This is viewing the wellbore from the side The colors shaded from white to black represent 0 to -50 fpm indicating downflow. The yellow to maroon shading indicates increasing velocity from 0 to 110 fpm As expected the low side of the wellbore indicates some downflow while the upper portion of the wellbore indicates upflow Center of wellbore 2015 HALLIBURTON.

Chi Modeling Logging Simulation Software Service When difficult logging conditions result in missed zones of openhole information, operators can literally "fill in the gaps" with the Chi Modeling

57 Chi Modeling Logging Simulation Software Service When difficult logging conditions result in missed zones of openhole information, operators can literally "fill in the gaps" with the Chi Modeling postprocessing service. Chi Modeling software is able to predict triple-combo or even quadcombo openhole data with a high degree of accuracy using input data obtained from two sources: a capture pass of a pulsed neutron tool, and a known triple-combo or quad-combo data set from a neighboring well. Chi Modeling software generates reliable openhole logs by assigning a processing weight to input variables until the plot indicates a reasonable match with openhole data from a reference well. The technique helps operators to better evaluate their reservoir when data is lacking due to borehole conditions, missing LWD sections, old wells, or other factors HALLIBURTON.
