Analysis of US Fracturing-Fluids Trends Offers Insight Into Changes Over Time

An analysis of thousands of fracturing treatments in major plays in the United States provides insights into how fracture designs have changed over time. All available data from FracFocus.org were collected, and each fracture treatment was classified into a set of standard hydraulic-fracturing-treatment types. This analysis of changes identifies changes over time in fracture type on the basis of seven broad categories—conventional, water frac, hybrid, energized, acid frac, gas frac, and matrix acidizing.

Introduction

FracFocus.org was launched in early 2011 to serve as the US national hydraulic-fracturing chemical registry. The registry is managed by the Groundwater Protection Council and the Interstate Oil and Gas Compact Commission to provide the public with access to reported chemicals used for hydraulic fracturing within their area. When this paper was written, nearly 26,000 wells had been reported on the website.

Although the FracFocus website was developed with the intention of disclosing to the public the chemicals injected downhole within a given area, the chemical-disclosure data sheets contain a wealth of technical data about hydraulic-fracturing-fluid systems.

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 163875, “Analysis of US Hydraulic-Fracturing-Fluid-System Trends,” by Christopher Robart, SPE, PacWest Consulting Partners, Michael Ruegamer, SPE, Kingsfield Consulting, and Alex Yang, PacWest Consulting Partners, prepared for the 2013 SPE Hydraulic Fracturing Technology Conference, The Woodlands, Texas, USA, 4–6 February. The paper has not been peer reviewed.
