Logging While Drilling (LWD) LWD is a technique used in oil and gas exploration to collect real-time formation evaluation data while drilling a well. It is an essential part of modern drilling operations, providing valuable information about the subsurface without requiring separate wireline logging runs. LWD involves the use of specialized downhole tools that are integrated into the Bottom Hole Assembly (BHA). These tools measure various properties of the formation and transmit the data to the
