... sources. As fresh water for fracturing operations and well interventions becomes less available, operators are forced to use alternative water sources such as recycled flow-back water, produced water, and even ‘grey water’ from wastewater treatment plants. In some instances, recycled water is sold from...

This paper describes the new friction reducer and the benefits of using it in unconventional shale formations. Also included is a case history to demonstrate...

... bromide, and is thermally stable. The friction pressure study utilized fresh water and several brines, including 7% KCl, 9.7 ppg NaCl and 11.4 ppg CaCl 2 . The fresh water systems were pumped through 1½ inch diameter coiled tubing and straight pipe. For the heavier brines, a small scale flow loop...

... and large-scale flow loops have been utilized in this study. The small-scale flow loop includes a ½-in. OD smooth coiled tubing while the large-scale flow loop includes 2⅜-in rough CT. Elevated temperature tests and salinity tests are conducted using optimum concentrations of drag reducers in fresh water, 2...
