Title: Application of High-Resolution Fiber Optic Data to Enhance Completion Design Major: Petroleum and Natural Gas Engineering Date: Thursday, April 18, 2024 Time: 4:00 PM Place: 141 Engineering Science Building


Well stimulation is a technique that has been used in the industry for decades, and with the ability to drill wells horizontally the practice has become more valuable and effective than ever before. Its use is consistently being optimized and completions design plays a crucial role in the recovery of hydrocarbons. Several different downhole tools and measurements have been used to optimize these designs and with the continued advancement of technology available, more data has become available to better understand the events occurring beneath the surface. Logging tools provide a vast amount of information about a well and the formations it encounters. Properties and characteristics of the formations can be determined, and several parameters can be analyzed for efficient design. Using the image logging tools, acoustic or electrical, fractures can be identified based on observation of dips in the well log. These dips can represent a fracture and the depth, angle, and azimuth can be key to determining fracture properties and creating an optimal completions design. Fiber optics are also one of the tools being explored to understand and optimize the completion designs. This fiber optic data is recording events that transpire during a frack job with measurements that include temperature and acoustic data. Using well log data along with the fiber optic data can lead to a better understanding of the events occurring downhole. The Marcellus Shale Energy and Environmental Laboratory (MSEEL) research group provided an analysis using this fiber optic and well log data over two projects, MSEEL 1 & MSEEL 2. MSEEL 1 is already completed, and the conclusions drawn from MSEEL 1 were used and applied to MSEEL 2 which is the current project. The goal was to increase productivity while lowering costs by analyzing the vast amounts of data available from well logs and fiber optic data. This data will be analyzed, and completion and production data will be used to illustrate how this material can lead to an optimal completions design.
