WFS Well Plant Logging Instrument

Overview


    • WFS well plant logging instrument is a new generation of petroleum exploration and development equipment developed to meet the on-site logging needs of shale gas drilling based on years of accumulated professional technology, and relying on the advantages of the company’s scientific and technological talents and strong industrial foundation in Shanghai. It is leading in the overall design and manufacturing technology in China, and reaches the international advanced level. 


  • WFS well plant logging instrument uses a set of logging instruments to achieve simultaneous logging of two or more wells on site. It is not only equipped with a conventional fast chromatograph and a CAN bus data acquisition system, but also is equipped with wireless sensors and a wellhead chromatography system, fully meeting the logging tasks in the well plant operation mode.

Features 


    • A working area for logging personnel is available in the logging instrument room to make the working environment more comfortable. A chromatograph installed at the wellhead to reduce pipeline delay, and achieve faster gas measurement results. 


  • Wireless sensor systems to reduce field wiring and meet rapid installation in multiple wells Reduce on-site logging personnel and reduce logging costs. Dual servers at the well pad and base to meet the requirements of remote logging.
