Paper Number: SPE-220878-MS
... reservoirs of Surat basin, eastern Australia, have been fracture stimulated for more than a decade with ever evolving treatment designs. In a recent fracturing campaign, critical design changes led to improvements in well performance and in mitigating issues related to proppant flow back and fines production...

... and single trip multi-zone frac-pack completion systems. Despite some of the successes, the project economics of vertical fractured wells in the lower Wilcox remains challenging due to low recovery factors (8 – 20%) and low EUR/layer. This paper describes an alternative lower completion concept...

Paper Number: SPE-221006-MS
... Abstract Hydraulic fractures are often assumed to immediately stop growing once pumps are shut off after fracturing treatments. However, fluid momentum and rock properties may allow propagation to continue temporarily post-shut-in. The objective of this study is to determine if and under what...

... for their ability to extract heat from hot, dry rock. However, issues remain in assuring safe drilling and proper fracturing owing to a lack of knowledge of damage factors and fracture sequences, both of which are crucial for regulating crack propagation. Conventional laboratory approaches often fail to capture...

... (ACGS) has been proposed to enhance heat production in this research. The ACGS incorporates a hydraulic fracture, partitioned by a horizontal insulator for vertical zonal isolation of fluid flow in the fracture, into the closed-loop system's fluid circulation. Since working fluid flows through...
