... bottomhole samples. Ideally, running an induction tool requires non- or low-conductive borehole fluid uniformly distributed in the borehole. This may not always be achievable under production conditions. In this study, the following were investigated: The slimhole induction tool was first tested...

... closed or semi-infinite, homogenous or naturally fractured systems. Uniform flux, infinite conductivity and finite conductivity models are considered. The fractures may be of different properties and unequally spaced along the horizontal wellbore. This model is validated using a numerical simulator...

... Abstract We present in this paper the results of measurements of the complex dielectric permittivity and electric conductivity in three different porous media, made from unconsolidated acid-purified quartz sand and glass grains. To ensure the generality of the results, we use sand and glass...

... with low permeability, reservoir M of Laojunmiao oil field (the oldest oil field of China). The average permeability of reservoir M is 24.2 mD. The use of waterfrac to the permeable reservoirs is a different scenario from that to tight reservoirs because the higher fracture conductivity is required...
