LWD Sonic - Robust, Reliable and Accurate while Drilling

This paper looks at how LWD sonic technology benefits the client to get high quality sonic data while drilling to make fast, reliable real time decisions, focusing on how the unique design of the tool and each component allows for this to be achievable. An example from offshore China illustrates how the client used the sonic data for formation evaluation work in exploration and production wells due to the robust stability and ability to provide reliable and accurate data, where it was not previously achievable. In particular, paying attention to how in real-time the client achieved the optimum result by making real-time decisions in pore pressure evaluation and to proactively adjust the well trajectory.
