This study evaluates in detail the expected theoretical log responses and the actual log responses within one stratigraphically controlled hydrate horizon in six wells spaced throughout the Kuparuk Oil Field. Detailed examination of the neutron porosity and sonic velocity responses within the horizon is included. In addition, the theoretical effect of the presence of hydrates on the neutron porosity and sonic velocity devices has been examined in order to correct for such an effect on the calculation of formation properties such as porosity and hydrate saturation. Also presented in the paper is a technique which allows the conclusive identification of a potential hydrate occurrence.
