  • Recent advances in well logging and formation evaluation

    S. Prensky

    Advancements in logging and formation evaluation during the past year included conceptual designs for new logging tools, field testing of new or modified logging devices and improved characterization of previously introduced logging tools gained through modeling, field experience or new processing and interpretation methods. WIRELINE LOGGING Logging platform. Halliburton introduced its new PC-based LOGIQ* logging platform. Comprised of a surface system and a new “quad-combo” downhole toolstring, this system is configured to run all open- and cased-hole log-acqusition and interpretation services. The new quad-combo string is lighter and shorter than the previous generation and is rated to 350° F and 20,000 psi. The ethernet-based communication protocol allows a fivefold increase in uphole data capacity. Resistivity logging. New commercial logging tools undergoing field tests include array-resistivity and microresistivity devices. Also, the conceptual design for an azimuthal laterolog capable of resistivity imaging was proposed.
