"The Glauconite Formation in the Magallanes Basin of Southern Chile is a clay- and silica-rich formation with low permeability. As with many of the unconventional resources, the Glauconite Formation requires a hydraulic fracturing operation to enhance the productivity of the wells in this area.
Data and pertinent information of fracturing, completion, and reservoir quality parameters along with post-fracture production data were collected to initiate a database of nearly 70 wells, to be used to develop a better understanding of the fracturing behavior, optimize the well stimulation, and overcome the major barriers in the hydraulic fracturing of the Glauconite Formation. The database of Glauconite wells was used in this study to identify the key parameters of the fracturing design, completion, and reservoir quality that have the greatest influence on well performance in this unconventional reservoir.
This study also attempts to identify the best treatment fluid to maximize well performance and the effects of different values of the major fracture treatments and completion parameters. Statistical and sensitivity analyses were applied to identify the most effective parameters on the initial production, early recovery, and Estimated Ultimate Recovery.
Results of this work show that water fracs are superior to hybrid fracturing fluids. Total fluid and proppant volumes strongly affect well performance. Other completion and reservoir parameters were found to have a lesser impact on well performance in the Glauconite wells of Southern Chile"--Abstract, page iii.
