Integrated high-pull wireline conveyance systems accelerate access to well profiles ///

Early this year, tension modeling of planned formation logging and sampling runs—in a highly tortuous deepwater Gulf of Mexico (GOM) well—indicated that extreme normal logging tensions up to 20,900 lbf would be likely. Conventional high-strength wireline cables allow only three pull cycles at a maximum of 21,000 lbf. If a toolstring became stuck, and additional pull cycles were required to free it, or if instantaneous pulls exceeded the cable’s safe working load, the operator would have faced a very costly fishing operation and the potential loss of vital reservoir information.
