Intelligent Analysis Program Applied to Production Logs in Oil and Gas Wells

Abstract

Basic Production Logging can be interpreted in intermittent wells using the intelligent analysis program presents in this work, called PAINTWELL, which permits to use of same string configuration than a conventional Production Logging. This program can be performed in layered reservoir, determining the flowrate and type of the fluid for each production zone. The use of Artificial Neural Network as integrated part of this analysis program, provides a powerful tool to describe how downhole logging and advances in computer processing & interpretation data could spearhead the transformation that can take place in production logging with use of this new technique. This methodology should aid the production and reservoir engineering to solve recovery problems during the well life. The results of the production log using the PAINTWELL method is very similar to measurements using test separator in production facilities for each single perforated interval. This program was applied successfully for a typical intermittent well, which produces oil with high water cut using a gas-lift completion system.

Vibration Resonance Spectrometry (VRS) for the Advanced Streaming Detection of Rotor Unbalance

“…Historically, accelerometers (vibration sensors) have been used for decades to detect problems in assets in many types of industrial problems that result in higher vibration levels, which can be precursors to failure [1][2][3][4][5][6]. Perhaps the greatest challenge for conventional vibrational surveillance of assets is the inherent "seesaw" effect between the sensitivity for catching incipient degradation mechanisms and their false alarms.…”
