Paper Number: SPE-193734-MS
...-processing tools re-order this information to generate input files for the core CSEM processing routine as used for marine CSEM surveys. In addition, data sorting is such that receiver channels recorded on the high frequency (HF) boards of the acquisition can be processed with the current signal monitored on...

... antenna length will become shorter than that in free space. For example, when the frequency of waves is 200 MHz, the wavelength in the free space is 1.5 m, and in this case, the optimal length of dipole antenna is 0.75 m. In contrast, the wavelength in the reservoir ( ε r =4 and μ r =1) turns into...

.... Bogdanov et al. 2011 ). In these first studies the important technical question of the antenna interaction with reservoir at variable physical state has not been considered. Here we introduced the simplified model of this interaction and use it in computations of optimal EM field frequency to be chosen for...

... cases the steam injection is not a good alternative, especially, for tar sands. A better suited technology may be electromagnetic heating (EMH) assisted oil recovery. Different physical mechanisms underlie the heating according to the frequency of electromagnetic (EM) field. For instance, low-frequency...

..., one of them is based on electrical technology. One solution studied by Total to reduce viscosity when steam injection isn’t possible or efficient, is to use Radio Frequency heating. The electromagnetic waves have the capability to heat immediately deeper than steam. To improve efficiency of this...
