LWD provides real-time formation measurements during drilling to improve decision making. It reveals the nature of rock formations and identifies potential hydrocarbon locations. Resistivity, lithology, and porosity data acquired through LWD allows geologists to evaluate the formation before damage or invasion occurs. The measurements help geologists select casing points and detect and quantify zones of fluid in real-time. New IWD measurements detect fractures and dip. Integrating real-time drilling data with 3D seismic provides operators a clearer understanding of the well within the reservoir to make better decisions and reduce risk in complex or unknown areas.
