Course Description
This short course on Wireline Logging and Perforations provides an overview of wireline logging operations, measurement while drilling (MWD/LWD), and perforation techniques.
The first two days focus on open-hole logging, covering key tools such as PEX, LDL, CNL, GR, CALIPER, SP, and PI, along with MWD and LWD for real-time formation evaluation. Modern open-hole logging techniques, including Analysis Behind Casing (ABC), are also explored.
The remaining three days cover cased-hole logging techniques, including PLT, PSP, TDT, USIT, RST, CBL/VDL, and GR/CCL for production monitoring, well integrity assessment, and reservoir evaluation. Additionally, participants will gain hands-on insights into perforations, tubing punch operations, and the deployment of packers and plugs for well interventions.
