASUREMENT OF FLOW PARAMETERS BY DRILLING NMR |
| abstract | A method for measuring the formation fluid flow in a natural occurrence using an NMR logging tool that is placed in the well, using a modified sequence of recovery pulses during saturation or angiography of the passage time to mark the spins in the formation, at least two measurements of marked spins as they propagate toward the well under negative differential pressure conditions, allowing for the determination of The fluid velocity from which the permeability can be determined. Also disclosed are technologies for performing the method under drilling conditions with both positive differential pressure and negative differential pressure. |
