| titleOfInvention | Optimized determination thermal decay time |
| abstract | ABSTRACT A novel neutron burst timing, detection, and calculation method and apparatus are disclosed for a Thermal Decay Time Logging System. A neutron bursting regime is provided which includes a short burst, long burst repetitive sequence. After a short delay from the short burst, a first series of time gates is provided for accumulating gamma ray counts. After a relatively longer delay from the long burst, a second series of time gates is provided for accumulating gamma ray counts. The thermal neutron decay time constant ? and the macroscopic capture cross-section .SIGMA. of the formation are determined through an iterative procedure by which the formation ? is estimated from the second series of time gates which have been stripped of borehole decay counts determined from the first series of time gates. Similarly, the borehole T is estimated from the first series of time gates which have been stripped of formation decay counts determined from the second series of time gates. |
