Latest Patents

Two of Gupta’s latest patent descriptions concern conductivity anisotropy estimation for inversion processing. One presents a method for improving estimates of horizontal conductivity, dip angle, azimuth, and anisotropy from dual-frequency transverse electromagnetic induction measurements. It uses initial estimates from multiple base frequencies as inputs to a trained neural network. The network is trained with modeled earth formations, synthesized instrument voltages, and known formation properties, enabling it to learn the relationship between initial estimates and known values.

The other method determines initial estimates of horizontal and vertical conductivity in an anisotropic formation. It uses electromagnetic induction signals measured with transmitters and receivers oriented along mutually orthogonal axes. The method calculates relative rotation and inclination angles, applies rotations to the receiver measurements, and uses the resulting magnitudes to estimate horizontal conductivity and an anisotropy parameter. It then derives vertical conductivity from those values.

Career Highlights

Gupta’s patent work combines electromagnetic measurement techniques with computational methods for interpreting subsurface formations. The described inventions aim to improve the accuracy of conductivity estimates, which are important in analyzing geological conditions around a wellbore.
