Taber et al. [3] shows that 60 % of carbonate rocks were intermediate-wet, 28% were oil-wet and 8% were water-wet.Consequently controlling wettability is become a great challenge in oil and gas industry.

Intelligent Finding Satellite system use communication header $ IFS (Intelligent Finding Satellite), the specific format of data frame is
$ IFS, <1>, AZ, <2>, EL, <3>, V [Cr] [Lf]
Where <1>: the azimuth, range 0-360 degree, accurate to 0.1 degree, clockwise direction is to increase angle; <2>: the elevation, range of 0-90 degree, accurate to 0.1 degree, the horizontal direction is zero degree, the zenith direction is 90 degree; <3>: the polarization angle, range -90-90 degree, accurate to 0.1 degree, if the polarization angle is positive, the sign bit is space.
