An uninterrupted economical supply of frac water is critical to the successful development of the Horn River Devonian shales. and Apache have progressed our water supply from tank truck delivery of fresh surface waters to an integrated, subsurface saline water treating and distribution system. The current system is designed to deliver water at a rate of 16 m3/min to a maximum daily volume of 16,000 m3 or enough water for 3–4 fracs per day. This presentation will discuss our experiences with fresh surface waters, the design and implementation of the pilot plant and the design, construction and operation of the full scale sour water processing plant. Another aspect that will be discussed are the water source wells including geology, drilling, completion and high volume lift systems.
