Introduction to Logging While Drilling (LWD) Technology

Logging While Drilling (LWD) is one of the most widely used logging technologies in China. It enables accurate real-time measurements of formation density and drilling formation conditions—such as directional data, formation characteristics, and drilling parameters—through the borehole. This plays a decisive role in reducing development costs and optimizing oil production.

Acoustic Logging Technology

Acoustic logging involves transmitting sound waves into the borehole and analyzing the acoustic response of the surrounding formations. This technique allows for the evaluation of formation properties and borehole conditions. It can reveal a wide range of reservoir and wellbore characteristics, and is particularly effective in estimating parameters such as pore pressure, permeability, anisotropy, and geomechanical properties of the rock.

Imaging Logging Technology

Imaging logging converts subsurface measurements into 3D visual representations using advanced computer processing. This provides a clear and detailed view of formation structures and related data. The advantages of this technology include high data acquisition efficiency, rich information output, and high resolution—making it especially suitable for complex petroleum geological environments.

Cased Hole Logging Technology

Cased hole logging enables continuous monitoring and measurement of formation data after casing has been installed. By collecting, organizing, and analyzing this data, it is possible to determine oil and water production rates and to accurately assess the saturation levels of hydrocarbons within the reservoir.

Radioactive (Nuclear) Logging Technology

Also known as nuclear logging, this method uses radioactive sources and measurements of rock physical properties to evaluate formation characteristics and identify oil and gas zones. Representative techniques include Natural Gamma Ray Spectroscopy Logging and Neutron Porosity Logging. These tools are fundamental in modern formation evaluation and reservoir analysis.
