New-generation sonic logging-while-drilling (LWD) tools are providing data that help reduce uncertainty and allow engineers to make effective, sound and timely drilling decisions. Sonic LWD tools provide accurate acoustic data that, in turn, are being processed to accurately determine pore pressure. When combined with seismic and other while-drilling data, this information helps geoscientists look ahead of the bit to the next geologic horizon and beyond.
