Internal waves generated by a circular cylinder oscillatingin a linearly stratified fluid of limited depth. The images are obtained with syntetic schlieren techniqueFor vertical (a) and horizontal (b) oscillationswaves degenerate into 1-st and 2nd modes, respectively.The oscillation frequency is the same in both cases.

Simulations of an invaded zone in borehole drilling

The evolution of an invaded

zone drilling in water- and

oil-saturated sand formations

is studied by mathematical

modelling of hydrodynamic

processes in porous media

filled with a two-component

fluid. The use of hydrodynamic

modelling to interpret high-

frequency electromagnetic logs makes it possible to construct consistent geoelectric and hydrodynamic models for

formations with different fluid saturations.

C-salt concentration, S - water saturation, v(t) - rate of drilling, k(z) - permeability,H – hydrodynamic head
