Abstract
A method for minimizing damage to downhole equipment utilized during controlled pulse fracturing ('CPF') where an oil based thickened fluid is used as a tamp. A gelled oil based fluid overlies a CPF propellant device thereby creating a tamp. When the propellant contained in the device is ignited, this high viscosity gelled fluid prevents the remnant of said device and wireline from moving upwardly which minimizes damage thereto.
