COSL has experienced engineering staff and advanced MWD/LWD equipments, among which is DRILOG® to offer directional logging data with a variety of parameters, acquired during the drilling process, that can meet customer-demands for formation evaluation, well-placement, downhole drilling-tool state monitoring, and other related requirements.

The main services include:

the real-time engineering parameters, including inclination, azimuth, tool-face, drilling-tool vibration monitoring, drilling pressure (annulus pressure, caliper surveying, pressure-in-drill-string monitoring), and related requirements

the high-quality formation evaluation parameter data are saved in the downhole tools, and can be downloaded for post-operation analysis: natural gamma ray; resistivity; formation density; neutron porosity; Acoustic Logging While Drilling (ALWD); formation testing
