Hp Finite Element

Azimuthal electromagnetic wave logging-while-drilling (LWD) technology can detect weak electromagnetic wave signal and realize real-time resistivity imaging. It has great values to reduce drilling cost and increase drilling rate. In this paper, self-adaptive hp finite element method (FEM) has been used to study the azimuthal resistivity LWD responses in different conditions. Numerical simulation results show that amplitude attenuation and phase shift of directional electromagnetic wave signals are closely related to induced magnetic field and azimuthal angle. The peak value and polarity of geological guidance signals can be used to distinguish reservoir interface and achieve real-time geosteering drilling. Numerical simulation results also show the accuracy of the self-adaptive hp FEM and provide physical interpretation of peak value and polarity of the geological guidance signals.

We proposed a method that enables to deform a soft object using a linear Finite Element Method (FEM) in real-time. In the proposed technique, since the calculation amount is reduced to <I>O</I> (<I>n</I>) (<I>n</I>: number of nodes), grasping is enabled in virtual space. In this paper, we studied grasping of a soft object taking gravity into consideration. Some simulations using a stiffness equation containing gravity demonstrated the validity of our proposal.
