Daqing has a very cold climate with temperatures staying in the –25F to –30F during the winter. Because of the cold climate and the difficulty of keeping fracturing tanks warm in the winter, they mix all their fracturing gel at an indoor central facility and then truck the gel to the well site in insulated tank trailers. Gel is mixed each morning for all fracturing job that will be run on the same day. Even though the system has been installed as a fixed installation, the basic system was designed to be mobile.
