Abstract

A successful technique is being used to evaluate sandstone reservoirs for hydrocar- bons. The technique consists of crossplotting the shear wave travel time and the neutron porosity. The crossplot will produce a hy- drocarbon indicator based upon the relation- ship between the travel time and the neutron porosity. The sandstone reservoirs that are hydrocarbon productive will exhibit a great- er shear wave travel time than would be predicted from the neutron porosity. Those sandstone reservoirs that are non-productive exhibit a smaller shear wave travel time than would be predicted from the neutron porosi- ty. The technique can be applied in the cased hole as well as the open hole logging environment.
