Resumen

Many researchers have developed equations to characterize hydraulic fractures assuming they are symmetrical with respect to the well, since symmetrical fractures are less likely to occur. Therefore, since there is no direct analytical methodology that allows an adequate interpretation using the pressure derivative function to determine the fracture asymmetry, the position of the well with respect to the fracture, fracture conductivity and half-fracture length. For this reason, the TDS methodology that uses characteristic lines and points found in the pressure and derivative log-log graphs is presented here to develop analytical equations used to determine in a simple, practical and exact way the aforementioned parameters. The technique was satisfactorily verified with synthetic problems.
