Evaluation on reservoir rock and fluid characteristics: Determine the physical property of the reservoir rocks and its fluid characteristics contained accurately through complete wellbore rock physics and reservoir fluid information by wireline logging. The side well coring and the formation fluid sampling enrich the rock physics and reservoir fluid information after laboratory analysis

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.

Measure the formation pressure via cable pressure sampling instrument, sample the downhole formation samples, make lab PVT analysis and master the property of the reservoir fluid. Therefore, it is of great help for oil field development in later stage.
