Well completion is the last operation of well construction engineering and the beginning of oil production engineering. It covers all the technological processes that connect the wellbore with the reservoir in a certain structure after drilling is completed, including casing running, cementing, perforating, sand control, installation of production string and stimulation etc. It is a systematic engineering.

Based on our strong technical reserves and sophisticated service equipment, Hilong Oil Service & Engineering CO.LTD is committed to providing global customers with integrated drilling and completion technical solutions and engineering services.
