China Oilfield Services : COSL promotes overseas technical services of high-end logging equipment

China Oilfield Services Ltd ("COSL" or the "Company") has recently completed high-end logging operations for 3 wells commissioned on an ad hoc basis by a Canadian company within 5 days. These operations involved conventional well logging, electronic imaging, high-definition sensitivity and cross-dipole acoustic array logging. COSL's self-developed Enhanced Logging Imaging System ("ELIS") accomplished these operations on the every first try and fulfilled the client's requirement. These operations had been secured primarily due to the comprehensive technical capability and reasonable service rate of ELIS which had been introduced earlier to the Canadian market.

ELIS is now being actively promoted in the overseas market, boasting its years of experience, comprehensive technology, high-efficiency service and low cost. In the UAE in 2014, ELIS covered "Grand and Small Slams" of conventional well logging projects and cross-dipole acoustic array logging without operating loss time that won client's endorsement. In Indonesia, Company used ELIS collaborating with other service companies and successfully completed rotary sidewell coring in a Sumatra region, as a flexible service model creating a new growth driver for the Company.
