The algorithm of the optimal profile designing under the condition of minimizing of the energy consumption to overcome the resistance forces in the process of drilling string and casing column movement In the borehole with the specified starting and finishing points is considered. The movement of initially resting point mass under the action of gravity and friction along the previously unknown trajectory, which configuration is determined In the process of soMng the problem. Is chosen. Mathematical problem in the form of a variational principle of least time of travel is formulated. Examples of the well profile calculation, built on the basis of the proposed theoretical model with the use of field data, are given. Saving rate estimation is carried out.

The possibility of use the tectonic vertical faces of fracturing as channels by water flooding deposits is considered. Nearby aquifer water must be fed through them in the reservoir under the wave action. The laws of cracks development and the technology of reservoir wave stimulation are given. It Is noted that the technologies of vertical-lateral water flooding through the vertical cracks seem to be real.
