General Meeting: Matt Paradeis – Assessing the Impact of Oriented Perforations and Frac Plug Performance in DJ Basin: A Case Study from Chevron Leveraging DarkVision Technology

Assessing the Impact of Oriented Perforations and Frac Plug Performance in DJ Basin: A Case Study from Chevron Leveraging DarkVision Technology

Chevron Rockies Business Unit began an effort in late-2022 to evaluate the effectiveness of its perforation design using modern, solid-state acoustic imaging technology. This evaluation uses DarkVision Technologies’ imaging tools deployed on coiled tubing after hydraulic fracturing, between well cleanout and running production tubing. An initial study was designed with three wells in the DJ Basin of northeastern Colorado using three different perforation schemes of various orientation. All were approximately 10,000’ laterals with dissolvable frac plugs for stage isolation.  

The three-well study revealed eye opening information regarding the frac plugs performance, both during the initial setting and during pressure pumping. Furthermore, the expected downstream impacts resulting from these findings were also observed and analyzed. This case of study highlights the key findings of the completed study, the mitigation strategy implemented, and the results obtained from such implementation.

Keynote speaker:

Matt Paradeis is senior completions engineer work for Chevron based in Denver, and primarily focusing on the DJ Basin. After graduating from Missouri University of Science & Technology with a degree in petroleum engineering, he began his career in Houston with Chevron in 2012 working as a rock mechanics specialist focusing on near-wellbore and reservoir scale geomechanics. He’s spent 8 years working deepwater assets in the Gulf of Mexico including 3.5 years as a field engineer offshore executing completions and drilling operations. He also has experience as a deepwater drilling engineer, project engineer for a 20,000psi mobile offshore drilling unit and process safety engineer. He joined the Chevron Rockies Business Unit in July 2022.
