This issue marks the debut of the Hydraulic Fracturing Operations feature in JPT. While hydraulic fracturing has long been a feature topic, this year, we are branching this major area of interest into both this feature and a Hydraulic Fracturing Modeling feature, which will appear in the November issue of the magazine.

For this issue, reviewer Nabila Lazreq of ADNOC has selected three papers that reflect industry efforts to achieve new goals in production and sustainability. Paper 201450 investigates the potential of natural gas (NG) foam fracturing fluid to reduce the major water requirements seen in stimulation. The authors write that such requirements can be reduced up to 80% in some cases by the use of NG foams. Although modeling is used to reach their conclusions, the authors point out that NG foam fracturing fluids have great promise in operational scenarios in areas such as the Duvernay Shale.

Paper 203226 reviews the challenges and conclusions reached by an operator implementing multistage fracturing for the first time in a horizontal well in a UAE tight carbonate reservoir. A cross-disciplinary approach proved effective when conventional stimulation methods were not successful in this challenging formation.

Finally, paper 201611 returns to the topic of NG foams, investigating their utility as an alternative to fracturing fluids composed of nitrogen and carbon-dioxide foams. The pilot-scale study leads the authors to conclude that NG foams are effective fracturing fluids that exhibit stable viscosity at elevated pressure and temperature conditions.

We hope that you enjoy the inaugural Hydraulic Fracturing Operations feature. Feel free to access the complete papers, and others that reflect recent achievements of SPE conference authors, in the OnePetro online library.
