Summary
This case study details the application of NOV's refrac liner system, specifically designed for mature wells in the Bakken region. The document outlines the challenges faced by older wells, including limitations in stage spacing, stimulation pressure, and issues related to corroded casing. It explains how the installation of a liner casing and the optimization of stage spacing and fracturing pressures have led to increased production potential. The case study presents NOV's customized package solution, which includes the SURESET liner hanger system, Wet Shoe Sub, and SUPERDart. These components work together to enhance the refrac process by ensuring effective cement separation and maintaining pressure integrity. The results indicate that NOV's approach has successfully improved the capabilities of refrac operations, leading to reduced costs and enhanced return on investment. The study emphasizes the importance of selecting the appropriate liner hanger system to achieve optimal outcomes in refrac projects.
