<p class="Normal1"><strong><em>Abstract: </em></strong><em>Partial Differential Equations (PDP) Laplace equation can be applied to the heat conduction. Heat conduction is a process that if two materials or two-part temperature material is contacted with another it will pass heat transfer. Conduction of heat in a triangle shaped object has a mathematical model in Cartesian coordinates. However, to facilitate the calculation, the mathematical model of heat conduction is transformed into the coordinates of the triangle.

The problem of determining reservoir properties (porosity, permeability) of gas layers developed in the depletion mode, whose rocks are subjected to creeping deformation with the Abel core, is considered. In order to determine the parameters that characterize reservoir properties of the reservoir, the authors indicate the possibility of using an appropriate numerical solution to the problem of determining the theoretical values of the reservoir volume-weighted average reservoir pressures over time, obtained using the finite difference method.
