Present development of TRANSFUSION, a novel time-dependent three-dimensional finite-element neutron and gamma diffusion code for the analysis of pulsed-neutron oil-well logs
- Nuclear Research Centre, Boeretang (Belgium)
The novel code TRANSFUSION is being developed with a view to analysing borehole logs in the field of oil exploration and production. TRANSFUSION describes the time-dependent neutron and gamma populations in the logging tool and the surrounding formation resulting from bursts of high energy neutrons by providing first-order solutions to the Boltzmann transport equation. In particular, the gamma responses in the near and the far detectors housed in the logging tool are calculated. TRANSFUSION was developed from the ANSWERS steady-state (three-dimensional) finite-element neutron and gamma diffusion code FENDER by extending it to become time-dependent. The code is an attractive alternative to the generally used rigorous Monte Carlo methods, being as user friendly but less time-consuming while remaining sufficiently accurate.
