Natural gas — Upstream area — Determination of drag reduction in laboratory for slick water

This document specifies a method for the determination of drag reduction of slick water, which is mainly used to evaluate the drag reduction performance of slick water. This document uses the pipeline method to evaluate the drag reduction, which is currently recognized as the best method to evaluate the drag reduction performance. This document describes the device, experimental conditions and operating steps in detail. The drag reduction value obtained by evaluation according to this document can effectively represent the on-site drag reduction performance.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
