Technology and development

COSL has five research instates, they are Geophysics, Drilling, Well-tech, Oilfield chemical and Oil field optimization, the five research institutes mainly engaged in geophysical survey, well drilling, completion and logging, oil field stimulation equipment study and related technology research as its main work, at the same time get in touch with more than 30 entities such as universities and research institutes to work out the imaging well logging technology, oil and gas formation test instrument of the third generation model, seismic data collection system of high accuracy, high temperature and deep well fluid and well completion system, multi-hot- fluid viscous oil production, oil well acidizing and fracturing technology etc.

A lot of core technologies have been applied successfully to the exploration and development of the oil and gas field and gradually form integrated technology research, product manufacture and technical support as one innovation system.
