In this paper

we investigate the feasibility of applying optically stimulated luminescence (OSL) method to oil and gas exploration

based on what has been achieved in this application with thermoluminescence (TL) method. Wave bands of 514

600

685

740 and 800 nm were used to stimulate the samples in the test

with 5 s interval between each data-collecting time from 5 s to 35 s. The results showed that from the same sample

a number of photon response levels could be stimulated at different laser energies

and there were electronic dap in different energy traps by OSL or TL luminescence curves.
