STANDOFF SPECIFIC CORRECTIONS FOR DENSITY LOGGING

摘要

Methods, systems, devices, and products for estimating a parameter of interest of a volume of an earth formation. Methods may include correcting a measurement relating to the parameter of interest by a downhole tool using at least one correction model determined from a plurality of predefined models. The at least one correction model may be determined based on an estimated borehole standoff of the tool from the borehole wall that is associated with the measurement. Correcting the measurement may include determining a correction factor using the correction model and applying the correction factor to the measurement. Each of the plurality of predefined models may be associated with each of a plurality of standoff bins, wherein each of the plurality of standoff bins is defined as a mutually exclusive interval of distance values from the downhole tool to the borehole wall.
