Measurement of continuous permeability profiles on a routine basis has become possible through recent advances in wireline logging hardware and software. Continuous permeability profiles allow geologists and reservoir engineers to better characterize their reservoirs and to more efficiently complete and manage the production of the hydrocarbon reserves. One of the most promising methods for the calculation of continuous permeability information is the use of Stoneley wave data acquired using a monopole acoustic device. This paper presents the results of a case study conducted for Petroleum Development Oman. In this study, permeability was determined from Stoneley wave data from the Sarmad-1H2 and Sarmad-2H1 wells that penetrated the carbonate reservoirs of the Ara Group of Oman. The Stoneley-wave derived profile was compared with permeability data from other sources; such as, cores, wireline pressure tests, and the interpretation of nuclear magnetic resonance measurements. The results demonstrated the validity of the methodology and showed that Stoneley-wave data can be used on a routine basis to obtain a continuous permeability indication for completion evaluation purposes. The method has great potential in permeability prediction.
