High-definition imaging where not previously possible

The FMI-HD high-definition formation microimager takes high definition to a new level. The visibility and interpretability of small features are increased by up to 4× for all environmental conditions, even across extreme variations in formation resistivity or resistivity anisotropy between the formation and mud.

This means that water-based mud environments and some oil-based muds that cannot be clearly imaged with conventional microresistivity imaging technology can now be seen in great detail.

Defining high definition down to 10 um

The visibility and interpretability of small features on images from the FMI-HD microimager are significantly increased over that of conventional images for all conditions, even for features that are much smaller than the 0.2-in nominal resolution, depending on the resistivity contrast with the surrounding formation, however small.

The HD electronics of the FMI-HD microimager are sensitive enough that fluid-filled fractures less than 10 um in width are frequently imaged. The size of small features is quantified from the current flow to the button.
