    Dual Lateral Logging Tool


    Introduction:


    Dual Lateral Logging Tool

    STSX89-200D dual lateral logging tool adopts new technologies such as multi-layer shielding, constant power, and multiple feedback control, which improve formation resistivity measurement range and accuracy. There are two modes each for deep and shallow lateral measurements, including shallow standard mode StdSh, shallow enhanced mode EnhSh, deep standard mode SrtnDp, and deep Groningen mode GrtnDp. STSX89-200D dual lateral logging tool accurately reflects formation resistivity changes, ensures correct logging under ordinary wellbore conditions, and better reflects formation intrusion zone under large wellbore and high salinity well conditions. Deep Groningen mode not only corrects the Groningen effect but also accurately measures the formation resistivity near casing ends.
