In the article the development of a mathematical model describing the PRC is studied on the base of pressure recovery curve method.Detailed processing of the pressure recovery curve made it possible to determine the deterioration of reservoir permeability in many wells. Here two methods are considered - stationary (steady conditions of selection) and non- stationary.The article proves that the use of these methods allows to develop a mathematical model to increase the determination of this task.On the base of numerical simulation, the following facts had impact on the results of the pressure recovery curve: well shutdown time, taking into account the initial transition section, taking into account curve change section before well shutdown.The study of variable factors impact on the results is carried out by interval estimation.The mathematical model describing the pressure recovery curve is local and changes its structures. This model can be used in industry conditions.

Before And After

Industrial experiment works (IEW) were carried out to study the mechanism of filtration and reservoir properties changes (FRP) in the process of wells swabbing. Based on the hydrodynamic studies, the results of the works are analyzed. A method for oil production enhancing by reservoirs hydraulic compression has been worked out. In the process of well swabbing the barograms were recorded, pressure recovery curves were taken with the determination of hydraulic conductivity and piezoconductivity values, potential productivity coefficients, well flow rate, reservoir pressure before and after exposure. The interpretation of hydrodynamic studies was carried out by the deterministic analysis with subsequent modeling of the situation. The reservoir, opened by the perforation interval, is of complex structure, as a result of which the liquid was absorbed by the interlayer located above the area with newly formed microcracks. Keywords: hard-to-recover reserves; swabbing; carbonate reservoirs; filtration reservoir properties; pressure recovery curve.

Abstract The method described can determine hydroxy dimetridazole and hydroxy ipronidazole in turkey and swine muscle tissue at levels of 2 ppb. After an initial extraction with ethyl acetate and subsequent evaporation, the samples are solvated in acid and back-extracted. A C18 solid-phase extraction is performed after neutralization of the acidic extract. The basis for quantitation was an external standard containing both analytes. After performing 10 recovery curves with blank control tissue spiked at 0, 1,2, and 4 ppb, the mean recoveries of hydroxy dimetridazole and hydroxy ipronidazole were 61.8 and 64.6%, respectively. Recovery variation was less than 20% for both analytes over all 10 curves. The performance of the extraction method was verified in tissues incurred through the dosing of live animals.
