Improved Radiation Transport Modelling for Borehole Applications

Funded under: FP5-EAECTP C


The high level aim of this project is to increase the ultimate recovery from producing hydrocarbon reservoirs, at minimal environmental cost, by more effectively pinpointing missed hydrocarbon pockets and thereby enabling appropriate reservoir management strategies for extracting the resources remaining in the reservoirs. To achieve this, the project is focussed on improving the interpretation of the nuclear logging measurements which are used to locate remaining hydrocarbon resources behind casing but away from existing producing zones. This will be done by increasing the accuracy, precision and ease of use of the radiation transport modelling codes available to the petrophysicist interpreting the logs. Greater accuracy will result from the development of improved nuclear data libraries specifically geared to the borehole environment and the type of radiation transport model used, while improvements in the computational efficiency of stochastic codes will yield greater precision for a given computational effort. A front end enabling selection of the most appropriate code for a particular application will render the new neutron log interpretation technology accessible to the practising petrophysicist
