Pulsed neutron capture log evaluation using synthetic base logs

The evaluation of recompletion opportunities using pulsed neutron capture (PNC) logs is made easier by preparing predictive synthetic logs using openhole log data. Wellsite personnel can assess drainage quickly by comparing the actual log with the synthetic expected response, thus avoiding time-consuming trial calculations. A simple computer technique is presented for creating synthetic base PNC logs using the original openhole log information. 5 refs
