IMAGING FLUID COMPRISING A PLANT-BASED OIL, AND METHOD FOR SUBSURFACE IMAGING IN A BOREHOLE
The present application pertains to an imaging fluid and a method for subsurface imaging, such as that of electromagnetic imaging, comprising introducing said imaging fluid into a borehole. The imaging fluid comprises a plant-based oil, a drilling fluid weighting agent and a saturated fatty acid, and has the properties of a dielectric permittivity of from 2 to 5 and a density greater than water. In one example, the imaging fluid is comprised of: canola oil or castor oil 40 - 75%, stearic acid 1 - 10%, and barium sulfate 15 - 45%, all percentages are weight by total weight of the imaging fluid.

WELLBORE IMAGING TOOLS AND METHODS FOR WATER MITIGATION IN A BOREHOLE
A water exclusion apparatus for a geophysical imaging tool is configured to be placeable around an exterior surface of the geophysical imaging tool and is operable to force at least some water away from the exterior surface of the geophysical imaging tool. The water exclusion apparatus is, for example, expandable.

An apparatus for ground penetrating radar includes an antenna disposed within a sleeve. The sleeve includes a radar-absorbing material for attenuating the amplitude of incident radar waves. The sleeve has an aperture for permitting radar waves ω pass into and out of the sleeve. A method for surveying a formation using ground penetrating radar includes rotating the antenna and sleeve while keeping the antenna and sleeve longitudinally stationary, and recording data including the amplitude of waves received by the antenna and the position of the aperture when such waves are received.
