It fits water-based and non-conducting drilling fluid, guides the geosteering operations and identifies the geological properties of the reservoirs through the high-resolution borehole imaging, micro-resistance and acoustic aperture imaging.

Image position and sample selection point: the high-resolution borehole imaging displays the formation structure and sedimentary characteristics precisely, thus guiding the sidewall coring, the measurement of formation pressure and selection of the fluid sampling points; it could play a more important role, especially when the thickness of reservoir is lower than vertical resolution of the logging tool.

Evaluate the geomechanics in the life cycle of the reservoir. Measure and evaluate the geomechanics characteristics of the reservoir, which is of great importance to the reservoir evaluation. The cables and Logging While Drilling reduce the risks of drilling by measuring the borehole stability. Use three-dimensional sonic logging technology, and describe the anisotropy of the crustal stress of the reservoir.

The borehole earthquakes are the bridges connecting the geophysical exploration technology and the logging technology The borehole earthquakes could provide high-resolution, high precision depth and speed data, which can be used to generate the image and calibrate the geophysical exploration data and models. The adoption of real-time geosteering technology to guide the drilling operations has improved the drilling encounter ratio significantly.
